Time to put the electric showpiece to the test. Getting in is a challenge not only because of the concealed door handles but also due to the narrow door aperture and the restricted adjustment of the space-age bucket seat. The airy cockpit has a jet-fighter touch, with hard-to-decipher LED monitors instead of rearview mirrors; a dished, flat-bottom steering wheel; and various iPhone-style touch pads instead of push buttons. Hit the start button, and the gear lever rises from its flush sleeping position like the head of an angry cobra. I select D, but nothing happens. To save energy, the E-tron doesn’t crawl, so you don’t have to hold the car with the brake. At the first stab of the accelerator, the Audi takes off like a noiseless red arrow, but the quoted 0-to-62-mph time of 4.8 seconds is at this stage strictly theoretical, since the concept car weighs some 1300 pounds more than the target, and it’s muzzled by a speed limiter. In finished form, the E-tron will accelerate with no holds barred from 0 to 85 mph, at which point the system starts to ease off because of the rapidly increasing aerodynamic drag and rolling resistance. The top speed will be capped at 125 mph.
