New Alpina B6 Bi-Turbo with 507HP

For more than four decades now, German tuning house Alpina has been modifying BMWs cars. The Bavarian luxury carmaker has a tight relationship with the tuner going as far distributing the high-performance models through its official network.
Alpina's newest creation is the B6 Bi-Turbo Cabrio based on the latest 6-Series Convertible, which will make its world premiere at the rapidly approaching Frankfurt auto show on September 13.
At the heart of the Alpina B6 Bi-Turbo Cabrio is specially modified 4.4-liter twin-turbocharged V8 engine capable of delivering 507-horsepower and a monstrous 700Nm (516.3 lb-ft) of peak torque delivered between 3,000 and 4,750 rpm.
Power is channeled to the rear wheels through an eight-speed automatic Switch Tronic transmission, with Alpina claiming 0-100km/h (62mph) sprint time of 4.8 seconds and a top speed of 311km/h (193mph) with a combined fuel consumption of 10.9lt/100km (21.6mpg US) for the Convertible model.
In comparison, the factory 650i Convertible features a 4.4-liter turbo V8 producing 407HP and 600Nm / 443 lb-ft. It completes the standard sprint in 5.0 seconds while reaching an electronically limited top speed of 250 km/h (155 mph), and returning an average fuel consumption of 10.7lt/100km.
Along with the powertrain modifications, the Alpina flavored 6-Series Convertible gains the tuner's trademark multispoke alloy wheels plus carbon fibre trim bits, front apron and rear spoiler as well as bespoke interior parts.
The B6 Bi-Turbo Cabrio model will soon be followed up by the coupe derivative.

New Alpina B5 Bi-Turbo Based on 2011 5-Series

Independent BMW customizer Alpina has published the first official sketch of its upcoming B5 Bi-Turbo ahead of the sports saloon world premiere at next month's 'Goodwood Festival of Speed' event in the UK.As the car's name suggests, the B5 Bi-Turbo is based on the new 2011 BMW 5-Series sedan. So far, Alpina is keeping a tight lid on details about the car, but if the company's previous and current models are anything to go by, then the B5 Bi-Turbo could be all the M5 you'll ever want.
We wouldn't be surprised if the new B5 uses the same twin-turbocharged 4.4-liter V8 engine with an output of 500-horsepower and a hefty 516 lb-ft (700Nm) of torque found under the bonnet of Alpina's 7-Series B7 Bi-Turbo.
Engine aside, the sketch shows that the B5 will be mildly dressed up with a new body kit comprising of a front lip spoiler and rocker panels, as well a set of larger multispoke wheels. Interior upgrades also expected to be part of the package.
