Now this is our kind of Cadillac: It’s got a supercharged 640-hp 6.2-liter V-8, big Brembo brakes, an eight-speed automatic, and rear-wheel drive. A manual is not offered, but you won’t care when this brute hits 60 mph in 3.6 seconds and 100 mph just 3.9 seconds later. The steering is accurate yet hefty, while the ride is surprisingly civilized thanks to a magnetorheological suspension. Cadillac claims a top speed of 200 mph and we won’t argue. This is a supersedan in every sense.
