28i optimum gear changes for performance

^the power won't be dropping off but the torque will which will mean it'll feel like it's not as punchy. It'll still be pulling hard up to the last few hundred rpm from the red line.
In general the lowest gear possible will give the best in-gear acceleration from any given speed.

It's not really. Fill in the white bits with accurate data (torque preferably at the wheels, gear ratios, tyre size & vehicle weight) & out pops speed & thrust for each gear. Plot it all on a graph & you can see what gear gives you the most acceleration at any speed. I took the graph out because google docs messed it up massively. Anyway you end up with something like this -Avallon said:thx
3rd at 50mph seems fastest initially but then the power seems to drop off - it's hard to say though as I don't tend to spend a lot of time overtaking
The spreadsheet looks quite scary!
Say you're accelerating from 100km/h (62mph), you could be in second gear but you'd almost immediately need to change into 3rd so you'll be better off to drop down to 3rd
Looking at that graph I've got gearing & crank output for a Z4 35i w/DCT 'box.
