Hi all I haven't given completely up on getting a Crewman yet because of the apparent bad fuel economy. I drive highway a lot but also go up bush gravel road/tracks (not 4x4) rough gravel roads. I see the gear ratios appear to put the 6th gear slightly shorter (I think means more RPM) at cruise highway speed than a Commodore Wagon. 1st gear is very short, so again I assume this means 1st gear has very quick high revs and not much top speed? Manual Auto 1st 4.48 3.06 2nd 2.58 1.63 3rd 1.63 1.00 4th 1.19 0.70 5th 1.00 6th 0.75 Reverse 3.96 2.29 Final drive ratio 3.46:1 V6 3.08:1 V8 3.07:1 Had a thought about putting bigger rolling diameter tyres/wheels on to also get some lift. Plus having that as a thought, It made me wonder if this would help improve fuel consumption on the highway. by reducing the RPM at 100/110 kmh and allowing 1st gear to be more, like a normal 1st gear in most cars. Id no doubt have to use 5th gear more and use the 6th gear primarily for dead flat roads to prevent the engine from labouring. I did this in an old (don't laugh) 2.0 litre Camira manual. It worked a treat getting a bit extra clearance and I didn't notice any difference in fuel consumption. But it was a cheap car to run anyway. Though I do think if I did this in a Auto then the Crewman would perform very sluggish and use a lot more fuel. So hence the thought of manual 6 speed. More gears to play with. ps I don't carry much extra weight. I carry long skis/kayaks on the roof but they weigh bugger all. Anyone done this? Thoughts?
