I'm convinced they took away the 6th gear in the manual solely so that it wouldn't be able to absolutely destroy the MPG numbers of the CVT Versa and the Sentra. Giving us an outdated 5 speed and stuffing a 4.xx final drive in forces us to turn more revs and burn more fuel. Still possible to beat CVT numbers with ease but if we had one more gear and a lower final drive this car would kiss 50 MPG on the highway with only the driver in it. I think part of the 4.xx final drive was also to make sure the 1.6 would have enough leverage to perform sufficiently with the car loaded to max capacity. Driving by myself it moves with ease but I can feel it when 3 big buddies hop in and suddenly the 1.6 is doing real work to get up to speed, wouldn't be able to use a 6th gear if it had one when 4-5 people are in my car.Cobb said:Kind of interesting to know why Nissan varied the engine displacement like that as well as the number of gears in the manual.
