1973 Austin Allegro (ado 67) Dimensions, Size & Specs

The Austin Allegro's width of about 1,615 mm (63.6 inches) is narrower than most modern hatchbacks, which often measure around 1,750 to 1,800 mm (68.9 to 70.9 inches). This narrower width made the Allegro easier to maneuver through narrow city streets and tight parking spots common in the 1970s and 1980s, enhancing its urban practicality. However, the narrower track width may have contributed to slightly less stability and less interior shoulder room compared to newer models that emphasize wider cabins for comfort and improved handling dynamics.

The Austin Allegro stands approximately 1,480 mm (58.3 inches) tall. This height provided a balance between a low center of gravity, improving handling characteristics compared to taller vehicles, and enough cabin height to offer reasonable headroom for passengers. The vehicle's relatively upright profile compared to more streamlined cars enhanced driver visibility, creating a commanding view of the road, which was a valued feature in its class. The hatchback design also ensured a functional cargo area with a flexible rear space.

While specific ground clearance figures are harder to find for the Allegro, typical small hatchbacks of that era had ground clearances ranging from 130 to 150 mm (5.1 to 5.9 inches). The Allegro was designed primarily for urban and suburban use, including paved and moderately rough roads. Its ground clearance was sufficient for standard road conditions, but it was not intended for off-road or uneven terrain. The suspension was tuned more for comfort and everyday usability rather than rugged performance.

The Austin Allegro typically weighed around 930 kg to 1,050 kg (approximately 2,050 to 2,315 lbs), depending on the exact variant and trim level. This relatively light curb weight contributed positively to fuel economy, making it economical to run at a time when fuel prices were becoming a concern worldwide. The lighter weight also helped the modest engine options deliver decent acceleration and agility for a compact hatchback of its period, striking a good balance between efficiency and everyday practicality.

The Austin Allegro hatchback comfortably seats up to five passengers, with two in front and a rear bench for three occupants. Its interior space was considered generous for its class during production years, emphasizing comfort for small families or commuters. The rear hatch design allowed for flexible cargo space; with seats up, the luggage area was modest but practical, and folding rear seats expanded cargo capacity significantly, making it suitable for grocery runs, small moving tasks, or light recreational use.

Given its length of around 4,055 mm (159.6 inches) and width of about 1,615 mm (63.6 inches), the Austin Allegro fits comfortably into a standard single-car garage. Typical garage dimensions are approximately 3,000 mm (10 feet) wide by 6,000 mm (20 feet) deep. The Allegro's compact size allows for ample space around the vehicle for opening doors and maneuvering inside the garage, making it convenient for households with typical urban or suburban garage layouts.

The Austin Allegro was designed as an evolution following the Austin 1100/1300 series, with a slightly larger and chunkier profile. The Allegro increased in overall length and height compared to the Austin 1100, with a more modern hatchback body replacing the earlier saloon and estate styles. The Allegro's wheelbase was slightly extended for improved interior space and comfort. Its dimensions were bulkier, reflecting changing consumer preferences in the 1970s for more spacious and practical family cars, although this came at the cost of some added weight and a slightly less nimble feel.

Compared to contemporary hatchbacks like the Volkswagen Golf Mk1, Ford Escort Mk2, and Vauxhall Chevette, the Austin Allegro was generally similar in size but tended to be slightly taller and less aerodynamic. For instance, the Mk1 Golf measured about 3,995 mm in length, making the Allegro marginally longer. Feature-wise, the Allegro focused on practicality and comfort rather than sporty dynamics, offering spacious interiors and flexible cargo space. While not the most modern or stylish, it offered competitive equipment for its time, targeting buyers looking for an economical and versatile family hatchback.

The Austin Allegro's compact hatchback size made it highly suitable for urban and suburban environments, where tight parking spaces and narrow streets could challenge larger saloon cars. Its smaller footprint allowed easier maneuverability and reduced parking stress. Additionally, the hatchback tailgate design offered enhanced cargo flexibility compared to conventional saloons, which usually have a separate boot. However, this compact dimension sometimes translated to less rear legroom and smaller interior volume than larger saloon vehicles, but it was a worthwhile trade-off for many buyers favoring ease of use in everyday city life.
