If you want to go fast, shift at red line. You have to go back to Newton's law, F = ma, or a = F/m. Given the torque at the rear axel, F = T/r, where r is the radius of the tire. Torque is what provides the force to accelerate. Electric motors produce max torque at 0 RPM, unlike IC engines.
Wayne sure will report back, when DHL has shipped the parts back across the big pond and SF has scientifically examined the parts Till this happens we will keep the thread alive with the help of Isaac Newton. Best from Germany Martin
As I recall, shift point for max accel is at an rpm that will bring you to the max torque spot 'after' you shift into the next gear. For example, if max torque is @ 4000 rpm, you shift when the next gear lands @ 4000 rpm as you go through the gears. This way, you are able to take advantage of already being at the max torque spot in the power band at the next gear. HP is how high top speed in each gear versus the weight of the car and drag and all that that other stuff. To find max torque, put it in 4th, and maintain steady rpm , then WOT and see which rpm gives you the most accelaration. Those graphs are for selling cars, not for driving them.
I just shift when it seems like a good time to depending on how I'm driving. That technique has served me well. BTW, now that I am up in the 120K mileage, I very rarely if ever, exceed 6000 rpm. Occasionally, but not like I used to going back 20 years.
I spent the first ten something years signing up for every track event I could get into. I joined Porsche and even the local Corvette club just to get more track time and I didn't baby it out there. I think I used up any luck years ago so now it's just nice easy weekend car.
I've found that traffic lights have far more impact on my shifting times than torque charts. And though it can be thrilling, shifting through every gear @ 6500 on the way to Starbucks does seem a bit silly.
