Below is an overhead look at a modern high performance engine in cut-a-way form from the 2011 Detroit Auto Show – although this engine made its production debut in 2010. This engine’s roots trace back to the 1950s as it helped spawn the original high performance era in the United States but its time was short-lived. This new version is among one of the highest horsepower engines available in a standard production vehicle in the United States.

Should GM have had the Saturn SKY moved to Chevrolet with a different name?

Last year GM took a decision to discontinue Saturn brand. Yet, Saturn SKY was a great looking convertible car. I read a very interesting opinion in Facebook. Tracy Smith commented in General Motors' fan page saying "these Sky's were so cool GM should have moved this car over to Chevrolet and renamed it. Could have used this car as a tool to help people step up to a Corvette." What do you think? Should GM have renamed the Saturn Sky and introduced it into the Chevrolet line?
