1987 Alpina C2 (E30) 2.7 (204 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 in limited numbers during 1987, the C2 2.7 was the culmination of Alpina’s expertise in enhancing BMW’s already capable platforms. It wasn’t simply a modified 3-Series; it was a comprehensively engineered vehicle designed to offer a blend of performance, luxury, and exclusivity. The C2 occupied a niche position, bridging the gap between the standard BMW 3-Series and the full-blown M3, offering a more refined and comfortable driving experience while still delivering impressive performance. Alpina produced approximately 200 examples of the C2 2.7, making it a relatively rare car today.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Alpina C2 2.7 is its modified BMW M20 inline-six engine. While based on the standard M20 block, Alpina significantly altered the internals to increase displacement from 2.5 liters to 2.7 liters. This was achieved through a longer stroke crankshaft and larger pistons. Alpina also extensively reworked the cylinder head, featuring larger intake and exhaust valves, optimized porting, and a high-performance camshaft. The engine utilized Bosch Motronic fuel injection, carefully calibrated to deliver a smooth and responsive power curve. Unlike the standard BMW M20, the Alpina engine featured a lighter flywheel and a unique exhaust system designed to enhance both performance and the distinctive Alpina exhaust note. The C2 2.7 was exclusively offered with a 4-speed automatic transmission, a deliberate choice by Alpina to prioritize comfort and usability over outright track performance. This transmission was reinforced to handle the increased torque output of the modified engine.

Driving Characteristics

The Alpina C2 2.7 offered a distinctly different driving experience compared to the standard BMW 3-Series or even the M3. The 4-speed automatic transmission, while not as engaging as a manual gearbox, provided smooth and effortless acceleration. The increased displacement and optimized engine tuning resulted in a substantial increase in torque, making the C2 feel strong and responsive in everyday driving situations. The car’s suspension was also subtly modified by Alpina, featuring stiffer springs and dampers, along with a larger diameter stabilizer bar, to improve handling and reduce body roll. However, the suspension remained compliant enough to provide a comfortable ride. Compared to the M3, the C2 2.7 felt more relaxed and refined, prioritizing grand touring capabilities over aggressive cornering. The automatic transmission meant slightly slower acceleration times than the manual M3, but the C2’s superior torque made it feel surprisingly quick in real-world conditions. The power delivery was linear and predictable, making it an easy car to drive quickly.

Equipment & Trim Levels

The Alpina C2 2.7 was exceptionally well-equipped, reflecting its premium positioning. Standard features included leather upholstery, power windows, power locks, and a sunroof. Alpina also added several unique touches, such as a distinctive three-spoke steering wheel, Alpina-branded gauges, and a stainless steel exhaust system. The interior trim was typically finished in wood veneer, adding to the car’s luxurious ambiance. Optional extras included air conditioning, a premium sound system, and a limited-slip differential. Alpina offered a range of exterior color options, but many C2s were finished in Alpina Blue Metallic or Silver Metallic. The exterior also featured subtle aerodynamic enhancements, such as a front spoiler and a rear decklid spoiler, designed to improve stability at high speeds.

Chassis & Braking

The Alpina C2 2.7 utilized the standard BMW E30 chassis, but with several Alpina-specific modifications. As mentioned previously, the suspension was upgraded with stiffer springs and dampers, and a larger stabilizer bar. The brakes were also upgraded, featuring larger front rotors and calipers to provide improved stopping power. The rear brakes remained drum brakes, a cost-saving measure that was not considered a significant detriment to performance given the car’s weight and intended use. The C2 2.7 rode on Alpina-specific alloy wheels, typically 16-inch diameter, which were designed to complement the car’s sporty yet elegant appearance. The steering was a recirculating ball system, providing precise and predictable handling.

Market Reception & Comparison

The Alpina C2 2.7 was generally well-received by automotive critics, who praised its blend of performance, luxury, and exclusivity. It was seen as a compelling alternative to the standard BMW 3-Series and the M3, offering a unique driving experience that appealed to buyers who wanted a refined and comfortable sports sedan. Compared to the M3, the C2 2.7 offered a more relaxed and user-friendly driving experience, while still delivering impressive performance. The automatic transmission was a point of contention for some enthusiasts, but it was seen as a key element of the C2’s grand touring character. Fuel economy was comparable to other 2.7-liter BMWs of the era, averaging around 18-22 mpg. Reliability was generally good, although the modified engine required more frequent maintenance than the standard BMW M20.

Legacy

Today, the Alpina C2 2.7 is a highly collectible car, prized by enthusiasts for its rarity, performance, and unique character. The limited production run and the car’s exceptional condition have driven up prices in recent years. The Alpina-modified M20 engine is known for its durability and responsiveness, but it does require regular maintenance to ensure optimal performance. Finding parts can be challenging, as many components are specific to the C2 2.7. The C2 2.7 represents a significant chapter in Alpina’s history, showcasing the company’s ability to transform already excellent BMWs into truly exceptional automobiles. It remains a testament to the enduring appeal of a well-engineered and thoughtfully designed sports sedan.
