Zeppelin Airship Power – Maybach Spezial-Rennwagen

Today’s featured 1920 Maybach Spezial-Rennwagen like last weeks featured Brutus is run and operated by the Auto & Technik Museum Sinsheim.

Maybach’s first car built in 1919 is said to have used a proprietary chassis, most likely from Daimler considering that Wilhelm Maybach was not only an almost life long friend of Gottlieb Daimler, but also his former assistant.

If the 1920 date for today’s featured vehicle is correct then the this car was built before Maybach ever showed a vehicle in public, since that did not occur until the Maybach W3 appeared at the Berlin Show in 1921.

My suspicion is that like Brutus, the Napier Bentley, the GN JAP and numerous other Curtiss engined specials, the Maybach Spezial-Rennwagen is another creation made from an assortment of vintage parts.

The 6 cylinder engine for the Maybach Spezial-Rennwagen is said to have been built for use in Zeppelin’s, Maybach’s Luftfahrzeug Motoren GmbH was founded as a subsidiary of Luftschiffbau Zeppelin GmbH in order to build motors for airships in 1909.

The engine size is quoted as 23 litres which is the same as the Maybach Mb IVa
motors built from 1916 to 1918 used to power the Zeppelin airships LZ 105 to 114.

In theory the Maybach Mb IVa could produce 300 hp at sea level but because the engine was designed for maximum power at high altitude the motor had to be restrained to producing just 245hp at sea level in order to enhance it’s longevity, this is still enough to easily propel the Maybach Spezial-Rennwagen seen in these photographs at Cholmondeley Pageant of Power to 100 mph.

Herman Layher and Dietmar Gulden from the Auto & Technik MUSEUM SINSHEIM built today’s featured American LaFrance, known as Brutus, in it’s current form between 1998 and 2008.

This two ton leviathan is powered by a 650 hp 47 litre / 2863 cui BMW VI a mid 1920’s V12 bomber engine that was used in a variety of applications by the Axis nations of Germany, Spain, Japan and the Soviet Union who built these motors under licence as the Mikulin M-17. This particular one was found in a Spanish scrap yard.

The LaFrance chassis is believed to have come from a 1908 fire engine, despite it’s phenomenal weight and power it is only fitted with puny rear wheel brakes, a fact that keeps the temptation to use full throttle far from the drivers mind….

… as would the 2.8 mpg (UK) / 3.7 mpg (US) fuel consumption.

This car has no fire wall behind the engine and the driver is protected from the flywheel, that could spin at up to 2000 rpm, only by an industrial safety guard.

Brutus is considered by Herr Layher, seen at the wheel in these photographs at the Cholmondeley Pageant of Power, to be the most dangerous vehicle in the world.

With the motor turning at 800 rpm Brutus will reach 60 mph and at 85 mph it will spin it’s wheels in top gear, to date it has not been driven over 124 mph.
