1964 - 1968
Vanden Plas 4 Litre R (ADO 66)
It was felt by BMC management that a more prestigious car was needed to compete with the Jaguar MK X and Rover P5 3 Litre. A contract with Rolls Royce who was debating whether they should make a smaller car than the Silver Cloud/S-type became preferable. A venture was undertaken to put the Rolls Royce FB60 engine into a BMC Farina bodyshell. The engines origins dated back to the 1940s and were used in military vehicles. The rear end was restyled with a horizontal light arrangement and the roofline was raised to give more headroom at the rear. Automatic transmission and power steering were standard. The car was priced at just under £2,000, the tax-break limit on company cars. The car did not live up to pre-production publicity and it did not sell well and with the BMC merger with Jaguar in 1966 the Vanden Plas 4 litre R was doomed.
