Petrov Trunkov is a character in Cars 2.
Petrov is a greenish Zaporozhets car who is part of the Trunkov family that works with Professor Z.
"Petrov hails from a tiny village on the Baltic Sea where temperatures in winter drop down to a frigid -10C. And if that's not enough, the salty air and rocky roadways have irreversibly corroded his body panels. But Petrov really doesn't mind. In fact, he likes his engine air very cool, and thinks the bubbling rust makes him look more 'mileage mature'. Add the fact that he carries most of his weight in his rear-end and it's a wonder he doesn't break in half when the going gets rough."
Petrov wasn't clearly seen anywhere in the movie, but concept art shows a light green Trunkov, that appears to be Petrov, in the airport chase scene. However, the car in question doesn't appear in the final movie, and seem to have been replaced by Grem. There was also an airport playset released called the Cars 2 Spy Jet Escape playset which shows Grem and Petrov chasing Mater in the background, instead of Grem and Acer like in the movie. Interestingly, the set was released before the movie, as well as the die-cast for Petrov. It can also be noted that Petrov is included in the LEGO Cars 2 set 9483: Agent Mater's Escape as the operator of the Lemons' camera at Porto Corsa. This evidence suggests Petrov was originally meant to be a major henchman, similar to Acer and Grem.
- Petrov is modeled as a ZAZ-968 Zaporozhets with one adjustment: the letter T on his front bumper which stands for his last name; Trunkov.
- According to his Diecast and LEGO version, Petrov's license plate is 19-71 SMK. In the movie, during the fight in London, when Holley crashed two Pacers into two Trunkovs with her wings, the Trunkov on the right has that license plate. The one on the right has 70-21 SCB.
- The Geo Trax toy version of him shows his name as "Petrov Oilski" instead of Petrov Trunkov.
