The Bentley Turbo RT Olympian: in 1998, London dealer Jack Barclay agreed to have a small number of cars built to incorporate many special features. These are probably the rarest version of the RT - although not officially recognised as such, therefore the RT Mulliner commands a much higher premium. These were sold as the Bentley Turbo RT Olympian. They can be identified by the five-spoke alloy wheels (borrowed from the 'Mulliner' version) and the "Olympian" boot badge. It is estimated that only four examples of this version were ever built. The Bentley Turbo RT Mulliner: The Mulliner version, available only by special order for the 1998 model year, was even more exclusive and expensive. It boasts a engine with a torque output of 634 lbft (861 Nm): this was achieved by developing a new compressor for the turbocharger, remapping the engine management system, and modifying the air intake system. Visually, Mulliners have more aerodynamic, rounded bumpers with prominent venting and often foglamps, as well as flared wings to accommodate the wider track and larger 18-inch alloy wheels, sitting on low-profile 255/55 tyres. Each car was built to individual specifications, with many sporting side and bonnet vents and also the smaller Mulliner rear windscreen. One popular feature in Mulliners is a prominent speedometer for the rear passengers. Just 56 Mulliner editions were built (all in 1998), of which 17 are right-hand drive. Seven of the Mulliner editions built are to standard wheelbase specifications, and 49 are on the lengthened wheelbase.
