Rolls-Royce Phantom III: the only pre-war V12 Rolls-Royce
Rolls-Royce Phantom III — a luxurious pre-war car, produced from 1936–1939 and the only pre-war Rolls-Royce with a V12 engine. We delve into its history, technology, and what collectors need to know.
Phantom III in brief
The Phantom III was the largest and most advanced Rolls-Royce of its time. It was built on a separate chassis, with bodies crafted by independent coachbuilders, making many of the cars unique.
It was a symbol of luxury and status, intended for wealthy clients and high-ranking officials. Today, it's a serious collector's car.
What makes it special
The Phantom III featured innovations that were rare at the time: an independent front suspension and a V12 engine. This made the car more comfortable and quieter than previous Phantoms.
Due to its more complex technology, this model is considered particularly ambitious, and thus challenging to maintain. Experts who specialise in the Phantom III are few and far between today.
The engine and gearbox
The car is fitted with a 7.3-litre V12 engine. It was designed for smooth, quiet operation, rather than sporting performance.
The gearbox is a four-speed manual. Drive is to the rear wheels.
What to check when buying a Phantom III
The engine is the most complex part. It's essential to check the cooling system, lubrication system, and overall condition, as repairs require highly specialised knowledge and are expensive.
The body often features wooden frame elements, so it's important to check their condition. Also, verify the documents, VIN, and chassis number to ensure authenticity.
Buy only through reputable dealers or auctions, and before doing so, consult with a Rolls-Royce classic car expert.
