Description
The Armstrong Siddeley 12 Plus, introduced in 1931, was a mid-range car designed to offer a blend of comfort, performance, and reliability to the British market during the interwar years. Positioned as an upgrade from the smaller 12 HP models, the 12 Plus featured several enhancements in both design and mechanical performance. It was powered by a 1.5-liter, six-cylinder engine, producing a respectable 42 horsepower. This engine provided smooth and refined power delivery, making the 12 Plus more capable on long-distance journeys and offering improved performance compared to the company’s earlier four-cylinder models.
The car was equipped with a four-speed manual gearbox, which allowed for smoother transitions between gears and a more comfortable driving experience. Its top speed, which hovered around 60 mph (97 km/h), was competitive for its class during the early 1930s. The suspension and chassis design were engineered to provide a balance between comfort and handling, making the 12 Plus a stable and composed car on the road.
Stylistically, the Armstrong Siddeley 12 Plus followed the elegant design language of the time, with its flowing lines, a distinctive upright front grille, and a spacious, well-appointed interior. It was available in several body styles, including saloon, coupe, and tourer configurations, catering to a range of customer preferences. The car’s interior was designed with comfort in mind, featuring quality materials and craftsmanship that reflected Armstrong Siddeley’s reputation for building well-finished, durable vehicles.
The Armstrong Siddeley 12 Plus became popular with middle-class buyers who wanted a dependable, stylish car that offered a step up from more basic models without venturing into the realm of high-end luxury vehicles. It was a testament to Armstrong Siddeley’s focus on quality, blending technical sophistication with a refined driving experience, helping the brand maintain its position as a respected British automaker.
