Description

The Bentley 4.25 Litre Sports Saloon by Mulliner was a quintessential expression of British luxury and craftsmanship during the pre-war era, produced in the late 1930s. It combined Bentley’s powerful 4.25-litre inline-six engine with a sleek, tailored saloon body handcrafted by H. J. Mulliner, one of the most prestigious coachbuilders of the time.

Mulliner’s design for the Sports Saloon was elegant yet purposeful, featuring a long bonnet, sweeping fenders, and a compact rear section that contributed to a dynamic, sporting profile. The roofline flowed gracefully into the rear, giving the car a poised and balanced stance. Mulliner was known for precision and restraint in their styling, often integrating subtle design flourishes such as chrome accents, concealed door hinges, and carefully contoured bodywork that enhanced both aerodynamics and aesthetics.

Inside, the cabin was tailored to the highest standards of the era, with rich wood veneers, hand-stitched leather upholstery, and an array of polished instruments and switchgear neatly arranged across a beautifully crafted dashboard. The seating was supportive yet luxurious, designed for both comfort and extended journeys. Sound insulation and careful craftsmanship ensured a quiet and refined ride, even at speed.

Mechanically, the 4.25-litre engine delivered ample performance, capable of sustained high-speed cruising thanks to its strong torque and smooth power delivery. It was mated to a robust gearbox and featured servo-assisted mechanical brakes, which offered reliable stopping power. Independent front suspension improved ride quality and handling compared to earlier models.

The Bentley 4.25 Litre Sports Saloon Mulliner was more than a mode of transportation—it was a bespoke statement of style and status, tailored to the tastes of its original owner. Today, it stands as a rare and highly valued collector’s car, admired for its blend of elegance, engineering excellence, and the artistry of hand-built coachwork.
