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
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
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.
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.
quote: They still do but aren't exactly relative to internal combustion engines.
quote: RPM is RPM. Electric motors don't have some special RPM. Electric motors spin, combustion engines spin.
quote: Another thing to consider is this is using 4 motors, if the torque is total then divide by 4 and you get the torque at each wheel.
quote: I would say it's about 80% technical. they have special forums for off topic stuff (like politics) that I don't go to.
quote: There probably won't be an alternator/starter, fuel pump, separate brake system, transmission(?), driveshaft and maybe even no radiator/cooling loop.
quote: The motors are also pretty sophisticated
quote: Where did you get that 5252 number from? And what are its units?
quote: I can say that you do not calculate Electric motor numbers the same way as Internal Combustion motor numbers
quote: Peak torque could be at stall, in which case RPM = zero, and horsepower = zero.In fact, peak torque and peak horsepower rarely coincide. But that's an aside.
quote: Every electric motor I have seen makes peak torque at 0rpm.
quote: I dont understand how you can have torque which, AFAIK, is motion if nothing is moving.
quote: Still though, torque without motion accomplishes nothing.
quote: curve is totally different. Electric engines aren't like a gas engine when it comes to powerband - you have to think differently.
