2009 was a year of highs and lows for Corvette. The high was most definitely the introduction of the Corvette ZR1. With a supercharged 638 horsepower engine, it's the most powerful production Corvette ever built by GM. The new ZR1 garnered the attention of automotive journalists everywhere who showered the car with awards and accolades. When we talk about the low points, it's the global automotive recession that resulted in a 52% decline in sales from the 35,310 Corvettes built in 2008 to just 16,956 built in 2009.
