Bespoke car manufacturer ALPINA will create 50 remarkable saloons and estates as well as a further 50 similar coupes to celebrate the company’s half century this year.
Based on the B5 Bi-Turbo and the B6 Bi-Turbo respectively, each vehicle will include hand-crafted Edition 50 body and trim features and a remarkable, heavily revised V8 that will propel the luxury five seater from 0-100 km/h (62 mph) in 4.2 seconds and on to a top speed of 204 mph. It makes 591 horsepower and 590 pound-feet of torque, a bump of 59 hp and 52 lb-ft from the regular versions, Edition 50 is the most powerful road car ever developed by the German company.
“Edition 50 is the ultimate expression of the ALPINA values,” explains ALPINA GB brand manager Matthew Stripling. “It combines very high levels of long-term comfort with superb performance that is available from low engine speeds, making it effortlessly fast. Add the deep base soundtrack and the feeling of bespoke luxury, and you have a highly engaging car that offers a unique set of attributes for the discerning enthusiast.”
Based on BMW’s proven 4.4 ltr V8, the B5 Bi-Turbo’s heavily-revised engine uses two ALPINA-specific turbochargers located between the cylinder banks, operating in parallel, delivering up to 1.2 bar. Particular attention has been paid to air flow optimization, with short intake paths and optimized radii to allow near-instantaneous throttle response. Charge density and thermal stability are further enhanced by a combination of a large-volume air-cooled intercooler behind the bespoke front spoiler with two smaller, ALPINA-developed water-cooled intercoolers close coupled to the turbochargers. A large-capacity oil radiator and supplementary coolant radiator, also mounted behind the front spoiler, further improve thermal stability.
Beyond just the major improvement in power, these special vehicles wear Alpina’s more aggressive, though still understated body kit. They also ride on an updated version of the company’s famous wheels that feature added side cuts on the multiple spokes to reduce weight.
The light-weight titanium exhaust system, developed with specialist supplier Akrapovic, improves throttle response by minimizing back pressure and saves a further 17 kg compared with a stainless steel system. A limited slip differential is also standard, as are subtle aerodynamic enhancements developed in BMW’s wind tunnel.
Each car will be available in ALPINA Green or ALPINA Blue, or in a bespoke Edition 50 Sepia.
