1964 Vanden Plas Princess 4 Litre R

A brief encounter between Rolls-Royce and BMC led to the Vanden Plas 4-Litre R of 1964. The ‘R’ of the name was shorthand for the 3909cc Rolls-Royce six-cylinder engine under the bonnet of a modified 3-Litre bodyshell. The 175bhp of the all-alloy unit meant an easy car to drive – even without the extra refinement from the Borg Warner automatic transmission, power steering and servo-assisted front disc brakes. There was even more wood and leather inside than in the 3-Litre cars. Rolls-Royce even considered building its own version as a Bentley but then decided against it.
