BMW B6 Biturbo Coupe

If you can’t wait for BMW to get their act together and bring out an M6, get in touch with Alpina, who have today unveiled their B6 Biturbo Coupe as a follow-up to the convertible from Frankfurt. Its twin-turbocharged 4.4-liter V8 now produces 533hp and 516lb-ft of torque, sprints from 0-62mph in 4.4 seconds and hits a top speed of 197mph. This extra power and torque can be provided over a broad rpm range as the two turbochargers have been configured in parallel, each feeding one of the two cylinder banks. A collaboration with transmission specialist ZF resulted in an eight-speed sport automatic transmission featuring a limited-slip rear differential, and another collaborative effort, this time with Akrapovic, concluded with a lightweight titanium exhaust system replacing the twice-as-heavy stainless steel version. Electronically adjustable dampers and active roll stabilization comes as standard and four modes of performance - Comfort, Comfort +, Sport, and Sport + - can be selected. As for the body, Alpina’s design team have applied several aerodynamic and handling aids to the 6-Series donor body. These include an integrated carbon-fiber splitter, 20-inch alloys, and a dramatic wing to replace the rear spoiler. Hand-stitched leather trim and an Alpina steering wheel are highlights of the interior enhancements. The upgraded 533hp engine now also sits in the B6 Cabriolet.
