The Austin Allegro 1100 was a compact family car produced by British Leyland between 1973 and 1982. It was part of the Allegro range, designed as a successor to the Austin 1100/1300 series. The Allegro 1100 featured a front-wheel-drive layout and was powered by a 1.1-liter A-Series inline-four engine, producing around 48 horsepower. It used British Leyland’s Hydragas suspension system, offering a relatively smooth ride.

Despite its innovative engineering, the Allegro became known for its unconventional styling, including the infamous “quartic” (square-shaped) steering wheel in early models. While practical and comfortable, it struggled against competitors due to build quality concerns and reliability issues. The Allegro 1100 was available in various trims, including basic models aimed at economy-conscious buyers.
