11 Sec Electric Car

[MarauderMark]

I saw this and i thought its about time if we can get electirc cars this fast maybe time to slow down on gas , save money , save the envoirment..NOT!!:D Think this can be done to a Marauder if so how fast would it be?Still thought it to be cool for you all to see.

Geze...Talk about saving weight!

[TripleTransAm]

Wow, that's impressive. In 1992 we had severe traction problems on our hybrid Escort wagon (rear wheel drive) and we weren't putting out anywhere near the performance of this Mazda!

That's the beauty of electric motors: they put out their max torque at 0 RPM, because electric motor torque is directly proportional to current draw. Since the motors are not rotating, there is no reverse EMF to act as a 'resistance' so while the motor is at 0 RPM, it's pretty close to a short circuit. A nice hefty whallop without the time lost in winding up a torque converter! (and no need for a torque converter, since the electric motors don't need to keep running with the vehicle at a complete stop, and why would you want the momentary torque multiplication of around 2x at the stall speed when you'd get much much much more than that at 0 RPM?)

Downside: the more current draw through the motors, the bigger the batteries (or the shorter the charge lifespan).

One more thing about the wheelstand images... depending on where they put the batteries, this probably had a massive effect on the weight distribution of the car. Looks like they chose to put the motor(s) ahead of the transmission, so most likely they are lighter than the original motor, another contribution in reducing front end weight. (we put our motors on the rear wheels, but that was easier considering the Escort was FWD...it might not have been as easy to do with the Mazda). So the change in weight distribution, coupled with a 2 speed transmission (so you get some torque multiplication at the launch other than the 1:1 of a direct drive) plus the added multiplication of the 4.10 gears... true tire torture.
