Experience Hot Wheels® racing like never before with the most immersive racing set to date! Hot Wheels A.i. uses computer enhanced Artificial Intelligence to help guide your car around the track. But watch out! The A.i. also controls rival racers who will stop at nothing to overtake you and speed to victory. Use your driving skills and launch virtual hazards, like oil spills and tire blowouts, to be the ultimate Hot Wheels® champion! Or race off-track with the standalone freeplay mode. Now you can expand the Hot Wheels® A.i. Intelligent Race System Starter Kit (sold separately) with additional track pieces and a unique overpass that adds verticality to the race. Includes one track expansion kit. Each sold separately, subject to availability. Not for use with some Hot Wheels® sets. Colors and decorations may vary.
