This is where the legend gets technical. Rolls-Royce knew a V8 was impossible. Instead, they developed a 3.5-liter, all-aluminum V6 —the first and only V6 in company history. Designed with input from the defunct Vanden Plas division, it produced a modest 155 bhp. Mated to a General Motors-sourced THM-350 three-speed automatic, it was smooth but utterly un-Rolls-like in sound.
The goal: a Rolls-Royce that was 80% of the size of a Silver Shadow, 40% more fuel-efficient, but with 100% of the prestige. The Baby was never a single prototype but a series of engineering mules built between 1974 and 1976. The most famous surviving example (chassis #CR-001) is currently held in a private collection near Birmingham.
The press was divided. The Economist called it "the anti-Rolls." Car Magazine declared it "brilliant but soulless." By late 1975, Rolls-Royce had invested over £4 million (roughly £40 million today) in the Baby. Three fully functional prototypes existed. Dealers in the US, the company's largest market, were shown sketches.
