The Petrobras-1 is Mariana Zanja's T-180. In Speed Racer (2008), the car appeared as one of the competitors of the Grand Prix. As a movie partnership between the Wachowskis and Petrobras, the Brazilian oil company determined that they wanted a car with the company's colors and logo to be featured in the movie.

Grand Prix

A green Type H car driven by Mariana Zanja and sponsored by Petrobras. Dons the #3. Mariana runs a great race. Despite starting in the midfield, she stays with the leaders throughout. She is first seen on the Drift Tower with the race leaders and she was in 4th place. Things only get better for Zanja as by the time she’s passed on the Tokyo Turn, she’s already occupying Third. She continues to chase down the two battling leaders throughout the Drift Towers, and when they both wipe out she takes 1st. She doesn’t stay in first for long as she’s later passed by Kakkoi Teppodama and Gray Ghost. She is last seen being passed on the Final Lap right before the final stretch. She was in 3rd when she got passed, but since two cars in front of her wrecked before the end, she usurped 2nd place overall.

Appearance
The car appears very similar to the Togokahn T-180 Hangul, with slight differences in the headlight form and the rear end being "blockier" in a way. The colors match with those of Petrobras.
