NASCAR Silicon Motor Speedway was a sim racing attraction based on a full motion platform that was designed by LBE Technologies Inc. and licensed by NASCAR. It was introduced in September 1997 at the Mall of America in Bloomington, Minnesota. In March 2010, the final owner of the then-named Silicon Motor Speedway filed for bankruptcy.
History
Design and development
An idea of a simulated NASCAR experience happened when the sport was one of the fastest growing in popularity during the 1990s. The concept of the attraction was inspired by Planet Hollywood and Official All Star Café, with the idea of having celebrity endorsements to promote the experience.The final design comprised a network of multiple replica NASCAR stock car models at 75% scale positioned on a full motion hydraulic frames – which simulated acceleration, driving on banked curves and collisions – that were lined in front of three screens that displayed a 3D simulation provided by projectors, providing a 130-degree view for drivers. The 3D graphics provided in the simulation were supplied by 3dfx's 3D Blaster Voodoo 2. Drivers could also modify the performance of their cars prior to each race as well, including simulated adjustments to tire pressure, weight distribution and other changes. Inside the cars, multi-channel 3D audio was provided to occupants by Creative Labs' Sound Blaster sound card as part of the 3D Blaster Voodoo 2 system, while virtual video mirrors provided sideview and rearview visual guidance for drivers. For operation, regular-sized gas, brake and shift pedals were used with a four-speed simulated transmission and occupants were required to used seatbelts. The steering wheel also included an interactive feedback system.
Each simulator cost $70,000, the. NASCAR racers provided some technical assistance with the simulation experience and some, including Jeff Gordon, became shareholders in LBE Technologies Inc. As for the target demographic, LBE Technologies Inc. focused on adults, with customers needing to be at least 52 inches tall to enter the attraction.
