Alpina has presented the all-new 2014 B4 Bi-Turbo based on the recently announced BMW 4-Series Coupe 335i.

The sports coupe comes with a lot of unique features like an aerodynamics package from Alpina, new wheels and improved interior.

The exterior boasts a new front apron and rear spoiler. There is also a set of 20" ALPINA Classic wheels fitted with ultra-low profile tires. At the rear we can see ALPINA lettering and signature twin tailpipes.

The engine is the well-known 3.0 liter straight-six – 410HP (301 kW) at 5,500RPM and 600Nm (444 lb-ft) at 3,000RPM. The engine is connected to a ZF 8-Speed Sport-Automatic transmission. 0-100 km/h in 4.2 seconds and a top speed of 305 km/h (188 mph). Furthermore, the new B4 Bi-Turbo Coupe achieves a class-leading combined fuel economy of just 7.6l/100km and 177g/km CO2.

The suspension set-up of the new B4 Bi-Turbo provides great ride-quality and comfort while simultaneously offering sharp and dynamic handling. The adaptive ALPINA sport suspension solves this conflict of interest by means of electronically adjustable dampers in collaboration with performance springs, bump stops and stabilisers. The system allows the driver to use the Drive Performance Control (Eco Pro, Comfort, Sport, Sport+) to select the suspension setting and driving dynamics to match his mood.

Last, but not least is the high-performance brake system - 370mm discs at the front and 345mm discs at the rear with 4- and 2-piston calipers, respectively.
