ALPINA B9 classic cars for sale

History of the ALPINA B9

The ALPINA B9 marked an important step in ALPINA’s evolution from a tuning house to a manufacturer of complete vehicles. Introduced in November 1981 and produced until August 1983, the B9 was built on the BMW E28, itself the foundation for the second-generation 5 Series. ALPINA focused on significant improvements in both performance and comfort, resulting in a car that offered both everyday usability and high-speed capabilities. Visually, the B9 was distinguished by ALPINA-specific front and rear spoilers that contributed to greater stability at high speeds, as well as a refined interior with Recaro sports seats, a leather-trimmed sport steering wheel, and bespoke ALPINA instrumentation. Mechanical upgrades—and the use of premium materials—underscore the philosophy of creating a road car with a distinct motorsport feel. Exclusive production numbers (sources list between 500 and 577 units) add further value, making each B9 a true collector’s item.

Model Lineage and Generational Development

The ALPINA B9 is based on the BMW E28, the second iteration of the 5 Series produced from 1981 to 1987. Before the B9, ALPINA had already made a name for itself with B7 Turbo and C1 derivatives of earlier 5 Series models. The B9 succeeded these as ALPINA's natural evolution in the luxury performance sedan segment, utilising BMW’s more advanced E28 chassis as its platform. The B9 in turn laid the groundwork for the subsequent B10 model, which continued the tradition of performance-tuned luxury sedans under the ALPINA badge.

Highlights and Unique Features

Distinctive elements set the ALPINA B9 apart, starting with its recalibrated 3.5-litre inline-six, custom cylinder head, increased compression, and a bespoke ALPINA camshaft raising output to 245 PS and 320 Nm. Exclusive ALPINA wheels, Bilstein gas-pressure dampers and a revised braking system—ventilated front discs included—delivered an engaging ride with full control. Interior features such as Recaro sport seats, individualized ALPINA plaques with production numbers, and equipment packages tailored for spirited yet comfortable driving supported its unique position. Externally, ALPINA livery, period-correct body stripes, spoilers, and corresponding documentation attest to authenticity. Every B9 was delivered with a unique production certificate, robust documentation, and specialized accessories.

Technical Data

Special Editions and Collectibles

All ALPINA B9 units are considered special due to their low production numbers and each one’s assigned sequential number. Authenticity is backed by factory ALPINA documentation and certificates. There are no separate B9 sub-editions, but cars with full original equipment—including period accessories, numbered plaques, and complete documentation sets—are particularly valued among knowledgeable collectors.

Weak Points and Typical Faults

As with any high-performance 1980s saloon, long-term durability depends greatly on careful maintenance and proper storage. ALPINA-tuned engines require regular servicing, especially the specific cylinder head and camshaft components. The custom suspension and braking components—particularly Bilstein dampers and front ventilated discs—should be checked for wear or leaks. Most well-looked-after examples show solid body structures and minimal corrosion, but as with all E28-based models, buyers should inspect the underbody and inner sills for hidden rust, especially if records do not document preventive care. Preserved interiors, intact ALPINA badging, and production documents are signs of a superior example.

Engine, Transmission, and Handling

At the centre of the ALPINA B9 experience is its naturally aspirated 3.5-litre six-cylinder, uniquely tuned for 245 PS at 5,700 rpm and 320 Nm at 4,000 rpm. The ALPINA camshaft and optimised cylinder head enable smooth yet urgent power delivery. The 5-speed manual gearbox engages crisply, matching the responsive steering and sports suspension (Bilstein gas-pressure dampers with ALPINA-specific settings) for an agile yet composed ride. The B9’s revised aerodynamics, improved brakes, and original ALPINA wheels ensure long-distance comfort never comes at the expense of driver involvement. Most sought-after are early examples with complete provenance and original ALPINA equipment, showing production numbers and fully intact interiors. All B9 E28 models share the technical foundations, but cars with rare colours, original accessories and Recaro interiors in pristine condition command premium attention.

Interior, Comfort, and Vehicle Design

The ALPINA B9’s design remains closely tied to its era, with body contours reflecting the E28’s angular 1980s style, enhanced by ALPINA-specific spoilers and signature stripe kits. Inside, the fitment of Recaro sports seats, a leather-clad sport steering wheel, ALPINA dials, and a distinctive gear lever elevate the cockpit feel. Materials and craft signal the car’s upper-class placement, from high-quality carpets to original ALPINA trim. Special ALPINA paint schemes and liveries, optional factory accessories and documentation, including a spare key and a manufacturer’s dossier, further distinguish individual cars. Optional equipment varies, but period extras like BMW Bavaria cassette radios or sunroofs reinforce the 1980s luxury feel.

Additional Notes and Features

Each ALPINA B9 left the factory with its own historical documentation and delivery file, usually including the original notebook, spare keys, and a detailed service record. ALPINA ensured that every car was certified with authenticity documents, and most owners preserve these as part of the vehicle’s value. Many cars are highly original, with matching-numbers engines, factory paint, and complete badging—crucial for long-term preservation and appreciation in the classic car scene.

Summary

The ALPINA B9 stands as a rare and technologically advanced performance sedan, offering enthusiasts a bridge between 1980s style and ALPINA's meticulous engineering. With its potent inline-six, dynamic but refined chassis upgrades, and a distinct appearance underlined by authentic documentation and limited production, it occupies a respected place in the classic car world. Interest in the B9 E28 remains high, with buyer demand and supply both focused on this configuration, reflecting lasting appeal among knowledgeable collectors.
