1987-1992 Alpina B3 Touring (E30) 2.7 (204 Hp)

The Alpina B3 Touring (E30) 2.7, produced between 1987 and 1992, represents a unique and relatively rare offering from the Bavarian automaker Alpina. Based on the standard BMW E30 Touring (wagon), the B3 2.7 was meticulously engineered to deliver a blend of performance, practicality, and understated luxury. It occupied a niche position within the E30 range, bridging the gap between the standard 3-Series Touring models and the more focused, high-performance M3. Alpina, operating as an independent manufacturer and tuner, built these cars in limited numbers, enhancing BMW’s already capable platform with significant engine, suspension, and cosmetic upgrades. The B3 2.7 is particularly notable for being one of the first high-performance wagons of its era, appealing to enthusiasts seeking a versatile vehicle without compromising on driving enjoyment.

Technical Specifications

Powertrain & Engine Architecture

The heart of the B3 Touring 2.7 is its 2.7-liter inline-six cylinder engine, based on the BMW M20 block. However, Alpina didn’t simply drop a larger engine into the E30 chassis. Extensive modifications were undertaken to enhance its performance and durability. The engine featured a lightened and balanced crankshaft, high-compression pistons, and a specially designed cylinder head with larger valves and optimized porting. Alpina also employed Mahle pistons and a unique camshaft profile, contributing to the engine’s distinctive power delivery. Fuel injection was handled by a Bosch Motronic system, carefully calibrated to maximize efficiency and responsiveness. Unlike the standard BMW M20 engines, the Alpina version benefited from improved cooling and lubrication systems to cope with the increased power output. The engine produced 204 horsepower and approximately 210 lb-ft of torque. The B3 2.7 was typically paired with a Getrag 265 five-speed manual transmission, although a four-speed automatic was available as an option, albeit less common. The manual transmission was chosen for its robustness and ability to handle the engine’s torque, while the automatic offered a more relaxed driving experience.

Driving Characteristics

The Alpina B3 Touring 2.7 offered a distinctly refined driving experience. The 2.7-liter engine provided strong, linear power delivery throughout the rev range, making it both enjoyable on winding roads and comfortable for long-distance cruising. The five-speed manual transmission featured close ratios, allowing drivers to keep the engine in its sweet spot. The B3 2.7 wasn’t about outright acceleration like the M3; instead, it prioritized usability and a more relaxed power delivery. The suspension was also upgraded by Alpina, featuring stiffer springs, Bilstein shock absorbers, and a thicker anti-roll bar. These modifications reduced body roll and improved handling without sacrificing ride comfort. The steering was precise and well-weighted, providing excellent feedback to the driver. While the B3 2.7 wasn’t a track-focused machine, it offered a significant improvement in handling and performance compared to the standard E30 Touring models. The automatic transmission, when equipped, dulled the experience somewhat, sacrificing some responsiveness for convenience.

Equipment & Trim Levels

The Alpina B3 Touring 2.7 was positioned as a premium offering, and its equipment levels reflected this. Standard features included Recaro sport seats upholstered in high-quality cloth or leather, a sport steering wheel, and Alpina-specific exterior trim. The exterior was distinguished by subtle but effective styling cues, including Alpina front and rear spoilers, unique wheels (typically 16-inch), and Alpina badging. Inside, the B3 2.7 featured a unique instrument cluster with Alpina-branded gauges. Optional extras included a sunroof, air conditioning, and a premium sound system. The interior trim was generally more luxurious than that found in standard E30 Touring models, with a focus on comfort and refinement. Alpina offered a range of customization options, allowing customers to personalize their B3 Touring to their specific preferences.

Chassis & Braking

The chassis of the B3 Touring 2.7 was largely based on the standard E30 Touring platform, but with several key upgrades. As mentioned previously, the suspension was significantly enhanced with stiffer springs, Bilstein shock absorbers, and a thicker anti-roll bar. Alpina also reinforced the chassis to improve rigidity and handling. The braking system was upgraded with larger brake discs and calipers, providing improved stopping power. Rear disc brakes were standard, a notable upgrade over the drum brakes found on some standard E30 models. The wheels were typically 16-inch Alpina alloys, fitted with performance tires to maximize grip. The combination of these chassis and braking upgrades resulted in a vehicle that was both stable and responsive, capable of handling the increased power output of the 2.7-liter engine.

Market Reception & Comparison

The Alpina B3 Touring 2.7 was well-received by automotive journalists and enthusiasts alike. Critics praised its blend of performance, practicality, and luxury. It was seen as a unique and appealing alternative to the standard E30 Touring models and even the M3, offering a more relaxed and refined driving experience. Compared to the E30 325i Touring, the B3 2.7 offered significantly more power and improved handling. Compared to the E30 M3, the B3 2.7 was less focused on outright performance, but it offered greater comfort and practicality. The M3 was a dedicated sports car, while the B3 2.7 was a more versatile grand tourer. Fuel economy was reasonable for a high-performance vehicle of its era, but it was not a primary focus. Reliability was generally good, although the Alpina-modified engine required more frequent maintenance than the standard BMW engines.

Legacy

The Alpina B3 Touring (E30) 2.7 remains a highly sought-after vehicle among collectors and enthusiasts today. Its rarity, unique character, and blend of performance and practicality have contributed to its enduring appeal. The 2.7-liter engine is known for its durability, but regular maintenance is essential to keep it running smoothly. Finding parts can sometimes be challenging, as many Alpina-specific components are no longer in production. However, a dedicated network of Alpina specialists and enthusiasts exists to support owners. The B3 2.7 represents a significant chapter in Alpina’s history, demonstrating the company’s ability to transform already excellent BMW models into something truly special. In the used car market, well-maintained examples command premium prices, reflecting their rarity and desirability. The B3 2.7 is a testament to the enduring appeal of the classic performance wagon.
