Unlock this achievement by finishing 1st in
Backlot Battle with every vehicle, just as the description says. Remember it has to be
ranked to make the achievement pop.
Bear in mind that I unlocked every achievement I could in single player before jumping to the online multiplayer to get the last batch of achievements. You might need to unlock vehicles through single player before you can unlock this achievement.
- Thanks to Chris who made me aware of this.
- Madda has confirmed you do not need to unlock SP vehicles to get this, all cars are unlocked by default in online.To do your boosting a little more effective, you can go for these two achievements at the same time.
Just don't take turns winning, change vehicle between Battles and don't hit each other. The player who doesn't go for the achievements at present should hide in a corner and wait.

The inactive player COULD work on the Tornado achievement, but be very careful about it, because it could mess it up for both players if you ram each other in your struggles. I recommend you guys go for this in a separate Backlot Battle.

If there's more than three players in the game, one player can work on the Trooper, Untouchable and Soldier achievement, and the other players can go for these by ramming into each other and gaining small amounts of points;
