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 metre long and 1.78 metre wide but just 1.22 metre 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.
Coupled with the Detroit showcar Audi e-tron's low gross weight of around only 1,350 kilograms, high-torque power units driving the rear wheels guarantee commensurate road performance. Two electric motors with a combined output of 204PS and 2,650 Nm (1954.54 lb-ft) accelerate the coupe with ASF-design aluminium body from 0 to 62mph in just 5.9 seconds. The Audi e-tron accomplishes the sprint from 37mph to 75mph (60 to 120 km/h) in a mere 5.1 seconds.
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 driveability 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 centre 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 155 miles realistically possible.
As previously with the first Audi 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.
