Another version of the Audi R8 e-Tron concept will be present at IAA. This one is said to be the real deal.

Audi has already confirmed they will launch this electric supercar in 2012, so this version must be the production car, save a few minor details. If it weren’t for the vented bonnet and the new grilles, you couldn’t tell the e-Tron apart from the petrol-powered R8.

If the production e-Tron stays loyal to the concept, just like its design, then it will feature four electric motors each powering one of the wheel. Like that you have a four-wheel-drive car with total output of 308 hp, and theoretical torque of 4500 Nm, zero emission, with a range of about 250 km, and 0 to 100 km/h sprint time of nearly 5 seconds.

The R8 e-Tron is the most advanced electric car to be launched next year, but even it fails to address the main problem with EVs: charging time. Even with a rapid charger it still takes 2 and a half hours to recharge an e-Tron.

In 2012 Audi will also introduce a facelifted version of the normal R8.
