The company I work for has customers who do pretty fancy mechanical engineering. One of our customers adds their products (designed with our software) to Corvettes to make extra-powerful cars. They brought a couple of them over yesterday to show off. I’m more of a basic transportation, “my other car is a bicycle” guy than a car buff, but it was worth a look.
The red one is a production Corvette with Callaway tuning that gives it something over 500 horsepower and a top speed about 197 mph. The grey one is more of a concept car of which only 30 were made, with a few fewer horsepower than the other and a top speed more like 191 mph. However, the grey one has a manual transmission as opposed to the automatic that the red one has, which gives it a three-tenths second better 0-60 time.
