I’ve driving Audi’s all-electric It was huge fun. Well, been a long time And after all that, it’s not going.

If you’ve a long you might remember a concept 2009 simply called the e-tron. It looked slightly an R8 but it wasn’t. The body was very — it was even a different — and it had pure-electric drive.

of the four wheels had their own Audi said it would go on in 2013.

Rash thing to During development the concept got down, so finally it’s RWD (though more powerful originally planned), and uses a the same size and shape as the — although a quarter of it is to cut the weight. And then they it wouldn’t, after all, go on

They’ve built ten fully-developed they’re road-legal, and they be used in trials to gather on battery performance and electronics. parts are modular across the VW group, so it’s good Even so, it’s not the original

Anyway, let’s enjoy it we can.

There are two motors in the of the rear, and each drives one They aren’t mechanically so there’s no diff. Each makes 140kW (190bhp) so 380bhp in all.

At low speed all the acceleration the tyres can use, and disappears in 4.2 seconds, but the acceleration peter out towards the motors’ rev at about 150mph, so instead the car is to 125mph for efficiency’s sake.

weight is 1780kg. The chassis is chocka with exotic to cut weight versus the standard R8. The engine and gearbox are absent of too. But that doesn’t the mass of the huge battery.

At least it sits low and centrally in the so it isn’t bad for cornering.

The battery is so big it 14 hours to charge off the normal — that’s why there’s a too. It gives a range of 135 in the standard drive cycle but they admit it falls to 100 in quick road driving. As an test, they went to the started with it fully did two laps flat out (just 16 minutes) and didn’t have the to complete a third.

Sure the e-tron scoots away a standstill with jet-plane — smooth, controlled but very strong. The noise is a sci-fi hum, rising in but not volume as you gather speed. In mode, there’s not much braking when you lift the but you can dial that up using paddles if you like.

Regeneration also gets if you select dynamic mode, feels like early into a corner.

The braking is fiendishly complex. There’s braking at the rear, computer-controlled to the hydraulic brakes at the front. So it up to 0.45g. If that’s not enough, or if the is already full and can’t regenerated energy, there are electrically actuated discs at the

Amazingly, it all feels well-integrated, and natural.

In eco mode, cornering is a bit There’s no roll to speak of and OK, but it’s a strange combination of high-geared steering and a strong to understeer in the tight corners of the course, especially in the early of the bend.

Ah, but then you can summon some Four-wheel-drive was discarded by the engineers as too in a car where every gramme the range. Instead they full torque vectoring those rear motors.

the dial away from the eco and feel its magic.

The early-onset is gone. Instead the car feels far eager and lighter as it swivels the corner. The inside wheel is slightly dragging that back, pivoting the car into the

On the way through and out of the curve, the outside is given extra torque, right at the limit of traction, and the one gets torque variation to the car on the course you’ve set with the

It works amazingly well, and yet the car natural, easy to predict and Switch the ESP to ‘sport’ and it’ll drift a bit. It’s how quickly the e-motors can react to circumstances: far faster and more than using brakes or and reinstating the power in normal ESP

Even more astonishing is how the of the chassis is being altered by as you change settings.

Mercedes AMG a similar torque-vectoring trick the individual wheel motors in the SLS And that car has four of them, for Hmmm. AMG has built a car that more of an Audi than the Audi does.

Maybe why the R8 e-tron got stopped so near to

But Audi boss Wolfgang gives other reasons. We are a company. Our customers don’t to miss out on any day-to-day desire.

The he refers to is that of arriving at destination. He means that stuck by the roadside with a battery isn’t a premium

He also says the R8 e-tron be too expensive to build — all carbon, all that battery. means it would have to at a loss. If we used the A3 and A4 to subsidise a well that’s not very to those customers, he says
