Eric.
Yeah, so I think what I said still stands...I'm sure I have saw things elsewhere with max torque from 0rpm and then dropping sharply afterwards, whether exponentially or linearly I'm not sure.

Do you realize that the chart you gave showed precisely what ExigeEvan posted from Wikipedia?

I am not sure what your point is, unless you agree that an electric engine has more torque at a a higher peak for a much longer sustained time than an equivalent gasoline engine, because that is what the chart you posted shows.
 
But it drops off very suddenly. Hits a wall, so to speak, I think was his point.

also, how soon that "cutoff" happens depends on how heavy the load is and how steeply you're geared. Like I said earlier, you overload a diesel loco and you're creeping along at 10 MPH.

So does the gasoline car comparison line, only it does it much, much quicker than the electric.

It is why we shift gears.

The initial point was
semilife
Arent electric engines caplable of more tourque than any conventional mechanical engine?

Eric.
They make more torque, but only at a few RPM.

He has so far shown the opposite of what he initially said. But I am unsure if that is what was intended.
 
Foolkiller is on the same page as me, but Jim Prower if I post output charts for a 6 litre truck engine it doesn't prove my point on the curve of a 2-litre 4-cylinder.


Scale is one difference, and their designed use is another huge difference. My point still stands, and Eric., yours is still unfounded.
 
problem with that being that the electric motor could possibly run out of steam before a gasoline mill. Has happened with actual Steam. All things equal, a gas engine lugging from the line with a 1:1 ratio will slowly catch up to and eventually pass an electric with the same final drive.

Not that Electrics can't be geared to go blindingly fast, mind you (TGV hitting 300 MI/H) but that usually involves gearing UP. Most motors hit their work limit at around 3,000 RPM, and this is NOT the TORQUE PEAK. I don't know where Tesla's getting theirs. In fact, I'm almost willing to bet their test is under little or no load, and I dont' think the car is capable of speeds where the motor will hit 12,000 RPM unless it's geared down...and hits the Volt Peak Point earlier.

EDIT: Scale may be different, but designed use is the same: it's a traction motor. It's meant to get a load from point A to point B. And I if I think that Tesla's chart is contrived for their own purposes, I'm welcome to that.

With all that technical data. Do you guys think that having a racing series for electric cars backed by big corporate sponsors will advance the technology further, faster than if we left it up to R&D of the car manufacturers. I'm sure we can advance our way to recycling the batteries being used from all the EV race cars too.

It would start out with short races since the battery technology is not there yet but I think it can be exciting and interesting to watch at the same time. It will definitly help promote and advance EV's rapidly or do you think it's a waste of time since the dilema of the power drop off from electric motors? Isn't it possible to develop a transmission for the electric motor to aviod the power drop off.

If students of the International School of Design, ISD France can create a car like this, which is very fast, why is this Le Mans concept car slower in comparison?

Sorry but I can't take it seriously after this. "A concept with the image of a muscular sports car, the Audi TT." :lol:

I think the LMP is just far more realistic than a concept from some students.

Has been approved to race in 2012.
402bhp Hydrogen Fuel Cell holding 12kgs of Hydrogen.
 
Thanks for updating a two year old thread with a rendering and no source.
 
The current hybrid that raced LM couldn't finish and was in the pits all day long fixing electrical issues.
I think this car will follow similar.
