Audi E-Tron Detroit Concept
The first e-tron concept was itself slightly smaller than Audi’s righteous R8 sports car. This version, unveiled in Detroit, has smaller measurements than Audi’s own TT. Riding on a 95.7-inch wheelbase and with an overall length of 154.7 inches, the Detroit e-tron concept is about 10 inches shorter than a TT.
Unlike the previous e-tron, which had one motor at each wheel, this latest concept has just two electric motors, each driving one of the rear wheels. Combined output is 204 hp and a claimed 1955 lb-ft of torque, although that latter figure is misleading because Audi multiplies the output through the drivetrain, as it did with the first e-tron. Figure something like 300 to 400 lb-ft in real life.
The two motors on this show car can operate independently, giving the car a pseudo torque-vectoring system that can make the most of available traction and enhance agility during aggressive driving. It also features a brake-by-wire system and, like the first e-tron, a special alternator that enables energy regeneration under braking.
The lithium-ion batteries—which weigh 880 pounds—are located just in front of the rear axle, and the car is said to weigh a total of 2976 pounds, or roughly 200 more than the similarly sized Tesla Roadster. Audi claims a 40/60 weight distribution and a 0-to-62-mph time of 5.9 seconds. Top speed is limited to 124 mph. By comparison, the Tesla is much quicker; we’ve clocked the Sport version to 60 mph in four seconds flat, although its top speed is 122 mph. The Detroit e-tron is said to have a cruising range of 155 miles on a full charge, which takes 11 hours with a 230-volt current or just two hours if you can manage to find a special 400-volt charging station
