Audi Electric Sports Car The E-Tron

Audi is showing an uncompromising purist compact sports car with all-electric drive at the first major auto show of 2010. The Detroit showcar Audi e-tron is the name of this 3.93 meter (154.72 in) long and 1.78 meter (70.08 in) wide but just 1.22 meter (48.03 in) tall two-seater; just a few months after the debut of the Audi e-tron at the 2009 Frankfurt Motor Show, this is now the second electric concept vehicle from the brand with the four rings.

The Detroit showcar Audi e-tron’s low gross weight of around only 1,350 kilograms (2976.24 lb), all thanks to its Audi Space Frame technology (or ASF) and coupled with the high-torque power units driving the rear wheels, the car will guarantee commensurate road performance.

Two electric motors with a combined output of 150 kW (204 hp) and 2,650 Nm (1954.54 lb-ft) accelerate the coupe with ASF-design aluminum body from 0 to 100 km/h (62.14 mph) in just 5.9 seconds. The Audi e-tron accomplishes the sprint from 60 to 120 km/h (37.28 - 74.56 mph) in a mere 5.1 seconds. The top speed is limited to 200 km/h (124.27 mph), as the amount of energy required by the electric motors increases disproportionately to speed. The range in the US's National Emission Ceilings Directive (NECD) combined cycle is approximately 250 kilometers (155.34 miles).

The Detroit showcar Audi e-tron is able to distribute its electric motors’ high torque between the wheels entirely as required. Its “torque vectoring” is the key to a thrilling level of active precision and excellent traction. Thanks also to its low weight, short wheelbase and perfect weight distribution for dynamic handling, the Audi e-tron has all the drivability of a go-kart – agile, good on bends and neutral right up to the very high handling limit.

Lithium-ion batteries, located for an optimal center of gravity behind the passenger compartment and ahead of the rear axle, make an effective energy content of 45 kilowatt-hours available. This makes an operating range of up to 250 kilometers (155.34 miles) realistically possible.

As for passenger comfort and e-connectivity, a smartphone that can be integrated into the front section of the center console interfaces between the vehicle, the driver and external information sources. The driver can use a suitably equipped conventional smartphone as a car phone, address database, navigation system and video player. At the same time they can also use it as an operating unit for many specific on-board systems in the Audi e-tron. Many phones that are suitable for these functions are already available from various manufacturers.

As previously with the first e-tron concept car shown in Frankfurt, Audi again bases all components in this electric vehicle on an integral concept with many revolutionary details: a heat pump as an efficient means of heating up and maintaining the interior temperature. The drive system, power electronics and battery have innovative thermal management – crucial for maintaining a high operating range coupled with outstanding interior comfort.
