Alpina has unveiled the new B5 BiTurbo Coupe at the Tokyo Motor Show with first cars reaching showrooms in May 2014.
Based on the new BMW 4 Series, the B5 BiTurbo Coupe is powered by an updated twin-turbocharged 3.0-litre straight-six petrol engine that produces 404bhp and 443 lb ft of torque and is linked to a 8-Speed Sport-Automatic transmission with ALPINA SWITCH-TRONIC.
The B4 BiTurbo Coupe accelerates from 0-62mph in just 4.2 seconds and the top speed is 190 mph.
Other under the skin updates compared to the standard 4 Series include adaptive ALPINA sport suspension and high-performance braking system with discs that measure 370mm front and 345mm rear.
Visually the B4 is distinguished from the standard 4 Series with front and rear spoilers, signature 20-inch ALPINA CLASSIC wheels wrapped with non run-flat Michelin Pilot Super Sport tyres and two elliptical double tailpipes on both sides.
Interior updates include Lavalina leather upholstery, special floor mats and Alpina badging.
The B4 will be also available with all-wheel drive on selected markets, but not very likely in UK.
UK pricing is expected to start from around £60k.
2013 was a record year for Alpina, as they sold 1400 cars globally and 300 in Japan.
