"The SM is neither a sports car nor a luxury limousine, not a prototype for proving a new concept of driving security for tomorrow. But it does combine all three of these concepts into one compete entity." – Citroën.

Combining Citröen's advanced chassis technology and Maserati's engine know-how, the SM (Série Maserati) featured DS-style hydro-pneumatic self-levelling suspension, power-assisted all-round disc brakes, self-centring steering, and steered headlamps. Maserati was responsible for the 90-degree V6 engine, and after some juggling of bore/stroke dimensions, a capacity of 2,670cc was settled on for a power output of 170bhp to fall within the 15CV taxation band. Citröen was the world leader in passenger car aerodynamics at the time, the SM's class-leading drag coefficient enabling it to reach 140mph (225km/h), making it the fastest front-wheel-drive car ever at that time.

Fuel injection arrived in 1972; an automatic transmission option became available the following year; and the engine was enlarged to 2,974cc before the model was prematurely (some would say criminally) axed in 1975 following Citröen's acquisition by Peugeot, by which time a total of 12,920 had been produced. Fondly remembered, these technically advanced and functionally beautiful cars remain highly sought after today.

This particular SM was purchased for the collection at a UK auction in 1998 (purchase invoice on file). The car has recently undergone significant recommissioning, carried out by the collection staff (invoices on file), following a lengthy period of static display. Crucially, this included a complete rebuild of the hydropneumatic suspension, as well as comprehensive mechanical recommissioning, which included repairs to the fuel pump; new fuel filter installed; carburettor stripped and rebuilt; fuel lines replaced; fuel tank removed, chemically cleaned and reinstalled; water pipes replaced; radiator removed, cleaned, repaired, and reinstalled; thermostat replaced; water pump repaired; engine oil changed; oil filter replaced; spark plugs replaced; alternator replaced; and a new battery installed.

Accompanying paperwork includes old MoT certificates; parts invoices dated 2023; and an old V5 registration document (RUF 879M). A wonderful opportunity to acquire one of these 20th Century motoring icons.
