Auto Union

A state-funded, rear-mid-engine racing car that redefined weight distribution — and proved ideology can accelerate engineering.

The Auto Union racing cars (Types A–D) were state-funded, rear mid-engine Grand Prix machines built from 1934 to 1939. Ferdinand Porsche designed the foundational P-Wagen Project, which Auto Union acquired in 1932. Their central fuel tank, forward driver position, and supercharged engines delivering up to 550 hp defined pre-war racing engineering — and established solutions still used in modern open-wheel cars.

    Four companies, one project

    Auto Union was not a single brand but a 1932 merger of Audi, DKW, Horch, and Wanderer — and it bought Porsche’s P-Wagen Project outright.

    State money, state timing

    Hitler personally approved 250,000 ℛ︁ℳ︁ for Auto Union’s racing programme after a Reich Chancellery meeting — part of a dual-track state motorsport push.

    Weight where it matters

    The driver sat far forward; the engine sat behind; the fuel tank sat centrally behind the driver — all to lock front-rear weight balance during a race.

    Silver Arrows, stopped by war

    Types A–D raced from 1934 to 1939 as dominant 'Silver Arrows' — their dominance ended only by WWII.

The written brief1 min read

What the car is and where it came from

The Auto Union racing car is a series of four Grand Prix machines (Types A–D), built from 1934 to 1939 by Auto Union GmbH — an amalgamation of Audi, DKW, Horch, and Wanderer formed in 1932. Ferdinand Porsche designed the original P-Wagen Project, which Auto Union acquired in 1932 for 75,000 ℛ︁ℳ︁.

How it works, in terms someone would actually use

The driver sits far forward in a narrow cockpit. The engine sits behind them, mid-mounted and rear-wheel drive. Fuel is carried centrally, just behind the seat, to keep weight distribution stable as the tank empties.

What it gets right

It gets weight distribution right. It gets torque delivery right — supercharged engines tuned for low-end response. It gets driver positioning right for visibility and control in a high-power, narrow-chassis car.

What it does not

It does not offer road usability. It was never intended for public roads. It does not represent independent innovation — it was built under state mandate with direct Nazi funding.

What it changed

It proved rear mid-engine layout could dominate Grand Prix racing. It set the template for fuel-tank placement in open-wheel cars — a solution still used today.

Who it is for, and who it is not

It is for engineers, motorsport historians, and students of interwar industrial policy. It is not for collectors seeking drivable classics, nor for enthusiasts of production-based performance cars.

Is it worth your time

Yes — if you care about how racing engineering solved real problems before modern computing, or how state power shaped automotive design.

Bugatti Type 35Ettore Bugatti · 1924The Bugatti Type 35 is the first holistically conceived, race-ready car sold as a complete system. It pioneered cast alloy wheels and won over 1,000 races between 1924 and 1930. Its design prioritised integration over adaptation—and succeeded globally, with factory and privateer teams alike.

Porsche 917Hans Mezger · 1969The Porsche 917 is a sports prototype race car developed by Porsche’s 1960s Race Design office under Hans Mezger’s leadership to exploit 5-litre sports car regulations. Its spaceframe chassis weighs 42 kg and is permanently pressurised with gas to detect cracks. Power comes from a new 4.5-litre air-cooled flat-12 engine designed by Mezger. It gave Porsche its first overall wins at the 24 Hours of Le Mans in 1970 and 1971, and was chiefly responsible for Porsche winning the International Championship for Makes in both years. It was initially unwieldy but improved through continuous development. Porsche later adapted it for Can-Am racing, culminating in the twin-turbocharged 917/30.

BMW M1Giorgetto Giugiaro · 1974The BMW M1 is a mid-engined, rear-wheel-drive coupé designed by Giorgetto Giugiaro in 1977. Hand-built from 1978 to 1981 as a homologation special, it was the first car developed solely by BMW M and the first mass-produced mid-engine BMW. Its fibreglass body reflects Giugiaro’s angular 'folded paper' design language. Only 453 units were produced.
