Pebble Beach and BMW remember the legendary 3.0CSL

17 August, 2015

For the 2015 edition of Pebble Beach’s Concours d’Elegance, BMW has come up with something very special with the world premiere of the BMW 3.0 CSL Hommage R — a car that celebrates both the 40th anniversary of BMW in North America and the heady racing success of the BMW 3.0 CSL in 1975.

1975 was the year the Bavarian manufacturer founded BMW of North America — its first official sales company outside Europe. It was also the year in which BMW Motorsport made its debut in motor-racing stateside — in the IMSA series — with a specially made BMW 3.0 CSL. Just a few weeks later, BMW recorded its first historic triumph at the 12 Hours of Sebring. This was followed by a succession of victories, including one at Laguna Seca — just 15 miles from Pebble Beach.

““Both inside and outside, the BMW 3.0 CSL Hommage R is primarily a reflection of its function,” explains Head of Design BMW Automobiles Karim Habib. “The exterior and interior design is based around the requirements of motorsport as far as the car and driver are concerned; aerodynamics and driving dynamics on the one hand, the most direct connection between driver and machine on the other. In my view, that’s something the Hommage car expresses in a very emotional way. At the same time, all the details from the BMW 3.0 CSL are present in the Hommage model. And they are all there to be discovered in their original form. It’s a bow to the 1975 car.”

Every detail of the Hommage car has its origins in the successful racing machine from 1975, but all have since been updated and integrated technically into a modern design language. The colours and graphics used, not to mention the addition of a number 25, reference the extraordinary record of success notched up by the works BMW 3.0 CSL in 1975. Indeed, the BMW 3.0 CSL Hommage R even revives details such as the ‘Bavarian Motor Works’ decals on the windscreen and rear window. Swathes of exposed carbon fibre spotlight the 1975 model’s commitment to lightweight construction and, as a cutting-edge material, help lift it into the modern era.

Mitsubishi’s secret weapon

Ewen’s Starion is a little different and special. He saved this one – literally ‘found in a paddock’ — just in time, as he relates.
“Mine is a 1983 Starion. I’ve had it about five years. I first saw it in a paddock at Ryal Bush [north of Invercargill], and I went past it three times. The third time I went back and knocked at the door, but the owner didn’t want to sell. He rang up a year later, and put a price on it, which we accepted. Only thing wrong was the motor was totally dismantled.”
Ewen then set about getting the car back to its current state.
“It took me six months to find somebody suitable to refurbish it back then. Simon Bradley at Midas in Invercargill offered to do it and he did a great job on it. The head was badly damaged around the valves, and Simon said you could get generic cylinder heads now, so he installed one, and it cost $800. It’s made such a difference to the car. Mine is an intercooled, fuel-injected turbo model, fitted with a five-speed manual gearbox. It’s a great car to drive too.”
Except for a small patch of surface rust, Ewen’s car was in surprisingly good condition despite its paddock life.

Coaching from the bench: Casting plastic knobs and rubber parts

Casting rubber items is simple if you have a good original to work with. The item doesn’t have to be perfect. You can use plasticine to smooth out cracks, and you can even make whole prototypes out of low-fire modelling clay available from craft stores if you need to. Prototypes can also be made of wood or metal.
You will need mould dams to contain the liquid urethane moulding solution until it cures. You can build boxes out of strips of wood, but I have found that small plastic boxes and bowls such as those you would use for leftovers in your fridge work well if you spray them with a mould release agent.
Temperature is important to the chemical processes involved, so work in an area that can be maintained at around 20 degrees. You will also need adequate ventilation because the fumes can be dangerous to breathe. And you will want to wear latex gloves to protect your hands.
