Audi R8 E-Tron
Statistics at a glance of Audi’s new 2013 all-electric sports car: -
Development value £850,000 per car
0-62mph 4.2 seconds
Top Speed restricted to 124mph
The new 2013 car is now a RWD sports coupe with two motors. However, Audi have only built 10 units to production standards, and these are purely as a shop window for their latest technology and to use for further development.
The strong performance from the two motors is drawn from a Lithium Ion battery located to the rear of the seats. They develop the power and statistics as shown above along with 605lb ft of torque. The cars lightness can be attributed to a plethora of carbon fibre and a revised system for braking. The car is definitely exciting to drive and even makes a very satisfying sound track. The throttle response is fantastic along with the stopping ability. The steering gives good feedback and the car corners like a true sports car should and gives the driver a great level of confidence in the cars ability.
The Audi R8 e-tron has visible touches also of where Audi have tried to stretch the car’s efficiency levels. As an example, the car has flaps in the wheel rims. When the car reaches a speed of 31mph these are automatically closed by centrifugal force which essentially helps reduce the cars drag. Once the car dips below 31mph then they re-open to assist in increasing the air flow and cool the carbon-ceramic brakes. However, despite a sub 1 hour charging time and a claimed range of 134 miles, Audi are continuing to strive for better figures. This is still the main reason that buyers are put off electric cars, so this is unlikely to be in the show rooms in the near future.
