Alpina, a well-known BMW tuner, will debut its version of the twin-turbo V-8-powered 650i Convertible at this year’s Frankfurt Motor Show. If what Autocar reports is true, expect the finished product to be the next-best thing until BMW itself launches an M6 convertible.
The German tuning house has historically turned BMWs into more potent, not to mention more exclusive, driving machines. The Alpina treatment typically consists of adding more power, unique bodywork, suspension enhancements, and the firm’s characteristic multi-spoke alloy wheels to an existing BMW model. If the last Alpina B6 is any indication, we can expect the 2012 model to follow those same, tried-and-true traditions.
The B6 will reportedly debut with a tuned twin-turbo 4.4-liter V-8, producing up to 500 hp and 516 lb-ft of torque. If that’s the case, power for Alpina’s modified 6 Series Convertible would be up 100 hp and 66 lb-ft from the standard model BMW sells. Autocar says the B6 Bi-Turbo will hit 62 mph from a standstill in 4.8 seconds, and will top out at 193 mph.
For full details on Alpina’s latest super Bimmer, we’ll have to wait for its unveiling at the Frankfurt show next week.
