Owned an LT Corvette Roadster
Owned an LT Corvette Roadster back in 92' that would approach 30 mpg on the Freeway. I believe it had a 6 speed with a button over- under-drive. Shouldn't be a problem with today's technology. However, I doubt that most Corvette enthusiasts purchase the car for the fuel economy. Keeping your foot off of the load pedal will dramatically increase average mpg under all driving conditions.
