black brute SOLVED! Brutus with 47 liter BMW V12 engine

[grobmotorix]

who knows any details about this brute?

Looks a bit like the 20508 cc  Isotta-Maybach, raced at Brooklands by E.A.D. Eldridge and L.G.C.M Le Champion in the early 1920s

Well, double up the mentioned 20.5 litre engine capacity and it is not enough!

[D-type]

Are you sure about the capacity?   

For comparison, various aero engined cars were:
Blitzen Benz - 21.5 litres
Fiat 'Mephistopholes' - originally 10 litres, later 21.7 litres
Napier Lion (Napier-Railton and Bentley-Napier ) - 24 litres
Rolls Royce Merlin - 27 litres
Rolls Royce Kestrel - 21 litres
Liberty Engine (Babs) - 27 litres

42 litres seems large by comparison as the car doesn't appear to have or to need twin aero engines.

I am absolutely sure.

Well, this is a "new" construction based on an original old chassis, but they´ve fitted a BMW V12 airplane-engine....

And I´ve seen this thing being started and going round a recetrack - just an acoustic inferno.
The ground gravel just flew away when the gases left the exhaust pipe in 70cm height (from the ground) while it was standing...

So what is the actual displacement?

[grobmotorix]

47 litres!

The WWI aircraft engine called BMW VI was a water-cooled monster of 45842 cm³, engine weight was 510 kg.

This car, called Brutus, was built in 1925 by Hermann Layher at an american La-France chassis from 1907, using a BMW IV engine from Heinkel He 9 (an german airplane).

Well, Brutus was built in 2006, with the following components:

a 1908 American LaFrance fire engine chassis
a 1925 BMW VI aeroplane engine

which I´ve photographed in summer 2007 myself.

A beautiful brute, indeed:
