Alpina reveals details of 608ps, 800Nm V8-powered anniversary Edition 50 range
To mark the bespoke manufacturer’s half centenary, Alpina will create 100 vehicles, powered by heavily revised BMW 4.4-liter V8 engines. The Edition 50 range will be the most powerful roadcar in the company’s history
To mark its half century this year, bespoke car manufacturer Alpina will create 50 saloons and 50 coupes to celebrate the milestone. Based on the B5 Bi-Turbo (saloon) and the B6 Bi-Turbo (coupe), each vehicle will include a heavily revised V8 powerplant that will propel the luxury five seater from 0-100km/h in 4.2 seconds, and on to a top speed of 328km/h. Alpina’s 50-year heritage has been marked by the creation of a number of highly-regarded luxury performance road cars and iconic race cars – including the BMW 3.0 CSL.
With an astonishing 800Nm and 608ps, Edition 50 is the most powerful road car ever developed by the German company. Alpina’s 70-strong engineering team has also managed to marry these performance specs with a fuel economy (on the most representative combined cycle) of 9.5l/100km and best in-class CO2 emissions of 221g/km.
“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-liter 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. Many other engine components have also been optimized for high performance with long life, including new lightweight pistons designed to accommodate the high thermal loads of prolonged high-performance driving.
Compared with the standard B5 Bi-Turbo, further optimization of the induction system, a high-capacity fuel system and other unique upgrades have released an additional 70Nm and 61ps for the Edition 50. Like all new Alpina vehicles, the car will be supplied with a two year BMW-endorsed warranty.
