    The first time I ever saw and rode in a Citroen was when my friend's father purchased a new 1956 Citroen DS. That 10 year old fell in love with Citroen forever. Thirty years later while on an assignment in Strasbourg, France, I had the privilege to be driven from the Hotel Sofitel to the airport in a Citroen SM. The analogy of a magic carpet ride that Tyrrell used was perfect..they were way ahead of their time and their designs are nothing short of being artistic..beautiful machines.

    Hello Ian,
    Thanks for your amazing videos, and all the explanations you provide. I own a Citroen SM injection and I would like to share a few comments:
    • The lights are not only turning but they always stay level (horizontal) even when the car pitches . This is due to an hydraulic link in between the lights and the rear torsion bar
    • The steering wheel was the 1st one in Europe to be adjustable both in length and height.
    • The power of the assisted hydraulic steering reduces has the speed increase.
    • 1st car with a wind screen glued.
    • Like the DS it is wider on the front than in the back and the length in between the front wheel is 20cm longueur than the length in between the rear wheels.
    • The engine was designed from scratch and has no common parts with the V8. What is true is that Alfieri wanted to show to Citroen people a V6 after just a few weeks following the brief and he took a V8 and cut off 2 cylinders but this was only a moc-up.
    • The ‘puissance fiscal i.e. CV’ is calculated using a complex equation but in reality is mainly linked on the capacity of the engine; 400CC = 2CV (the famous 2 CV Citroen), 1,100cc = 6 CV, 2,000CV = 11CV , 2,670cc = 15CV for the SM and the Range Rover with 3,500cc = 20 CV
    • My understanding of the design of the front suspension is that when you take a corner and the car rolls, the surface of the tyres remain entirely in contact with the road surface, like when going strait. The wheel remains perfectly perpendicular to the road surface. And when you drive on bumpy surfaces the wheels keeps directing the car absolutely strait with absolutely no movements of the wheels to the right or to the left. And of course the steering wheel does not move at all. I think this improves the grip vs most of the conventional suspension designs. When they launched the car in 1970 they invited journalists and they pushed them to do a test which consisted in going at 100 miles/h through a big puddle with their hands off the steering wheel. Scary but the car does not deviate from its trajectory by one inch. Same in case of a front tyre puncture. Now it is true that it is set to under-steer but not that much, and with the super quick steering ratio it is quite easy to eliminate this effect and even to force the car to over-steer slightly when entering a curve. The only down side is that the front tyres do not last long…
    • The design of the back has the shape of a kammback, which is very aerodynamic indeed but the flip on the boot may also be motivated by the necessity to fit the square registration plates of Italy and USA which were square and not rectangular. Without the flip they don’t fit. NB: In my view those square plates ruin the aesthetic.
    • The SM could also be equipped with super light wheel made of resin. At the time Michelin owned a big part of Citroen and they licenced the technology developed for the rover that was sent to the moon and created this resin (sort of re enforced carbon) super light wheel (4.5Kg each instead of around 9Kg for the standard ones made of steel). Another innovation.
    • Another feature is the design of the rear suspension which makes the car to stay horizontal when braking hard and therefore shorten the braking distance by reducing transfer weight. Motor Trend registered the shorten ever braking distance when testing the SM. I have a comparative from Car and Drivers; 70-0mph : SM:178 feets, Lotus Elan +2s 130 : 186 feets, Mercdes 280 SEL 4.5 and Porsche 911S: above 210 feets.
    • The SM was the first non-American car to be awarded the price of ‘car of the year’ in 1972 by Motor Trend.
    • The SM won the rally of Maroco in 1971.
    I hope this additional features and comments will be of interest to yourself and your audience. Best, Jaime

    Great video Ian (as always); thank you for that! One correction if I may; it is a stubborn misunderstanding that the engine in the SM is a modified Maserati V8 with two cilinders lopped off. While Giulio Alfieri (Maserati’s Head Engineer) did indeed use such a modified engine (still around, in the Panini collection) to evaluate what such an engine would produce in terms of power and in torque, Alfieri then set out to develop - from scratch - the engine that was actually used in the SM.
    Big differences with the Maserati V8 of course are the location of the chains (at the end of the block on the V8; in the middle on the SM V6) and the use of an intermediary shaft on the SM engine.
    The angle of 90 degrees was chosen to keep the engine low enough to fit under the hood of the SM. A special, double, ignition system was developed to create good sparks even on the uneven firing sequence caused by the angle.
    These facts are corroborated by Maserati factory historian Ermanno Cozza, and by interviews with Alfieri himself. See the excellent book of Marc Sonnery - Maserati: the Citroen years, chapter 3.
    Ironically (and confusingly), Maserati did make a prototype of a planned, new V8 by modifying the SM V6! They wanted to use that new V8 in the new Quoattroporte (the “old” Maserati V8 was deemed too heavy and old fashioned by then). This prototype engine also still exists; it was also bought by the Panini family and later sold to Philip Kantor, who put it an SM to make the one and only SM V8!

    Thank you Iain for giving the SM the credit it deserves. I have a funny story about this car: My father was driving a CX2000 in the middle seventies and his boss, Piet, drove a DS23 Pallas, and felt he was in need of an upgrade. The Citroën dealership offered him to take an SM on one of his business trips to Germany. As Autobahns were almost empty and completely unlimited in the seventies, both Piet and my father were used to drive flat out on the Autobahns. So did Piet with the SM. As Piet was doing over 200kph he entered a curve in the Autobahn (a left-hander if I remember correctly), but as Piet new the road well, he kept his foot to the floor, which was what he always did with his DS, but at lower speeds off course. But as the curve started to tighten a little something crazy happened. Due to the high horsepower to the frontwheels of the SM, the car had an LSD, so what happened when the curve tightened, the LSD disengaged all of a sudden and this caused the car to spin immediately. And this with a speed over 200kph! The car tolled around bouncing from barrier to barrier, effectively wrecking the car. But Piet was in luck as the Autobahn was empty when it happened, he didn't hit any other traffic and got out unscaved. Of course he did not buy an SM, but opted for a Mercedes 450SEL6.9. Quite a contrast you think? Well yes,, but both cars had the same suspension, that's what Piet wanted.

    • @philiptownsend4026
      @philiptownsend4026 2 ปีที่แล้ว +3

      An interesting story. I've had cars with Torsen diffs and their effect was always totally smooth, unnoticeable, except more traction. I can't imagine the fear of the diff suddenly locking at 200kph on a fast curve. I wonder what type of diff the DM has? I even fitted the Torsen (and larger clutch) from a Rover 620ti to my MGF (apart from ratios the gearboxes were the same) and it transformed the traction in any weather with no vices whatsoever.
      Finally, what did the dealer say about the wrecking of his SM demonstrator?
      PS I also had a Citroen GS in the dim and distant. That was a wonderful car with the hydropneumatic brakes and suspension and revvy OHC air cooled flat four but service intervals were 3000 miles as it ate spark plugs and disc pads.
      Have a happy time with the SM, I am very envious.

The chase lasted about 5 minutes before fear of dying to over. The SM disappeared into the distance. They have been on my classic car list (and the DS) for ages. I have driven a few DS models and as you say, the ride feel is unique.

    I remember waiting for Johan Cruijff in my hometown near Amsterdam back in the 70s. Cruijff was there for a book signing. Making a big entrance, he skidded around the corner, screeching tyres. He obviously expected all attention to be on him when he got out, being the best footballer in the world at the time. The look on his face when the crowd ran past him and just pushed and shoved to get as close to his SM as we could. We were all in awe as we'd never seen a car as cool as that. As Ajax supporters we saw Cruijff every week, so he could wait.

    Great video, a very enjoyable watch which brought back some great memories. I did my apprenticeship at Middleton Motors in Potters Bar which was a Citroen dealership, we saw lots of SM's as the owner (Roy Middleton) was a big fan. They converted 3 to RHD as I think they were hoping to have a tie up with Citroen to import more but the oil crisis put a stop to it, would be great to know what happened to them (the boss had one that was painted black and white). They had a problem with the chain that drove the jack shaft as it didn't have a tensioner (or there was a problem with it) and developed a fix with Reynolds, as the chain was against the bulkhead the whole power unit had to come out - remember it used to take me 9 hours just to remove it! The distributor had 2 sets of 'cassette' points one mounted on top of the other which were a nightmare to set up - Middleton's developed an electronic conversion with Lumminetion but even that was complicated due to the offset firing order. As an aside I notice on your roadtest the steering wheel is down to the right slightly - there is a cam adjuster between the centralising unit (on column) and steering rack to rectify - spent ages driving up and down a straight road getting it aligned!

Maybe in the inner circles of the British collector car market he is beloved but just the thought that this classic Citroen SM being once owned by him makes my stomach turn.
    Now on to the car....This green exterior color has to be the nicest color offered by Citroen for these SM's. I have a very special history with the Citroen SM as a childhood boy. I live in the United States and these cars are even MORE rare here than the rest of Europe. But when i was growing up, my best friend's father owned a 1972??(maybe 73) Citroen SM in white exterior and camel leather interior. It had the factory 5 speed manual transmission and had the American spec round headlights behind the plastic covers in the front. It was stored away only to be extruded when his father would drive it down to the local car meetups/shows. As a side note, my small New England town has a authorized Citroen dealership back in the 1960-1970's and even after they stopped selling new cars, that dealership went on to service the car in particular and many other for years to come.
    At first, i thought the car was extremely ugly but the shape and unique character of the car began to grow on me. On weekend day, my best friend asked if i wanted to go with them to the local car show and i agreed. Both him and I had to sit in the back seat(2+2) and for being a smaller build child, it was quite comfortable. I can still remember when he pulled out of his local street onto the main road and opened it up. The sound of that Maserati engine and surge of power i felt in the backseat of that car was just amazing. When we pulled up to the show, EVERYONE was looking at us. And i'm not exaggerating. Of Course we were the only ones there in a Citroen period, let alone an SM. And when i finally got to see the hydro-pnematic suspension in action, i was in total awe.
    This video brought back all those memories and i honestly think this is the 10th time i've watched this video. So i can totally understand why so many people asked about this car in the background. And i'm so thankful that i got to ride in one of these truly unique and rare cars. Thank you Mr. Tyrrell for showcasing this vehicle.

    Was lucky enough to own two SM's - loved them both, over the years - took them all over France on grand tours which they were built for - not to be kept in a garage for ages on end - that's when they bite !!! they need to be driven - sold for good money to a Suisse gent - now have BX16v & MR-2 SW-20 to keep me sane - but life is short - so my advise if you can - go for it - own an SM drive & Enjoy it !!!

  • @scheusselmensch5713
    @scheusselmensch5713 3 ปีที่แล้ว +7

    Iain, I can assure you that the steering wheel of an SM is directly connected to the front wheels through a completely normal rack and pinion arrangement. The lack of feedback is a result of almost total hydraulic irreversibility.
    You can definitely maintain control of an SM should the engine stop and hydraulic pressure falls right down to zero in the accumulator (you could reach that state of affairs with repeated on off application of the brakes or of course a rupture in the hydraulic system). I very much like your videos, best regards and wishes for this new year. It has to be better than the last, right?
    On consideration, I've oversimplified the description. The physical link between the steering wheel and the steering box exists but one would never be aware of it unless there was a complete loss of hydraulic pressure, it then manifests as slop in the steering and of course you have to be Hercules to turn the wheels at a standstill.

    Equal length wishbones weren't "to have less grip" they made it possible to have the steering pivot point through the centre of the front wheels meant no bump steer whatsoever. Also it meant that the inside wheels were not at weird angles so in actual fact they had more grip than the inside wheels on a conventional car especially with the flexible suspension keeping those inside wheels on the ground gripping.😀 All part of what made this car one of the most stable ever built.

The DS or SM has both front suspension pivot points within the front wheel exactly inline with the centre turning axis of the wheel which gives incredible stability in comparison.

    • @UPnDOWN
      @UPnDOWN 3 ปีที่แล้ว +3

      Correct. It was achieve centre-point steering geometry. The DIRAVI steering was there to create an artificial self-centring effect, as the car ran no camber/castor so as to not interfere with the ride quality.

    Nice review. I sold my SM in 2019 after a couple of years ownership. Iain's comments on drive and handling are pretty spot-on. Its party piece is to muller speedbumps wihout noticing. On my first motorway drive a stone smashed the glass nose on one side - yes it is glass and not easy to find so I would advise protecting the nose with helicopter tape. The hydraulic pump is supposed to go at least 30 seconds before recycling which I never managed to attain and it was that plus the annoying habit of dribbling hydraulic fluid from the seals as the car was parked that I think led to to sell it. The only real issue I had during my ownership was a blown head gasket not manly kilometers after the engine had been rebuilt in Holland. The UK specialists told me there were two types of head gasket on the market - one which dissolved into porridge after a couple of 000 km and the other which never gave trouble. Sadly , the Dutch marque experts had gone for the former. I am pleased I owned mine. It scratched a longterm itch. The previous Dutch owner had spent EUR85k on making a very good example as good as he could so it sold well when I decided to pass it on with R M Sotheby in Essen in 2019.

    This leads to many people demoing driving the cars around on 3 wheels.
