"The drivetrain features the same 3.2-liter, three-valve sohc V6 found in the C-Class, the ML, the CLK and about a hundred thousand other Mercedes products. It’s a good, smooth, powerful workhorse of an engine that does many things well in many different cars. But because the Crossfire was put together in less than two years, there was no time—and who could justify the money—to design an engine specifically for it. Thus, the 3.2 falls just short of what you might expect in a sports car, but not too terribly short. It makes 215 horsepower at 5700 rpm and 229 lb-ft of torque at 3000 revs. That isn’t bad for a nice V6 but the Crossfire weighs 3060 pounds. Thus, the power-to-weight ratio also falls short of being sports car-ish, at 14.2 pounds per horse. A high-performance sports car should be down closer to 12 or even 10. "
