Official details have been released of the new Alpina B5 Bi-Turbo which is based on the current F10 5-Series and occasionally called the M5-killer.The engine as mentioned before, will produce 507hp from just 5,500rpm coming from an aluminium V8 twin turbo 4.4-litre engine. This also produces a humongous 700Nm of torque from as low down as 3,000rpm.

The Alpina has also optimised the intake air cooling system with shorter intake tracts and increased intercooler flow. Apart from that, high performance pistons along with direct injection and Double VANOS give it a more efficient drive train returning 10.8L/100km while only producing only 252g/km of CO2.

This power is transmitted through the SWITCH-TRONIC 8-speed sports automatic transmission which changes its character when in sports mode, while the manual mode gives customers full control over every shift. Handling all this power will be the suspension set-up which has been specifically tuned to be comfortable yet precise around corners. This has been done with the use of progressive springs and special suspension arms sitting on light-weight 20″ ALPINA classics.

Helping with the handling will be the new aerodynamic package which now reduces lift when travelling at high speeds by 60 percent in the front and 30 percent in the rear, providing excellent stability when needed. Apart from that it features the F10’s new sleeker more sporty body style.

Moving on inside, the B5 will feature leather upholstery, navigation system, LAVALINA leather SWITCH-TRONIC steering wheel and Bluetooth compatibility. This is nicely complemented by the ALPINA burled Myrtle wood trim giving it that all important ambience.
