Alpina have made a habit of giving BMWs more power. Previously seen with their takes on the BMW B6, B5 and 7-Series sedan, the German tuners have gotten their twin-turbocharging hands on a 2012 BMW diesel 5-Series. The biturbo system complements the car's stock diesel 3.0-liter direct-fuel injection 6-cylinder common-rail engine. The engine is mated to a Switch-Tronic 8-speed Sport Automatic Transmission that features three distinct driving modes: Automatic Shift Mode, Manual Shift Mode and Sport Shift Mode.

The new system boosts power on the D5 sedan 105hp to a respectable 350hp. Even with the added power boost, Alpina has somehow managed to keep the sedan at the same fuel consumption and emission figures at the same level. The performance numbers on Alpina's BMW are pretty good, as the sedan is able to hit a top speed of 168mph and can sprint from 0-62mph in 5.2 seconds. Alpina's BMW also features some new equipment, including an enhanced chassis and high-performance brakes to handle all the added power. It sits on a set of classic Alpina 20-inch wheels.
