Car Show Classic: 1970 Rover 3500 (P6) – Symphony In V8

IMG 20241103 120337 edited

Right before the catastrophic ‘70s laid waste to Britain’s automotive sector, there were plenty of superb UK-made designs throughout the ‘60s. The Triumph 2000, the Jaguar XJ6, the BMC ADO-16, the Rolls Silver Shadow, the Lotus Elan… And it could be argued that the absolute best one of them all was the Rover P6.

If you feel that my employ of the word “Symphony” is a tad over the top, I have to wonder whether you have misconceptions about the Rover P6 or about music. A symphony is a complex piece of orchestral music, something only attempted by the greatest composers. Similarly, Rover reached so kind of pinnacle of harmony and complexity with the P6. It’s in the same league as the Mercedes 600, the Lancia Flaminia or the Citroën DS, and it was definitely influenced by the latter. And then, they stuck a V8 in there for the Allegro (the symphonic movement, not the BL atrocity)…

P6 Advert

The P6 was originally slated to replace the lower-end of the venerable “Auntie” P4. When it was launched in 1963, it had a thoroughly modern 2-litre OHC 4-cyl., but Rover figured this new car was to be their mainstay for the foreseeable future, so they put just as much effort in the suspension and looks as they did the motor.

In terms of looks, the P6 was chiefly the work of David Bache. His avowed source of inspiration was the Citroën DS, especially from the cowl backwards. The front did not share the Citroën’s shark-like nose, however, but the end result was both elegant and distinctive. Right out the gate, the Rover impressed everyone who saw it, and conquered those who drove it. It’s no coincident that it won the first European COTY trophy in 1964.

Suspension-wise, Rover chief engineer Spen King opted for a De Dion tube rear axle, along with in-board brakes. On the other end was a completely novel IFS that, thankfully, CC’s Aaron Severson has discussed with his customary talent in this seminal post. This “bell and crank” contraption was devised to ensure that, should a new engine find its way under the bonnet, the suspension would not be in the way. In the early ‘60s, Rover still thought their pioneering work with gas turbine propulsion, but they were also actively working on a 6-cyl. solution, hewn from the OHC four, for a potential P7.

Rover V8

As luck would have it, General Motors decided to junk a perfectly good Buick small-block all-alloy V8. Rover heard about it and made an offer, which was accepted in January 1965. By 1967, the new 3.5 litre engine was tried out in the P5, which direly needed a shot of vitamins. The P6 was the next logical transplant recipient, in 1968.

The V8 was an ideal candidate for the P6. It weighed the same as the 4-cyl., only took a bit more space and provided about 40 extra hp, compared to the twin-carb 2-litre, that turned the Rover into a proper performer, snapping at the heels of BMW and Jaguar, and competitively-priced, too. Let’s take a look at the P6’s loyal opposition. To attempt an apples-to-apples approach, I tried to select automatics, as the P6 3500 had that transmission by default.

If you were in the UK circa 1970 and a couple thousand pounds were burning a hole in your pocket, the P6 was outstanding value for money. Only by spending £500-1000 more would you be able to find anything offering the same dynamic range. The Citroën did not yet exist with the dreaded Borg-Warner 35 that half of that table, including the P6, made use of.

One facet of the P6 that was perhaps on the lacklustre side was the interior. The dash was utterly dull, with an outdated horizontal speedo and not a very user-friendly layout. The front seats were very pleasant, but the rear ones were notably stingy on both headroom and legroom, particularly when compared to its foreign rivals. Rear boot space was also deemed below-par, due in part to the rear suspension taking up quite a bit of real estate.

At the end of 1970, Rover gave the P6 a facelift that chiefly affected the front end. They also introduced the 3500 S, which had a 4-speed manual and improved the car’s performance and fuel economy. The P6 carried on until 1977; pre-facelift cars like this one were still screwed together decently well, but by the last few years, the BL rot had set in and major quality control issues were harming its reputation.

Rover sold about 240k P6s with the 2.0 (and later 2.2) litre 4-cyl. between 1963 and 1977; the V8 models, sold between 1968 and 1977, tallied just over 80,000 units. Yes, they certainly made the P6 last, but people kept buying them. Even in the mid-‘70s, the car was still avant-garde technically – again, like the Citroën DS. Parallel lives, but the French car never did get the engine it deserved. Rover should have lent them their borrowed V8.
