SANTA MONICA, California — Last week Inside Line of the future Chevrolet Volt caught on the scene of the new Transformers 2 movie set, and GM officials were adamant that the Volt seen running with what could be the latest Autobots and Decepticons was not the Volt that will be coming to Chevrolet showrooms next year.Merely semantics, we'd say, as a source within GM has since confirmed what we suspected late last week; the Volt spotted on the streets of Long Beach, California was not a full running prototype, but a fiberglass replica of the production Volt design riding on a Malibu chassis with a full Malibu drivetrain and interior.Built by Saleen, the company that also crafted the Camaros for the original Transformers movie, the Volt was specifically built for Transformers 2. But unlike the Camaros where they built several cars, only one Volt movie car was constructed, and it was supposed to be held under very tight security.From 25 feet away, the distance of these spy photos, the Volt looks like a real car. However, like many movie replicas, the Volt is sporting everything from unique showcar paint to oversized brake discs made of cardboard.Set for production debut next summer, the Chevy Volt will be released at the same time Transformers 2 is hitting movie theaters, which is why GM benefits from the Volt's movie appearance, even if the electric car does not get a starring role. What this means to you: The Chevy Volt has become the poster child for the future of GM. And a couple of thousand movie posters can't hurt, either.— Kelly Toepke, News Editor
