The BMW Alpina B4 Biturbo, a product of the longstanding collaboration between BMW and Alpina, exemplifies the synthesis of performance and luxury in the automotive realm. Based on the BMW 4 Series, the Alpina B4 Biturbo undergoes meticulous enhancements by Alpina, a Bavarian tuning company officially recognized by BMW. The heart of this high-performance coupe lies in its engine – a 3.0-liter twin-turbocharged inline-six powerplant meticulously tuned by Alpina engineers. This results in an impressive power output of 404 horsepower and 600 Newton-meters of torque, seamlessly transmitted to the rear wheels through an eight-speed automatic transmission.

The Alpina touch extends beyond the powertrain, encompassing meticulous chassis tuning and aerodynamic enhancements. Alpina’s attention to detail is evident in the bespoke Alpina Classic 20-inch wheels, the signature pinstripes on the bodywork, and the subtle yet purposeful aerodynamic elements. The interior of the B4 Biturbo reflects the collaboration’s commitment to luxury, with handcrafted materials, personalized Alpina touches, and advanced infotainment systems. This unique blend of high-performance engineering and refined craftsmanship positions the BMW Alpina B4 Biturbo as a distinguished member of the Alpina lineup, appealing to enthusiasts who seek a harmonious fusion of power, precision, and luxury in a sporty coupe.
