Are you ready for the ultimate racing challenge? Take on a friend on the Multi-Challenge Race Track, but watch out -- if your car starts to run out of energy, you'll have to pull into the pits and recharge! It takes speed, skill and strategy to win on this track. Power slide around corners, then shift lanes and head into the pit. How long will you recharge, a few seconds or all the way to full power? Your call might decide the race! Build the track how you like and add jumps and other challenges along the way. It's LEGO racing action like you've never seen it before! Batteries required (not included).
