Most of the manual 6 speeds have the same gear spread as the 5 speeds they replaced. All a person ends up doing is shifting more.
Spread means nothing. You could have the same "spread" as other cars...but if first gear is 10x as tall, the acceleration would be a dog. On the other hand, top gear fuel economy would be better.
With 6 speeds, they've tried to "best fit" better acceleration with improved fuel economy compared to the 5 speeds.
I mean the same first gear and top gear ratios as the 5 speeds they've replaced. The Honda Fit comes to mind. Actually, most Hondas come to mind.
Yep - the Fit is a joke in that respect. Now the Mazda 5 went from a 5 speed (and 2.3) to 6 speed (2.5) - but they had a lengthened 6th gear. It's relatively relaxed at highway speeds compared to the almost 3000rpm at 100kmh of the 5 speed.
Ideal gearbox for a standard commuter car you cruise easily at:
3rd - 35kmh
4th - 50kmh
5th - 65kmh
6th - 80kmh
Lightly loaded car, out on the plains etc, clearly that would be less. I find my Mazda will cruise 70kmh in 6 no problem, meaning it's still slightly too low. 6th should be a cruising gear, nothing else, not an accelerating gear.
So, if Subaru can maybe do a 6 speed the right way....
