Alpina will be bringing the 2011 B5 Bi-Turbo Touring to the Geneva auto show next week for a debut.

The B5 Bi-Turbo Touring is the wagon variant of the B5 Bi-Turbo sedan model based on the (F10) BMW 5-Series.

Specs are expected to be the same as on the B5 Bi-Turbo sedan variant - a 4.4-liter V8 twin-turbo with an output of 507 PS (373 kW / 500 bhp) and 700 Nm (516 lb-ft) of torque. Transmission is the SWITCH-TRONIC eight-speed sport automatic gearbox from ZF.

Performance numbers are expected to stay the same too, although, Auto Bild reports a slightly slower 0 to 100 km/h (62 mph) sprint time of 4.8 seconds compared to the 4.7 seconds of the sedan variant. Top speed on the B5 Bi-Turbo is 307 km/h (191 mph) but Auto Bild reports this Touring will have a 300 km/h (186 mph) limit.

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

We expect more details to follow at the Geneva premiere.
