Cadillac STS vs. BMW 550 Review

Utility
Neither the Cadillac nor the BMW 550 has a marked advantage when it comes to seating capacity.

Performance
With that kind of horsepower, both the Cadillac STS and the BMW 550 are genuine sportscars.

Dimensions
The Cadillac STS's tank is almost the same size as the BMW 550's, though the BMW 550's is slightly bigger. The BMW 550 and the STS compete for the same parking spaces.

Convenience
You won't have to visit your friendly gas station more often with the BMW 550 than with the STS, as both offer comparable ranges.

Cost
The BMW consumes a lot of gasoline compared to the Cadillac STS. In terms of fuel economy, the Cadillac STS has the BMW 550 beat. Regarding MSRP, the BMW 550 costs roughly as much as the STS (though the STS is a little cheaper).

Handling
With their similar turning radii, the Cadillac and the BMW 550 most certainly handle almost the same into and out of tight spots.

Drivetrain
The Cadillac STS's engine is substantially smaller than the BMW 550's. Keep in mind that smaller engines can be stressed more; however, smaller engines are often cheaper to fix. The STS could learn a lesson or two from the BMW 550 in terms of torque. The 550 packs quite a punch compared to the STS regarding torque, which is roughly equivalent to acceleration.

Comfort
While the front cabin in the BMW 550 offers a bit more head room than the Cadillac STS, there really isn't much of a difference. The ampler interior dimensions of the STS make it considerably more spacious for your passengers than the BMW 550.

Warranty
The BMW 550 and the Cadillac STS have the same basic after-sale protection.
