"Scalextric ARC PRO; the first digital slot car race control system that allows users to wirelessly create and manage races through the use of a handheld smart device. Using Scalextric’s revolutionary new ARC Pro powerbase in conjunction with this app, users can seamlessly merge the excitement of real time, on-track racing, with the thrill of on-screen gameplay.
ARC PRO takes racing to the ultimate level with multi car racing up to 6 cars, lane changing, separate pit lane stop, KERS as well as variable weather conditions, tyre wear, fuel usage, brakes and post-race statistics.
This set is a hyper car show down featuring the McLaren 720S - the striking 4ltr twin turbo V8 star of the 2017 Geneva Motor Show, the Jaguar CX75 - speed, agility and low aggressive aerodynamics are perfectly combined and the Lamborghini Centenario - Lamborghini’s newest creation commemorating the 100th birthday of Ferruccio Lamborghini. Go head to head using revolutionary ARC PRO technology on multiple track layouts - the racing action has never been more real!"
