audi e-tron electric car: my haute heaven

Audi has just unveiled the e-Tron, an electric concept car with four motors, super acceleration and uber torque.

The German automaker set out to prove electric cars can rival the best sports cars, so it gave the all-wheel-drive two-seater 230 kilowatts (313 horsepower) and 3,319 pound-feet of torque. Um, SICK!!!!

To put that number in perspective, the Tesla Roadster, arguably the benchmark for production electric sports cars, produces 276 foot-pounds. The Dodge Viper gets 600 out of its huge V10. The Bugatti Veyron puts down 922. And the M1 Abrams tank produces 2,750 (at 3,000 RPM).

70 percent of this torque goes to the back 19" wheels. Audi claims the concept e-Tron will do zero to 100 km/hr (62 mph) in 4.8 seconds. It also will do 60 to 120 km/hr (37 mph to 75 mph) in 4.1 seconds. Top speed is electronically limited to 200 km/hr (124 mph) to maximize battery range.....or keep you alive.
Speaking of, the e-Tron gets its juice from a 42.4-kilowatt-hour, liquid-cooled lithium-ion battery with a range of 154 miles. Recharge time is six to eight hours at 230 volts. The pack weighs 1,036 pounds and powers four asynchronous wheel-mounted motors with a total output of 230 kilowatts. (For the sake of comparison, the Roadster’s 53 kw/hr pack weighs 1,000 pounds and its motor produces 185 kilowatts).

The e-Tron weighs a light 3,527 pounds. That’s just 253 pounds more than the new Ferrari 458 Italia. Audi made extensive use of aluminum and carbon fiber in building the car — which is slightly smaller in every dimension than the R8 — and made the doors, roof and other body panels of fiber-reinforced plastic. Audi says the car has a 42:58 weight distribution.

At this point the e-Tron is just a concept...... BOOOOOOO!!!!!!
Thank you for making my day Wired!
