Re: Mitsubishi Lancer Evo IX MIEV Concept - 268HP 1528TQ

could be, I just skimmed over the article looking for the word "range" so I could have missed that.
I don't think it directly stated it. But I'm guessing that they should have a direct link up with the wheels. If you put the motors in the wheels, you could use the magnetic junk being created by the movement of the motors to recharge the batteries (of course I'm only stating that would make the most sense, probably far from the cheapest way to go.)

kinda like mining trucks that use similar technology, though they have big-ass diesels to generate the electricity required for the motors.....

Yea. The man who popularized the electric motor/wheel combo was R.G. LeTourneau. LeTourneau Inc. makes the world's largest loaders, and they all use the electric motor in wheel combo. I went to the LeTourneau University, a school he founded to help train his factory workers, now its a full university. Pretty cool stuff, I've toured the factory. The scale of the equipment is just mind-boggling.

Contrary to the guy that wrote that article, 1528 lb-ft of torque is not as good as it may sound. This is torque applied directly at the wheels. It doesn't have the torque multiplying effect of a transmission. The Evo has a first gear ratio of 2.909 and the final drive is 4.529 for an overall ratio of 13.2. The gasoline Evo IX delivers 286 lb-ft maximum of torque at the flywheel, so in first gear it delivers a total of 13.2 x 289 = 3815 lb-ft to the wheels... way better than the electric, but only in 1st, 2nd and 3rd gear.

WOW, a top speed of 111mph

Unfortunately electric cars are just no there yet. This is a big step, but still know where close to where they need to be.

111 but i bet it goes 0-111 REAL fast

Pwew...

Got Unsprung Weight?
That would have to be a crapload of unsprung weight to void 1500lb/ft of torque though. Woulnd't it?
Unfortunately, no amount of horsepower or torque will counter the negative effects of unsprung weight.
Exactly what I was thinking. Unsprung weight is called that because it is weight that is at the wheels. Any time your wheels hit a bump, the amount of weight of the wheel is accelerated upward, then has to be accelerated back downward again. If this mass of the wheels/brakes/electric motor/etc is heavier and you are riding quickly over a bumpy road (Rally), the tires will spend more time being bounced then giving you the grip that you need.

The only people that think unsprung weight is good are hardtail harley riders and guys that ride custom choppers. I guess it's just easier to weld a bunch of tubes together and call it a sweet custom than it is to get an engineer and design a suspension.

I think the true value of a setup like this would be to use a 'traction computer' that a driver could tweak on the fly to give the car more grip exactly where he needs it. Having virtually instant max torque could also be very usefull in rally racing.

Good catch I was actually thinking the same thing I just didn't know if I was right.

But, if each wheel was doing 1500 lb-ft then it would be right on par if not a little better. But I doubt that it is.

Nice concept though.
