Yeah, Corvettes get almost 30mph highway. Fail.
Many of the new V8s shut off half their cylinders at cruise speed to make sure the remain good on gas while your foot remains off the throttle. As for 4-cyls...you're right, fast 4-cyls are pushed so goddamn hard that they're not able to get "good" fuel economy...but I'm sure its not horrible either.
