Next week at the 2011 Geneva Motor Show, ALPINA will unveil to the world the 2011 B5 BiTurbo Touring. The B5 BiTurbo Touring is the wagon variant of the B5 BiTurbo sedan model based on the new BMW 5 Series.

The B5 Biturbo Wagon will offer the same powertrain as the sedan, 507 horsepower and 700 Nm of torque from a twin-turbocharged 4.4 liter V8 unit, mated to a SWITCH-TRONIC eight-speed sport automatic gearbox from ZF.

Not yet confirmed, but the expectations are that the B5 Wagon will sprint to 62 mph in 4.8 seconds with a top speed of 187 mph (301 km/h). In comparison, the sedan version needs 4.7 seconds to reach the same speed.

ALPINA’s website says the B5 Touring is “the finely honed balance between athleticism, comfort and every-day luxury that has defined ALPINA automobiles for decades”.

“Five different generations of 5 Series-based ALPINA automobiles have been developed in the last 35 years, revealing to those in the know a unique and exclusive driving experience. The sixth generation draws from the finest ingredients of past generations to offer a mouth-watering driving experience for the most demanding drivers of high performance luxury cars”, a similar statement said on the website.

Fuel-economy will be 10.9 liters/100 km compared to 10.8 for the sedan.

Full details and photos will be released prior to the Geneva Auto Show.
