Rover SD1

Rover SD1 at a glance

The SD1 belongs to the British Leyland chapter of the brand told in our history of Rover; the catalogue entries are in our Rover section, and other British saloons of the period are in our classic cars section.

Specialist Division car number one

The name says where it came from: SD1 stood for Specialist Division project number one inside British Leyland. The car was meant to replace the technically sophisticated but ageing Rover P6, and from the P6 it kept only the all-aluminium V8.

David Bache drew a long, low five-door fastback whose nose recalled the Ferrari Daytona and 365 GTC/4. Spen King's engineering was much simpler than the P6's: MacPherson struts at the front and a live rear axle with a Watts linkage. The jury of European Car of the Year chose the Rover 3500 for 1977, and the car and its design team were also named Midlander of the Year in 1976.

V8 launch, sixes and the four-cylinder 2000

The 3500 arrived first, with the V8 and, on Motor Sport's test car, a five-speed manual gearbox. Rover claimed 116 kW (155 bhp), although Wikipedia notes that cars as sold peaked at about 99 kW (133 bhp). Bill Boddy of Motor Sport, testing the car in November 1976, reported more than 120 mph (193 km/h), 0-60 mph in under 8.5 seconds and 23.2 mpg, and gave the price as GBP 4,750, or under GBP 4,850 with electric windows.

The six-cylinder 2300 and 2600, developed from the Triumph engine, followed in 1977 after production problems had delayed the full range. Lancaster Insurance's history quotes 104 mph (167 km/h) for the 2300 and 117 mph (188 km/h) for the 2600, at GBP 5,342 and GBP 5,800 new; the 2300 went without the 2600's rev counter, five-speed gearbox and central locking. The V8-S of 1979 became the 3500 SE in 1980, and the first Vanden Plas models appeared in late 1980.

The 1982 Series 2 and the Vitesse

Early cars suffered from poor build quality, quick-wearing trim, flaking paint and ventilation problems that lasted until 1980. Production moved to Cowley in 1981, and the facelifted Series 2 of early 1982 brought flush headlamps, a deeper rear window with a wash-wipe and wood on the dashboard and door cards. The range widened downwards with the 2000 and the VM-engined 2400 SD Turbo, which returned about 30 mpg.

At the top sat the Vitesse. Its fuel-injected V8 gave 142 kW (190 bhp) and 220 lb ft (298 Nm), Hagerty UK quotes 135 mph (217 km/h) and 0-60 mph in 7.1 seconds, and the car rode on 15-inch alloy wheels. Hagerty counts 3,897 Vitesses, of which 363 were automatics, while Car & Classic gives 3,987. The Twin Plenum of 1985-1986, with intake changes engineered by Lotus, was built to homologate the racing car. Rover never announced a power increase, though the press reported 157-164 kW (210-220 bhp). How many were built is disputed: Octane and Car & Classic give 500, Wikipedia 200-250 against a planned 500.

Touring car wins and police patrols

British Leyland's motorsport department saw the car's racing potential in 1980, and Tom Walkinshaw Racing ran the works cars: Steve Soper and René Metge won the 1983 RAC Tourist Trophy, Andy Rouse took the 1984 British Saloon Car Championship, and Jeff Allam and Armin Hahne won the Group A class at the 1984 Bathurst 1000. In 1985 Walkinshaw and Win Percy won six rounds of the European Touring Car Championship, and Tony Pond won the Group A category of the British Rally Championship.

The same V8 made the SD1 a patrol car for many British forces, among them the Metropolitan Police, West Midlands Police and Grampian Police. Upmarket, it sat below the Jaguar XJ inside British Leyland and competed with the BMW 5 Series of the time, covered in our BMW 5 Series history.

The SD1 ended in July 1986, with the last Vitesse, registered D 537 PUK, leaving the factory that month. Its successor was the front-wheel-drive Rover 800.

Rover SD1 today: what to check when buying

Rust is the first check. Hagerty UK lists the wheelarches, door bottoms, floorpans, boot floor, bonnet, tailgate, lower grille surround, the area around the windscreen and the steel around any sunroof; the sills usually survive thanks to the pressure ventilation system. Octane adds the rear suspension mounts and front inner wings. On a Vitesse or Twin Plenum, check the chassis number, because a car that looks like a Vitesse may have started life as a standard 3500.

The V8 needs regular oil changes to protect the camshaft and tappets, and a neglected cooling system leads to blown head gaskets. Six-cylinder engines suffer from sludged oil feeds to the camshaft and rockers, so change the oil every 3,000 miles or yearly and replace the toothed timing belt soon after purchase. The 2000 and the turbodiesel are durable, and the gearboxes are reliable and easy to fix. Almost everything is available, including original body panels and trim, though model-year changes make ordering the right electrical part harder.
