Audi R8 e-tron - Audi\'s answer to Tesla\'s supercar
|   Monday, January 07, 2013
Most car companies plan on launching fuel efficient versions of their vehicles for the mass market and this needs a mix of great technologies and cost cutting measures. Audi has gone a step forward and is planning an electric version of the Audi R8. The new car, the R8 e-tron is expected to hit the market quite soon although Audi has not announced an official date as of yet.

The e-tron is Audi's most ambitious project as of the date and the project had to be postponed in October 2012 as the final reports had not been finalized as of yet.
The plans are expected to be back to the drawing boards and the e-tron is finally expecting to see the face of a new dawn quite soon.
The latest reports coming in state that although the project was under the scanner, it wasn't completely stalled and as a result quite an amount of work was done in the meantime and the engineers have also seen a breakthrough in many areas. The car has seen some exterior styling modifications and the drag coefficient has been increased by 0.17. This makes the vehicle more agile while improving overall efficiency.

Although all of the vehicles from Audi feature the Quattro all wheel drive system, the R8 e-tron is expected to arrive in rear wheel drive only, although the prototype features all wheel drive. This is something Audi needs to work on at the moment. The e-tron will be powered by two electric motors, mounted at the rear of the vehicle, displacing a total of 376 BHP along with 604 ft lb of torque, combined.

The vehicle is expected to touch the 60 MPH mark from 0 MPH in less than 4.2 seconds and this is better by a few milliseconds than the all electric super sports car, the world's first, designed by Tesla. The electric motor is also capable of torque vectoring and this is an important factor which helps the engine turn the motors in a completely synchronized manner and this improves the performance of the vehicle.

Torque vectoring also helps the vehicle keep control in turns and sharp corners and actually help the e-tron keep control at all times. This happens as the individual rear wheels can be controlled by the motor and hence their RPMs can be monitored. Therefore, the turning is more precise. The e-tron features a chassis made out of carbon fiber and this keeps the overall weight down to just 3924 lbs. This is quite efficient, considering the fact that this car is a super car at the end of the day.

The vehicle features use of aluminum and titanium in construction and the roll cage installed in the e-tron is lighter by 35 percent and is made up of total aluminum. This does its bit to keep the weight down and is quite helpful after all. The battery setup weighs 1272 lbs and although this is heavy, this saves a lot of fuel and therefore it cannot be helped.
