To say the e-Tron car is insane is like saying Kayne West has no class.

WIRED: Audi says there’s still a lot of work to be done before EVs are ready for mass-market production. Until then, we’re dreaming of cars like the e-Tron.
Minimizing weight is the name of the game when building an EV because it extends range. The e-Tron weighs 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.

SHOOT: The EV Car industry bcan learn a lot from the builders of time trial bicycles. You need 2 things to the extreme: lightweight and aerodynamics. [Strength is non-negotiable].

Audi confirmed the worst-kept secret at the Frankfurt auto show when it unveiled the e-Tron, an electric concept car with four motors, grin-inducing acceleration and torque like an Abrams tank.

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 a staggering 3,319 pound-feet of torque.

That’s not a typo. We’ll pause for a moment to let you absorb that.

At this point the e-Tron is just a concept — and almost certainly a shot across the bow of Mercedes-Benz and its electric Gullwing.
