GM has always answered the call for more horsepower by trying to find ways to shoehorn bigger engines in their large cars and trucks. For some reason, this wasteful practice has made Americans happy, as long as the fuel prices were low. However, now that its pickup and SUV sales have been obscured by a new demand for fuel efficient cars, GM finally has decided that it might be a good idea to give Americans a 120-140 horsepower vehicle, that still gets over 40 mpg!
Why wasn't this vehicle developed when gas was $2.00 something a gallon, and had every indication that there was no end in sight? Heck, why hasn't this vehicle existed for years as an American car choice?
Because the technology didn't exist? Wrong. Consumers of foreign manufactured autos have enjoyed lightweight, fuel efficient, and fast sport compact cars for years. How do they do it?
Turbochargers: They have been in use for over 80 years. By forcing air into the engine, power output can be significantly raised, or fuel efficiency, or both.
Why are GM and other American car manufacturers only now giving conservation-minded Americans the option of cake + eat? Because our economy has never rewarded anyone, manufacturer or consumer, for making fuel efficient choices. The only check built into our economy is the cost of gas.
