Man of Honour
I've just had another thought. I'm sure there's plenty of people on this forum who own modern cars with 6 speed gearboxes (hello BMW crew).
Can you tell me the lowest speed your car can comfortably cruise in in 6th gear, without struggling or getting crappy MPG.
I bet it's 55-60mph.
Indeed. It is on my car anyway. It'll do 50, or even 45 in 6th, so long as you're going down hill or very flat. It'll pull up hills from this speed in 6th, but it'll probably drink diesel.
60+ is my 6th gear speed.
