Alpina B6 Bi-Turbo Cabrio Image and Specs Released

A lot of people admire the new BMW 6 Series Convertible and many of them would love to receive an M version of the car. BMW is probably working on that, but what do we do until it arrives?

Well, one answer would be to trade aggression for power&refinement and turn to official BMW tuning specialist Alpina, which is currently making efforts to turn the 650i Convertible into the B6 Bi-Turbo Cabrio, a creation that should be a true delight for its owner.

In the transformation process, BMW's 4.4-liter V8 looses its factory stock twin-turbines and gains new ones from Alpina. Thus, the power climbs to 507 hp, which arrive at 5,500 rpm, while torque reaches 516 lb-ft (700 Nm), which are delivered between 3,000 and 4,750 rpm.

This allows the drop-top Alpina to complete the 0 to 62 mph sprint to 4.8 seconds and, if the driver insists, the speedometer will eventually show 193 mph (311 km/h).

However, Alpina promises that the fuel efficiency won't be affected by the extra muscle. To be more precise, the aftermarket developer claims that you'll receive 10.9 liters per 100 km, while the CO2 emissions reach 255 grams per km.

However, according to Auto Motor und Sport, the B6 Bi-Turbo Cabrio isn't expected to arrive until next year's Geneva Auto Show, which means that you still have a long way to go if you want one of these in your garage.
