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.

When I take my car to the dyno, the sheet doesn't say I have 3000 lb-ft it says I have 220. Yet you guys are saying that a C5 actually puts down X 1000 lb-ft of torque to the road. If that is so, what does a Dynojet measure?


I think that the majority of people replying in this thread have little to no knowledge of how cars or dyno's work.

I'll do my best to answer your question:

When you dyno your car they make you put it in 4th gear to do the pull. They do this to get it as close to a 1:1 ratio through the tranny as possible. From the spark plug clamp they know what RPM your engine is turning, and the dyno computer already knows what RPM the drum is turning. It's all math from there. They aren't going to show you a 10x multiplication because your ratio is about 1:1 during the pull. In addition, even if you pulled it in 1st gear and you had a 10x gearing multiple, the dyno computer would divide it by some ratio between engine rpm and drum rpm.
