เผยโฉม The new 2019 - 2020 BMW 7-Series โฉมใหม่ รุ่นไมเนอร์เชนจ์ เปิดตัว อย่างเป็นทางการในต่างประเทศ
BMW is sharpening the profile of its flagship models in the luxury segment.
The new edition of the BMW 7 Series makes a clear statement of intent with
its confident presence, sophisticated elegance and strikingly innovative
control/operation, driver assistance and connectivity technology.
The new exterior design of the luxury sedan showcases its prestige and status
more vividly than ever. And on the inside, sumptuous leather trim with
extended quilting and optimised acoustic comfort, not to mention the digital
display grouping of instrument cluster and Control Display, the
BMW Operating System 7.0 and the BMW Intelligent Personal Assistant, set
new benchmarks in wellbeing and comfort on the move.
The line-up of power units for the new BMW 7 Series has also been updated
and includes a new eight-cylinder engine, a six-cylinder in-line unit and plug-in
hybrid systems offering extended electric range. All of the model variants
already meet the stipulations of the Euro 6d-Temp emissions standard.
And the driver assistance systems now boast a broader range of functionality.
The latest advances towards automated driving are highlighted by technology
such as the new Reversing Assistant.
Powertrain: V12 with gasoline particulate filter, new V8, plug-in
hybrid models now with six-cylinder in-line engine.
The choice of power units for the new BMW 7 Series includes petrol and
diesel engines with six, eight and twelve cylinders, as well as an all-new plugin hybrid drive system. Topping the range is the 6.6-litre V12 engine at the
heart of the BMW M760Li xDrive, which produces 430 kW/585 hp (fuel
consumption combined: 12.5 – 12.4 l/100 km; 22.6 – 22.8 mpg imp; CO2
emissions combined: 285 – 282 g/km*) and now comes with a gasoline
particulate filter to minimise emissions. Meanwhile, the BMW 750i xDrive (fuel
consumption combined: 9.5 – 9.5 l/100 km; 29.7 – 29.7 mpg imp: CO2
emissions combined: 217 – 217 g/km*) and BMW 750Li xDrive (fuel
consumption combined: 9.6 – 9.5 l/100 km; 29.4 – 29.7 mpg imp; CO2
emissions combined: 218 – 218 g/km*) feature a newly developed V8 engine
with 4.4-litre displacement and maximum output raised by 60 kW/80 hp to
390 kW/530 hp.
The plug-in hybrid variants of the new BMW 7 Series take all of the luxury
sedan’s sporting prowess, passenger comfort and feel-good ambience and
combine them with exceptionally high efficiency and the ability to offer a virtually silent, all-electric driving experience with zero local emissions.
Their plug-in hybrid system now employs a specially adapted six-cylinder inline petrol engine and a more advanced high-voltage battery. As a result, the
system can unleash a combined output of 290 kW/394 hp with the Driving
Experience Control switch set to SPORT mode. The combined fuel
consumption of the BMW 745e, BMW 745Le and BMW 745 Le xDrive is
between 2.6 and 2.1 litres per 100 kilometres* (108.6 – 134.5 mpg imp), their
CO2 emissions are 59 – 48 grams per kilometre*, and combined electric
power consumption is 16.3 – 15.0 kWh per 100 kilometres*. The three
models achieve an electric range between 50 and 58 kilometres (31 – 36
miles).
Three highly efficient and low-emission six-cylinder in-line diesel engines,
each with 3.0-litre displacement and up to four turbochargers round off the
drive system line-up for the new BMW 7 Series. Delivering peerless
performance for a diesel-powered luxury-class car is the 294 kW/400 hp
engine under the bonnet of the BMW 750d xDrive (fuel consumption
combined: 6.0 – 5.8 l/100 km; CO2 emissions combined: 157 – 152 g/km*)
and BMW 750 Ld xDrive (fuel consumption combined: 6.1 – 5.9 l/100 km;
CO2 emissions combined: 160 – 155 g/km*). The power unit fitted in the
BMW 740d xDrive (fuel consumption combined: 6.0 – 5.6 l/100 km; CO2
emissions combined: 158 – 148 g/km*) and BMW 740Ld xDrive (fuel
consumption combined: 6.0 – 5.7 l/100 km; CO2 emissions combined: 158 –
149 g/km*) develops a maximum 235 kW/320 hp. And the 195 kW/265 hp
engine for the BMW 730d (fuel consumption combined: 5.5 – 5.3 l/100 km;
CO2 emissions combined: 144 – 138 g/km*), BMW 730Ld (fuel consumption
combined: 5.5 – 5.3 l/100 km; CO2 emissions combined: 145 – 139 g/km*),
BMW 730d xDrive (fuel consumption combined: 5.7 – 5.5 l/100 km; CO2
emissions combined: 150 – 143 g/km*) and BMW 730Ld xDrive (fuel
consumption combined: 5.8 – 5.6 l/100 km; CO2 emissions combined: 153 –
147 g/km*) represents the first step on the diesel ladder for
the new BMW 7 Series.
