This is the 1:32 scale slot car raceway that employs digital technology to create the most realistic racing environment available. Unlike its analog predecessors, this set considers fuel consumption, braking responsiveness, and pit rules. Each of the three included cars is equipped with a digital microchip that allows you to change lanes or pull in to pit row--do so too fast, and your car may be penalized a lap. A display shows you how much "fuel" you have, and if you fill your car to its maximum, its top-speed will be slower to account for the "weight" of the fuel, but it will go farther. The track includes curves with reinforced barriers, three lane-switch areas, and a pit row area--over 20' of total track length. Cars include a Porsche 911 GT3, Chevrolet Corvette C6R, and an Aston Martin DBR9; all have working headlights and meticulously painted details. Ages 8 and up. Standard offset oval (configurable) 9 1/2' x 3 1/2'. (10 lbs.)
