Or maybe right at the end of the straight you either have to over-rev the engine or upshift for just an instant before braking. ![]() Maybe second gear is too low and you have to shift right away into third, or perhaps that gear is too high and you don’t have enough torque. If you run the same course a lot, and your car is just the way you bought it, you’ve probably found that the gears don’t match the turn exits or the straights very well. The answer really varies a lot, depending on every individual’s specific needs and resources, from the casual amateur autocrosser to professional road racers-or from stock front-drive sedans with few gearing options to V8-powered racers with quick-change transmissions. For example, say a 7-year old asks, “Dad, where did I come from?” And after enduring a long, strained explanation about the birds and the bees, the child replies, “No, I mean what country!” Recently, a racer’s question regarding the selection of gear ratios led to this analysis of the engineering considerations. Sometimes the simplest, most innocuous question requires a complex and demanding explanation.
