The one thing American "sports cars" get right in my book, the cruising gear. Seriously, Japan needs to learn. You only need to drop the ratio 10% on some of the stupider cars to get an almost normal cruising rpm.

i think most car manufactures beleive that we don't want to downshift. If we have 6 gears, there's nothing wrong with 5th for climbing grades, and 6th should be just for flat land/downhill

The Japanese speed limit is ~10% lower, 62mph. |

I tend to agree with this, although the smaller pistons, etc. usually need a higher rpm for best running and power, they don't need it for cruise. An overdrive gear would be very nice for our Texas flats. The really old (1959 Chevys, etc.) V8's ran at ~1,200 rpm at highway speed. |

Remember, back in the "old olde days" when axle ratios were commonly down around 2.73, 3.18, etc., not up at 3.87 (or higher) as is so common these days? Of course, those numbers were coupled with BIG V8 engines with lots of low-end torque, not SMALL I4 engines with anemic low-end torque.

Makes me remember when Volkswagen introduced a BlueMotion version for the Polo in the Brazilian market (with a flexfuel engine since the original Diesel ones couldn't be legally registered in this Republic of Bananas), and when it was reviewed in a local car magazine there was some criticism due to the need for more frequent downshifts
