Sa Majesté conduit par technologie ! - Citroen SM

If ever there was an automobile manufacturer that highlighted how conservative the automobile industry is, it would be Citroen, who during their years of ownership by Michelin really pushed the envelope with some out of the box thinking in terms of approach, technical innovation and design to their automotive solutions.

Top of the list of Citroens innovative vehicles I would put the UFO like Citroen SM launched in 1970. This GT car was born in part out of Citroens ownership of the Maserati brand. Note the inner pair of headlights turned with the steering wheel to help drivers see around corners, an innovation carried over from the Citroen DS.

Powered by a 178hp 2.7 litre / 164.7 cui (US 180 hp 3 litre / 183 cui) 90 degree V6 as used in the Maserati Merak, the SM was the most powerful front wheel drive vehicle of its time. The car featured not only self levelling suspension capable of running on just three wheels but also innovative variable assist power steering with just one turn from lock to lock, that was also self centering.

Just as the DS became known as 'La déesse' - 'The Goddess' the SM became known as 'Sa Majesté' - 'Her Majesty', though the S probably stems from 'Project S' which started the SM ball rolling and M unsurprisingly probably comes from Maserati.

Styling by Robert Opron reflected his American influenced tastes including these stainless steel fins in the rear bumper design.

The SM had an exceptionally low drag co efficient of 0.26, does anyone remember the fuss Audi made in 1982 when their C3 100, 200, 5000 series came out with a drag co efficient of 0.30 ?

Amazingly when Citroen decided to prove the SM's prowess in motor sport they chose to debut the car not on the race track but on the hard core African 1971 Rallye du Maroc which it promptly won. Later a 'bread van' version was also used in rally events.

In 1987 Jerry Hathaway turbocharged an SM and his wife Sylvia took a production class land speed record at 202 mph at Bonneville that still stands. Jerry also built a cool matching SM tow truck and trailer rig on which to transport the LSR SM.
