Autoblog put a 2011 Camaro SS Convertible through the paces and had these thoughts at the end of it all:
While the standard Camaro is no great pantheon of handling, the fact that its large, topless sibling can come close to matching pace is pretty impressive. Unfortunately, the convertible is lugging around a substantially larger curb weight, which colors the driving experience accordingly. According to GM, the Camaro SS Convertible tips the scales at 4,116 pounds in our tester’s spec. That’s a full 267 pounds heavier than the SS Coupe, with most of that weight lodged over the rear axle. As a result, acceleration feels somewhat dulled even though GM claims that the vehicle can get to 60 mph in 4.9 seconds – two-tenths of a seconds slower than the hard top. The convertible simply feels heavy to drive, with braking, cornering and straight-line grunt all taking a hit.
This isn’t particularly surprising when you think about it. The Camaro SS Coupe is known for two things – absurd amounts of power, and excessive weight. Droptops always pack on the pounds even more, due to the need for structural enhancements.
