Alpina Adds 6-Series Based B6 Biturbo Coupe To Lineup

Follow Viknesh

Tired of waiting for BMW’s own M6 to arrive? Then perhaps you should give the guys at Alpina a call.

The German tuning firm--and a BMW specialist--has unveiled the follow up to the B6 Biturbo Convertible that we saw at the recent 2011 Frankfurt Auto Show, the all-new B6 Biturbo Coupe.

Based on the 2012 BMW 6-Series Coupe, the Alpina B6 Biturbo combines more potent performance with exclusive materials and unique styling.

Alpina's designers took one look at the 6-Series' twin-turbocharged 4.4-liter V-8 engine and decided that its 407 horsepower and 450 pound-feet of torque was simply not enough. Instead, they see a figure of 540 horsepower and 516 pound-feet of torque as being more appropriate for BMW’s big coupe.

Two turbochargers configured in parallel, each feeding one of the two cylinder banks with specially developed large diameter exhaust-turbines, allow this engine configuration to provide high power and torque over a broad rpm range while also maintaining good throttle response at lower revs.

Key features of the drivetrain include a custom intercooling system, MAHLE pistons and an Acrapovic titanium exhaust. ZF's latest eight-speed automatic transmission remains as standard though there are several updates to its software to ensure it works flawlessly with Alpina's new powerplant.

The end result of all this modification? Alpina promises 0-60 mph in just 4.4 seconds and a top speed of 200 mph.

But it’s not just about brute force. The Alpina B6 Biturbo Coupe also gets a custom suspension setup with electronically adjustable dampers and active roll stabilization as standard.

This system has been fully calibrated by Alpina and is tied into other system parameters controlling steering assistance, torque cushioning and stability and traction control. It allows the driver to choose from four different modes of performance: Comfort+, Comfort, Sport and Sport+.

Specific springs, increased front wheel camber and a subtle adjustment of the toe-in in addition to a 20-inch wheel and tire combination also aid handling.

To ensure the B6 Biturbo Coupe really stands out, Alpina’s design team decks out the car’s 6-Series donor body with several aerodynamic aids, hand-stitched leather trim, and an Alpina steering wheel.
