About the Alpina B5 GT G30
The Alpina B5 GT serves as the final, high-performance farewell to the G30-generation 5 Series and the Buchloe firm's independence before its full integration into the BMW Group. It features a modified version of the N63 V8, producing 634 PS, making it the most powerful engine in Alpina's history. Beyond the raw power, the GT is distinguished by its unique 20-inch Classic forged wheels in Marron Volciano, front dive planes, and a bespoke titanium nitride-coated quad exhaust system. It offers a more refined, long-distance alternative to the BMW M5 CS, blending supercar-rivalling speed with traditional Alpina luxury and composure.
