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

The Alpina C2 Cabriolet, based on the BMW E30 platform, represented a unique blend of luxury, performance, and open-air motoring. Produced between February 1986 and July 1987, the C2 Cabriolet was one of Alpina’s limited-production models, building upon the standard 3 Series Cabriolet with significant mechanical and aesthetic enhancements. This specific 2.7-liter (209 hp) variant occupied the top echelon of the E30 Cabriolet range, offering a more potent and refined experience than the standard BMW offerings. Alpina’s approach wasn’t simply about adding power; it was about carefully engineering a complete package that enhanced the driving experience while maintaining a high level of comfort and usability.

Technical Specifications

Powertrain & Engine Architecture

The heart of the Alpina C2 Cabriolet was its 2.7-liter inline-six engine, based on the BMW M20 block but extensively modified by Alpina. While sharing the basic architecture with BMW’s M20 engine, Alpina significantly altered the cylinder head, increasing port size and optimizing the combustion chambers for improved airflow. The engine featured a high-compression ratio and a specially designed camshaft, contributing to its increased power output of 209 horsepower. Fuel delivery was managed by Bosch Motronic fuel injection, ensuring precise control over the air-fuel mixture. The engine’s robust bottom end, coupled with a balanced crankshaft, allowed for smooth and reliable operation. The engine was mated to a ZF four-speed automatic transmission, specifically chosen for its durability and ability to handle the increased torque. This transmission featured a torque converter lock-up clutch, improving fuel efficiency at cruising speeds.

Driving Characteristics

The C2 Cabriolet’s driving experience was a notable step up from the standard E30 Cabriolet. The 2.7-liter engine delivered strong, linear power throughout the rev range, making it responsive in various driving situations. While the four-speed automatic transmission wasn’t as engaging as a manual gearbox, it provided smooth and effortless shifts. The all-wheel-drive system, a key differentiator for Alpina, provided excellent traction, particularly in inclement weather. The C2 felt planted and stable, inspiring confidence on winding roads. Compared to the higher-revving BMW M3, the C2 offered a more relaxed and refined driving experience, prioritizing usability and comfort alongside performance. The automatic transmission, while not maximizing acceleration, made the C2 a comfortable grand tourer.

Equipment & Trim Levels

The Alpina C2 Cabriolet was generously equipped, reflecting its premium positioning. Standard features included leather upholstery, power windows, central locking, and a high-quality sound system. Alpina-specific touches were evident throughout the interior, including unique wood trim, special instrumentation (including a 260 km/h speedometer), and Alpina-branded steering wheel and shift knob. Optional extras included a limited-slip differential, which further enhanced traction, and a more comprehensive sound system. The exterior featured Alpina’s signature front and rear spoilers, unique alloy wheels, and subtle badging. The interior trim was typically a combination of dark colors, emphasizing the car’s sporty yet luxurious character.

Chassis & Braking

The C2 Cabriolet benefited from Alpina’s expertise in chassis tuning. The suspension was modified with stiffer springs and dampers, reducing body roll and improving handling. Alpina also fitted a thicker stabilizer bar to further enhance stability. The braking system consisted of ventilated disc brakes on all four wheels, providing ample stopping power. The all-wheel-drive system distributed power to all four wheels, enhancing traction and stability, particularly under acceleration and in slippery conditions. The chassis modifications were carefully calibrated to provide a balance between sporty handling and comfortable ride quality.

Market Reception & Comparison

The Alpina C2 Cabriolet was well-received by automotive journalists and enthusiasts alike. Critics praised its blend of performance, luxury, and exclusivity. The all-wheel-drive system was particularly lauded for its ability to provide confident handling in all weather conditions. Compared to the standard BMW 3 Series Cabriolet, the C2 offered a significant performance upgrade and a more refined driving experience. Fuel economy, while not a primary concern for C2 buyers, was reasonable for a high-performance vehicle of its era. Reliability was generally good, benefiting from Alpina’s meticulous engineering and use of high-quality components. However, maintenance costs were higher than those of a standard BMW due to the specialized nature of the Alpina components.

Legacy

Today, the Alpina C2 Cabriolet is a highly sought-after collector’s car. Its limited production numbers and unique combination of features make it a rare and desirable vehicle. The 2.7-liter engine and four-speed automatic transmission have proven to be relatively reliable, although regular maintenance is essential to keep these cars in top condition. Parts availability can be a challenge, as many components are specific to Alpina. However, a dedicated network of Alpina specialists and enthusiasts exists to support owners. The C2 Cabriolet represents a high point in Alpina’s history, showcasing the company’s ability to create truly special and engaging automobiles. Its enduring appeal lies in its blend of performance, luxury, and exclusivity, making it a timeless classic.
