The new BMW ALPINA B4 Bi-Turbo model combine these characteristics like no other. The modern straight-six 3 litre engine equipped with two turbochargers produces 410hp and a maximum torque of 600Nm. The adaptive ALPINA sport suspension and the 8-Speed Sport-Automatic transmission with ALPINA SWITCH-TRONIC deliver maximum comfort and impressive dynamics. Functional aerodynamics, signature 20” ALPINA CLASSIC wheels and two elliptical double tailpipes are hallmarks of the ALPINA design philosophy.
