About the Bentley 8 Litre
The Bentley 8 Litre was the final and most ambitious model developed by W.O. Bentley before the company's acquisition by Rolls-Royce. Conceived as a rival to the Rolls-Royce Phantom II, it featured a massive 8.0-litre straight-six engine with four valves per cylinder and twin-spark ignition, mounted on a robust ladder-frame chassis. Despite its immense size and weight, the 8 Litre was remarkably refined, capable of accelerating smoothly from a walking pace to 100 mph in top gear. Only 100 units were produced, as the Great Depression decimated the market for ultra-luxury cars, making original-bodied saloons highly prized by modern collectors.

Bentley 8 Litre fun facts
- W.O. Bentley's personal 8 Litre Saloon, registered GK 706, was so beloved that the company eventually bought it back for its heritage collection 75 years after he was forced to sell it.
- The engine's crankcase was made from Elektron, a lightweight magnesium alloy, to help manage the car's substantial overall weight.
- Rolls-Royce reportedly halted production of the 8 Litre immediately after acquiring Bentley because it was considered superior to their own Phantom II.
