Not only did Audi bring the R8 Spyder convertible to Frankfurt, they also introduced an electric-powered sports car called, for now, the Audi eTron. Unlike everyone's favorite movie about being sucked inside a video game, the eTron does not include Jeff Daniels in a futuristic body suit. It does include four electric motors, two per axle, to drive the wheels.
The eTron concept uses water-cooled lithium ion batteries to reduce weight and increase power, while aerodynamics, weight, and rolling resistance were engineered from the ground up to work with the new electronic system. The car also has something called "car to x communications," which allows the sensors and systems to interact with, say, traffic lights to determine the best driving strategy. That may be even more futuristic than Jeff Daniels' Tron suit.
The Audi eTron concept by the numbers:
- 313 hp (230 kW)
- 3300 lb-ft of torque
- 0-62 mph in 4.8 seconds
- 150-mile range
