Tour Bus

The Tour Bus is a bus featured in Grand Theft Auto: London 1969, Grand Theft Auto: London 1961 and Grand Theft Auto V.

GTA London 1961 — GTA London 1969
The design of the bus is evidently based on that of the Double Decker (albeit slightly wider and shorter), which in turn is based on a Routemaster, but features an open top deck, complete with visible passengers on the seat. Like the Double Decker, the bus is also constantly painted red

Other its appearance, the Tour Bus' performance is the same as that of the Double Decker, being poorer than that of the Coach in GTA 1, but exactly the same as the Coach in GTA London 1969. Being the one of the heaviest vehicles in the game (the same weight as GTA 1 and GTA London 1969's Coaches and the Double Decker), the bus is predictably slow, with a very poor top speed but average acceleration. The bus also possess below average grip and handling, and average braking. Although game files reveal the bus has a lucrative base export value of £1,000, the Tour Bus cannot be exported due to its large size.

Grand Theft Auto V
The tour bus returns in Grand Theft Auto V, however, it's design is much different from it's 2D counterpart. The bus is based of the real life LA City Tours Bus. The front of the bus is the same as the Burrito. You can take sightseeing tours of Los Santos by walking up to the bus icon on the map.The bus shares it's design with the Rental Shuttle Bus, both buses are manufactured by Brute.
