GM cars are Autobots and the Fords are Decepticons ...
Things are finally looking good once again!"While the yellow Camaro promises to be the eye-catcher in the movie, GM has three other prominent car characters in the film, making Transformers something of a GM coup for the big screen.
No one in the auto industry seemed to recall another movie where one automaker had so many vehicles playing major roles in one film. Remember, the Transformers in this movie are part and parcel of the story, not just used to cart actors around and provide background. And, in contrast with last year's Cars movie from Pixar, the major car characters are easily identifiable by make and model.
For example, in Transformers, Pontiac's Solstice has the role of Jazz, a gray hardtop 2-seat Autobot. Note that when the movie was in production, GM had only started selling the Solstice as a convertible. So, like the Camaro's Bumblebee, the Jazz Solstice is a car that still does not exist in showrooms.
Autobot Ratchet is played by a Hummer H2 that's modified to be a rescue vehicle. It's painted a fluorescent light green and has a winch and brush guard in front, shovels on its sides, and at least seven off-road lights on various light bars.
GM's other prominent character is Ironhide, played by a GMC TopKick pickup truck with Duramax diesel engine. The already tall truck is heavily modified with a winch, light bar and off-road, Extreme Terrain tires that are so large, they come to my waist when I stand next to them, and I'm 5 feet 4. "
