MINI Cooper S has 60% Power Advantage

In deliberating between a MINI Cooper and a MINI Cooper S, you might wonder just how much more power the S is really going to deliver. For acceleration, what counts is the torque delivered to the wheels given a particular engine RPM. I figure the sweet spot for every day motoring is in the 2,000-3,000 RPM range, where the S has an advantage that ranges from 70% at the low end to 60% at the high. This is what leads people to say they have to shift their S a lot less. When they find themselves at a lower RPM they can just hit the gas and accelerate up to a higher RPM and so more power.



Next, I need to do the same graph for each gear, expressed as power advantage over speed.
