Performance and driving: a high performance car logo, in addition to energy saving technology Competition, the provision of personalized modes of driving has become a trend
While the new 7 Series will be a nominal entry section for 740Li, but in fact there is no BMW 4.0 L engine for its equipment. Numbered N54B30 3.0
L inline 6-cylinder bi-turbo engine as the 740Li's "heart" of it and X6
xDrive35 and the 335i equipped with the same engine model series, but the maximum power of 240 kW has improved over the previous two, in addition, in 1500 ~ 4500
r / min speed range, the engine is to 450 N • m maximum torque of full output, such a high efficiency power output is fully beyond the former 740Li's 4.0 L
V8 engine. The new 740Li's 0 ~ 100 km / h speed score of 6.0 s, only three cars in the most rapid one, but significantly more than the previous generation 740Li
6.9 s results.
Three cars in the 740Li minimum displacement, but driving is the most surprising performance. If the inherent mindset of view, mere 3.0
L turbocharged engine displacement, it wanted to curb mass up to 1970
kg of the big man has good acceleration and power of the adjustment is certainly no matter regardless, it is difficult to control. In fact, if not stated beforehand that the driver probably all likelihood aware of any 740Li is powered turbo engine. This straight 6 engine power output is extremely linear, or even people simply do not feel when the turbocharger is actually involved. Drive unit is still the leading 6-speed Steptronic automatic transmission, in addition to fast response fluid, the most impressive is that when the pedal to the metal, the transmission will drop rapidly with 4 block, so that drivers speed fun.
From the previous generation, the driving dynamics control system already is the standard 7 Series, the new 7 Series is the addition of a "campaign
+ "Model, thus driving style into four types. Press the shift button next to the handle can be converted" comfortable "," normal "," movement "and" Movement
+ "Four different driving style, not only can change the dynamic damping system settings and dynamic stability of system response, you can also change the automatic transmission's shift timing and throttle control and steering assist system layout.
Simply not sufficient to show that science and technology to increase power, the new 7 Series also seek to reduce fuel consumption, BMW offers a set of energy for this program, called "EfficientDynamics" (high power). Which is the most innovative brake energy recovery system, which can make the new 7 series hybrid, like those who, like, the braking energy into electricity to charge the battery, thereby reducing the engine load, reducing fuel consumption. But with the hybrid model, the new 7 Series is still a lack of automatic start-stop system, because BMW's automatic start and stop function only supports the manual transmission.
Compared with the 740Li, S350 true displacement, 3.5 L engine is the second generation of Mercedes-Benz V6 engine, the previous generation V6 engine into a row of two 3-valve structure, valve replacement was 4, the maximum power of 200
kW, maximum torque 350 N • m. Although at this stage of the S-class is also to young sports development, but what before the Mercedes-Benz BMW driving seat to say what is not empty talk, dynamic performance from a practical perspective, S350's acceleration obviously can not go and 740Li Shidalichen of Effort to contend, but also showed very different dynamics driving Mercedes-Benz concept.
Although the S350 7.3 s of 0 ~ 100
km / h acceleration time, as the 740Li will not be back as possible so that owners mad, but it is also a great achievement, and both high speed cruise or mountain in the gallop, S350 car has remained an elegant atmosphere, completely outside the car out all kinds of noise isolation, with excellent quietness. 7 block of Tronic transmission not only with the V6 engine with great understanding, but also the cooperation with the suspension system provides three different modes of driving. Shift manual mode which is not using picks, but the use of steering wheel shift buttons next to. Driving S350, we prefer comfort mode, then you will find always early Shengdang transmission and air suspension will also set their own style, comfort, will come from road impact, vibration and noise being completely absorbed, the post- row passengers feel very comfortable ride. Campaign mode, in order to offset body roll when cornering, suspension is set still more tough, and time will be at a higher speed Shengdang there. Compared with the side of the two rivals, S350 of the accelerator can not be considered light, and even some heavy, more than 5
m in length and long wheelbase also limit the extent of its fierce drive, but the modest performance of heavy driving comfort and care about nature driving mode, are illustrated S350 is a model to meet the rear seat passengers. Air Suspension System (AIRMATIC) is the S-class technology in a number of topics not be avoided, except in the comfort and sport modes to play a role, it can also be due to the speed and power output and their own height and damper adjustment of the soft body hard-set, so that more precise manipulation S350.
After the drive is not an expert Audi, A8L 2.8
L and 3.2 L models are based on the precursor layout, use them to and 740Li, S350 contest is not appropriate, but do not forget there are big-name Audi quattro all-wheel-drive, select the 4.2 FSI quattro technical performance came against is more appropriate, but the engine leapfrog into a V8. V8 engine with FSI technology, Audi is also brought together all the new technology a driving force, with the advantage of 4.2 L of displacement, 257 kW maximum power is the most powerful of three models, 440
N • m of torque just crazy 740Li less than 10 N • m. Perhaps the third-generation A8's dual-clutch transmission will be technology-led S-Tronic transmission, but that does not mean that the current 6-speed tiptronic transmission, this is not good, in addition to the smooth and efficient transmission, the transmission mode is also provided by S obvious effect, shifting time delay brought more direct power, can easily become active to A8L abnormal activation of the steering wheel at any time the gear change paddles, but also make the drivers are freely control the power.
ASF all-aluminum body is the Audi A8L's signature technology, to reduce the burden of quality, compared with two competitors, the effect is also quite significant. Although three high car, A8L
4.2 is the only four-wheel drive with V8 power and equipment, system models, but 1850 kg of the curb mass but is the smallest of the three, the largest BMW 740Li than the quality of a full less 120 kg, but the 0 ~ 100 km / h The speed score of 6.3 s, or lost 740Li
0.3 s.
A8L's driving style is the most portable of the three, whether the foot of the throttle, or the intensity of the steering wheel, better than Mercedes-Benz, BMW and lighter, people are driving is an easy to enjoy. In fact not only the A8L, at all levels, the Audi have persisted in such a pleasing driving experience. 7 series and S-class can provide different styles of driving mode, A8L is no exception, control panel, press the "Car" button on the LCD screen will jump out of suspension system configuration option, to select "elevated" "comfortable" and "Automatic" and "exercise" 4. In the normal state Keyi speed, steering wheel rotation angle, G value, the level of the body and many other information to calculate the angle, the initiative to adjust shock absorber damping, air spring stiffness and ride height, of course, drivers are self-adjusted according to personal preference Select automatic mode than comfort or sport settings. Body may be lighter, due to light or driving feel, A8L control them is extremely flexible, quattro all-wheel-drive also play a crucial role in the central Torsen differential is a core A8L-wheel-drive system, As a result of mechanical structure, its response speed is more agile, but also rely on the stability of the electronic braking systems were compared, quattro system is clearly more fun to drive.
Configuration and technical equipment: Do you have I have, high car configuration is inevitable convergence of
All three models are configured with a dazzling, but it is not our current focus, if carefully studied the configuration of the list of luxury cars, you will find more high-end luxury cars more difficult to configure the difference, Which trendy equipment, even omission, would immediately change in the next paragraph or updating the medium-term in conjunction with padded. For most people, talking about the price of luxury cars is a very exciting thing, 740
Li according to configuration, a total of three, this one is ranked in the middle reaches of luxury, but the configuration is also very thoughtful, and the price of 1.355 million yuan in three of the most competitive. S350 also offers three models, dynamic model to install some of the AMG appearance package, although not related to performance, but the price has soared, 1.448 million yuan of price and S350
4MATIC matched. A8L 4.2 FSI
quattro participate in this contest it is patronizing, not only emissions, "excessive", 168 million worth also "excessive."
Overall, Germany has become the third-strong development trend of high-end luxury car makers, despite the Japanese luxury brand in recent years made great progress, but the real essence of competition to produce is still the German Department of the three companies, and 7 series, A8 and S-class difference between the three and a half generations of the situation in turn is also very dramatic, no one can stop, breathing will definitely be more intense competition, of course, the ultimate benefit of consumers.
