The Steve Saleen-modified Tesla Model S has been on the news lately and it mentions that he modified the gear ratio to 11.39:1. The factory MS is 9.73:1. This means that the Saleen motor has to turn more to travel the same distance. I want to raise a question on this forum as to why would he do this. The torque is flat throughout, so it can't be because there's a sweeter spot at higher RPMs. It also uses more energy so it can't be beneficial to the range. The articles claim that the acceleration is faster, but to me it doesn't add up because the motor is the same power as stock and the power band is constant from zero until maybe ~10000+ where it starts to taper. Mechanical advantage would be better on the Saleen Tesla due to the higher leverage (torque) but that's the opposite of faster acceleration, unless he increased his overall wheel diameter by quiet a bit.
On a separate note, I don't like like what he's done to the styling. It's bordering on garish and to me the stock style is a perfect balance design by Franz von H. I do like Saleen's cooling improvement. What is it exactly that contributes to the heat build-up? Is it the due to the regen mostly? There could be an aftermarket for that but overall I am discounting the Saleen "improvements".
