designated MP4/5B, Oatley and his team redesigned the front and rear wings, and reprofiled the rear bodywork around larger radiators, and several all-new venturi tunnels were put on the rear floor of the car. The engine was tweaked by Honda, and Senna did much development work to ensure he would have better reliability in the new season. He and Gerhard Berger took the fight to Prost and Ferrari in 1990, winning another six races and winning the Constructors' Championship. The McLaren proved to have an outright speed advantage in qualifying and was notable for the number of times both cars were on the front row. The car appeared to struggle slightly against the Ferrari 641s in the races themselves, particularly on heavy fuel loads with the Ferraris' race pace almost negating the McLarens' qualifying supremacy. It was in that year's race at the Japanese Grand Prix when Senna and Prost collided in the first corner of the first lap, giving Senna the championship due to Prost being unable to continue. Gordon Murray, the famed South African designer who had previously worked at Brabham since 1969, had designed championship-winning cars for the team and joined McLaren in 1987, retired from Formula One after his work on this car. He went to work on McLaren's road car project. There was a test mule during the 1990 season created by McLaren called MP4/5C for Honda's new V12 engine that was to be used by the Woking outfit for the following two seasons. This car, driven by the team's test driver Allan McNish, made its public on-track debut at a 3-day test session held at Silverstone the week before the 1990 French Grand Prix. While McNish did not push the car to its limits, the V12 impressed with its reliability at such an early stage of development. In popular culture Senna's MP4/5B was included in the 2001 video game Gran Turismo 3 under the alias "F090/S", but only in the Japanese and American versions. It was the least powerful F1 car in the game producing 700 PS (690 hp). It could be won by winning the Super Speedway endurance, the Grand Valley 300 km Endurance, the Dream Car Championship in Professional league, or by winning Formula GT. It is a random prize car in all four series. The McLaren MP4/5B was featured in the Codemasters video game F1 2019 as downloadable content for the
