The new Diesel Bi-Turbo BMW Alpina D3 continues the story of success started in 2006 by the popular 200 hp (147 kW) Alpina sport diesel model, with over 850 units sold since its launch. This response is more feasible for low emissions and consumption discussions of current times, and in perfect harmony with the price of fuel out of hand.
The designation "D" indicates unequivocally that the diesel engines in the Alpine family. "D" is particularly dynamic. The new D3 Bi-Turbo, to celebrate its world debut at the Geneva Motor Show 2008, car-214 HP/211 HP (157 kW) @ 4100 rpm - a diesel engine is exceptionally powerful speed and highly unusual . 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). Thanks to extensive development work, the optimal mapping of turbochargers, fuel injection system, the new D3 Bi-Turbo can speed up to 5200 rpm, where most diesel aggregates today it stops at 4500 rpm.
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. Lightning-fast switching is the agenda - even the best drivers can not go faster than them. This is revealed in an impressive performance numbers for both transmissions The manual D3 Coupé reaches 100 km / h [62 kmh] in 6.9 seconds (7.0 seconds automatic), with a top speed of 244 km / h [ 152 km / h].
In particular, given the current discourse of CO2, the fuel figures of the BMW Alpina D3 Bi-Turbo Coupe economy for the EU combined cycle 5.4 (5.6) l/100 km [52.3 Imp Gal (50.4) ], and the resulting CO2 emissions of just 143 (148) g / km, Alpina reveals the efforts of the maximum fuel efficiency. 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.
Alpina suspension, tires and wheels
BMW Alpina D3 Bi-Turbo Coupe uses suspension technology quite similar to the BMW Alpina B3 Bi-Turbo, a car whose suspension and chassis set-up has received rave reviews from the press. BMW 3-Series Coupe high chassis rigidity and five-link rear suspension fitted Alpina great potential for the highest levels of driving dynamics. The calibration leg / spring sports is very appropriate, for the character D3. Thank you to its light weight, extremely agile driving characteristics achieved, which is in the form of excellent handling, all the way to the border.
Standard tires and weight-optimized 18 "Alpina Classic alloy wheels can be ranked up with optional 19" wheel / tire combination, available in Classic or the Alpina Dynamic wheels design. 245/40 ZR18 tires interaction with 265/40 ZR18 tires in front and rear ride 8x18 "and 9x18 in the face" to the rear wheels, producing an incredibly accurate reading. Even more important is the choice not to use heavy Run-Flat technology, Alpina tire, for reasons of weight and comfort.
In conclusion
Alpina interior design elements show typical Alpine Coupe BMW D3 Bi-Turbo individuality and elegance. Attractive alloy wheels, instrument cluster with blue rings and a sports leather steering wheel with Alpina emblem, multi-functionality (automatic transmission) is standard on the D3 Bi-Turbo. The front spoiler reduces lift lines cut and highlights the aesthetic, which can be further increased with an optional rear spoiler.
