معرفی خودرو
ب ام و سری7 (730li) فول سایز ترین و مجلل ترین سدان خودروساز باواریایی (BMW) محسوب می شود که به جهت داشتن موتور 4 سیلندر در لیست پیشرانه های موجود برای سفارش، بعد از قانون منع ورود خودروهای بالای 2500 سی سی توانست پای خود را به بازار کشور باز کند و در شرایطی که رقبا امکان حضور را نداشتند به خوبی در بازه ی قیمتی خودرو های لوکس یکه تازی کند. البته پس از وضع قانون جدید منع ورود خودرو های بالای 40 هزار دلار درب های گمرک بر روی BMW 730li نیز بسته شد.
دو کد اتاق مختلف G11 و G12 برای سری 7 ب ام و وجود دارد و همانطور که انتظار می رود یک کد فاصله محوری طویل تری دارد (G12) و همین مدل نیز در ایران عرضه شده است. 730 علیرغم موتور کم حجم (2لیتری) بسیار فراتر از انتظار عمل میکند و با انتقال حدود 250 اسب بخار توسط جعبه دنده 8 سرعته به چرخ های عقب، به راحتی انتظارات راننده را برای شتابگیری برآورده می کند؛ هرچند باز هم نمی توان انتظار یک خودروی 8 سیلندر را از آن داشت.
BMW 7-Series
The 2018 BMW 7 Series comes with more semi-autonomous driving features than before. Otherwise, the BMW 7 Series carries over unchanged for the 2018 model year. 2016 brought an engineering leap, perfecting the balance at 50/50 and saving weight by using tricks from the i electric car: carbon fiber in the chassis, and aluminum in the doors, trunk lid and suspension.
The 7 Series cars are sporty and comfortable to drive. Some models are available with rear-wheel drive or all-wheel drive.
The BMW 740i uses a twin-turbocharged 3.0-liter inline-6 making 320 horsepower, a sweet engine. The BMW 750i packs a 4.4-liter twin-turbocharged V8 making 445 horsepower, mated to a silky 8-speed automatic transmission, pulling zero to sixty in 4.3 seconds.
There’s also a new 740e plug-in hybrid that mates a 2.0-liter turbocharged four-cylinder with a 9.2-kilowatt hour battery to get a total of 322 horsepower. All-wheel-drive is standard. We’ve found the 740e to be very relaxed because the hybrid system is seamless. But it’s burdened by additional weight of about 400 pounds. BMW says it can travel 23 miles on all-electric power.
The Alpina B7 xDrive uses the 4.4-liter V8, and is fitted with Integral Active Steering that combines variable-ratio electric steering at the front axle with active steering on the rear axle. This helps to blast the Alpina from zero to sixty in a supercar-like 3.6 seconds.
With its V12 engine, the M760i xDrive is nearly as quick, with zero to sixty performance of 3.9 seconds. The twin-turbo V12 makes an awesome 600 horsepower and 590 pound-feet of torque.
On all models, Driving Dynamics Control sets the steering, throttle, shock absorbers and transmission, to three modes: Sport, Comfort and Comfort Plus. A complex system called Active Comfort Drive with Road Preview adds anticipatory functions to the active chassis with air suspension, while the Integral Active Steering (variable-ratio rear-wheel steering) now comes with all-wheel drive. The automatic transmission downshifts on its own, based on what the navigation system tells the transmission about the road ahead, for example a hill.
The 740i gets an EPA-rated 23 Combined miles per gallon with all-wheel drive, or 24 Combined mpg with rwd. The 750i gets 19 Combined mpg with awd, 20 mpg with rwd. The 740e gets 27 Combined miles per gallon, using all of its 23 miles of electric range.
The 7 Series hasn’t been crash-tested because it’s a low-volume product. Standard safety equipment is bountiful, from active headlamps to active headrests to rearview camera. Optional safety equipment includes everything from night vision to a watchdog sensor that flashes a coffee cup if it sees you getting tired.
Driver Assistance Plus Package II includes adaptive cruise control, active lane-keep assist, Side Collision Avoidance, and Traffic Jam Assistant. It provides semi-autonomous driving, following cars ahead and providing steering assistance to keep the car in its lane.

Interior
Now it’s the cabin’s turn to push boundaries, by maximizing and exaggerating BMW design themes, taking ideas from the futuristic i8. The instrument panel is like a horizontal shelf, its formality enforced by satin-metallic brightwork on the knobs, many of which change temperatures for the comfort of your fingertips. It might be called retro-futurism. You’ll want to linger there.
The corners are pushed outward to make more space in the cabin, and the rear is limo-like, luxurious for two (who might be optionally ventilated and massaged), but room for three. Superb front seats hit the sweet spot between comfort during hours in the saddle, and support in the twisties.
The interior wood and diamond-stitched leather is the highest quality, as expected from BMW. Heated armrests, front and rear. Ambient carpet lighting standard. Fragrance is available, under a panoramic LED roof.
Although late to the theater, BMW does touchscreen now, to the max. The iDrive 5.0 uses a 12.3-inch landscape-oriented screen. Still, some people don’t like all those finger-smudges a touchscreen collects. So on the 7 Series there is also the familiar iDrive controller, now with a handwriting touchpad (also steering-wheel controls and voice recognition).
More futuristically, iDrive also now has Gesture Control. There’s a 3D sensor in the iDrive knob, and you just flash the sensor one of five hand signals, to get the sound system volume raised or lowered, answer or don’t answer the phone, or browse a 360-degree of the cabin. The system is a bit slow.
The Bowers & Wilkins surround sound is certainly not dull, with 1400 watts and 16 speakers. Nor is the head-up display. The standard Adaptive Headlamps don’t just turn with the car, they consider speed, steering angle and yaw.
