Mercedes-Benz A-Class E-CELL, 2011

The B-Class F-CELL fuel-cell car, Mercedes-Benz now introduces the new Mercedes-Benz A-Class E-CELL as its second electric car built in series-production conditions. The five-seater with battery-powered electric drive meets all the requirements for a family car for everyday use. It is based on the five-door version of the current A-Class, and features a generously dimensioned interior and luggage compartment for maximum versatility. No compromises have been necessary in terms of space and variability, with compact storage batteries that are located extremely well-protected and in a space-saving way in the vehicle underbase. The car's two high-efficiency lithium-ion batteries provide a range of over 200 km (NEDC). The car is powered by a quiet, locally emission-free electric drive with peak output of 70 kW (95 hp), developing a high torque of 290 Nm. A total production run of 500 Mercedes-Benz A-Class E-CELL cars will be built at Rastatt from autumn 2010. The vehicles will be leased to selected customers in several European countries, including Germany, France and the Netherlands.

The 5 doors, 5 seats, the same luggage compartment volume as in the internal combustion engine A-Class (435 to 1370 litres), a 350-kilogram payload measured as per the relevant EC directive and high variability of the interior and luggage compartment: this is what makes the new Mercedes-Benz A-Class E-CELL a family car for everyday use. The sophisticated sandwich structure provides both an extremely comfortable in-car environment and maximum protection for passengers and components in the event of a collision.

Driving pleasure with zero emissions
Along with exemplary safety, optimum comfort and a high level of suitability for daily use, the Mercedes-Benz A-Class E-CELL also offers other strengths not always to be found in contemporary electric cars: agility and driving pleasure. The features are based on a low centre of gravity, partly the result of the installation of the batteries under the passenger compartment, in the "sandwich" structure of the vehicle floor. This gives the car excellent road-holding and sprightly handling characteristics - qualities that clearly set the A-Class E-CELL apart from other electric cars, which often have heavy and bulky storage batteries located in the boot or by the rear seat. Another benefit from this installation location is the provision of best-possible protection against the intrusion of structural components in the event of a head-on collision or impact from the rear. This is because the batteries are located outside the vehicle body's deformation zones. The high-stability characteristics of the sandwich structure of the floor also provide outstanding protection for both battery and passengers in a lateral collision scenario.

High-performance electric drive with long range
The electric drive of the Mercedes-Benz A-Class E-CELL is a permanent-field synchronous unit developing a peak output of 70 kW (95 hp), a continuous power rating of 50 kW (68 hp) and a high maximum torque of 290 Nm, as expected for an electric drive, available right from the first revolution. This makes the A-Class E-CELL an outstandingly assured and dynamic performer on the road, taking just 5.5 seconds to accelerate from zero to 60 km/h. A kick-down function is used to deliver maximum acceleration, according to the current charge level and battery temperature. Maximum speed is electronically set at 150 km/h.

The energy storage units are two high-performance lithium-ion batteries based on high-voltage technology. The advantages of lithium-ion batteries include their compact dimensions and significantly higher efficiency in comparison with nickel-metal-hydride (NiMH) batteries. They offer 30 percent more energy density than NiMH technology, and 50 percent more power density. Other benefits include high charging efficiency and a long service life. The combined energy capacity of the two lithium-ion batteries is a total of 36 kWh. With fully charged batteries, the Mercedes A-Class E-CELL has a range of over 200 kilometres (NEDC).

The Efficient battery cooling system
A special thermomanagement system keeps the high-voltage batteries cooled to within an optimum temperature window. The cooling system is based on a low-temperature cooling circuit. Fluid cooling with a water-glycol mixture ensures a stable operating temperature supporting the high degree of efficiency and the longevity of the energy storage. In very high ambient temperature conditions, the battery cooling system is boosted with the coolant circuit of the air-conditioning system. The electrical drive system and two on-board chargers are cooled with a high-temperature cooling circuit. This circuit keeps the units working at optimum operating temperatures, with maximum power delivery from the drive system. The car's power electronics supply the 12-volt vehicle electrical system via a DC/DC converter with electric current from the high-voltage system. The electronics system also controls other functions such as the heating and air-conditioning systems in order to minimise the load placed on the battery for this purpose.

Flexible charging options
The batteries of the Mercedes-Benz A-Class E-CELL can be either replenished at public charging points or plugged into an ordinary household power socket. A range of charging options are available, including single-phase 230-volt sockets, three-phase sockets in a household wall-box, and public recharging points. Using a single-phase 230-volt network, it takes around eight hours' charging time to accumulate the energy required for a range of 100 km (NEDC). This time is reduced to just three hours in the case of charging from a wall-box or at a roadside recharging point.
Daimler and a number of other European automakers and energy utilities have agreed on standardised charging plugs and sockets, with an ultimate aim of worldwide standardisation. This makes the technology more customer-friendly, and is seen as a key prerequisite for the rapid spread of electric mobility.

The Intelligent charging management
Like the smart fortwo electric drive in its category, the A-Class E-CELL is the world's first vehicle in its class to be fitted with an intelligent charging management system based on "SmartCharge Communication". Via the vehicle electronics system, all relevant information - such as the electricity supply contract identification data - is exchanged with the charging point. Benefits include a convenient, simple and totally reliable billing system.

Other intelligent features of the car include pre-start climate control. While the Mercedes-Benz A-Class E-CELL batteries are being charged at home or at a roadside charging point, the interior can be pre-heated or cooled to a temperature set by the driver. Another function enables the driver to monitor charging progress and therefore the present range available, via the internet or a smartphone, for example.

The Mercedes-Benz A-Class E-CELL electronics also provide for proactive control of the charging operation. So if the electric car is parked for a long period, recharging can be set to take place at times when electricity is cheaper, for example during the night. The intelligent interface in the A-Class E-CELL provides a range of billing, control and monitoring functions, making electric mobility convenient and safe, and therefore very customer-friendly. The vehicle is automatically immobilised on connection of the charging cable to the socket, preventing any possibility of driving off by mistake while charging is in progress. This makes the recharging operation even safer and more convenient for the user.

"Everything under control" when out on the road
To make vehicle handling and control as easy, safe and transparent as possible for the driver, the Mercedes-Benz A-Class E-CELL has its own control and display concept specifically designed for the requirements of an electric car. The multifunction display in the vehicle shows the battery charge status, trip data such as kilometres driven, travelling time, average speed and average fuel consumption, along with the remaining range and residual electrical energy capacity (SoC = state of charge).

Other detail specific to the system is a display of the currently available drive power. Meanwhile, the rev counter normally to be found on the instrument panel is replaced with an indicator showing the instantaneous drive power demand or recovery power. Green, white and red-coloured segments show whether the drive system is currently operating in charge, economy or boost mode.

High-quality equipment typical for Mercedes
The new A-Class E-CELL also has plenty to offer in terms of Mercedes-quality equipment. Standard highlights in the premium quality "AVANTGARDE" version of this innovative electric car include bi-xenon headlamps, COMAND APS, an active park assist for automatic parking and the THERMOTRONIC automatic climate control system. A special additional function is the ability to preset the interior climate during charging, i.e. raising or lowering the compartment temperature according to the weather conditions. The car also has a comprehensive range of safety features, including rear window bags and sidebags, and sophisticated seating and lighting packages.

External features of this battery-powered electric car include the standard polar silver painted body and an "E-CELL" sign in silver lettering on the boot.

Highest safety standards
Mercedes-Benz applies the same high safety standards in the A-Class E-CELL as in all its other series-produced vehicles. The electric drive system has demonstrated readiness for series production in extensive practical testing programs. Key components have also been proven in Mercedes-Benz fuel-cell vehicles, for example, allowing Mercedes engineers to draw on the experience gained from more than 4.5 million test kilometres in everyday use. The integrated safety concept reflects the specific characteristics of the vehicle's innovative drive system. 

 

The Mercedes-Benz A-Class E-CELL are protected with a comprehensive safety concept:

•     All cables are clearly colour-coded, and safety warnings are placed on high-voltage components.
•     Generously dimensioned insulators and special plugs provide full contact protection for the entire system.
•     An electronic controller continuously monitors safety requirements and immediately alerts the driver to any malfunctions in the high-voltage system.
•     All high-voltage components are connected in an electric loop. This means that the high-voltage system is automatically completely disconnected in the event of a malfunction or an accident.
•     The high-voltage system is also automatically completely disconnected when the ignition switch is placed in the "off" position, or in the event of possible faults.
•     The system is continuously monitored for short circuits.
•     An automatic drive disabler activated when the charging cable is connected prevents any possibility of the car being driven off by mistake.

Modular system for electric cars
In line with the strategy used for hybrid development, Mercedes engineers have also developed a modular system for electric vehicles with battery and fuel-cell. The benefits include the efficient use of shared parts in all the brand's electric vehicles. All the key components of electric cars are appropriate for a modular approach - for example, the electric drive of the Mercedes A-Class E-CELL is also used in the B-Class F-CELL. Both energy storage units in the electric A-Class are the same as the battery in the smart fortwo electric drive.

Mercedes-Benz A-Class Concept, 2011

In 1993 Mercedes-Benz ventured into a completely new vehicle class with the revolutionary concept of the Vision A 93. Now the brand is once again presenting a car that might have come from another planet: the Mercedes A-Class Concept is the first heartbeat of a new generation whose expressive design stands for concentrated dynamism. The Mercedes-Benz A-Class Concept is celebrating its premiere at the Auto Shanghai show (21 to 28 April 2011). The technical highlights of this front-wheel drive Concept car include a new, turbocharged four-cylinder petrol engine developing 155 kW (210 hp), a dual clutch transmission and a radar-based collision warning system with adaptive Brake Assist.

A low silhouette and slim window areas: the proportions of the A-Class Concept stand for concentrated dynamism. Its sporty appearance is given particular depth by the interplay between lines and surfaces. "The A-Class Concept introduces the new Mercedes-Benz design idiom into the compact class in a sculptured, light and expressive interpretation," says Professor Gorden Wagener, Head of Design at Mercedes-Benz. "We use the term 'captured energy' to express the sheer dynamism exuded by the A-Class Concept. Our formal sources of inspiration were the wind and waves, as well as aviation engineering, resulting in this "cool" look."

New turbocharged petrol engine, seven-speed dual clutch transmission
But it is not only visually, but also technologically that the Mercedes-Benz A-Class Concept is ushering in a new compact class era at Mercedes-Benz. This front-wheel drive model is powered by a four-cylinder petrol engine from the new M270 series. It was designed for transverse installation, and thanks to direct injection and turbocharging it offers a high performance potential together with minimal emissions and fuel consumption. Other highlights of the all-aluminium engine include injection pressures of up to 200 bar and fast-responding piezo injectors.

The A-Class Concept is equipped with the two-litre variant of the new engine, developing 155 kW (210 hp). This BlueEFFICIENCY unit is combined with the new Mercedes-Benz dual clutch transmission. As a three-shaft transmission, this has seven forward gears which are shifted automatically with no interruption in tractive power. The new transmission is therefore particularly economical, sporty and comfortable.

Exterior design with defined edges and a free interplay with the body surfaces
One major characteristic of the new design idiom at Mercedes-Benz is the expressive interplay between lines and surfaces - which the designers refer to as a "clean" Concept. Thanks to concave and convex surfaces with the resulting light modulation, this creates a unique sculpture-like presence. The A-Class Concept emphatically continues this theme of defined edges and interacting surfaces, which Mercedes-Benz first showed in the F800 Style. The side view is structured by three prominent lines: the front structural edge forms a dropping line towards the rear, while the pronounced shoulder muscle over the rear axle emphasises the car's coupé-like character. A further line extends upwards in front of the rear wheel arch in a sweeping curve. These lines lend more depth and dynamism to the side profile. The door handles are recessed into the doors, and emerge electrically at the touch of a button.

The wing-like structure of the exterior mirrors is suggestive of flow and lightness. Another prominent feature is the open side skirt, which creates an unusual light-and-shadow effect. Reminiscent of a turbine rotor, the large 20-inch wheels reinforce the impression that the Mercedes-Benz A-Class Concept has been shaped by the wind.

The front end of the Mercedes-Benz A-Class Concept is a real eye-catcher. The brand logo appears to be surrounded by a starry sky. Where there are usually apertures or louvres, the radiator grille consists of numerous metallic silver "dots" on black stems. This theme is reflected in the design of the wheels.

The visually wide rear end exudes power and athleticism, and is likewise enlivened by an interplay between convex/concave surfaces and pronounced edges. The tail light clusters continue the lines of the muscular shoulders towards the rear, emphasising the car's width with their horizontal orientation. The aerodynamic spoiler lip in the tail lights improves efficiency, while the diffuser creates a downforce to aid roadholding.

The Interior dominated by associations with aviation engineering
The interior of the Mercedes A-Class Concept, which is flooded with light from the large panoramic roof, likewise appears to be from another planet. Many of the unusual features were inspired by aircraft engineering, at the same time reflecting ideas from the "Mercedes-Benz Aesthetics No. 2" interior sculpture. Various component groups have been reduced to a minimum, for example the dashboard and centre console are merely brushed aluminium structures. The result is a transparent, light, bionic design effect.

As an extremely eye-catching detail inside the A-Class Concept, the dashboard takes the form of an aircraft wing and has a translucent, stretchable textile lining. Thanks to this sophisticated fabric, which is vapour-coated with chrome particles, the bionic cellular structure of the dashboard remains visible - its design is reminiscent of a canvas-covered aircraft wing whose underlying struts are discernable. Dramatic backlighting makes this instrument carrier appear particularly futuristic. Thanks to the translucent high-tech lining and lack of a conventional support structure, the dashboard appears to be free-floating. Its lines continue into the door panelling like vapour trails from the winglets of a jet.

The form of the air vents in the dashboard is likewise inspired by the engines of a jet aircraft. The translucent, backlit vents change their colour depending on the temperature the occupants have selected for the climate control system: they are blue if cool, fresh air is vented into the interior, but red if the airflow is heated. The prominent displays in the instrument cluster, which were inspired by the afterburner of a jet engine, are likewise in red. The central control unit is designed as a high-tech flight panel with a shift lever in the shape of a "thrust control". With their moulded-over head restraints and very pronounced lateral support, the seats call the pilot seat in a jet fighter to mind.
Titanium and silver tones are combined with a light, elegant beige in the interior. Magenta is used to produce highlights that contrast with the car's alubeam silver paint finish, which follows the dynamic contours of the exterior like liquid silver.

The Mercedes-Benz A-Class Concept makes use of modern materials such as the high-tech lining on the dashboard, or metallised leather where semi-aniline is dyed with metallic pigments and embossed, and also high-grade nubuk leather. This builds a bridge between 125-year tradition of the Mercedes-Benz brand and its claim to progressiveness.

COMAND Online with revolutionary graphic design offers ease of use for smartphone applications
A smartphone is fully integrated into the operating systems of the Mercedes-Benz A-Class Concept. When the phone is inserted into the recess provided in the centre console, it is automatically synchronised with the COMAND multimedia system. All the functions of the smartphone, including internet radio, email and social networks such as Twitter or Facebook, are shown as applications on the 17.8 cm display and can be operated via the rotary/push control.

The visual presentation of the screen elements is unique, with a deep, three-dimensional look created by laser-like, magenta-coloured lines. This near-series display Concept was designed and realised by designers and engineers at the Mercedes-Benz development laboratory in Palo Alto/USA. The menus in the Mercedes-Benz A-Class Concept are in both Mandarin and English.

The headlamps with optical fibres produce a unique effect
A very special effect is created by the lights of the Mercedes-Benz A-Class Concept, as the innovative full-LED high-performance headlamps repeat the starry sky motif of the radiator grille with numerous lighting points. The daytime running lamps consist of 90 optical fibres with aluminium sleeves, and they are arranged in a wing-shape within the headlamp. The tentacle-like fibres form individual, diffused light sources to create a dramatic contrast between soft and harsh.

From any perspective an unusual effect is also created by the LED indicators, which appear to float freely within the headlamps like an enclosed air bubble in a perfume bottle. The indicators are mounted in six chambers at the top of the perspex headlamp unit, and their vapour-coated reflectors remain invisible.

The Mercedes CLS, the LED high-performance headlamps of the Mercedes-Benz A-Class Concept combine the Intelligent Light System with LED technology. The projection module of these LED headlamps is no longer round, but rather flatter and more sporty. This sporty impression is reinforced by the matt carbon-fibre housing, which contrasts with the aluminium surround of the projection module.

The optical fibres with aluminium sleeves are also used in the tail lights. 120 optical fibre lighting points form each C-shaped tail light cluster to create a unique visual effect with their subtle glow. They are appropriately lit up for the brake light function. When braking, the continuous light band between the two tail light clusters also lights up to make the Mercedes A-Class Concept appear even wider. The indicators are self-contained elements in the centre of the tail lights. The base unit of the tail light is of carbon-fibre, with the numerous red elements ensuring visual depth.

New assistance and braking system reduces the risk of rear-end collisions
In the A-Class Concept, safety pioneer Mercedes-Benz is showing another milestone in the democratisation of automotive safety technology: the concept car is equipped with a radar-based collision warning system with adaptive Brake Assist - a world first in the compact class. This system gives a visual and acoustic warning to a possibly inattentive driver, and prepares Brake Assist for an absolutely precise braking response which is initiated as soon as the driver emphatically operates the brake pedal.

McLaren MP4-12C GT3, 2011

The McLaren GT, a new race car manufacturer which brings together the expertise of McLaren Racing, McLaren Automotive and CRS Racing, unveiled the McLaren MP4-12C GT3 race car and plans for a 2011 development programme.

The new McLaren MP4-12C GT3 will be the first McLaren car built for FIA GT series racing since the McLaren F1 GTR finished production in1997. The 12C GT3 is based on the new MP4-12C high-performance sports car and a team of engineers, designers and test drivers with vast experience in Formula 1 and GT racing has been assembled to undertake the process of adapting the carbon chassis-based 12C to racing specification.

Drivers and FIA approved races confirmed for 2011
McLaren GT aims to deliver the highest quality, most reliable and most driveable car on the GT3 grid when 20 cars are delivered to privateer teams for racing in Europe in 2012. The unique combination of McLaren and CRS Racing's technology and development methodology is matched by McLaren GT's appointment of experienced and successful racing drivers to develop the 12C GT3 at challenging races over the 2011 season.

McLaren GT plans to debut the new McLaren MP4-12C GT3 at this season's Blancpain Endurance Series race at Spain's Circuito de Navarra, followed by Magny-Cours in France and Silverstone in England. As part of the development programme for the 12C GT3, McLaren GT also expects to enter the Total 24 Hours of Spa endurance race.
CRS Racing Team Principal Andrew Kirkaldy will be joined by 2010 Vodafone McLaren Mercedes test driver Oliver Turvey and Portuguese racing driver Álvaro Parente in the McLaren GT driver line-up for the 2011 development programme.
McLaren fans eager to see McLaren's first GT racing car since the legendary McLaren F1 GTR can expect to see the new 12C GT3 driven up the famous Hill at Goodwood Festival of Speed from 01-03 July 2011.

McLaren MP4-12C GT3 development targets
McLaren GT comprises a team of designers, engineers and test drivers with vast experience in developing successful race and road cars. Marcus Waite, McLaren GT Chief Engineer, began his career working with the McLaren Formula 1 Simulation Group. A move onto the Formula 1 team where he was Senior Test Team Engineer for many years was then followed by his appointment to McLaren Automotive as Test Team Leader responsible for the new MP4-12C sports car. Combining practical experience of Formula 1 car development methodology and a deep understanding of the 12C road car's technical specification is invaluable to McLaren GT.

The McLaren MP4-12C: The essence of a race car
Racing experience and development tools have played a key part in readying the 12C GT3 for its 2011 race programme. But, before the racing car takes to the competitive grid, McLaren, in the form of McLaren Automotive set out to develop a high-performance sports car that set new standards for speed, handling, efficiency, braking and driveability: formed from an obsession for aerodynamic purity and lightweight engineering. Assets and goals that make the McLaren MP4-12C a perfect road car from which to develop a race-winning GT car.

Once plans were agreed to take the 12C racing, key members of McLaren Automotive's design and engineering teams were eager to support this natural step at McLaren.
Under the McLaren Orange skin, the 12C GT3 shares the same 75kg carbon 'MonoCell' chassis as the 12C road car. Since the modern McLaren was formed in 1981, the company has used only carbon fibre for the chassis construction of all its road and race cars: it was a natural choice for the heart of the MP4-12C. Lightweight construction and manufacturing innovation through Resin Transfer Moulding was a priority for the engineers and designers responsible for the 12C's chassis. The result is a road car that, at 1301kg, is the lightest in the 'core' sector of the high-performance sports car market.
Andrew Kirkaldy said: "I believe the MP4-12C is an engineering masterpiece and that starts with its carbon chassis. A rigid chassis is hugely important to a racing driver. The McLaren MonoCell is unequalled as a safety cell, and our engineers can be sure that any changes made to the chassis set-up will have the desired effect because of its structural rigidity and predictability.

The CRS Racing to deliver on expectations of a new McLaren race car
The prevailing design concept of the new McLaren MP4-12C road car is 'designed around the driver', and this is just one example of McLaren's uncompromising commitment to offering a new driving experience in road and race cars. CRS Racing Team Principal Andrew Kirkaldy brings a decade of GT-level racing experience to McLaren GT and, as the team's project manager, Kirkaldy was able to specify the cockpit and other attributes of the 12C GT3 to ensure restrictions normally associated with GT3 race cars are removed from the McLaren.

Specification and performance reflect McLaren expectations
Just as with the 12C road car, McLaren is working closely with specialist suppliers to deliver an innovative and lightweight car. The 3.8-litre McLaren V8 twin turbo 'M838T' engine supplied in the road car also features in the 12C GT3, but de-tuned to 500 PS (from 600 PS) in order to provide optimum power for this performance-balanced race car.

The new McLaren MP4-12C GT3 will feature a unique engine calibration, bespoke racing transmission developed in partnership with Ricardo (who also developed the engine with McLaren) and a suspension arrangement tuned specifically for racing.
McLaren GT has selected the TAG-400 Engine Control Unit for the new 12C GT3. The TAG-400 is a compact, self-contained engine management system and data logger for race engines designed and built by McLaren Electronic Systems. The procurement of components from suppliers used to working with partners in Formula 1 is another example of McLaren GT delivering on its objective to build a GT3 car of unrivalled quality and reliability.

Ferrari P540 Superfast Aperta, 2011

 

 

Ferrari P540 Superfast Aperta, 2011

The first shake-down has been held at Fiorano of a very special one-off, the Ferrari P540 Superfast Aperta, built for an American client. The car, the second in a new Special Projects programme created by Ferrari to meet requests from the most discerning clients and collectors to create truly unique models, is based on the Ferrari 599 GTB Fiorano and was inspired by a Carrozzeria Fantuzzi-designed Ferrari built specifically for the 1968 Fellini film, Toby Dammit, itself inspired by one of the tales of Edgar Allan Poe.
 

With the Special Project's approach to producing such individual one-offs, the Ferrari P540 Superfast Aperta respects all existing international safety and homologation requirements and is thus road legal. The car was designed by Pininfarina and built in Maranello, and the client was directly involved in each stage of its development. As the 599 GTB Fiorano donor car is a coupé, considerable effort went into strengthening the chassis by using finite element analysis in development and the increase in weight was kept down to just 20 kg by employing carbon-fibre extensively. From the initial sketches to the final, road-legal car took just 14 months.

Audi A1 e-tron Concept, 2010

 

 

 

 

 

Audi A1 e-tron Concept, 2010

The new e-tron model series from Audi will gain another new member at the 2010 Geneva Motor Show: The Audi A1 e-tron Concept is a Mega City Vehicle (MCV) with an innovative drive technology. It comes equipped with a powerful electric motor for zero-emission driving in the city. There is also an internal combustion engine on board that recharges the battery in exceptional circumstances. The Audi A1 e-tron Concept is very agile thanks to the 75 kW (102 hp) peak power of its electric motor.

The technology of the Audi A1 e-tron

The e-tron model family from Audi is just a few months old, but it already has a number of members, for each of which Audi has chosen a different drive technology. The first e-tron, which debuted at the 2009 IAA in Frankfurt/Main, is a near-series high-performance sports car with electric motors for all four wheels. The study shown at the Detroit Motor Show in 2010 is a lightweight, compact two-seater with two electric motors on the rear axle.

The Audi A1 e-tron Concept now presents another approach - a compact electric car in the premium class. The four-passenger, two-door MCV city car was designed specifically for use in the metropolitan areas of Europe and North America and in the rapidly growing megacities of Asia and South America. The Audi A1 e-tron always drives on electric power; its internal combustion engine is only used to recharge the battery in isolated cases.
Audi A1 e-tron Concept

The integration of the new technologies shows the holistic approach that Audi is pursuing with electric mobility. The objective is to use the energy with the lowest possible losses. The precise interaction of the components, their intelligent packaging, and the efficient management of the current flows are the product of the expertise that the company has developed in this area.

Audi has developed a proprietary thermal management system to keep the battery, the electric motor, and the power electronics within their respective ideal temperature windows.

Behind the three e-tron models is a broadly diverse and modular technology platform that continues to grow very rapidly as Audi drives development forward.

The electric motor: 75 kW (102 hp) peak power

The synchronous electric motor of the Audi A1 e-tron is mounted transversely at the front of the car. Its low mounting position has a positive effect on the vehicle's center of gravity. Continuous output is rated at 45 kW (61 hp), with peak power of 75 kW (102 hp) available in short bursts. 150 Nm (110.63 lb-ft) of torque is continuously available, and peak torque is 240 Nm (177.01 lb-ft).

The electric motor sends its power to the front wheels via a single-speed transmission. The elegant, retractable selector lever on the console of the center tunnel used to choose between "Drive," "Reverse," and "Neutral" was taken from the first Audi e-tron.

The power electronics are mounted in the engine compartment above the electric motor. The most important components are the pulse-controlled inverter, which serves as the controller between the electric motor and the battery; the DC converter, which connects the high-voltage network with the 14 volt electrical system; a breaker unit to protect the high-voltage components; and the charging module. The socket for the standard charging plug is located behind the rings in the single-frame grille of the Audi A1 e-tron. A fully depleted battery can be recharged in approximately three hours from the 380 volt grid. A display immediately adjacent to the plug-in connection shows the current charge status and the charging time remaining.

The concept of the innovative Mega City Vehicle requires the electrification of key auxiliaries. The refrigerant compressor of the climate control system, for example, is electrically powered by a high-voltage electric motor that supplies only the amount of power needed at the time.

This increases system efficiency substantially compared to conventional concepts. Thanks to a special circuit, the climate control loop also functions as a heat pump that regulates the temperature of the cabin and the battery.

The power steering of the Audi A1 e-tron is electro-mechanical and thus particularly energy-efficient. An electronic brake system makes it possible to tap into the recuperation potential of the electric motors. A hydraulic fixed-caliper brake is mounted on the front axle, with two novel electrically-actuated floating-caliper brakes mounted on the rear axle. These floating calipers are actuated not by any mechanical or hydraulic transfer elements, but rather by wire ("brake by wire"). In addition, this eliminates frictional losses due to residual slip when the brakes are not being applied. In addition, the servo unit received a new, demand-controlled electric vacuum pump.

The large electric motor powering the Audi A1 e-tron Concept can convert braking energy into electric current and feed it back into the electrical system. The high degree of recuperation benefits overall efficiency. The electric control actions are imperceptible to the driver, who notices only the familiar, precise, and perfectly controllable pedal feel.

The battery pack: a compact T arranged below the floor

The energy storage unit is arranged below the floor, where it is ideal for the center of gravity and weight distribution. The battery pack is shaped like a T, with the short "transverse beam" filling the rear section of the center tunnel and the "cross-beam" filling that area in front of the rear axle where the fuel tank is otherwise located. The 380 volt lithium-ion rechargeable battery has a nominal energy content of 12 kilowatt hours. It comprises 96 prismatic cells and weighs less than 150 kilograms (330.69 lb).

The Audi A1 e-tron can drive 50 kilometers (31.07 miles) emission-free in city traffic on the powerful battery. On longer trips, the battery is recharged by a particularly compact internal combustion engine mounted below the luggage compartment.

The range extender

The Audi A1 e-tron Concept car has a Wankel engine as a range extender, but other compact concepts are also possible. The small single-rotor Wankel has a chamber volume of 254 cc and runs at a constant 5,000 rpm in its peak efficiency window. The electronics also consider navigation data such as the destination and route profile to automatically activate the range extender as needed. The driver can also turn the range extender on and off as necessary with the push of a button The fuel tank holds 12 liters (3.17 US gallons).

The great strengths of the Wankel engine are the nearly vibration-free and quiet operation, the small dimensions, and the extremely low weight. Together with the generator, which is powered by the Wankel engine and produces 15 kW of electric power, the complete assembly weighs only around 70 kilograms (154.32 lb). This weight also includes the special power electronics, the intake, exhaust, and cooling unit, plus the insulation and the subframe.

Concentrated driving pleasure: the sportiest car in its class
The sporty, agile chassis of the Audi A1 places it at the head of its class. Whether in the city, on an interurban road or on the highway - the Audi A1 is great fun to drive anywhere thanks to its sporty setup, the optimized weight distribution and the very direct steering. The standard ESP stabilization system with electronic axle-differential lock makes the handling of the Audi A1 even more sporty and precise, while driving safety is increased even further.

The new Audi A1 also sets new efficiency standards. Audi is sending the new model line into the fray with four four-cylinder engines, with the two TDI and two TFSI gasoline engines producing between 63 kW (86 hp) and 90 kW (122 hp). All of the engines follow the downsizing principle - they substitute turbocharging for displacement and draw their fuel through direct injection units.

All versions of the Audi A1 impress with good fuel economy, with standard cycle values between 3.8 and 5.4 liters per 100 kilometers (43.56 - 61.90 US mpg) (provisional values). The 1.6 TDI with 66 kW (90 hp) and manual transmission emits only 99 g of CO2 per kilometer (159.33 g/mile). All of the engines are equipped with a recuperation system that allows them to recover energy during braking, and are coupled with an automatic start-stop system. A new temperature management system with switched water pump contributes to the low fuel consumption of the 1.2 TFSI.

High-tech and efficiency: the seven-speed S tronic
At Audi, efficiency is always high-tech. The Audi A1 is available with the seven-speed S tronic transmission. The dual-clutch transmission changes gears extremely quickly, comfortably and without detectable interruptions in pulling power. It offers both automatic and manual modes, with paddles on the steering wheel available as an option. It provides for tremendously fun driving and also further reduces fuel consumption - typical Audi.

The Audi A1 is sporty, powerful and attractive. As a newcomer in the compact segment, it appeals to a modern customer group - a young, urban, lifestyle-oriented public. Audi A1 customers - many of whom are expected to be women - are interested in design, music, fashion and sports. The entry-level model will be priced at around 16,000 euros.

Design
It has a confident road stance - powerful, distinctive and full of character: The Audi A1 is both the premium option and the athlete in its class. The pronounced encompassing shoulder line, the color-contrasted roof arch and the unusually sharply sloping C-pillars give the three-door an unmistakable silhouette. The dimensions also document the dynamic lines: 3.95 meters (12.96 feet) long, the latest model from Audi is an impressive 1.74 meters (5.71 feet) wide but only 1.42 meters (4.66 feet) tall. The wheelbase measures 2.47 meters (8.10 feet); the overhangs are correspondingly short.

The design of the Audi A1 is tightly integrated into the brand's design language and unique in the compact segment - emotional, bold and progressive. Audi has a reputation for taking a lot of ideas and innovations from its concept cars into series production, and the Audi A1 continues this tradition. Many of the features and innovative ideas from the 2007 Audi A1 project quattro showcar have already made it to series production in the Audi A1.

The front end bears an unmistakable family resemblance, but features unique accents and innovations in the details. The single-frame grille, for example, is harmoniously integrated into the front end and with its angled top corners represents a new evolutionary stage. Its braces are arranged horizontally to emphasize the width of the front. The large, plastically modeled air intakes with their horizontal bars also contribute to the sporty appearance of the Audi A1. The fog lights are located in their outer corners.

The three-dimensionally styled headlights also have their own special look. The Audi A1 looks determined and concentrated to the road. A strongly curved wing structures the interior of the headlights. As with every Audi, the daytime running lights are standard. With the optional xenon plus units, the daytime running lights are implemented using LEDs and a light guide. They appear as a homogenous strip that traces the wing.
