ALPINA unveiled the 2011 B5 BiTurbo Touring at the 2011 Geneva Motor Show. 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 offers 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. ALPINA also displayed the sedan version of the same B5 BiTurbo at the show.
