This is an interesting comparison test between the 2014 Chevrolet Corvette Stingray and the 2013 Porsche Cayman S. The new generation Porsche Cayman S (2013) is powered by a 3.4-litre boxer engine that develops 325 hp. With the PDK double-clutch transmission, the Cayman S is able to make the trip between zero and 62 mph (100 km/h) in 4.7 seconds. In contrast, the 2014 Corvette Stingray is powered by a much larger 6.2-liter V8 engine that's good for 450 hp. The 2014 Stingray with a 7-speed manual transmission is able to get from nought to 60 mph in less than 4 seconds.
