BMW Alpina B6 Bi-Turbo Cabrio released image

BMW tuning specialist Alpina is currently doing what the Bavarian automaker should have done in the first place, help a powerful version of the 6-Series under its B6 Bi-Turbo Cabrio name, which seems like a good alternative until the real M6 gets here.

The new Alpina B6 Bi-Turbo Cabrio takes its power from BMW’s 4.4 liter V8 unit with new twin-turbines from the BMW tuning specialist, boosting its power up to 507 horsepower at 5.500 rpm, while the torque reaches 700 Nm or 516 lb-ft, delivered between 3.000 and 4.750 rpm.

According to Alpina, the B6 drop-top can accelerate from 0 to 100 km/h in just 4.8 seconds reaching a top speed of 311 km/h or 193 mph, all of this with a combined fuel consumption of 10.9 liters per 100 kilometers and CO2 emissions of 255g/km.

You would think that the new B6 Bi-Turbo Cabrio will make its official debut at the upcoming Frankfurt Motor Show, you’re wrong. The latest creation signed by Alpina will be unveiled at the next year’s Geneva Auto Show.
