Audi e-tron
Concept has four electric motors and a single battery pack

The world of electric and hybrid vehicles is progressing and growing at a rapid pace. While most people still think of hybrids and electric vehicles as low performance machines, there are an increasing number of high-performance electric vehicles being unveiled.

The first high performance EV was the Tesla Roadster with good performance thanks to the impressive torque of the electric motor. Audio has unveiled its latest concept car at the International Motor Show in Frankfurt called the Audi e-tron which just so happens to look like an electrified Audi R8.

The most impressive feature of the concept isn’t just its all-electric power train, but its tremendous amount of torque. Audi claims that the e-tron has a torque rating of  3,319.03 lb-ft. All that torque is generated by four individual electric motors situated at each wheel allowing the vehicle to be all-wheel drive.

The car has a total of 313 HP and promises to hit 60 mph in about 4.8 seconds. A more impressive number is that the car can go from about 37 mph to 74 mph in only 4.1 seconds. The all-electric range for the lithium-ion battery pack is 154 miles.

The EV is a large beast at 3,527 pounds and it measures in at 74.5-inches wide x 167.72-inches long and 48.43-inches tall with a wheelbase of 102.36-inches. The massive single battery pack alone weighs 1,036 pounds.

"We are trying to find a concept that requires no compromises," says Michael Dick, Member of the Board of Management of AUDI AG, Technical Development. "Electromobility means more to us than just electrifying conventional cars. Instead, we are dedicated to a holistic approach to all aspects of the topic."

Audi's American President called potential Volt buyers idiots not long ago and then quickly claimed he forgot what he said. There was only speculation surrounding the Audio EV concept at the time the comments were made.

Yeah I've had that with lugnuts before.

Still though, torque without motion accomplishes nothing.
Torque (SAE net): 295 lb-ft @ 0 rpm

I know that they always publish peak numbers but if the rotary force that pushes the car forward is not rotating then its pointless as far as I am aware. The millisecond that the torque of the motor overcomes the gravity of the car, which is kinda the point, then we're no longer at 0 revs.
Maybe the torque curve is rather flat and no one's bothered to tell me?

My point exactly. The peak torque of a prime mover is not the most important spec. The power output is.

Peak power, not peak torque, is what limits your 0-60 time (or more importantly, your 40-60 time.) It's what limits a car's speed, or sets how fast a truck can haul up a grade.

You can gear up or down to get more speed or torque, but no gearing in the world can give you more power than you started with.

You see it all the time in "sporty" economy cars. They have a short first gear to make the car feel peppy off the line, but they can't maintain acceleration because there's no power.

A little fractional horsepower winch can pull up a stump if you're patient and have enough gear reduction. But it won't push a golf cart up a hill at 5 mph.
