Alpina unveils D5 Bi-Turbo: 345hp diesel saloon targets long-distance drivers
The new Alpina D5 Bi-Turbo, based on the BMW 5 Series, delivers 345hp from a 3.0-litre twin-turbo diesel while matching the fuel economy of the standard 530d.
Alpina, the renowned BMW tuning specialist, has unveiled the D5 Bi-Turbo, a diesel-powered performance saloon based on the latest BMW 5 Series. This new model arrives hot on the heels of the B6 Bi-Turbo Cabrio and continues Alpina’s tradition of blending high performance with everyday usability and efficiency. Revealed in September 2011, the D5 Bi-Turbo is designed for drivers who want more power and exclusivity than the standard 530d, yet who are not drawn to the high running costs and focused character of the M5.
The D5 Bi-Turbo stands out by offering impressive performance figures while maintaining the fuel economy expected from a diesel executive saloon. Alpina’s approach ensures that the car is not just about speed, but also about comfort, practicality, and long-distance capability. This makes it a compelling alternative in the executive car segment, particularly for those who spend significant time on the motorway or require a car that can handle both business and family duties.
Engine and Performance
At the heart of the D5 Bi-Turbo is a 3.0-litre straight-six diesel engine, fitted with two turbochargers. Alpina’s modifications raise the output to 345hp and 700Nm of torque, a significant increase over the standard BMW 530d’s 241hp. This engine is mated to an eight-speed ZF Switch-Tronic automatic gearbox, which has been revised by Alpina for sharper response and smoother, faster shifts. The result is a saloon that can sprint from 0 to 100km/h in 5.2 seconds and reach a top speed of 270km/h (168mph).
Despite the substantial performance boost, the D5 Bi-Turbo retains diesel efficiency, with a claimed combined fuel consumption of 6.2 litres per 100km. This matches the fuel economy of the less powerful 530d, making the D5 Bi-Turbo particularly attractive for high-mileage drivers and those seeking to balance pace with running costs.
Alpina’s Diesel Legacy
Alpina has a well-established history of developing high-performance diesel models. The D5 Bi-Turbo follows in the footsteps of the D10 Bi-Turbo from the late 1990s, which was also based on the BMW 5 Series. The D10 Bi-Turbo was notable for holding the record as the fastest production diesel saloon of its time and for its success in endurance racing, including a victory at the 24 Hours of Nürburgring in 1998 with a diesel-powered BMW. This motorsport pedigree helped establish Alpina’s reputation for combining speed, comfort, and efficiency in its diesel offerings.
The D5 Bi-Turbo continues this tradition, offering a blend of long-distance comfort, high-speed cruising, and low running costs. Alpina’s ongoing commitment to diesel performance is reflected in the engineering of the D5 Bi-Turbo, which aims to provide a unique proposition in the executive car market by merging real-world usability with impressive driving dynamics.
Chassis and Driving Experience
The chassis of the D5 Bi-Turbo is tuned to strike a balance between comfort and agility, rather than pursuing the aggressive set-up of the M5. Both the saloon and Touring estate models are equipped with Alpina’s signature 20-inch Classic alloy wheels, paired with Michelin Pilot Super Sport tyres. This combination enhances grip and gives the car a distinctive, purposeful appearance.
Alpina has also upgraded the suspension and braking systems to ensure the D5 Bi-Turbo can handle the increased power while maintaining the comfort expected from a 5 Series-based model. The eight-speed automatic gearbox benefits from Alpina’s software calibration, allowing for rapid gear changes during spirited driving and relaxed, low-rev cruising on the motorway. This duality makes the D5 Bi-Turbo suitable for both dynamic driving and long-distance travel.
Alpina’s attention to detail in chassis tuning ensures that the D5 Bi-Turbo delivers a refined ride without sacrificing the dynamic ability that drivers expect from a performance saloon. The result is a car that feels composed and comfortable, yet capable of delivering engaging handling when required.

Design and Features
Visually, the D5 Bi-Turbo is distinguished by subtle yet purposeful bodywork changes, including the trademark Alpina front spoiler and the 20-inch Classic wheels. These styling cues give the car an understated but assertive look, in line with Alpina’s philosophy of discreet performance.
Inside, the D5 Bi-Turbo features bespoke trim options, Alpina badging, and unique instrumentation. The interior retains the luxury and comfort of the standard 5 Series, while adding exclusive touches that highlight the car’s special status. Both saloon and Touring (estate) versions are available, offering buyers the choice between a traditional executive saloon and a more practical family car with ample luggage space.
Alpina’s approach ensures that practicality is not sacrificed in pursuit of performance. The Touring model, in particular, appeals to those who require versatility for family or business use, while still enjoying the benefits of a high-performance vehicle.
Market Context and Rivals
The D5 Bi-Turbo occupies a unique position in the executive saloon market. While BMW’s own M5 offers greater outright power, it does so with a petrol engine and higher fuel consumption. In contrast, the D5 Bi-Turbo delivers near-M5 performance with the efficiency of a diesel. Mercedes-Benz and Audi have offered high-performance diesel models in some regions, but Alpina’s blend of power, efficiency, and exclusivity sets the D5 Bi-Turbo apart.
The D5 Bi-Turbo’s status as a low-volume, hand-finished model from Alpina’s Buchloe workshops adds to its appeal. For buyers considering alternatives, the D5 Bi-Turbo’s combination of diesel efficiency, strong performance, and bespoke engineering makes it an attractive proposition. The limited production numbers and attention to detail further enhance its desirability among enthusiasts and collectors seeking something different from mainstream executive saloons.
Ownership and Availability
Production of the D5 Bi-Turbo takes place at Alpina’s facility in Buchloe, Germany, using BMW-supplied 5 Series bodyshells and components that are extensively reworked and upgraded. This process allows Alpina to offer a car that combines BMW’s renowned reliability and refinement with the exclusivity and bespoke engineering of a specialist manufacturer.
The D5 Bi-Turbo is available through selected BMW dealerships, with both left- and right-hand drive versions to suit different markets. While pricing and UK availability were not specified at launch, Alpina models typically command a premium over the standard BMW 5 Series due to their exclusivity and engineering. Owners benefit from the support of BMW’s dealer network as well as Alpina’s reputation for quality and customer service.
Conclusion: A Distinctive Diesel Performer
The BMW Alpina D5 Bi-Turbo stands out as a distinctive option in the executive car market. By merging strong performance with diesel efficiency and the exclusivity of the Alpina brand, it appeals to drivers who cover long distances and do not want to compromise on pace or comfort. The D5 Bi-Turbo’s blend of power, refinement, and practicality makes it a compelling alternative to both high-performance petrol saloons and more conventional diesel models.
With its roots in motorsport-inspired engineering and a focus on real-world usability, the D5 Bi-Turbo continues Alpina’s tradition of producing distinctive, desirable cars for discerning enthusiasts. Whether chosen as a saloon or Touring estate, the D5 Bi-Turbo offers a rare combination of attributes that set it apart in a competitive segment.
