When the Citroën DS debuted in 1955, it was indisputably the most advanced family sedan in the world. Naturally, the proud British auto industry was not about to take such a challenge lying down, but it took almost eight years to field a British contender: the remarkable Rover 2000. This week, we examine the history of the 1964-1977 Rover P6 from its abortive turbine engine to the calamity of the British Leyland merger and the V-8-powered Rover 3500.
If our American readers know the Rover name at all, it’s probably because of the Land Rover and Range Rover sport-utility vehicles, luxurious off-roaders that are the only remnants of the original Rover Company still sold in the U.S. The last Rover passenger cars sold here were the unsuccessful Sterling 825 and 827 of 1987-1990, which were related to the contemporary Acura Legend and Rover 800.
The Rover Company had a long history stretching back to the 1800s. In 1877, John Starley launched the Starley & Sutton Company, manufacturing tricycles, velocipedes, and “Penny Farthing” bicycles. Starley & Sutton’s Rover Safety Bicycle, launched in 1884, is generally considered the prototype of the modern bicycle. Based on its success, Starley went public in 1896, changing the name of the company to Rover Cycle Co. Ltd. Rover moved into motorcycle production in 1902 and automobiles in 1904. The firm was named Rover Motor Co. Ltd. in 1906, although until the 1920s most of its business was still in bicycles.
Rover’s fortunes waned in the 1920s until the arrival in 1929 of new general manager Spencer Wilks, formerly of Hillman. Wilks — joined the following year by his brother Maurice, who became chief engineer — decided to take the company up-market. By the start of World War II, the Wilks Brothers had established Rover as a thoroughly respectable but somewhat stodgy middle-class brand, staunchly conservative in both styling and engineering.
Behind the scenes, Rover had grander designs. During the war, Rover had been a contractor for Frank Whittle’s Power Jets Ltd., developing the “Whittle Unit” gas turbine that became the basis of Britain’s first jet engines. Although Rover transferred the work to Rolls-Royce in late 1942, after the war ended Rover hired several former Rolls gas turbine engineers, including Frank Bell and Charles Spencer (“Spen”) King. Frank Bell proposed adapting the gas turbine for automotive use, leading to an enthusiastic, highly secretive development program. By 1947, Bell and King had completed the first running prototype and by 1950 had unveiled the world’s first turbine-powered car: the JET 1.
The gas turbine was one of the great unfulfilled dreams of the fifties and sixties. Smooth, simple, and offering a better power-to-weight ratio than most piston engines, the turbine soon came to dominate the aviation world and many saw it as the automotive powerplant of the future. Unfortunately, gas turbines were badly handicapped for passenger car use by their high fuel consumption, poor throttle response, high exhaust temperatures, and the cost of machining suitable turbine blades.
Nevertheless, Spen King, Gordon Bashford, and Peter Wilks kept working on the Rover turbine program throughout the 1950s. In 1956, they developed the T3, the first car specifically designed around a gas turbine engine. Aside from the turbine, the T3 had a variety of other advanced features, including unibody construction with fiberglass body panels, a De Dion rear suspension (previously installed on the Rover Special one-off race car in 1949), and four-wheel disc brakes. The T3’s performance was greatly improved from earlier turbine prototypes, but its fuel consumption — less than 10 mpg (23.5 L/100 km) — was still unacceptably high.
THE ROVER P6 TAKES SHAPE
The Wilks Brothers realized that the turbine was far from ready, but many other aspects of the T3 were very promising. In 1957, they approved the development of a new midsize model, the P6, which would replace the popular P4 series and use many of the concepts from the T3. Since the engineers were still hopeful that the turbine program would bear fruit, the P6 was to be designed to accommodate either a conventional engine or a turbine.
While Bashford, King, and Peter Wilks worked on refining the T3’s advanced engineering, styling director David Bache and his team set to work on the exterior design. Possibly inspired by a number of one-offs by the Italian designer Giovanni Michelotti and possessing proportions mildly reminiscent of the Lancia Flaminia Berlina, the Rover P6 emerged as crisp, slightly rakish four-door sedan with styling that foreshadowed the angular Giugiaro designs so popular in the 1970s. Initially, the P6 was to have a sloping nose with somewhat awkward exposed headlights, but after seeing the initial prototypes in early 1959, the sales department registered strenuous objections, leading to the adoption of a less aerodynamic blunt nose with quad headlights set into a full-width grille.
One of the minor goals of the P6’s “base frame” construction — like the Citroën DS, it had a steel monocoque with unstressed, bolt-on exterior panels — was to make it cheaper and easier to restyle. Ironically, the P6’s styling would be almost unchanged throughout a 14-year lifespan, but even at the end of its run, it still looked surprisingly contemporary for a car designed in the late 1950s.
In 1961, Rover unveiled its latest turbine prototype, the T4. This now had front-wheel drive and Rover’s latest 2S160 regenerative turbine, making 140 shaft horsepower (104 kW). The T4 had impressive performance, but fuel economy remained sub-par: Rover quoted 20 miles per Imperial gallon (16.7 mpg U.S.; 14.2 L/100 km), which was probably optimistic. The T4 proved to be the end of the line for Rover’s passenger-car turbine, although development of truck and marine engines continued until the end of the decade and turbine-powered Rover-BRM race cars ran at Le Mans in 1963 and 1965.
What was ultimately more significant about the T4 was that its body was a prototype of the Rover P6, albeit with an extended, more streamlined front clip designed by Spen King. The T4 had FWD, of course, while the P6 was rear-drive and had a different rear suspension, but much of the T4’s structure was the same as the conventionally powered P6 that debuted two years later.
A MODEL MODERN MOTOR
Even without a turbine engine, the production Rover P6 was a highly sophisticated car with notable advances in almost every area. Occupant safety was a high priority, a rarity in that era except at Mercedes-Benz: The monocoque base unit was intended to provide a rigid safety cage for the passenger compartment and Mercedes-style impact-absorbing crumple zones were provided both front and rear. In a severe frontal impact, the firewall was designed to deflect the engine downward, preventing it from being forced into the cabin. All these things are standard practice for modern cars, but were almost unheard of at the time. Inside, the dash and interior were thoroughly padded and shoulder harnesses and inertia reels were standard equipment.
The P6 had a peculiar front suspension, designed by Gordon Bashford to accommodate the bulky turbine engine. The suspension used horizontally mounted coil springs, acting against the cowl structure rather than the fenders or front crossmember. Each steering knuckle was carried on a stout tubular strut, which was connected to the lower wishbone via a ball joint. The upper ball joint was mounted atop the strut, as in a MacPherson strut suspension, allowing the strut to pivot with the front wheels. The top of each strut was also connected to a pushrod that transmitted wheel motion to the spring and the upper wishbone, which was turned sideways and pivoted on the cowl. Tubular shock absorbers were mounted vertically behind the struts and ahead of the upper wishbones, which were connected by an anti-roll bar. The principal advantage of this unusual arrangement was that it maximized the width of the engine bay by eliminating the need for shock towers.
The rear suspension was another cause célèbre of this era, the De Dion axle. Named for the Marquis Albert de Dion, whose company patented it in the 1880s (although it was actually invented by Charles-Armand Trépardoux), the De Dion is a compromise between the independent rear suspension (IRS) and the live axle. As with IRS, a De Dion suspension’s differential is fixed to the body and thus is not part of the vehicle’s unsprung weight, improving ride quality. Unlike IRS, the rear wheels are connected with a U-shaped beam (the De Dion tube) that forces them to maintain a constant camber, which prevents the wheels to respond individually to bumps, but reduces the tail-happiness to which swing-axle or semi-trailing arm independent suspensions are prone.
In the Rover P6, the De Dion tube was located by trailing arms (which also served to transmit braking and acceleration forces to the body), upper leading links, and a lateral control arm. Although De Dion suspensions don’t allow camber changes, the rear track does change slightly as the wheels move through their travel. Some vehicles accommodate these changes by using sliding driveshaft splines, which is less than ideal because the splines can bind under power; to avoid that problem, the Rover’s De Dion tube used a telescoping center section, allowing the tube itself to change its width slightly.
The P6 had Dunlop disc brakes at all four wheels and the rear brakes were mounted inboard, further reducing unsprung weight. Unfortunately, the consequence was that the rear brakes were more cumbersome to service than outboard brakes and in hard use, the brakes and differential could cook one another to their mutual detriment.
Such foibles notwithstanding, the net result of this arrangement was fine handling, excellent stopping power, and a very good ride, marred only by certain slight but disconcerting pitching motions under certain road conditions. In overall road manners, the Rover P6 was one of the most capable sedans of its era.
SIX BY FOUR
Although the gas turbine never made it to production, the Rover P6 did have a completely new engine, a 1,978 cc (121 cu. in.) overhead-cam four with an iron block and an aluminum head with an integral intake manifold (much like some postwar Nash engines). The four used a Heron head, with the combustion chambers formed by the tops of the pistons rather than in the cylinder head itself. Heron heads, which were common on motorcycle engines and were later used by Ford for its Kent cross-flow fours, allow an engine to be shorter, stiffer, and lighter while improving gas flow for better low-end torque and fuel economy than conventional combustion chambers. With a single carburetor, the 1,978 cc engine made a reasonable 100 gross horsepower (89 hp DIN, 66 kW), albeit with more noise and vibration than Rover customers were used to enduring.
With a new four-speed manual transmission, the single-carb engine could push the 2,800-pound (1,270 kg) Rover P6 from 0-60 mph (0-97 km/h) in less than 15 seconds, with a top speed of 104 mph (166 km/h). That was far from blazing performance, but it was certainly adequate and competitive with many of the Rover’s contemporary rivals.
A NEW MARKET
Impressive as it was, the Rover P6 caused much consternation within the company. The new model was a considerable departure from Rover’s traditional quiet conservatism, which had made the bigger 3-Litre (Rover P5) the car of choice among British government officials. The P6, by contrast, had a more raffish aura, closer to a Jaguar than a traditional Rover. That was partly by design, but it was not an uncontroversial decision.
The Rover marketing department was very uneasy about the P6, particularly its four-cylinder engine. Even the company’s suppliers were not sold on the basic concept and many Rover execs feared the P6 would cheapen Rover’s image. The object of the new model, of course, was to increase the company’s volume and reach out to younger buyers who would not otherwise have considered a Rover. Both the Rover P4 and P5 sold in modest numbers and total annual sales in the early sixties hovered around 12,000 units, but the P6 was planned for much larger volumes, with a production capacity of 500 or more cars a day.
CAR OF THE YEAR: THE ROVER 2000
Although the T4 prototype had been shown in 1961, production delays meant that the Rover P6 didn’t make its formal debut until the Earls Court show in October 1963, two years later than originally planned. Dubbed Rover 2000, the new car made quite a splash, particularly among patriotic British journalists. It won the first European Car of the Year award, beating out the formidable Mercedes 600. Critics universally praised the Rover’s ride, handling, brakes, and safety features.
Fears that the Rover 2000 would be a commercial flop were soon allayed. With a starting price of £1,264 9s 7d with purchase tax (about $3,500), it was more expensive than any Vauxhall or Ford, but a good deal less than a Citroën DS or Jaguar Mark 2. The 2000 was also far more obtainable than its 3-Litre brother, which cost some £600 (nearly $1,700) more. The 2000’s only direct rival was the new Triumph 2000, introduced at about the same time. The Triumph was marginally less sophisticated than the Rover, with rear drum brakes and semi-trailing arm independent rear suspension, but had a smooth 1,998 cc (122 cu. in.) inline six and optional overdrive, which allowed more relaxed cruising than its Rover counterpart.
Together, the Rover and Triumph carved out a market in the U.K. for what we would now call near-luxury sedans. Between the two of them, the two 2000s claimed about 90% of the 2-liter saloon market. The Triumph sold better than the Rover, thanks in part to a lower price — a Triumph 2000 with overdrive cost about £110 less than the Rover — but the P6 boosted Rover’s 1964 sales to nearly double those of 1963 and there were lengthy waiting lists. By 1966, Rover was selling nearly four times as many cars as they had at the beginning of the decade.
THE COLONIES DEMUR
The Rover 2000 had far less impact in the U.S. than in Great Britain. It was not from any lack of critical approval; the American press was as enthusiastic as their UK counterparts were, Road Test declaring the Rover P6 the best European sedan in its class. Still, by American standards, $4,000 was a lot to ask for a compact sedan with an underpowered four-cylinder engine and a manual transmission. An automatic option didn’t appear until 1967 and it had an unfortunate effect on both acceleration and fuel consumption.
The addition of the more powerful 2000TC (of which more shortly) in early 1966 helped somewhat, but U.S. sales remained sluggish, never topping 3,000 units a year. The Triumph 2000 fared no better — American buyers appreciated British sports cars, but modest-size European sedans had yet to find their niche. Worse, the P6s that did sell in the U.S. made a poor impression on buyers. A 1970 Road & Track survey of Rover 2000 owners reported a litany of complaints ranging from premature clutch and tire failure to oil leaks and overheating.
Interestingly, in the U.K., the P6 was generally considered a reliable car, albeit not without its trouble spots, including the brakes (particularly the original Dunlop units, replaced in mid-1966 by a Girling system), differential oil leaks, and a propensity for corrosion of the monocoque base structure. However, the U.S. cars were admittedly handicapped by more demanding American driving habits and the different expectations of American buyers regarding routine service. The Rover 2000 was not easy to work on (valve adjustments, for example, required removing the cylinder head and the inboard rear brake pads could only really be accessed from below), which translated into higher repair costs.
Compounding the problem was the spotty availability of parts and qualified technicians. Rover’s U.S. organization, then headed by J. Bruce McWilliams, came up with clever promotions, but putting Rover on the map in America would have required the factory to make a much bigger investment. In 1967, Rover’s North American organization merged with Triumph’s following Rover’s acquisition by Leyland Motors, which owned Standard-Triumph. After that, the slow-selling sedans took a back seat to the more popular Triumph sports cars. Rover finally withdrew from America entirely in 1971, save for Land Rover, which lingered until 1974 and would return later.
ROVER 2000TC AND BENT EIGHT
The Rover 2000 was a comfortable car with fine road manners, but its straight-line performance lacked the verve of bigger-engined Jaguars. To answer the demand for more power, Rover contemplated offering bigger derivatives of the P6’s four-cylinder engine: a 2,472 cc (151 cu. in.) five and a 2,967 cc (181 cu. in.) six, both created by simply adding extra cylinders to the four.
The five was abandoned when the Rover engine department determined that they could nearly match its output by giving the four a new cylinder head with a higher compression ratio, new intake and exhaust manifolds, and a pair of bigger S.U. HD8 carburetors. The result was 124 gross horsepower (114 hp DIN, 84 kW), enough to trim 0-60 mph (0-97 km/h) times to around 11 seconds and boost top speed to a claimed 112 mph (180 km/h) while still returning respectable fuel economy. The twin-carburetor car, known as the Rover 2000TC, was introduced at the 1966 Geneva show and offered first in Europe with the same 9.0 compression ratio as the standard engine and 107 hp DIN (79 kW). The more powerful high-compression British and American versions followed later in the year.
The six, which required a longer, restyled nose, would have provided more power still while answering the sales staff’s persistent fears that the four lacked the smoothness and refinement Rover buyers expected. The six would probably also have offered much better performance with the Borg-Warner 35 three-speed automatic that became optional on single-carburetor four-cylinder cars in late 1966.
The six-cylinder car was known internally as the P7 and had it made production would probably have been called the Rover 3000. However, the P7 was canceled in late 1964 because Rover managing director William Martin-Hurst — who had succeeded Spencer Wilks in 1962 — had found an entirely different solution.
During a 1964 trip to pitch the Rover turbine engine to the American outboard motor manufacturer Mercury Marine, Martin-Hurst had come upon an example of Buick’s recently abandoned 3,528 cc (215 cu. in.) aluminum V-8. He soon discovered that the V-8 was very nearly the same length size as the Rover 2000’s four-cylinder engine and, thanks to the Buick’s aluminum construction, weighed only 12 pounds (5.5 kg) more. Martin-Hurst arranged to buy the engine and ship it back to Rover’s Solihull factory, where he persuaded engineer Peter Wilks to install the V-8 in a 2000 sedan. The Buick engine’s power and torque provided impressive performance and the aluminum V-8 did not change the 2000’s weight distribution in the way the six-cylinder prototypes did.
Martin-Hurst eventually secured the manufacturing rights to the Buick engine and enlisted the services of retiring Buick engineer Joe Turlay, the aluminum V-8’s lead designer, as a technical adviser. (More details about the origins of the aluminum V-8 can be found in our article on the Buick Skylark.) While the basic design had to be revised in a number of significant ways to suit Rover’s needs and British manufacturing capabilities, including a switch from semi-permanent steel molds to sand-casting, those modifications did not alter the engine’s obvious virtues.
The V-8 found its way into the Rover P5 in 1967 and was installed in the P6 the following year. Doing so was not a universally popular idea — Spen King, for one, strongly opposed the idea of buying an outside engine — but the V-8’s effects on performance were too dramatic to ignore. Despite a larger radiator and other changes, the V-8-powered Rover P6B (B for Buick) was only about 35 pounds (16 kg) heavier than the four-cylinder 2000 and shifting the battery to the boot actually fractionally improved weight distribution. Fitted with two S.U. carburetors, the 3500 engine was rated at 184 gross horsepower (146 hp net, 109 kW), substantially more than even the 2000TC.
The Rover Three Thousand Five, as it was pronounced, was expensive, bowing at £1,791 with purchase tax (around $5,000), but the added muscle was well worth the premium. Despite compulsory automatic transmission and a taller axle ratio, the 3500 was more than a second quicker to 60 mph than a manual-shift 2000TC and fully 6 seconds quicker than a single-carb automatic 2000.
The 3500 would have been quicker still with a different transmission. The Borg-Warner 35 was initially mandatory because the 2000’s four-speed gearbox couldn’t withstand the V-8’s torque, but the automatic made the powerful engine feel unaccountably sedate. A 3500S manual with a beefed-up four-speed (not to be confused with the poor-selling and short-lived U.S. V-8 car, which was also badged 3500S) was added in the fall of 1971. The manual transmission and a revised exhaust system providing slightly more power (not reflected in the official specifications) made the 3500S by far the fastest P6 model, capable of 123 mph (197 km/h) all out.
THE BIRTH OF BRITISH LEYLAND
In 1967, Rover was bought out by the Leyland Motor Corporation, which had acquired Standard-Triumph earlier in the decade. The following year, Leyland — with no small encouragement from Harold Wilson’s Labour government — merged British Motor Holdings, which included BMC (Austin, Morris, MG, and Riley) and Jaguar as well as various automotive suppliers. The result was British Leyland, an enormous, unwieldy conglomerate of more than 100 different car, truck, and bus manufacturers and suppliers.
Although LMC chairman Donald Stokes received a peerage for his efforts in the birth of British Leyland, the results were chaos. British Leyland now included nearly every automaker in the UK. Companies that had previously been arch-rivals were now siblings; what had been healthy competition abruptly became cannibalism. While Lord Stokes played the confident captain of industry in the press, the scope of his new empire would have daunted the most gifted executive and its problems were sobering.
For a time, things at Rover proceeded apace, but Lord Stokes soon began to order rationalizations and cutbacks throughout British Leyland. The planned successor for the Rover P5, the P8, was canceled in 1971 on the grounds that it would compete with Jaguar’s XJ6, even though Rover had already invested around £5 million (around $12 million) in the project. Rover and Triumph were ordered to develop a joint replacement for the Rover P6 and Triumph 2000/2500 (which became the Rover SD1) and combined into a short-lived Specialty Division.
In the meantime, the Rover 2000 and 3500 got a minor facelift for the 1971 model year, featuring a rather ugly black eggcrate grille, a new bonnet, and, for V-8 and twin-carburetor cars, an updated instrument panel. Four-cylinder cars also got boot-mounted batteries to match the 3500. In 1973, the four-cylinder engine was bored out to 2,205 cc (134 cu. in.), increasing the output of the single-carburetor engine from 89 to 98 hp DIN (66 to 72 kW) and from 108 to 126 lb-ft (146 to 170 lb-ft) of torque. The bigger engine also brought a new name: Rover 2200SC. The dual-carburetor version, badged 2200TC, now had 115 hp (85 kW) and 136 lb-ft (184 N-m) of torque. Both four-cylinder models adopted the V-8’s rear suspension, which had stiffer springs and a slightly lower ride height.
In other respects, the P6 was little changed. While the styling still looked sharp and the engineering was far from dated, the car’s minor foibles had become harder to overlook as the competition improved. Moreover, reliability and build quality declined markedly, doing serious damage to Rover’s reputation.
Rover P6 production continued through 1976 and the 2200 remained on sale through the 1977 model year. Total production was something on the order of 330,000 units, including a small number of CKD (complete knocked down) cars for overseas markets. (The final car off the line was identified as No. 327,308, but that figure was almost certainly incorrect.)
The P6’s replacement, the Rover SD1, was an impressive car in many respects, but — at least on paper — represented a technological step backward, with its live axle and rear drum brakes. Alas, the SD1 was even less reliable than the seventies P6, which did nothing for Rover’s image and made a disaster of the brand’s short-lived return to the American market in 1980. Rover would go on to produce some decent cars, but none as advanced or impressive as the 2000 and 3500.
Rover’s subsequent misadventures and the fate of British Leyland are a story for another day. Suffice to say, the tale doesn’t have a happy ending, and today Britain’s native auto industry is either extinct or owned by foreign companies.
What the Rover P6 makes clear is that the fate of the British industry was not the result of any lack of talent. In design and engineering, the P6 was a match for any sedan in the world. That today it is little more than a historical footnote (at least outside the UK) is sad testimony to the damage done by decades of managerial blunders. The P6 is not unlike a gifted university student with a low B average: For all its flashes of brilliance, one can’t help wondering how much more it could have been if it had just applied itself a little more.

Historical exchange rates for the dollar to the pound came from Werner Antweiler, “PACIFIC Exchange Rate service, Foreign Currency Units per 1 British Pound, 1948-2007” (2007, University of British Columbia, fx.sauder.ubc. ca). Exchange rate values cited in the text represent the approximate equivalency of British and U.S. currency at the time, not contemporary U.S. suggested retail prices, which are listed separately.
