"Think of it as Audi�s vision of what a sports car below the R8 might be like. Ingolstadt hopes to have its own version of VW�s Bluesport roadster - this is the much-mooted R4.
E-tron is just 3.93m long (the Bluesport measures 3999mm) so it�s shorter � as well as lower and narrower � than a TT. Unlike the four-motor, four-wheel drive E-tron unveiled at the 2009 Frankfurt show (earlier post), this E-tron has just two motors and rear-wheel drive. Still, the two electric units (mounted on the rear axle) combine to produce 1955lb ft � down from big brother�s 3319lb ft � and 201bhp so the E-tron is propelled to 62mph in just 5.9 seconds. Together with the smaller shape, aluminium spaceframe and carbonfibre-reinforced plastic body, the E-tron weighs just 1350kg, versus 1600kg for the original E-tron.
The lithium-ion batteries that power the E-tron are mid-mounted and tip the scales at 399kg, giving the show car a 40:60 front-to-rear weight distribution. With the car�s top speed limited to 124mph, their 45kWh capacity gives a 155-mile range."
