　　As a Mercedes-Benz medium and large RV, this E-Class, which was officially released in 1984, has always been the leader of new technologies in the industry. In fact, its E is the first letter of German Einspritzung (fuel injection technology), because it is the first production car adopting this technology. At the test drive site, the organizer showed us the historical stories of Mercedes-Benz E-Class passed down from generation to generation. Behind every classic gene inheritance are the painstaking efforts of the royal designers.

　　There are two outstanding features of the latest generation: one is the addition of an electronic warning system for driving fatigue, and the other is that the length of the car is 12mm longer than that of the previous generation and the wheelbase is 20mm longer. Of course, the brand-new configuration of the engine and the application of the 7-speed gearbox make this car not only a car for passengers, but also a car for drivers.

　　Appearance: fashion elements are embedded in the classic car body.

　　This model, which was first launched at the Shanghai Auto Show in China, was once rumored to have absorbed some design elements of other luxury cars, but when it was seen, these claims naturally fell apart. When the reporter asked Mr Haller, the designer of the car who ate at the same table, whether he would consider drawing lessons from other people’s excellent factors when designing the car, Mr Haller simply said "Never". He went on to explain that it has always been to lead rather than learn from others. Based on this, the new E-Class combines the classic elements of E-class, the characteristics of M.Benz’s new generation family and the outline of lines. At first glance, it is not only atmospheric, but also very sporty. From the four-eye diamond headlights, V-shaped headstock and deep high waistline transplanted from Fascination concept car to the arrangement of wedge-shaped body and horizontal taillights, it has fully demonstrated the streamlined and avant-garde high-performance style, so the drag coefficient is as low as 0.25 except for the lean figure with C-Class, and therefore this generation of cars has returned to the design of W124 with double doors, convertible and other derivative cars.

　　Interior: concise and practical

　　Compared with some fancy interiors, the interior design of the new E300 is simple and practical. Sitting in the car, you will find that the Command control key greatly simplifies the cumbersome design of the center console in the past. Smooth and sharp lines are everywhere, the sub-gray color scheme is harmonious and eye-catching, and the circular sports/comfort mode button on the armrest is very easy to use. In addition, all the cars currently on sale are equipped with navigation display screens at the top of the center console. Both the control keys and the image display are clear and logical, so although there are many buttons, they are not messy. Massage seats that can be heated or cooled are very comfortable, which is our favorite configuration when conducting long-distance tests. Of course, even ordinary cars are enough to ensure that you can travel comfortably.

　　Space: spacious and comfortable

　　In terms of internal space, the further increased body size provides a more comfortable driving environment for passengers, and with two-stage panoramic sunroof, the internal space is more spacious and bright. The newly equipped ambient lighting system has a five-level brightness level, which can not only provide lighting for the whole car, but also create a relaxed and quiet sense of luxury during travel. Elaborate interior colors and materials not only arouse the psychological resonance of drivers and passengers, but also have unparalleled practicability. In addition, the newly developed reversing video system and rear entertainment system (E300 fashionable standard equipment) not only enable drivers to park easily, but also enable rear passengers to enjoy a more pleasant ride experience during long-distance travel.

　　Power control: excellent work

　　The E300 is equipped with a 3.0-liter V6, the output power can reach 170 kW /230 HP, and the maximum torque is 300 Nm. With Mercedes-advanced 7G-TRONIC seven-speed automatic transmission, the whole shift process is smoother and there is no hysteresis, which makes the E300 have excellent handling performance.

　　During the test run, some young people always compare E300 with it intentionally or unintentionally after occasionally trying some sports cars with a capacity of more than 4.5L or coupes with larger displacement. The conclusion of the comparison must be that almost all cars on the market are under-powered. This is the result of inexperience and blind comparison, and of course, it is also in their conclusion. In fact, the E300 is equipped with a new customized displacement and output power after abandoning the previous generation of supercharge, so the power output is linear in stages, which is imperceptible without careful understanding. The result of the actual operation is that in the starting and accelerating stages, even if the tachometer pointer does not rise rapidly, the car has started easily and shot out immediately. After 2500 revolutions, the power of the car began to approach the peak slowly. At this time, the power is continuous. Whether it is accelerating overtaking or slowly fueling, the car is running in an orderly way. In addition, when driving at a constant speed, the noise of the car is very low, and the sound insulation effect is better than that of the previous generation. However, if the oil supply is too large, it will produce annoying and monotonous noise, and the tail throat sound is not very good. The response rate of both the automatic seven-gear gearbox and the shift paddle is ok, and the gear ratio design of the second and third gears is also very ideal. Because the body is heavy and the chassis is extremely solid, even if the speed is 160 kilometers, the car still runs steadily, and its control can be seen.

　　If we really want to find the shortage, it is that when the speed is 80-90 kilometers per hour, the power output is steady but not fast enough when accelerating rapidly, that is, the power comes slowly when accelerating rapidly.

　　Safety: active and passive care.

　　The whole car follows the car’s consistent safety standards and introduces the newly developed driver’s attention warning system, which monitors the driver’s attention level in real time through more than 70 parameters to remind sleepy drivers in time to avoid danger. In addition, the whole car also comes standard with the PRE-SAFE system, intelligent lighting system and 9 airbags (including the newly added driver’s knee airbag). All protection systems work in perfect coordination, which promotes vehicle safety to a new height.

　　More high-strength steel is used in the body structure of the new car, but the kerb quality has not been significantly increased, because the weight and structure have been optimized more scientifically. In addition, in order to ensure that the car has better pedestrian collision performance, its hood can bounce up after being hit hard, so as to better protect the head of the hit pedestrian.

Introduction to combat

The Battle of Axle was an offensive campaign against the Japanese Puppet Army in the southeast Axle area of Huai ‘an County, Jiangsu Province, during the period of War of Resistance against Japan. The campaign began on March 5, 1944 and ended on March 6, 1944. After three stages, namely, the attack on the bridge, the aid from Lujiatan and the strategic shift, a total of 465 Japanese captains (including 24 prisoners) and 483 puppet troops (including 168 prisoners) were wiped out, and 53 bunkers were destroyed, which "created a new record of Japanese invaders captured alive in Central China". The victory of this campaign has disrupted the plan of "expanding the countryside" and "strengthening the reclamation" of the Japanese and puppet troops, made the central Jiangsu region a relatively stable rear base, and created good conditions for our troops to train and prepare for the strategic counterattack. The victory of this campaign also opened up the strategic links between the Soviet Union and the northern Jiangsu, Huainan and Huaibei regions, realized the fundamental improvement of the Sino-Japanese war situation, and became a symbol of the strategic counterattack in the battlefield behind the enemy lines in the Soviet Union.

Talk about criticism

In the Battle of Axle and Bridge, the New Fourth Army concentrated more than five regiments, combined guerrilla warfare with mobile warfare, and carried out siege and aid operations against important fortified positions of the Japanese army, creating an example of annihilation war in Central China of the New Fourth Army. Learn from the past and know the present. It is of great practical significance to comprehensively and objectively analyze the winning mechanism of the vehicle-bridge campaign and fully absorb its essence nutrients, so as to improve the efficiency of studying war cases, truly learn from history and strengthen the preparation for military struggle.

Campaign planning should focus on the overall situation and grasp the joints. The great victory of the vehicle-bridge campaign was first benefited from the overall situation and grasping the joints when planning the campaign. The 1st Division and the Suzhong Military Region accurately located the attack direction in the eastern part of Huaibao, which was based on the actual situation in Central China and the overall consideration made according to the overall strategic situation in Central China. First, the area is located at the junction of the two Japanese divisions. If it is attacked, the main force of the Japanese 65th Division, which is in charge of the defense in this area, is far away from Xuzhou, so it is difficult to reinforce in time. The possibility of the neighboring 64th Division’s aid is extremely low, which is convenient for a quick decision. Second, the 7 th Brigade of the 3 rd Division of the New Fourth Army is located in the east of the Huaihe River, ensuring the safety behind the north side of the 1 ST Division. In fact, in the Battle of Axle, the 7th Brigade captured the Zhuweizi stronghold between Lianshui and Axle, and effectively cooperated with the Battle of Axle. Third, this area is the connecting part of Jiangsu, North Jiangsu, Huainan and Huaibei. Controlling this area is conducive to communicating the strategic links between the four areas and implementing strategic maneuvers.

In order to open up the situation in the eastern part of Huaibao, we must capture the axle. Capturing Jingkou or Axle is the key point for the leaders of the 1st Division to consider. Finally, the determination to capture the vehicle bridge is mainly due to the following reasons: First, the vehicle bridge is the enemy command center in this area, and if the vehicle bridge is captured, the enemies of Jingkou and Caodian will be isolated and may withdraw without fighting, so that the campaign will get the best effect; Second, the axle is located in the center of the enemy, and the offensive action is easy to surprise the enemy and win by surprise; Third, the terrain around the axle is more conducive to the rapid approach of attack force than Jingkou; Fourth, the main reinforcement direction of the Japanese and puppet troops may come from Huai ‘an, and there is a good natural ambush position in Lujiatan, northwest of the axle, which is conducive to annihilating the enemies who come to aid. Facts have proved that only by grasping the joint point of the axle can we quickly achieve the operational goal, and then revitalize the overall situation of the Soviet Union’s war of resistance against Japan. It can be seen that in the future campaign planning, we should focus on the overall situation of the campaign, plan the campaign action from a strategic height, grasp the winning joint, and promote the overall planning with local accurate planning, so as to have a clear goal and get twice the result with half the effort, thus creating favorable conditions for winning the campaign.

Campaign operations should pay attention to careful preparation and flexible tactics. The victory of the Battle of Axle also stems from careful pre-war preparation and flexible tactical command. In order to carry out the vehicle-bridge battle, the New Fourth Army made careful preparations. The first is to conduct in-situ reconnaissance in detail. As early as 1943, Su Yu and others kept walking around the areas near the strongholds such as Cheqiao and Caodian, and made a field investigation on the terrain and enemy situation along the way. Before the war, detailed on-the-spot reconnaissance was made repeatedly on the ambush positions around the axle and Lujiatan. The second is to reorganize the battle sequence, appropriately adjust the organization and cadres, unify the command organization, and clarify the division of tasks. Third, the operational plan was carefully formulated, the possible complicated situations were carefully analyzed, various plans were studied, and the time, place, driving route and attack time of troops concentration were accurately calculated and required. All ministries conducted pre-war rehearsals according to their tasks and field conditions. Fourth, the unified deployment of ammunition and equipment, the organization of intelligence stations, field hospitals, transport stations, a number of special equipment and communication tools, the collection of a large number of boatmen and ships, and the strengthening of logistics support. Fifth, fully mobilized before the war, promulgated the regulations on rewards and punishments during the war, organized commando teams and commando groups, and carried out combat competitions.

In terms of tactical application, the vehicle-bridge campaign has played a combination boxing of attacking and aiding simultaneously, which has become a model of the close combination of guerrilla warfare and mobile warfare. Before the war, the New Fourth Army carried out long-distance and over-the-point raids with absolute superiority, supplemented by sabotage, which took the enemy by surprise and hit the enemy’s key points. In the battle, the New Fourth Army mainly attacked and blocked the enemy, supplemented by sneak attack. On the front, the scattered combat teams flexibly used the tactics of encircling circuitous and divide-and-conquer to conquer the enemy bunkers one by one. At the same time, accurately judge the direction of the enemy’s reinforcements, build sniper positions, preset mines, and deploy powerful mobile forces on the side of the enemy’s main roads to form a number of commandos. By adopting the method of "letting go of the vanguard, attacking the middle and attacking continuously", the enemy’s reinforcements were annihilated in batches, which not only mobilized the enemy’s reinforcements to attack, but also ensured victory in attacking. The two closely cooperated and echoed each other, and finally won the battle. In future operations, campaign actions will be more complex and changeable. When preparing for the campaign, we should always be vigilant and make overall consideration, so as to make early preparations, be thorough and meticulous, and give consideration to interests. Tactically, it is necessary to emphasize flexibility and initiative, to adapt to changes and seek innovation through changes, so as to win by surprise and defeat the enemy invisibly.

Campaign support should focus on relying on local governments and complementing the military and local governments. The victory of the vehicle-bridge campaign is inseparable from excellent campaign support. Before the war, the people of Huaibao wholeheartedly supported and supported the attack on the vehicle axle. Various districts and townships set up front-line organizations and held repeated meetings to discuss and implement various specific front-line tasks to ensure that "everything is subordinate to the front line and everything is for front-line victory"; In-depth mobilization was carried out, and the resounding slogan "We will give whatever the New Fourth Army wants" was put forward, actively supporting the army and supporting the front. First, actively supply daily necessities such as grain, oil and salt, tea, etc., and only an feng in Baoying County raised nearly 50,000 kilograms of grain; The second is to assist the troops in making ladders and other critical equipment; The third is to organize a stretcher team, raise more than 100 pairs of stretchers, and organize vehicles and ships to transport military supplies such as troops, migrant workers and guns and ammunition; Fourth, through various means such as standing guard, reconnaissance, sending letters, transporting the wounded, and directly participating in the war, we will assist the main forces in fighting. It was the enthusiastic support of Huaibao people that provided sufficient manpower and materials for the New Fourth Army, gave full play to the great advantages of the people’s war, and laid a solid material foundation for the victory of the Axle Campaign. In future operations, in order to effectively fulfill our military’s historical mission and strengthen our ability to win battles, we must persist in hiding our war capabilities among the state and the people, make overall use of various social resources, and give full play to the supporting role of social manpower, material resources, financial resources, especially scientific and technological strength in army building.
