F1 technology takes to the road
It will not escape the notice of aficionados that the new M6 engine shares its V10 configuration with the BMW F1 engine in the 2005 BMW Williams F1 car. But that is not the only link to the pinnacle of world motorsport. The engine’s manufacturing process and its electronic management system have their roots in the sport. Add to that the design, manufacture and fitting of a carbon fibre roof (the first in any series production car other than the very limited-volume M3 CSL) by BMW. Formula 1 has clearly inspired the team at M.
The V10 is not, of course, directly related to the F1 racing car’s unit– it has 5.0 litres and the F1 engine is 3.0 litres - but apart from sharing the V10 layout it is a high revving engine, like the F1 unit, and much of the inspiration for the electronics and engine design was drawn from F1 experience. The high-speed nature of the engine is a case in point. The new ‘ten-cylinder’ has broken the 8,000rpm barrier and reaches a maximum of 8,250rpm. At 8,000rpm each piston covers 20 metres a second. At 18,000rpm the pistons of the F1 engine move at 25 metres a second. The difference is that the M engine must last for a ‘lifetime’ while the F1 engine only has to travel 500 miles or so.
The brain behind the brawn
A high-speed engine requires high speed electronic management to ensure that every last ounce of performance can be extracted. To achieve this objective, BMW has developed one of the world’s most advanced engine management systems, MS S65, designed and built entirely in-house using know-how from BMW’s F1 programme
