Yet where it really matters, as a performance sedan, the CTS-V soundly spanks the M5. It's quicker in a straight line, handles better, steers better, even rides better (credit those amazing, multitalented magnetorheological shocks).
An all-new M5, rumored to develop 600-plus horsepower, is coming for 2011. Until then, though, it's the Cadillac CTS-V that best reflects the supersedan state of the art.
FIRST PLACE: Cadillac CTS-V
Glitzy exterior and cabin plus some finish issues detract from premium feel, but delivers where it counts. A Corvette ZR1 in four-door attire -- and a bargain to boot.
SECOND PLACE: BMW M5
Masterfully executed, but priced accordingly. Handling not on par with BMW's best, though, and V-10 power no match for Caddy's supercharged V-8.
