With a small frame, MLX seats only a driver and one passenger. This vehicle has a highly modifiable chassis suspended on two independent suspension axles. Despite the claims of both vehicles' respective manufacturers, the MLX and Überchassis have similar capabilities, though the MLX is particularly renowned for its high speed and good suspension.
In its nearly forty-year production lifespan, the MLX has developed a fervent cult following. Factory-supported motorsport teams that utilized the MLX have routinely stood atop the podiums of several different 26th century sportscar racing series. The vehicle is extremely sought after by modern hot-rodders.
On Harvest in 2524, Felicia Sanderson's father pressured her into enlisting with the Colonial Military Authority after she stole an MLX and went out joyriding. MLXs were quite popular in the city of Mombasa on Earth in 2552.
Like the Überchassis, the MLX is seen in the Halo 2 campaign levels Outskirts and Metropolis. It is not accessible in-game, but can be destroyed with sufficient weapons fire, making it a possible hazard for units within the blast radius. As a civilian vehicle, the car is lightly armored. It only takes one M7 SMG magazine, or a grenade blast to completely destroy the vehicle.
