I have now had my spider (MT) for a few months and at 13,000 I feel it is fully broken in. I have noticed my best mpg is in 5th gear until 100km/h (62mph). Most non freeway roads only go up to 80km/h (50mph).
I have done a few tests comparing 5th and 6th gear and if my fuel economy (car reading not my own calculation) is 6.0L/100km going 85km/h in 6th gear. Dropping down to 5th would read 5.4L/100km. At 100km/h they would both be 6.0L/100km and at 120km/h I would get 6.2 in 6th and 6.8 in 5th. The difference between the gears is the same with and without cruise control.
I normally drive in 6th at speeds above 80km/h, out of habit more then anything as I have always assumed the lowest gear with enough power (which this car has in 6th by 80km/h in my opinion) is best for longevity of the engine.
All that said, given how I drive, I am very happy with the efficiency of this car and am more perplexed then anything. Has anyone else experienced this? At what cruising speed do other people make that last shift to 6th?
