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
drivability of a go-kart – agile, good on bends and neutral right up to
the very high handling limit.
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 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
