Why is it that two cars, both with 3.5 liter engines get incredibly different horsepower. The Chevy Impala LS and the Lexus IS 350 for example both have the 3.5 V6 engine (the Lexus is slightly less efficient with 3 less MPG highway).
Obviously the vechicles way different weights, but HP is based on engine output.
I figure it all comes down to engineering, (I assume the IS doesn't come with a stock turbo). Naturally Lexus spent more money engineering, so why wouldn't chevy just put up the cost to do the engineering, and save more in the long run by having equally powerful cars for less?
I can't imagine it costing that much more money to make changes in the engine, for GM to decide against it. Even the base Grand Prix has a 3.8 liter, 200 HP engine, which is embarrasing compared to lexus.
I'm and advid fan of American brand vechicles, I hope there's a decent reason
