Background
The list of cars that can claim to have been designed to accept a gas turbine is short, but the Rover P6 is on it. The British Rover car company was known for making dependable, conservatively styled cars for doctors and middle-aged professionals, but the Swinging Sixties clearly had an effect, and in 1963 Rover launched a sharp-suited clean-sheet design with futuristic styling and innovative features that immediately set it aside from its forbears.
Driven by a conviction that there was a gap in the market between smaller-engined cars and larger luxury saloons, Rover took a leap of faith and, perhaps buoyed by the success of their Jet 1 gas turbine powered prototype, single handedly created the executive car sector, albeit minus that jet engine.
Nonetheless the engine bay was designed with it in mind, and kept very wide as a result, so much so that the single overhead cam four-cylinder design that eventually powered the first cars looked rather lonely in the cavernous engine bay. The front suspension’s springs and dampers are operated by a bellcrank and sit horizontally, transmitting the car’s weight into the bulkhead, this keeping plenty of space for the gas turbine Rover hoped to fit at a later date.
This jet powered cars thing all sounds a bit fanciful these days, but Rover had invested a lot of time and money on the idea, and a full ten years prior to the P6 Geneva Motor Show debut had taken a Land Speed Record after achieving 152mph while running on the Jabbeke Highway in Belgium. The Solihull based company was convinced the pistons engine’s days were numbered and that this was the future.
In 1961 Rover built a T4 gas turbine powered prototype based on the P6 design concept which survives to this day in the British Motor Museum.
Four-wheel disc brakes (inboard at the back), de Dion rear suspension and exterior panels bolted to an inner monocoque shell are rather more conventional but still advanced for 1963, the latter being inspired by Citroën’s space-age looking DS of 1955.
The Rover P6 2000 won the inaugural European car of the Year award and gained further plaudits for passenger safety, having an interior designed with minimal protrusions to protect occupants in the instance of a crash. But sales in America were slower than Rover had hoped for, partially as a result of the car’s relative complexity but also because a lot of American car buyers simply viewed it as being deficient in the cylinder department, to the tune of four.
So, what better way to satisfy the trans-Atlantic demand for a more muscular powerplant than with one that started life with a Buick badge, the 3.5-litre Rover V8. This had emigrated from Detroit to the West Midlands in 1964, and first appeared with a Rover badge in the larger P5 Coupé, a car favoured by heads of state and royalty (both Margaret Thatcher and the Queen Mother were very fond of theirs).
If you really can’t have a jet engine then a V8 is probably the next best thing and thanks to that already wide engine bay, minimal modifications were necessary to create the Rover P6 3500. Not only that, with its unusual all alloy construction the V8 didn’t upset the car’s balance. A Borg Warner three-speed autobox was a popular choice, but for our money the all-synchro four-speed manual is the gearbox to have.
