This is a Holiday Car.
If used during an XMAXX Event, you get 50% extra cash and XP from each race.
The Xmaxx Tree Racer is a car that could be obtained by completing the Oh Christmas Tree Car achievement, which required completing 400 races with a holiday car during the 2012, 2014, 2015, and 2016 Xmaxx Events.
- It is the first vehicle to use lifeforms in its design.
- It is based on the MP 427 by the front and back spoilers and its larger back wheels and smaller front wheels.
- In the beginning of the 2013 Xmaxx Event, Corndog stated that the XMaxx Tree Racer will never be re-released in a future event. However, this turned out to be false, as it was later re-released.
