1986-1987 Alpina C2 (E30) 2.7 (209 Hp)

The Alpina C2, based on the BMW E30 3-Series, represents a unique and highly sought-after collaboration between BMW and the independent German tuning house, Alpina Burkard Bovensiepen. Produced between 1986 and 1987, the C2 2.7 was the initial offering in the C2 series, designed to bridge the gap between the standard 3-Series and the more potent M3. It wasn’t simply a modified 3-Series; Alpina undertook extensive engineering changes, resulting in a vehicle with a distinct character and enhanced performance. Approximately 200 examples were built, making it a relatively rare and collectible automobile. The C2 2.7 served as Alpina’s entry into a more accessible performance market, offering a blend of luxury, refinement, and sporting capability.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Alpina C2 2.7 is the M30B27 engine, a 2.7-liter inline-six cylinder powerplant. This engine wasn’t simply dropped into the E30 chassis; Alpina extensively modified it. The block itself is based on the standard BMW M30, but Alpina employed a Mahle-Nikasil cylinder coating for reduced friction and increased durability. The crankshaft, connecting rods, and pistons were all lightened and balanced to improve responsiveness and reduce internal stresses. A high-performance camshaft with increased lift and duration, along with larger intake valves, significantly enhanced airflow. The cylinder head was ported and polished to further optimize breathing. Fuel delivery was handled by Bosch Motronic fuel injection, carefully calibrated by Alpina to deliver optimal performance and drivability. The exhaust system was also a bespoke Alpina design, featuring stainless steel construction and a free-flowing design to minimize backpressure.

While a 5-speed manual transmission was standard, a 4-speed automatic transmission was offered as an option. The automatic, while providing convenience, did slightly diminish the car’s overall performance. Alpina also modified the rear differential with a shorter ratio to improve acceleration. The engine’s characteristics are those of a classic, high-revving inline-six – smooth, linear power delivery, and a distinctive exhaust note.

Driving Characteristics

The Alpina C2 2.7 offers a driving experience that is both refined and engaging. Compared to the standard E30 3-Series, the C2 feels significantly more powerful and responsive. The lighter engine components and optimized airflow contribute to a willingness to rev, and the engine pulls strongly throughout the rev range. The manual transmission provides precise shifts and allows the driver to fully exploit the engine’s power. The optional automatic transmission, while smooth, does introduce some power loss and a less direct connection to the engine. The suspension, while based on the E30’s MacPherson strut front and semi-trailing arm rear setup, was subtly tuned by Alpina to provide a more comfortable ride without sacrificing handling. The steering is precise and well-weighted, offering good feedback to the driver. Overall, the C2 2.7 strikes a balance between performance and comfort, making it a capable and enjoyable car to drive on both the road and the track.

Equipment & Trim Levels

The Alpina C2 2.7 was positioned as a premium offering, and as such, it came equipped with a generous list of standard features. The interior was typically trimmed with high-quality leather upholstery, often in a choice of colors. Alpina-specific instrumentation, including a 200 mph speedometer and additional gauges, adorned the dashboard. Wood trim was used extensively throughout the cabin, adding a touch of luxury. Other standard features included power windows, central locking, and an upgraded sound system. Optional extras included a sunroof, air conditioning, and a limited-slip differential. Alpina also offered a range of personalized options, allowing customers to tailor the car to their specific preferences.

Chassis & Braking

The C2 2.7 utilized the standard E30 chassis, but with several Alpina-specific modifications. The suspension was slightly lowered and stiffened, and Alpina fitted stiffer anti-roll bars to reduce body roll. The braking system was upgraded with larger front brake rotors and calipers, providing improved stopping power. The rear brakes remained drum brakes on most models, although some later examples were equipped with rear disc brakes. Alpina also fitted its signature multi-spoke alloy wheels, which were lighter than the standard E30 wheels and contributed to improved handling. The overall effect of these modifications was to create a chassis that was more responsive and capable than the standard E30.

Market Reception & Comparison

The Alpina C2 2.7 was well-received by automotive critics, who praised its performance, refinement, and exclusivity. It was seen as a compelling alternative to the BMW M3, offering a more comfortable ride and a more luxurious interior. Compared to the standard E30 3-Series, the C2 2.7 was in a different league, offering significantly more power and a more sophisticated driving experience. Compared to the M3, the C2 2.7 offered a different character – less raw and aggressive, but more refined and comfortable. Fuel economy was reasonable for a performance car of its era, averaging around 20-25 mpg. Reliability was generally good, although the M30 engine is known to be susceptible to cooling system issues if not properly maintained.

Legacy

The Alpina C2 2.7 remains a highly collectible and sought-after automobile. Its rarity, combined with its unique character and performance, has made it a favorite among enthusiasts. The M30B27 engine is known for its durability and tunability, and well-maintained examples continue to provide years of reliable service. In the used car market today, C2 2.7s command premium prices, reflecting their desirability and limited production numbers. The C2 2.7 represents a significant chapter in Alpina’s history, demonstrating the company’s ability to create unique and compelling automobiles that blend performance, luxury, and exclusivity. It stands as a testament to the enduring appeal of the classic BMW E30 platform and the engineering expertise of Alpina Burkard Bovensiepen.
