Two iconic sports cars square off at the Consumer Reports test track - the Chevrolet Corvette and the Porsche 911. The engineers and technicians who did the testing talk about how each car performs at the track and they name their favorites. Since a new Corvette or 911 is out of reach for most of us, we also answer a reader question about affordable rear-wheel-drive sports cars.

Fuel efficient cars and their manufacturers are all in the news this week. Tesla announces that other car companies can use their patents, hoping to spur innovation in electric cars by mainstream manufacturers. Of course it winds up being a PR coup too. Ford's PR isn't as rosy as they announce errors in calculating fuel economy for their hybrids, leading to changes in the EPA numbers on their window stickers and goodwill payments to customers. We then answer some viewer questions about buying a good mid-sized family sedan that will go the distance, plus respond to a YouTube commenter who doesn't quite get the idea of a show called "Talking Cars."
