2009 Cadillac STS vs. Its Competition

2009 Cadillac STS

With a choice of rear- or all-wheel drive and V-6 or V-8 engines, the 2009 Cadillac STS slots right alongside the mid-size luxury sedans from Germany and Japan, but it doesn’t have the presence or design detail of a BMW 5-Series or Mercedes E-Class inside.

The base V-6 STS has perkier performance than either the E350 or the BMW 528i, though the sweet turbocharged six in the new 535i may have it beat.

The E-Class more closely fits a definition of traditional luxury, with a classy appearance, while the 5-Series and M35/M45 feel sportier behind the wheel.

Yet another relatively new rival is the Jaguar XJ; with a standard V-8 engine and undeniable good looks, the XF starts at a lower price than the STS V-8.

The Infiniti M models have a surprisingly roomy interior—including a spacious backseat, which is somewhat hard to find in this class—but the ride isn't as settled, and road noise can be an issue.

And if you're especially green, you might want to consider the E320 Bluetec diesel; it doesn’t feel tremendously sporty, but it’s quick and returns standout highway fuel economy in the mid-30s.

Quick Specs
The 2009 Cadillac STS isn’t a standout for looks, but you’ll appreciate the way it drives.
The 2009 Jaguar XF is an easy car to love. It performs as well as anything in the class--and has unexpected glamorous touches that will win over converts.
The 2008 Audi A6 has plenty of competition, but its graceful look and feel set it apart from more brutal German and more clinical Japanese iron.
The 2008 BMW M5 has electrifying performance, but is saddled with an overdose of technology and a body in need of a few nips and tucks.
If you appreciate luxury and complex engineering solutions, then you'll love the 2008 Mercedes-Benz E-Class.
