Responding to the real name of prototypes, the vehicles we have tried and are still disguised forms appear disguised as stickers. Also, it will have to wait a few weeks to acknowledge the work of designer Karim Habib team. Unlike the E65 series that had wiped casts a new design language supported by designer Chris Bangle and long scorned, this 7 Series seems to evolve smoothly and found the proportions of the current model. Tim Resch, head of the program, however, let go a few indiscretions. “This new 7 Series ends the race for size and gauge remains substantially that of the current model.” Is that now the priorities are focused on the reduction of CO2 emissions and the maturity of 95 g / km in 2021. As much to contribute to the reduction in average CO2 range as to comply with the DNA the brand that puts the “fun to drive” at the forefront, BMW engineers have worked to heal the line of the new 7 Series.
Carbon in a lightweight construction services
This will make noise, the latter vessel Bavarian won 130 pounds on the scale through the use of technical solutions developed for the BMW i family. While some competitors utilize aluminum to shed pounds, like the Audi A8 and Jaguar XJ, the 7 Series is the first car in its segment to use carbon. Experience with some models M who received a carbon roof and designed i3 and i8 contributed to propose a new lightweight design. Engineers still preserve the secrecy of the production method of the “Carbon Core” but BMW has obviously found a technical and industrial solution to combine several materials, reinforced plastic carbon fiber (CFRP), aluminum, steel and plastic. Depending on location, BMW employs different structures: braided carbon or recycled carbon. Engineers have been especially carbon in places where gains were the most sensitive, without degrading the strength, comfort and acoustics. The bare drum has lost weight by 40 pounds compared to the current model thanks to the adoption of carbon for the manufacture of the center tunnel, door sills, the roof arches. The latter only weigh 3 pounds. Furthermore, the fasteners of suspension, engine mounts and the rear shelf are made of aluminum.
Systematic tracking weight also affected the unsprung masses. The aluminum wheel bearings do not weigh 400 gr. The aluminum brake discs save 1 kg. As aluminum, the frame brake generates a gain of 4 pounds per caliper. Obsessive tracking weight is verified with the air in the cooling passage, which leads to 4.5 pounds of economy. The trunk trunk loses weight 6 pounds while the seats lost 12 pounds. Upon arrival, the 7 Series has melted 200 pounds. But as the same time, BMW has strengthened its technological paraphernalia, the weight loss program can be up to 130 pounds.Obviously, this gain is immediately noticeable at the wheel, especially as the 7 Series has worked to lower its center of gravity and care and suspension performance. Despite a wet track made by a passing shower, we were impressed by the passage cornering speeds of the new BMW vessel tried long-wheelbase version.
Air suspension and rear-wheel steering
In terms of dynamic behavior and sportsmanship, this model will set new benchmarks. It must be said that the series of technological paraphernalia including pneumatic suspension, automatic level control and variable damping was completed by the steered rear wheels. This system is involved primarily with the agility of the limousine, priced in tight corners a little prompt steering response. If not, well that direction gives the feeling of driving a light car. Installed for the first time, the Adaptive mode automatically folds chassis to the driver wishes. Even in Sport mode, passenger comfort is preserved. However, the six-cylinder turbo 740iL has not shocked us.
BMW still preserves until the presentation of the vehicle engine on the mystery, it appears that the box 8-speed auto focus on reducing consumption. The range include a wide choice of engines. The new 7 Series will host a rechargeable hybrid drivetrain, presumably that of the X5 eDrive at the show in Shanghai. The next 7 Series could also be the first in history to receive the label million to compete with the AMG versions of the S-Class The decision is not yet taken, but Timo Resch confirmed that prototypes peaufinaient their further point on the Nürburgring Nordschleife.
Determined to remonstrate with the S-Class, Series 7 takes a further step toward autonomous driving. Driving Assistant Systems Driving Assistant Plus, and are enriched in compliance assistant of the path with protection against side impact and rear impact against. As the S-Class, the 7 Series can automatically move in traffic. Distance cruise control and stop & go activated, the 7 Series is also able to follow the vehicle is ahead and adapt to the speed limits.The online wizard continuously manages the maintenance in the queue ensuring corrections autonomous driving. If the car deviates from the path without the driver having expressed an intention to change lanes, the steering wheel vibrates and committed a correction putting yourself in the right way. To prevent the risk of rear-end collision, the system also manages what is happening behind it. The steering effort thus hardens to prevent you from changing lanes if a vehicle behind you. But at BMW, it does not intend to substitute technology for the driver. As soon as the sensors detect the absence of hands on the wheel, the system disconnects.
Four ways to control the information display
In its desire to simplify life on board, BMW has revised the circulation in the central information display. The 7 Series now offers four ways to control the screen. In addition to the rotary knob controller and voice recognition, this limousine introduced two new functions: the touch screen and gesture design. It has not finished talking to her. We tested this innovation takes the gadget that will occupy the occupants on long journeys. Engineers have developed four gestures to control the menu display operations, decision or refusal of a phone call and adjust the sound volume. For the latter, it is sufficient that the fingers mimic, above the central console, the action on the sound volume button.This is undoubtedly more convenient, the 7 Series inaugurates world’s first parking remote controlled via the ignition key. The system does not allow parking on the cob but we managed to control the parking the car in the garage while standing outside, a few inches from her. And as Lucky Luke whistling his mare Jolly Jumper, the 7 Series came out of his garage by performing a reverse completely autonomously. By pressing a key button, it stopped just inches from us. It remained only to open the door and get on board. This system is accompanied by the detection of obstacles and if a pedestrian appears in the car field, the maneuver stops automatically. In hypernormé segment, BMW raises the debate moves into position to challenge the leadership of Mercedes. To follow in a few months during the trial of the car as standard in our databases.
