Cadillac STS vs. BMW M5 Review

Cost
When it comes to gas mileage, the STS has the BMW M5 beat. Producing a precise fuel economy evaluation is so hard that some think not even the federal government can do it, but it looks as though the STS is the winner regarding fuel economy. As far as MSRP, the BMW M5 costs tremendously more than the Cadillac STS. The BMW M5 will cost you a lots_of_money in gasoline every year compared to the STS.

Utility
The BMW M5 and the Cadillac STS can accommodate the same number of passengers.

Convenience
You'll definitely have to take the BMW M5 for a fill-up more often than the Cadillac because of its tank size and fuel economy.

Comfort
While the front cabin in the BMW M5 offers a bit more head room than the Cadillac STS, there frankly isn't much of a difference. The ampler interior dimensions of the Cadillac STS make it significantly more spacious for your passengers than the BMW M5.

Dimensions
The BMW M5 is substantially heavier than the Cadillac STS. The Cadillac STS's tank is about the same size as the M5's, though the M5's is a bit bigger. The BMW M5 and the Cadillac compete for the same parking spaces.

Performance
With that kind of horsepower, both the BMW and the Cadillac STS are legitimate sportscars. In terms of horsepower, the BMW M5 packs quite a punch and will knock the Cadillac STS down a few rungs. However, note that high horsepower engines often command higher insurance premiums.

Handling
With its tighter turning radius, the Cadillac STS is most certainly sprier than the BMW M5, something to consider if you do a lot of city driving; however, keep in mind that a vehicle with a tight turning circle may feel a bit twitchy on the highway.

Drivetrain
The BMW M5 has a bigger engine than the STS. Keep in mind that smaller engines are often cheaper to fix, but a smaller engine usually has to work a little harder. Torque equals pickup, and the BMW M5 will have picked up and gone by the time the Cadillac STS finally gets moving. Torque is roughly equivalent to acceleration, and in this respect, the BMW M5 is substantially more powerful than the Cadillac STS.

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