The AC 12 HP was a vehicle produced by AC Cars, originally known as Autocarriers Ltd, in the early 20th century. It was introduced in 1913 and marked a significant step forward for the company in terms of design and engineering. Powered by a 1.5-liter four-cylinder engine, the car delivered 12 horsepower, offering a notable improvement in performance over earlier models like the AC Sociable. The AC 12 HP featured a traditional four-wheeled design, which was becoming the standard for automobiles of that era, and it came with a three-speed manual gearbox that allowed for better driving control and efficiency.

The car was available in various body styles, including tourers and two-seaters, providing options that appealed to different customer preferences. It was aimed at a more affluent market, offering greater power, comfort, and sophistication compared to the more basic and utilitarian vehicles that had previously defined the company’s offerings. The AC 12 HP played an important role in establishing AC Cars as a manufacturer of high-quality automobiles, representing a significant shift towards producing more advanced and competitive vehicles.
