> So are they saying that the power curve for the 911 engine peaks at much, much higher rpms? So high that you can fit two gear ratios between peak power and typical cruising rpms? That isn't how gearing works. Gearing allows car designers to tradeoff speed vs torque. You can design a gear so that when a car is running at 100 mph, the engine is at 800 rpm. I suspect Porsche has designed the 7th gear is for normal cruising (65 mph at 1000rpm), and the 8th is for autobahn cruising (165 mph at 1400-2000 rpm). |
