Cadillac STS

EPA MPG: 20 mpg

Road Test

This version of the STS's Direct Injection V6 and six-speed automatic transmission make for an impressive drivetrain. Changes over the years kept the STS a capable, smooth and elegant sedan. Still though, the interior is less meticulously trimmed and accommodating than the best in the class. Ride is comfortable and quiet, but rear seat room falls a bit short.
