The Chevy Autobots are featured in this official footage tied to the new Transformers film. Amongst the cars is a new Corvette Stingray concept never before seen.

Chevrolet unveiled footage of their vehicles which will play prominently in the upcoming Transformers: Revenge of the Fallen. The footage includes the release of a brand new Corvette concept. A total of five different Chevy models are featured in the 90-second video, as well as Optimus Prime, a truck, and a GMC pick-up. All of the vehicles shown are Autobots.

The Chevrolet Autobots used in the advert include a Corvette Stingray concept (Sideswipe), Chevy Beat (Skids), Chevy Trax (Mudflap), Chevy Volt (Jolt), and a new Chevy Camaro (Bumblebee). Optimus Prime is the Peterbilt 379 full-size truck, while the GMC Topkick seen in a few shots is the character Ironside.

Chevy's press release notes that these characters "will roll through the movie fighting Septicons -- other machines with evil intentions." Surely they meant "Decepticons" and not "Septicons." Fill in your own toilet/sewer joke here.

The new Corvette Stingray concept has been kept quiet for the last couple of years. This new concept is based on the first Stingray racer, unveiled in 1959. It has a split rear window, which many fans will be happy to see again. However, the company has no plans to bring such classic elements back to market. It was spotted at GM's design studio by Transformers director Michael Bay while he was touring the facility.

Other models will see the light of day. The Camaro comes out next month, and the Volt should show up next year. The Spark will debut as a 2012 model year. Transformers: Revenge of the Fallen debuts in Russia on 18 June, and Spain the day after. Most major markets, including the U.S. and U.K., will get the film a week later.
