Chevy giving away 20 cars during Super Bowl

You could win a Chevrolet Corvette GS Convertible 4LT or one of the 19 other vehicles Chevy is giving away to viewers.

Chevrolet is giving away 20 cars and trucks--including Chevrolet Volt, Camaro 2SS, Silverado 150, and a bunch of Sonics and Cruzes--between now and the end of the big game. To win a car, players will need to download the Chevy Game Time app, complete the registration, and receive a unique "license plate." If your license plate is drawn before the game or in one of the Chevrolet ads shown during the Super Bowl or online post-game, you'll be a happy fan regardless of which team takes home the trophy.

But there's more to this sweepstakes than raffling off cars. By using the app to answer trivia questions during the game, you could win one of 14 vehicles. Questions range from polls on favorite foods to eat during the big game, to quizzes about commercials shown by Chevy or its partners. Each question you answer correctly is another chance to win a new ride.

Chevy has partnered with Bridgestone, Motorola, NFL, Papa John's Pizza, and SiriusXM Radio, and will be giving away thousands of other prizes using the Chevy Game Time app. The app is available for Android and iPhone, and anyone without a smartphone can visit Chevy's Game Time Web site to get a "Plate My Ride" ID to participate in the drawings and answer trivia questions.

A Camaro 2SS will be given away before the game, two winning license plates will be announced in commercials during the game, and two will be shown on YouTube ads the morning after the Super Bowl. Winners will also be notified by e-mail, so don't use a fake e-mail address when you register.
