Along with the flagship BMW 760i with 12-cylinder powerplant
and entry-level engine in the BMW 730i (not available in all markets),
customers can choose from a new six-cylinder in-line unit powering BMW 740i and
the V8 petrol engine in the 750i BMW revision. Six-cylinder diesel engine in
the BMW 730d and BMW 740d also offers drivers a combination of increased output
and lower fuel consumption. Make a debut, meanwhile, is the BMW 750d xDrive.
Under its hood lies a new TwinPower Turbo six-cylinder diesel engine - world's
most powerful diesel engine of its kind. Rounding range is the second
generation of BMW ActiveHybrid 7 with a new six-cylinder engine in-line and
significantly reduce emissions.
BMW V12 engine with TwinPower Turbo technology, gasoline
direct injection and continuously variable camshaft control is the top of the
range BMW 7-Series engine - no change there. All-aluminum powerplant generating
400 kW/544 hp output of 5972 cc displacement and peak torque of 750 Newton
makes meters (553 lb-ft) is available as a low self-esteem as 1,500 rpm. That's
enough to drive the BMW 760i is easy from 0 to 100 km / h (62 mph) in just 4.6
seconds and at an electronically limited top speed of 250 km / h (155 mph).
With a fuel economy average of 12.8 liters per 100 kilometers (22.1 mpg) and
CO2 emissions of 299 g / km, is the most civilized traders achieve
unprecedented efficiency to the output class.
Revised V8 petrol engine under the bonnet of the BMW 750i makes its debut. 4395 cc eight-cylinder powerplant to maintain collateral impressive power delivery is smooth and vibrant pre-update today. However, the optimized high-pressure direct injection and loss of reduced cycle costs - thanks in main to seamlessly control variable intake valve lift - has pushed the performance potential for a higher level than its predecessor and substantially reduces fuel economy and emissions. In the latest development stage, the engine produces 330 kW/450 hp peak output (+ 10%) and released a peak torque of 650 Newton meters / £ 479-ft (+ 8.5%) between 2,000 and 4,500 rpm. Tim engine with eight-speed automatic transmission, which allows the BMW 750i to sprint from 0 to 100 km / h (62 mph) in just 4.8 seconds and progress to a top speed electronically governed from 250 km / h (155 mph). Eight-cylinder engine with improved performance belies a better efficiency than ever before, with overall fuel consumption of 8.6 liters per 100 kilometers (32.9 mpg) and CO2 emissions amounted to 199 g / km, the BMW 750i beat its predecessor less obviously a strong by 25 percent. In China market, the BMW 750i is powered by a 4-liter engine variant offers 300 kW/408 hp and 600 Newton meters (443 lb-ft) of torque.
The 3-liter six-cylinder in-line engine with great force and prominent unrivaled high-revving character. Powerplant state-of-the-art is one of the first wave of highly efficient gasoline engine to bring together technology BMW TwinPower Turbo with High Precision Direct Injection Gasoline, twin-scroll turbocharging, Double-VANOS camshaft and the time variable Valvetronic variable valve timing. The peak output of 235 kW/320 hp and 450 Newton-meter maximum (332 lb-ft) of torque on tap as low down as 1300 rpm to make ultra-smooth engine performance equal of the BMW 740i out. However, fuel economy in the EU test cycle is an impressive 7.9 liters per 100 kilometers (35.8 mpg) while CO2 emissions of 184 grams per kilometer is 21 percent decline in output of its predecessor's.
It's proven 3-liter straight six petrol engine developing, as before, 190 kW/258 hp and maximum torque of 310 Newton meters (229 lb-ft) at 2600 rpm. Connect with the new eight-speed automatic transmission allows the BMW 730i to exploit additional fuel-saving potential; fuel economy average is at 8.6 liters per 100 km (32.9 mpg) while CO2 emissions of 199 grams per kilometer is 13 percent below the levels recorded by his predecessor to work with six-speed transmission.
Brand-new top-of-the-line diesel powerplant under the hood of the BMW 750d xDrive provides fresh evidence of BMW's pre-eminence in the field of engine technology. World's most powerful six-cylinder in-line diesel engine seized headlines with innovative technology and unique, and imbues luxury sedan with impressive dynamics and outstanding efficiency.
TwinPower Turbo Technology superb six-cylinder unit in the heart of working with three turbocharger and injection system was further developed common rail for the first time in order to optimize engine output, torque and responsiveness. Precisely coordinated management of the turbocharger ensures that high-performance 3-liter diesel engine developing attraction force across the full rev range - and all with a very high level of efficiency. Chargers first started working just over idle so that the combustion chamber can be provided at an early stage. At 1,500 rpm high-pressure turbo bigger kick to help the engine reach maximum torque. Finally, a third turbocharger joins the fray at 2700 rpm and ensures impressive power delivery to maximum revs achieved. Piezo injector squirts fuel into the combustion chamber up to 2200 bar, with three pre-injection, main injection and a four post-injection of fuel during each step to ensure the efficient and clean burning.
Further development of the stringent BMW TwinPower Turbo technology has also given the dynamics and efficiency of the familiar six-cylinder in-line diesel engine boost. At 230 kW/313 hp, maximum output diesel 3-liter six-cylinder is a five-kilowatt higher than its predecessor, while peak torque of 630 Newton meters / 465 lb-ft (+ 30 Nm / 22 lb-ft) at 1,500 rpm comes operate. Added to that, the response sharpens thermodynamic optimisations diesel models and improve agility. Connect with the new eight-speed automatic transmission, more powerful BMW 740d managed to record the fuel consumption is even lower than 5.7 liters per 100 kilometers (49.6 mpg) to go with CO2 emissions of 149 g / km. That is an increase of 17 percent on its predecessor.
Another round of fuel consumption and emissions reductions BMW 730d see the building on its position as the most economical luxury sedan in the world with the lowest emissions. The peak output of a 3-liter six-cylinder diesel, which reflects that in the BMW 740d engine construction, has increased by 10 kilowatts to 190 kW/258 hp. And maximum torque is also increased to 560 Newton meters / 413 lb-ft (+ 20 Nm / 15 lb-ft). However, fuel economy average of 5.6 liters per 100 kilometers (50.4 mpg) in the EU test cycle and CO2 emissions of just 148 g / km allows to outperform its predecessor - married with six-speed automatic transmission - by 17 percent. Determine the machine with optional BluePerformance technology available to complete to meet the EU6 standard.
BMW xDrive intelligent all-wheel drive make the new BMW 7-Series sedan even more attractive proposition. In addition to typical benefits of all-wheel drive, electronically controlled xDrive system - which can vary the power distribution between front and rear wheels with split-second speed - ensuring top class traction, safety and handling, and optimal power management any weather and road conditions. This system has been established to provide greater agility and precision through corners as well, offering the ideal combination of dynamism and comfort, and provides an excellent basis for a smooth driving experience.
As BMW continues to push forward with the development of intelligent hybrid propulsion system, the second generation of BMW ActiveHybrid 7 is set to celebrate the premiere in 2012. Updated model sets itself apart with lower fuel consumption and emissions, as well as innovative additional functions. The latest evolutionary stage in-line six-cylinder engine featuring an impressive high-revving characteristics, torque and efficiency. Leading petrol engine with BMW TwinPower Turbo technology is 235 kW/320 hp variant of the units installed in the new BMW 740i and replace the eight-cylinder engine used until now. Other hybrid components including the 40 kW/55 hp synchronous electric motors, hybrid-spec eight-speed automatic transmission, a high lithium-ion battery performance and power electronics that support intelligent energy management. The various components together into a strong unity and harmony, giving BMW ActiveHybrid 7 incredible dynamics and the balance between performance and fuel economy - and not just in relation to its predecessor.
With 260 kW/354 hp system output and peak torque of 500 Newton meters (369 lb-ft), BMW ActiveHybrid 7 accelerates from 0 to 100 km / h (62 mph) in just 5.7 seconds. At the same time, posting sedan fuel economy average of 6.8 liters per 100 kilometers (41.5 mpg) and CO2 emissions of 158 g / km. That means a more powerful hybrid technology uses fuel approximately 14 percent less than the BMW 740i with a conventional drive system.
