Austin Allegro: generations, engines and what to check
Austin Allegro — the British compact car produced from 1973 to 1983. In this article, we look at the Allegro generations, engines, and what you need to know if you're after this classic model.
Allegro in brief
The Allegro was Austin's compact model with front-wheel drive and a transversely mounted engine. It was offered as a saloon, hatchback, and estate (Estate), with earlier versions featuring the unusual four-sided 'Quartic' steering wheel.
Today, the Allegro is valued as a unique representative of British design from its era. Its prices and popularity are largely tied to collector interest rather than practicality.
Which generation to choose
Over its decade-long run, the Allegro was updated several times — the Mk1, Mk2, and Mk3 versions are most commonly distinguished. Later cars saw changes to the interior, equipment, and some body details.
When choosing, pay attention to the body condition and history. The Estate version is more practical, while the Vanden Plas stands out with its plusher interior.
Engines and gearboxes
The Allegro was offered with various petrol engines — from smaller 1.0–1.1 L units to larger 1.5–1.7 L ones. Exact specifications vary by generation and year.
Most commonly, you'll find a manual gearbox, although there were automatic versions too. The suspension and gearbox of all older cars are worth a thorough inspection.
What to check when buying a used Allegro
The key thing is rust. British cars from this era often rotted away, so check the sills, wheel arches, front bumper, and boot.
The Allegro used a Hydragas suspension — check if the car hasn't settled and if there are no suspension fluid leaks. Such systems can only be repaired by a specialist.
Look into the paperwork, mileage, and previous repairs. Some cars have been restored, but not always to a high standard.
