>>But it isn't rocket science, is it?...A top gear which is either sixth gear or fifth, with the same overall ratio will provide the same performance, economy or whatever.
That's the part I agree with ;-)
>>But a six-speed gearbox will require extra effort to get there
Why? I don't have to use the gears sequentially.
The top gear of 5 or 6 is normally an extra overdrive gear anyway, so you're really talking about the difference between 4 and 5 gears. 5 lower gears allows a lower first gear which might not matter to many, but I which appreciate when towing and starting on a hill - the CRV diesel has been produced with 5 and 6 speeds, first in the 5 speeder allows 46kph, in the 6 only 36kph, and I don't find it too short. 2nd is also about 20% lower.
I'd actually like 2 reverse gears - the one I have is too high to reverse a trailer without slipping the clutch.
Please yourself of course. BTW, many autos are now 6 or even 7 speeds too.
