Juechter has them at heart as he relates why stop-start systems aren't valued by Corvette customers: the "real environmental value is zero," he says, and it is perplexing why the "great-sounding engine" should be shut off at every stop. He's got a point, but the reality is that engines use fuel and create smog at idle. "Customers will have to put up with changes from what they traditionally expected in order to get better fuel economy," Juechter says.
Despite eschewing stop-start, the new Corvette's fuel economy reportedly increased by almost 12 percent over the 2013 model. A Stingray equipped with the seven-speed manual transmission is rated at 17 miles per gallon city and 29 highway, which are very good numbers for a sports car with a 6.2-liter V8 and 455 horsepower.
