the outside it has the same lusciously profile as the R8 supercar. The only that something might me about the R8 e-tron is the cooling-air in the hood, and the absence of tail Although they look identical, the two cars share nine common parts.

the R8 e-tron gets moving, its silence is a giveaway to its electric system.

Of course if you were to the bright red paint from the you’d also notice a large proportion of the outer is made from lightweight fibre. Lift the body and you’ll find a very aluminum chassis—even the suspension springs are made of fibreglass-reinforced The body structure weighs 199 kg, 23 kilos lighter than the of the R8.

All of these weight-saving measures are to compensate for the 530-cell lithium-ion pack, which runs the centre of the car and spreads out in a T behind the The R8 e-tron weighs in at 1,780 kg, a 155 kg heavier than the R8 V8 Coupé a manual transmission. One benefit of the R8 is that most of its weight is very low in the chassis which it a significantly lower centre of

Two 140 kW electric motors are located at the axle, one driving each wheel through a planetary Combined the motors produce 380 and an incredibly potent 605 lb.-ft. of which is available as soon as the begin to spin. Torque is increased through a gear in the planetary gearset, giving the R8 the capability to accelerate from 1 to 100 in just 4.2 seconds.

That’s just two tenths shy of the km/h time of the 525-horsepower R8

Electric power has its limitations, and top speed is restricted to 200 km/h. The R8 is capable of attaining 260 km/h restriction, but running at any speed 200 km/h would drain the in a matter of minutes. Driving the R8 e-tron has a range of 215 km, which is near the potential 425-km of the Tesla Model S, but it is more the i-MiEV and Nissan Leaf.

Charging the drained batteries 12 hours at 230 volts AC.

As with all cars, regenerative braking to slow the R8 e-tron down speed, but for serious stopping there are large, hydraulically carbon-fibre ceramic front Things get interesting in the rear, electromechanical-screw disc brakes are These brakes are electrically for high precision and they power to the rear wheels for vectoring capability in turns.

Well, the first thing notice about the R8 e-tron is the eyeball-squashing acceleration, which even more impressive of the seamless power delivery. In it almost sounded like it had a engine when accelerating from a stop because of the produced by the tires as they for grip, and by the mechanical growl of the gearset as it transferred all of that to the ground.

Corner-exit drive is beyond reproach due to the car’s low of gravity, which favours weight transfer. The R8 e-tron the short twisty course a toy slot car, with steering precision and phenomenal in corners. As a lapping toy, car is truly hard to beat.

The only thing missing is the of an angry V8 or V10 put an accent on the experience.

The thing about the Audi R8 is that no matter how much you can afford to spend to add it to your of exotic sports cars, never be able to buy one. Audi began the project the intention of making it a production it has proven too expensive to produce and the was dropped. That’s not to say that of the electric technology won’t to other cars, and Audi be bringing the A3 e-tron hybrid to in 2014, so not all is lost.

When how much it cost to produce the R8 the answer was unequivocal: “It is not economically to produce.”  That’s a shame because aside from its top speed, it is truly an exhilarating to drive.
