Simply put, XO-1 is the fastest and most outrageous Ready-to-Race® RC car ever created. New aero improvements make XO-1 even easier to drive at the limit and more fun than ever before. If you’re looking for the most extreme RC thrill ride ever to hit the pavement, look no further than Traxxas, The Fastest Name in Radio Control®.

Traxxas XO-1 Supercar
Functional Aero

Stable Aerodynamics

From top to bottom, XO-1 is a masterwork of intelligent aero design. The sculpted supercar body slices through the wind for record-breaking speed. New high-downforce canards on the front splitter and a revised rear wing provide superior high-speed stability. A high-tech NACA duct under the chassis routes cool air around the motor with a rear body vent for hot air to escape.

100+ mph Top Speed

100+ mph Top Speed

The Traxxas XO-1 is a brutally fast hypercar intended for only the most experienced drivers. New aerodynamic improvements make XO-1’s performance more accessible than ever before with predictable straight-line performance and confidence-inspiring handling. Belted slick tires and a revised rear wing keep the XO-1 glued to the pavement whether you’re testing its top speed potential or carving up a tight race course.

Big Block Power

Big Block Power

XO-1’s legendary speed wouldn’t be possible without explosive power and XO-1 brings big-block 6s brushless horsepower to the table. Weighing almost two pounds, the massive Traxxas Big Block motor pumps out supercar speed and gut-wrenching torque for brutal acceleration. The finely-tuned Mamba Monster Extreme ESC delivers 25+ volts of ferocious power with scalpel-like precision.
