Austin Allegro (1973-82)

Overview: The **Austin Allegro**, launched in **1973**, was a crucial model for **British Leyland** and the Austin brand, as it was intended to replace the highly successful **Austin 1100/1300**. However, its significance was mixed—it was both a bold step forward and a source of controversy.

Key Significance:

- **First British Leyland-designed Austin**: Unlike its predecessor, which was developed under BMC, the Allegro was one of the first cars designed entirely under **British Leyland** after the 1968 merger.

- **Introduction of Hydragas Suspension**: It featured **Hydragas suspension**, an evolution of the **Hydrolastic system**, designed to improve ride comfort.

- **Distinctive Styling**: The Allegro had a **rounded, bulbous design**, which was a departure from the sharp-edged styling trends of the time. This was influenced by the need to accommodate the **E-Series engine**.

- **Missed Opportunity for a Hatchback**: Despite its shape, the Allegro was **not a hatchback**, as British Leyland wanted to reserve that feature for the **Austin Maxi**.

- **Sales & Reputation**: While it sold **over 640,000 units**, it failed to match the success of the **1100/1300**, and its reputation suffered due to **quality control issues** and **design compromises**.

The Allegro was meant to be a **modern, forward-thinking replacement**, but it struggled to live up to expectations. It remains one of the most debated British cars of its era.

COMMON FAULTS

Please Note: Common Faults in Regularly Used Vehicles vs. Low-Mileage Stored Vehicles that have been used consistently over many years, accumulating approximately 10,000–12,000 miles annually, are more prone to common faults due to regular wear and tear. These issues typically arise from the natural aging of components subjected to frequent use, such as engine parts, suspension systems, brakes, and tires. In contrast, vehicles with low mileage that have been stored or preserved are likely to experience different types of issues. These vehicles are often better maintained to ensure their longevity and may avoid some of the typical wear-and-tear problems seen in regularly driven cars. However, they can still face unique challenges such as degradation of rubber seals, corrosion from prolonged inactivity, or fuel system issues caused by old or stagnant fuel.

1. Reputation and Infamy:

• The Allegro had a reputation for being less reliable than your flaky Wi-Fi during peak streaming hours. It’s like it whispered to its owners, “Hey, let’s play a game called ‘Breakdown Bingo’!”

• The build quality? Well, let’s just say it wasn’t exactly German-engineered precision. The Allegro’s panels seemed to have a love-hate relationship with rust—mostly hate.

2. A-Plus Engines:

• Now, here’s where the plot thickens (like a good British stew). In 1980, the Allegro got a heart transplant—the A-Series engines waved goodbye, and the A-Plus engines waltzed in.

• The A-Plus engines were like the Allegro’s therapy session: better made, more reliable, and longer-lived. The 1.0-litre version churned out a modest 44 horsepower, while the 1.3-litre flexed its muscles with 61 horsepower. Torque? Oh, it had torque—52 lb-ft and 69 lb-ft, respectively. Not bad for a car that looked like it moonlighted as a geometry teacher.

3. Hydragas Suspension and Five Gears:

• On the bright side, the Allegro floated on the Hydragas suspension system. It’s like the car was saying, “I’m not just a car; I’m a gentle cloud with wheels!”

• And guess what? Five gears! That’s right, the Allegro was ahead of its time. It’s like it winked at other cars and said, “I’ve got more gears than your average sitcom plot twist!”

4. Cult Appeal and Rising Value:

• Despite its quirks, the Allegro has become a cult classic. It’s the automotive equivalent of that indie band you secretly love but pretend you don’t.

• The 1979 Equipe special edition? Worth double the money of its standard counterpart. And all Allegros are slowly rising in value—like a fine wine, but with more square steering wheels.

*****

Generations

1. **First Generation (1973–1982):**

- The Allegro made its grand entrance in 1973, replacing the earlier Austin 1100 and 1300 models. It was like the new kid in school, eager to make friends.

- This generation featured the iconic rounded styling, the quartic steering wheel (yes, the square-ish one), and the Hydragas suspension system. It was all about being unconventional and British to the core.

2. **A-Plus Engines and Midlife Refresh:**

- Around 1980, the Allegro got a heart transplant. Out went the A-Series engines, and in came the A-Plus engines. These were like the Allegro's second wind—a bit more reliable and longer-lived.

- The midlife refresh also brought some cosmetic changes, but the Allegro's distinctive character remained intact. It's like it said, "I might be quirky, but I'm consistently quirky!"

3. **Special Editions and Rising Value:**

- Throughout its production run, the Allegro had special editions like the 1979 Equipe. These were like limited-edition vinyl records—collectible and worth a nod of approval.

- And guess what? All Allegros are slowly rising in value. It's like they're whispering, "Invest in me; I'm not just a car; I'm a rolling piece of nostalgia!"

Trim Levels

During its production years from 1973 to 1982, the Austin Allegro offered a variety of trim levels to suit different tastes and budgets.

1. **Austin Allegro 1100 Base/De Luxe:**

- The entry-level Allegro came with a modest 1.1-liter engine. It was like the sensible kid in the family—reliable and unpretentious.

- Features were basic, but it got you from A to B without any jazz hands. No frills, just wheels.

2. **Austin Allegro 1300 Base/De Luxe/Super de Luxe:**

- Stepping up a notch, the 1300 models offered—you guessed it—a 1.3-liter engine. More oomph, more possibilities!

- The "Super de Luxe" variant even threw in a dash of luxury. Leatherette seats? Check. Fancier trim? Check. It's like the Allegro put on a tuxedo for a night out.

3. **Austin Allegro 1500 Super de Luxe/Special:**

- The 1500 Super de Luxe cranked things up. It had—you guessed it again—a 1.5-liter engine. Power, baby!

- And the "Special" trim? Well, it was special. Maybe it whispered sweet nothings to its owner while cruising down the motorway.

4. **Austin Allegro 1750 Sports/Sports Special:**

- Now we're talking! The 1750 models were the sporty siblings. They flexed their muscles with—you guessed it (last time, promise)—a 1.75-liter engine.

- The "Sports Special" variant? Picture it: racing stripes, alloy wheels, and a spoiler. It's like the Allegro decided to moonlight as a rally car.

5. **Estate (Three-Door) Variant:**

- Since 1976, the Allegro also offered a three-door estate version alongside the two- and four-door saloons. It's like the Allegro said, "Why should hatchbacks have all the fun?"

- Practicality and quirkiness in one package—what more could you ask for?

*****

Designer/Dimensions

The **Austin Allegro** (1973–1982) was designed by **Harris Mann**, a British Leyland stylist known for his work on wedge-shaped designs like the **Princess**. However, the Allegro’s final form was altered due to engineering constraints, leading to its more rounded, bulbous shape.

**Dimensions**

- **Wheelbase:** 2,438 mm (96 in)

- **Length:** 3,861 mm (152 in) (saloon), 3,993 mm (157.2 in) (estate)

- **Width:** 1,600 mm (63 in)

- **Height:** 1,397 mm (55 in)

- **Kerb Weight:** 869 kg (1,915 lbs) (approx)

The Allegro was intended as a modern replacement for the **Austin 1100/1300**, but its unconventional styling and infamous **quartic steering wheel** made it a divisive model.

- It ranked **between fourth and seventh** in the UK sales charts throughout the 1970s but never dominated the market.

- The **Allegro 2 (1975)** improved some flaws, but by then, its reputation had suffered, and it never fully recovered.

- The **Allegro 3 (1979)** was a well-built, mechanically robust car, but it was too late to reverse public perception.

**Reasons for Limited Success**

- **Unconventional Styling:** The Allegro’s **bulbous shape** and **quartic steering wheel** were widely criticized development story - AROnline](https://www.aronline.co.uk/cars/austin/allegro/ado67-development-story/).

- **Hydragas Suspension Issues:** While innovative, it struggled with potholes and cornering stability.

- **Market Misalignment:** Buyers preferred more conventional designs like the **Ford Cortina** and the **Volkswagen Golf**, which set new standards for small family cars.

- **British Leyland’s Struggles:** The Allegro’s reputation was further damaged by **British Leyland’s financial troubles and nationalization** development story - AROnline](https://www.aronline.co.uk/cars/austin/allegro/ado67-development-story/).

Despite its shortcomings, the Allegro has gained a cult following among enthusiasts today.

Highest Sales Figures by Country

The **Austin Allegro** (1973–1982) saw its highest sales figures in the **United Kingdom**, where it was primarily marketed. Despite British Leyland’s hopes for strong European sales, the Allegro struggled in overseas markets. Here’s a breakdown:

**Highest Sales Figures by Country**

- **United Kingdom** – The majority of the **642,350 units** produced were sold domestically.

- **France** – British Leyland expected strong sales, but the Allegro faced stiff competition from **Renault, Peugeot, and Citroën**.

Engine/s

During its production years from 1973 to 1982, the Austin Allegro offered a variety of engines to power its unconventional charm. Buckle up, because here's the lineup:

1. **1.0-Litre A-Series Engine:**

- The entry-level Allegro came with a pint-sized 1.0-liter A-Series engine. It was like the sensible kid in the family—reliable and unpretentious. Not a powerhouse, but it got the job done.

2. **1.1-Litre A-Series Engine:**

- Stepping up a notch, the 1.1-litre A-Series engine provided a tad more oomph. It's like the Allegro decided to stretch its legs a bit.

- These smaller-engined models were paired with a four-speed gearbox. Shift, shift, shift—like a polite conversation in gear form.

3. **1.3-Litre A-Series Engine:**

- The 1.3-litre A-Series engine was the middle child—neither too small nor too big. It struck a balance between efficiency and pep.

- Again, four-speed gearbox for this one. It's like the Allegro had a favorite dance move: the gear shuffle.

4. **1.5-Litre E-Series Engine:**

- Now we're talking! The 1.5-litre E-Series engine brought more horses to the party. Power, baby!

- And guess what? The 1.5-litre and the sportier 1.75-liter variants both had five-speed gearboxes. It's like the Allegro said, "I've got more gears than your average sitcom plot twist!"

5. **1.75-Litre E-Series Engine:**

- The 1.75-liter model was the sporty sibling—the one that flexed its muscles. It had torque, it had attitude.

- Five-speed gearbox? Check. Racing stripes? Maybe not, but it definitely dreamed of them.

*****

Performance

**1. Engine Specs:**

- The Allegro 1100 was powered by a 1.1-liter inline-4 OHV engine. It wasn't exactly a powerhouse, but it had its own modest charm.

- Picture this: 50 PS (that's 49 bhp for our friends across the pond) humming away at 5250 rpm. Torque? A respectable 81 Nm (60 lb-ft) doing its thing at 2450 rpm. Not bad for a car that looked like it moonlighted as a geometry teacher!

**2. Performance Figures:**

- Let's talk acceleration. The 1000-meter sprint? The Allegro 1100 managed it in approximately 40.4 seconds. Not exactly breaking land-speed records, but it had a steady pace.

- Top speed? A respectable 133 kph (that's around 82 mph). It's like the Allegro said, "I'm not in a hurry; I'm here for the scenic route!"

**3. Fuel Efficiency:**

- Now, let's chat about sipping tea—err, I mean fuel. The Allegro 1100 averaged around 10.2 to 8.2 liters per 100 kilometers (that's 23 to 29 mpg US or 28 to 35 mpg UK).

- It's like the Allegro had a sensible side, balancing performance with frugality. "Why rush when you can enjoy the journey?" it whispered.

**4. Lap Times and Handling:**

- On the track, the Allegro 1100 circled Linas-Montlhéry (a 9-kilometer circuit) in approximately 5 minutes and 21.40 seconds. Not exactly setting the asphalt on fire, but it had its own rhythm.

- Handling? Well, it wasn't a nimble sports car, but it waltzed through corners with a certain grace. Like a ballroom dancer in sensible shoes.

**5. Quirkiness Factor:**

- Of course, we can't ignore the Allegro's unique styling—the rounded panels, the quartic steering wheel, and the Hydragas suspension. It was like the car said, "I'm not just transportation; I'm an experience!"

- And you know what? Despite its quirks, the Allegro has gained a cult following. It's the automotive equivalent of that indie band you secretly love.

- **SAE 40 Non-Detergent Oil** – Some restorers prefer this for maintaining original lubrication properties.

For optimal performance, ensure the oil meets **API GL-4** standards, as GL-5 oils contain additives that may harm brass synchros.

Tyres: The **Austin Allegro** (1973–1982) originally came fitted with **145 R13 cross-ply tyres**, which correspond to a **radial equivalent of 145R13**. This size was chosen to balance ride comfort, durability, and handling characteristics suited to the car’s suspension setup.

**Modern Equivalents (2025)**

Several manufacturers still produce tyres suitable for the Allegro, ensuring authenticity while improving performance with modern rubber compounds:

- **Pirelli Cinturato CA67 145HR13** – A period-correct steel-belted tyre with excellent grip and durability.

- **Michelin XAS 155HR13** – A high-quality classic tyre offering improved wet-weather performance.

- **Dunlop SP Sport Aquajet 175/70R13** – A reliable choice for maintaining originality while benefiting from modern tread design.

- **Avon CR6ZZ 175/70HR13** – A premium option with enhanced handling characteristics.

For authenticity, **cross-ply tyres** are still available, but most restorers opt for **radial tyres** due to their superior road-holding and longevity. 

**

Petrol: The **Austin Allegro** (1973–1982) originally required **four-star leaded petrol**, which had an **octane rating of 98 RON**. This was the standard fuel for most British Leyland cars of the era, ensuring smooth combustion and optimal performance for the **A-Series and E-Series engines**.

**Modern Equivalents (2025)**

Since leaded petrol is no longer available, suitable alternatives include:

- **Super Unleaded (97/98 RON)** – Closest match to the original fuel, available from brands like **Shell V-Power** and **BP Ultimate**.

- **E5 Premium Unleaded (97 RON)** – Contains up to **5% ethanol**, making it safer for classic engines than E10.

- **E10 Unleaded (95 RON)** – Usable but may require **lead replacement additives** to protect valve seats.

- **Lead Replacement Petrol (LRP)** – Specially formulated for classic cars, offering **valve seat protection**.

For best results, using **Super Unleaded with an additive** ensures proper lubrication and prevents premature wear.

Racing

The Austin Allegro, a small family car produced by British Leyland from 1973 to 1982, wasn't particularly known for its racing prowess. However, there were some light-hearted drag racing events where the Allegro participated. In one instance, an Allegro completed a quarter mile run in 22.36 seconds with a terminal speed of 58.22 mph, earning it the title of this year's "Slow Car Club" champion⁶. Despite its unconventional styling, the Allegro found its place in automotive history, even if not on the racetrack!
