New Transformers Movie: The Autobots

The production staff made some changes on our favorite Autobots. All of them are now GM-branded vehicles except for Optimus Prime:
* Optimus Prime (Semi-trailer truck) - Orci described Optimus as a noble king, similar to King Arthur. His robot mode contains an arm cannon, and a retractable faceplate, similar to Optimus Primal from the Beast Wars series and the Transformers: Cybertron incarnation of Prime. His alternate mode, which has red flame artwork upon blue paint, is a close match to one of the Generation 2 Optimus Prime toys, and two versions were built. Lorenzo DiBonaventura said that Optimus is scaled to be 9.7m (32 feet) in robot form, and a semi in vehicle form. However, Michael Bay has said Optimus is 8.5m (28 feet) tall. A blue version of Optimus' head with motion capture points was used.
* Bumblebee (1974 Chevrolet Camaro, later reformatted as a 2008-2009 Chevrolet Camaro) - Bumblebee is the underdog character and a scout for the Autobots, as well as the Transformer most connected to humans. He ends up being purchased by Spike Witwicky, who is looking to buy his first car. His robot mode has been constructed as a physical prop in addition to a CG model. Bumblebee is 5.1m (17 feet) tall. Bumblebee's arsenal includes an arm cannon and shoulder missiles.
* Ironhide (GMC Topkick pickup truck) - Ironhide is one of Optimus' oldest friends, and has some cowboy characteristics, being the first in battle. While Ironhide was a van in G1, he was a truck in the Transformers: Robots in Disguise series from Japan. Ironhide will be 7.9m (26 feet) tall.
* Jazz (Pontiac Solstice) - Jazz is a "rock-and-roll" type character who lives by his credo of "If you can’t do something with style, it’s not worth doing at all."[35] He will be 4.6m (15 feet) tall. He has pronounced antennae on his head, and is either holding a gun in his left hand, or has a gun barrel in place of his left hand.[46] Another picture of him features fingers, although this may be art for the IDW comic adaptation of the film.
* Ratchet (Search & Rescue vehicle based on the Humvee design) - Ratchet's role in the movie is the familiar one of Autobot medic, and is 7.3m (24 feet) tall. His robot mode lacks the head fins seen in the traditional animated version of the character.
Meanwhile, quality GM-branded auto parts like Pontiac Parts are found at OEM stores online.
