Finally, the 'D' BMW Alpina D3 in the Bi-Turbo stands for German "Drehmoment" or torque, the D3 has in abundance. A 450 Nm (332 lb.-ft.) of torque from 2000 to 2,500 rpm, the 2.0 liter four-cylinder D3 is operating in the territory of the V8 engine, or between the big guns of six-cylinder diesel engines. With the purchase of a D3 Bi-Turbo, Alpina has a client a combination of the motor drive is a delicacy rare and beautiful when compared to its competitors diesel.

The elegant way in which power is delivered can be further increased by SWITCH-TRONIC automatic extra. Developed by ZF and Alpina in a partnership, this sport-automatic is powered by three driving modes: D, S and M. According to the mood of the driver, he or she left a quarter of the automatic transmission, or shift manually using the buttons on the back of the wheel. This provides the broadest range of conduct fascination.

D3 Diesel Technology

Base D3 Bi-Turbo 2.0 is derived from the liter BMW four-cylinder, turbocharged diesel engine with all-aluminum block. High pressure 2000 bar Bosch Common Rail offers high efficiency by making use of piezo injectors. Two different sizes of exhaust-driven turbocharger, to breathe the D3 Bi-Turbo. A charger minor ticks will begin working immediately on a four-cylinder, and help restore an impressive 400 Nm of torque (295 pounds-ft) of torque at just 1,500 rpm. Maximum torque of 450 Nm (332 lb-ft) is achieved at 2000 rpm. About 3000 rpm onwards, a second, larger turbo, fully online, and then run the engine peak power is 214 horsepower (211 hp, 157 kW).

The configuration of the base engine, developed by BMW engineers in Steyr offers the opportunity to make the BMW Alpina D3 Bi-Turbo is a tremendously high specific power 107 hp per liter can.

The effective transfer of power

The six-speed manual gearbox allows the driver not only to test the 5200 rpm redline, but also to enjoy the driving experience in a way unprecedented for a diesel engine. Together with carefully calibrated spacing box, the torque curve can be used widely as possible a kind of unusual lightfooted forward progress, especially on winding roads.

At the request of many customers can now enjoy the D3 Bi-Turbo with the option SWITCH-TRONIC. This classic combination of plenty of torque and an automatic transmission offers the driver a high degree of flexibility.

Using the normal "D" drive, SWITCH-TRONIC moves up a gear more comfortable and driver almost unnoticed. "D" mode uses the engine's torque is impressive, driving style, which is very cheap. In the "S", time changes are then speed, and faster. This provides a driving performance that until now were found only in powerful gasoline engines.

The D3 Bi-Turbo only really becomes the "Diesel Sport" perfect even if the driver shifts manually using the shift buttons on the back of the wheel.

In addition, all measures to reduce CO2 emissions and fuel consumption for the base model, BMW moved to the D3, such as Auto-Start-Stop for models with manual transmission. High mileage drivers and business users will appreciate the resulting range: depending on driving style, up to 1,000 km (600 miles) is the norm.
