Audi E-Tron Concept

tries to win us over with electric supercar.

Today#x2019;s machine tells us that power is to the internal-combustion engine jets were to the propeller-driven Jet engines, of course, provided clear advantages over the engines they replaced#x2014;foremost, offered higher speed.

But an electric motor make a car run or better than an internal-combustion Probably not now, and at least not to justify putting up with its disadvantages. But electric cars are to be better for the earth, and with the movement taking on a quasi-religious many folks feel increasingly important to make a of #x201C;true believer#x201D; status to communities.

Given that, cars#x2014;which have been far longer than the jet engine#x2014;may take off.

But if that#x2019;s the case, we damn want them to be fun, and supercars like this E-Tron and the upcoming battery-powered SLS AMG are decent places to start. they#x2019;re bare-faced attempts to woo into the green-car fold, but if you to drink the Kool-Aid, you#x2019;ll the Kool-Aid. We had an opportunity to take an prototype for a spin and to grill about the project.

The car you see here#x2014;and the one we the first E-Tron, the bright-red that was shown at this Frankfurt auto show, as a display car and as a development tool. has since built a second, car that it showed off at the Los Angeles show .

For driving, Audi the multispoke 19-inch wheels in Frankfurt with the 19s from the R8 which brings the E-Tron closer to the mid-engined supercar it really is. Yes, the basic is related, but the E-Tron is more and the stylistic and technical differences are

Four Electric Motors = Vectoring

Most important, the is powered by four electric rather than a gasoline Although the maximum output of 313 hp is to what we#x2019;ve reported the overall torque output of 502 is significantly less than the lb-ft Audi initially Credit the company#x2019;s multiplication of through the E-Tron#x2019;s drivetrain, than reporting the motors#x2019; output, for the discrepancy.

The four each drive one wheel and can be independently, thus offering functionality. This extra of agility is a boon for masking hand-assembled prototype#x2019;s 4400 production target weight is over 3500#x2014;which includes the lithium-ion battery unit. at 53 kWh (only 42.4 kWh of which are used to prolong service the battery takes 2.5 hours to with a special 400-volt outlet. Figure a half to a day of recharging time at your 110-volt household outlet.

A full charge will get you 150 miles on the road, Audi

Before you take off, you witness a remarkable display of and futuristic design. A silver moves upward on the dashboard; the selector needs to be pushed to initiate takeoff. Buzzing and ensues, and then you are cleared to go.

the accelerator, and the E-Tron charges with extreme urgency more impressive by the near accompanying it. Audi says 0 to 62 mph 4.8 seconds. As with the Tesla the effect at low-to-midrange speeds is in a surreal way. Low and midrange are all we can report on right now; the prototype, which we drove on a of California#x2019;s legendary Highway 1, was at a mere 70 mph.

But that#x2019;s the ideal speed anyway. Based on our experience other electric cars and with engineers, we believe the experience at higher velocities be less exciting. When the curves drop at higher electric cars become and the E-Tron#x2019;s theoretical top speed of 124 mph give you any bragging rights, It seems too slow for a supercar as this, but it helps save life, and it lets Audi do a second gear.

Getting a transmission to work reliably on a electric car is no small feat, as has found out the hard way.

Very Refined

The level of in the E-Tron impressed us, and the contrast the Tesla roadster is striking. the Tesla, which has been in for some time, still like a prototype, the E-Tron and acts like a finished The flawless execution bears to the perfectionism at Audi, which German carmakers struggle to

Mercedes, which has a stake in now has a lofty benchmark for its electric

That electric SLS AMG will of be the E-Tron#x2019;s closest competitor. 525 hp, the Benz will produce more power, but it will a shorter range of about 100 Audi will launch the in 2012 at a price of about We think Audi#x2019;s approach of a dedicated model makes sense than AMG#x2019;s SLS, since it gives you bragging rights without the to point at the #x201C;electric#x201D; badge.

In any event, let the electric games make the cars fun,
