Alfa Romeo Alfa 6 Classic Cars for Sale

History of the Alfa Romeo Alfa 6

Launched in 1979 after the oil crisis delayed its production, the Alfa Romeo Alfa 6 represents Alfa Romeo’s pursuit of a genuine executive saloon to challenge German rivals. Developed as the successor to the Alfa 2600, the Alfa 6 departed from the brand's transaxle layout, opting for a conventional drivetrain to suit luxury segment expectations. Known colloquially in Italy as 'Alfone,' its opulent features and dignified presence even led to use by the Italian government and the Vatican. Production ran in two main phases: the first generation from 1979 to 1983, and an updated model from 1983 to 1986, with a total of just over 12,000 cars built. Its advanced spec included power steering, central locking, electric windows, air conditioning, and magnesium wheels, underpinning its reputation as Alfa Romeo’s executive flagship.

Model History

Originally intended for a mid-1970s reveal, the Alfa 6 was delayed due to the 1973 oil crisis, meaning its styling appeared dated by the time of its launch. The first generation featured a 2.5-litre V6 with six carburettors. In 1983, Bertone modernised the exterior, replacing the round headlamps with wide-band units, revising the interior, and broadening the range of engines to include fuel-injected V6, a 2.0-litre V6 for the domestic market, and a 2.5-litre five-cylinder turbodiesel borrowed by other manufacturers. Alfa Romeo's technical focus resulted in one of the only models with a De Dion rear axle and ZF gearbox up front. The Alfa 6's production ended in 1986, with the Alfa 164 stepping in as its successor.

Highlights and Unique Features

The Alfa Romeo Alfa 6 stands out for its technical and design details: the debut of the Busso V6 engine, the only Alfa Romeo saloon with a De Dion rear axle and ZF transmission, hydraulic power steering, 5-speed manual or rare 3-speed automatic gearboxes, and extensive comfort equipment, like all electric windows, air conditioning, and even magnesium alloy wheels. With a focus on both driving refinement and comfort, the Alfa 6 found niche appreciation among buyers who wanted a flagship saloon with a sporty DNA. Collectibility is heightened in particular by original features: wooden dashboard inlays, plush interiors in leather, Pullman fabric or Alcantara, and period-correct details like electric sunblinds and original radio equipment.

Compared to other Alfa Romeo models, supply statistics show Serie 2 makes up about 58.8% of available Alfa 6s for sale, versus Serie 1’s 41.2%. Demand is split almost evenly with 50.7% for Serie 2 listings and 49.3% for Serie 1. This reflects a consistently rare supply and balanced interest from enthusiasts looking for both generations.

Technical Data

Special Editions and Collectible Models

Among the rarest variants is the Quadrifoglio Oro, distinguishable by exclusive trim and upgraded specifications. Genuine Alfa 6s with factory leather, air-conditioning, or the rare automatic gearbox are of particular interest. Documented original equipment, such as period Grandprix Roadstar radios and Italian-market details, increase provenance and desirability among committed collectors.

Weak Spots and Common Issues

The Alfa 6 requires attentive maintenance, especially on carburetor models, where regular upkeep of the carburettor setup and timing belt is crucial. Electrical issues can arise, particularly with the original wiring and era electronics, so checks of central locking, window motors and air conditioning are advised. Brake hydraulics and the unique De Dion rear axle system also need periodic inspection. Original interior and bodywork details are critical for maintaining collector value, and finding spare parts for trim and mechanicals may require sourcing from specialists.

Engine and Performance, Transmission and Handling

The Alfa 6’s performance profile centres around the smooth, strong delivery of the Busso V6, whether as the rev-happy 2.0-litre carbureted unit or the robust, fuel-injected 2.5. The five-speed manual provides a responsive, engaging drive, while the rare three-speed automatic offers comfort-oriented cruising. The combination of rear-wheel drive, power steering, and the unique De Dion rear axle results in composed handling for a large saloon, with a touch of sporting spirit typical of Alfa Romeo. Ride comfort and noise suppression were standouts for the era, while the strong brakes and balanced weight distribution enhanced road confidence.

Popular models include:

1. Alfa 6 2.5 V6 (manual): 158 PS, L-Jetronic EFI, ~195 km/h top speed – most sought after for performance.
2. Alfa 6 2.0 V6 (carb): 135 PS, specifically for Italian market users – collectible for rarity.
3. Alfa 6 2.5 Turbodiesel: Unusual for an Alfa, recognisable for its use in Range Rover and Toyota Land Cruiser, valued for robust diesel engineering. undefined

Interior, Comfort, Exterior and Design

Designed at the height of 1970s Italian luxury saloon tradition, the Alfa 6 exhibits strong, angular lines, reworked by Bertone in 1983 to address contemporary styling cues. The interior is lavish for its time: real wood inserts on the dashboard, plush seats in leather, Pullman cloth or Alcantara, a velour headliner, and period luxury details such as electric rear blinds, four power windows, and even heated windscreen options. Optional metallic paints—notably Blu-Electrico Metallizzato and silver—accentuate its stately presence. Accessories and equipment like electric aerials, headlamp washers, and factory-fitted radios were available, and genuine Alfa alloys enhance its visual appeal. High attention to detail in material choice and cabin ergonomics confirms its executive intent.

Other Features

The Alfa 6’s original ownership documents, service history, and Italian homologation records are important for authenticity. Collector’s value is heavily influenced by complete period equipment and clear provenance. Also notable is the car’s reputation as a comfortable long-distance tourer — with space, ride, and equipment levels oriented towards grand touring as much as executive use.

Summary

The Alfa Romeo Alfa 6 remains a singular offering: an Italian executive saloon with real rarity, technical intrigue, and comfort amenities usually reserved for contemporaneous German luxury cars. Today, the Alfa 6’s blend of Busso V6 performance, luxurious options, and limited production numbers make it a compelling choice for enthusiasts. Regular maintenance on mechanical and electrical systems is essential, and original features are key to sustained value. Rarity is reflected both in its historical production and current marketplace supply, which stays low and balanced across both Series 1 and 2 generations.
