The Audi R8 is a genuine electric supercar, and a prime demonstration of the limitations of power.

Consider the performance: to 100km/h in 4.2 seconds, and an electric car lap of the tortuous Nurburgring in 8:09

Then consider the range: 215 kilometres, but at that speed not more than two laps of the kilometre Nurburgring.

And if that turn you off, ­­the version of the R8 costs considerably to build than anything in the range, which is already the $400,000 mark.

Why so expensive? The technology to keep the batteries at temperature, to cite just one takes up most of the nose and like scientific equipment a Mars mission.

Audi recently announced although the R8 e-tron (in Audi-speak, means anything powered by other than a conventional or diesel engine) is production-ready, it make it to showrooms. It simply possible to cover costs.

a chance to drive the car (just Robert Downey jnr in Iron Man 3 ) and to the engineers was not to be missed.

Audi much of the technology will it into other production though the company seems to be more towards “range cars, which we’ll to shortly.

The location for the R8 e-tron was Berlin’s mothballed Tempelhof which was the busiest in the world in receiving wait for it 11,000 Later it was the centrepiece of the Berlin and one of the US planes involved is still on

On a couple of spare hectares of a temporary test track had marked out, while in a part of the kilometre-long terminal various displays gave into Audi’s alternative plans.

Clever technology

Clever tech includes wheel covers that at speed to lower air resistance, and a rear view mirror in the This uses a camera, on a glass screen at the rear, and limit the all-up weight to kilograms (that’s still 200 more than the V10 R8).

Ten examples have been all in bright orange, with carbon-fibre “sideblades”.

Noise factor

The acceleration is though not silent. Aside the noise that comes putting 280 kilowatts through the tyres, there is an engine It comes through the sound however.

It’s synthesised, to a sportier feel.

From first corner it was mainly a track, but with sufficient straights to demonstrate the e-tron’s torque. This torque the need for a gearbox.

During tyre noise is by far the loudest (the synthetic engine cuts out at 60km/h). The central allows you to adjust the driving from “efficiency” through to and “automatic” (which toggles the two depending on your driving).

It is easy to control, with turn-in, particularly when the system gives extra to the outside rear wheel cornering (it cuts out in “efficiency” to save the batteries).

Massive stopping power, and braking, are provided by the large ceramic brake rotors. the lack of engine noise is a the rubbing of pad on brake is so loud swear there is damage done.

E-tron A1

The R8 e-tron is made and a delight to drive, but is a market for such an expensive with such a limited Audi doesn’t think so, not batteries are lighter, cheaper and more charge.

The solution? It may be a smaller, lower performance car with fewer batteries and a petrol (or diesel) engine in

This small hatch has built in low volume for testing in cities and is a precursor to an A3 e-tron vehicle, which will go on in Europe next year and in in 2015.

The A3 has a conventional engine in its but the A1 has a tiny Wankel rotary in its Why use a Wankel, famous for its high use? Because the idea is not to use it. it an emergency life raft if you run out of

It is not connected to the wheels, it’s to recharge the batteries. And being a it is very compact for its power

Most commuters should be to do their daily drive the 50 kilometre range of the batteries, and in overnight.

There is an eerie when you push the start but beyond that it feels like a conventional, if slightly small hatch to drive. is no trouble keeping up with traffic: the motor develops 85 and 300 Newton metres; 0-100km/h 9.8 seconds.

The cabin is unaffected by placement and even the boot is a size, despite there an engine under it. There are few compromises, other than the of a highly elevated purchase

After half an hour of in Berlin traffic, the display me I had 19 kilometres left on the batteries. was no need for “range anxiety” as total range is 250 kilometres thanks to the Wankel engine and its fuel tank.
