Although the Cadillac brand lagged behind several years ago, it really is no longer the case! As proof, take the STS, a luxury sedan that is as comfortable as its road handling is exceptional. The basic versions are rear-wheel driven, while all-wheel drive is offered as an option. And if the 302 horsepower V6 and 320 horsepower V8 engines don't cut it for you, there is the STS-V, a very sporty Cadillac powered by a 469 horsepower V8 engine.
