Why 6th gear

So here a six speed box helps. Modern cars may have two or more gears as overdrive gears i. Just over max power? Many engines make max power near the redline, I do not think an engine should be abused to its redline frequently. I would say keep the engine from just below max torque band start to the end of max torque band. For example, an engine making max torque from rpm, I would upshift around rpm, and downshift when the rpm falls below or so.

For a petrol engine which redlines at rpm, peak power is round rpm. There also if you let engine climb to rpm before upshifting, its not good.

Its always better to keep engine in max torque band, which is much lower than the point max power is produced. I am yet to see a torque curve which eases of near the max power ease of point. Max torque usually eases off much lower than the max power which is often near redline.

What you point out - a power band from i. Originally Posted by sgiitk. Last edited by ph03n! Originally Posted by swiftnfurious. What is power: Torque x rpm x a constant. The constant is irrelevant to the discussion.

So the peak power will invariably be at a higher rpm than the peak torque. Quite frankly the peak ttorque at as indicated by tsk is difficult to believe! I also think it should be more likely in the rpm area. Originally Posted by SS-Traveller. Not if you have a slow gearbox, and if you have to make an extra shift in the 6speeder.

Perhaps, but a manual gear box allows you to select a lower gear than usual, when you might want a sudden surge of grunt available. And my guess is that the auto box does not select the highest gear possible, so economy is reduced. And of course how do you perform an Italian tuning with an auto-gear box?
