So no, this isn’t an Auto Union Grand Prix car, despite its looks. In fact, it was built a full 20 years after those cars dominated the European Grand Prix circuit. The “RA” cars were racing specials built by Hector Green and Jack Brewer in New Zealand between the end of WWII and the mid-1950s. Their first car kept evolving, and in 1951 they decided to replace it.

The RA4 Vanguard was the replacement, and its design and construction were heavily influenced by the pre-war Auto Unions. That’s because its builders consulted a then-declassified British intelligence document that investigated the construction of the German Grand Prix cars of the 1930s. Intriguing stuff.

Power is from a rear-mounted 2.1-liter inline-four from a Standard Vanguard that was supercharged and fitted with dual SU carburetors. Horsepower, when the car was running on methanol, was approximately 200. Wow.

The car competed regularly in New Zealand beginning in 1951 through about 1954. It’s been invited to the Goodwood Revival and has been owned by its current caretakers since 2017. Only five or six RA specials were built. You can read more about this one here and see more from this sale here.
