2012 BMW 6-Series Cabriolet by Alpina

The press days for the Frankfurt Motor Show have come and gone and Alpina , finally made the long awaited preview of their tuning program for the BMW 6-Series Convertible. .

Called the ’B6 Bi-Turbo Cabrio’, Alpina has improved the luxury cabriolet’s performance capabilities by adding its own twin-turbo system - hence the name - together with MAHLE pistons and a high-performance cooling system.

As a result, the 6-Series Convertible’s 4.4-liter V8 engine gained some significant ponies, pushing the standard output of 400 horsepower and 450 lb/ft of torque all the way up to 500 horsepower at 5,500 rpm and 516 lb/ft of torque between 3,000 and 4,750 rpm. Alpina also revised the gearbox on the car, putting in a new eight-speed automatic transmission.

Together with this revised gearbox, the 25% increase in output allows the Alpina-tuned ’B6 Bi-Turbo Cabrio’ to hit 0-62 mph in just 4.8 seconds (up from 4.9) with a top speed hitting an impressive 193 mph, a stark improvement from the standard model’s electronically limited top speed of 155 mph.

On top of that, the Alpina-tuned 6-Series Convertible averages 10.9 L/100km (25.9 mpg UK / 21.5 mpg US) and emits 255 g/km, impressive numbers for a car of this stature.

The car will make its official debut in Geneva next March, but at the very least, we’re getting a good idea on what Alpina has done to improve on the 6-Series Convertible’s already impressive performance capabilities.

It’s great that tuning company like Alpina modified the version of a certain vehicle for customer’s satisfaction! The Cabrio version on the 6-Series really makes quite elegant and luxurious! The increase on its top speed is awesome as well.
