The W125's supercharged 5.6 liter engine

2y ago


The W125's supercharged 5.6 liter engine produced 595 bhp (444 kW) and it had somehow been shoehorned into a chassis so light, that it fell under the 750 kg limit by a single kilogram. The engine used desmodromic valve actuation for each of the four valves per cylinder, and the Roots supercharger was located downstream of the twin carburettors.⠀⠀

In Formula One racing itself, the W125's horsepower figure was not equaled for nearly half a century, when turbo-charged engines reappeared during the eighties.⠀
