Three Millimeters!

In fact, many high-end models have chassis height adjustment function, which is adjusted through an independent air suspension system.

However, their lifting range is very limited, mostly between 5 and 15 centimeters, and their effect is not very obvious. Therefore, in actual use, they are not very practical and are more of a gimmick.

However, the lifting device designed by Chen Mo is different. The suspension system of this bulletproof off-road vehicle originally adopted a multi-link independent suspension, which has a great degree of design freedom.

By designing the constraint angle of the connecting motion points, the suspension can actively adjust the wheel alignment during compression, allowing for complete matching and tuning to the vehicle model, maximizing tire grip and thus improving the overall vehicle's handling limits.

Furthermore, it can effectively control the camber angle of the wheels while driving, resulting in excellent performance in both comfort and handling. It also has a lot of room for adjustment and modification possibilities.

This greatly facilitated Chen Mo's improvements. Combining the Batmobile's suspension and transformation systems, Chen Mo improved the multi-link independent suspension system, enhancing the wheel adjustment range while ensuring sufficient strength and stability. He directly merged the independent chassis lifting system and independent suspension system of other models into one.

Through clever design, this upgraded independent suspension system is not particularly complex in structure. While possessing strong shock absorption and wheel adjustment and chassis lifting functions, its simple structure also makes the system very strong, stable and reliable.

The height adjustment range of the four tires is much larger than that of other high-end models with height adjustment functions, and the effect it can play will be unmatched by these models.

By adjusting the wheel position, the chassis height can be lowered to a minimum of 10 centimeters to ensure maximum stability and achieve higher speeds, and can be raised to a maximum of 50 centimeters, which is higher than the chassis height of ordinary military off-road vehicles and armored vehicles. Only a few specially modified extreme off-road vehicles can rival it. Its off-road performance is extremely strong, and it can easily cross various complex terrains and obstacles, making it incredibly capable.

Aside from the significant changes to the suspension system, other systems have also undergone some modifications, but the extent of these changes is not substantial. Moreover, Chen Mo has already completed the modifications to the main parts, and the various teams in the R&D and design departments only need to make minor adjustments based on Chen Mo's modifications and refine some parts. The overall changes are not significant, the workload is not large, and it will not take too long.

Chen Mo asked them to finish within three days, which seemed like a very tight schedule, but Chen Mo knew in his heart that the difficulty was not actually that great, it would just be very busy.

Chen Mo sent the preliminary revised design drawings to the R&D and design department. They quickly made corresponding adjustments to the relevant details according to Chen Mo's modifications, such as the size of the parts and the specifications of the components.

The specific modifications to the suspension system, components, and other parts were completed by the respective teams in the R&D department, while the design department, which was mainly responsible for the body shape, interior and exterior trim, also received a set of modified drawings from Chen Mo.

In fact, a car can be simply divided into two parts: the body and the chassis.

The most crucial core part of the entire car, all the major functional systems, are located on the chassis, including the engine, clutch, steering wheel, fuel tank, and other transmission, driving, steering, braking, and electrical control systems.

Even without a body, the assembled chassis can already drive normally. In the testing phase of automobile production, it is common to see car chassis without body shells driving around the test track like convertibles under the control of test personnel.

If the chassis is the body of a car, the core of its operation, then the body shell is like its clothes and armor, serving both aesthetic and protective functions.

While it's possible to travel naked, it's certainly not as comfortable or safe as wearing clothes and armor.

The body of an armored car is like heavy armor, providing stronger protection for the car's engine and other systems, as well as the occupants.

However, the blueprints that Chen Mo sent to the design department stripped away this crucial layer of heavy armor!

On the blueprints, Chen Mo did not change the original body frame, but he removed all the body armor, ceramics, special alloys and bulletproof composite materials that served as bulletproofs, leaving only the bulletproof glass, and replaced the entire body shell with 3 mm thick steel plates.

Although it is much thicker than the 0.8 to 1.2 millimeters of ordinary vehicles, it is still far inferior to the original Bulletproof Armor, not to mention the bulletproof materials such as built-in ceramics and special alloys.

Expecting a three-millimeter-thick steel plate to provide strong bulletproof protection is simply impossible. At most, it's only slightly sturdier than an ordinary off-road vehicle and can withstand shots from small-caliber handguns. It absolutely cannot withstand shots from large-caliber handguns and rifles, let alone attacks from grenades and bombs. With such defensive capabilities, it cannot be considered a bulletproof vehicle at all.

Could it be that their new boss is planning to change their previous focus and abandon the armored vehicle business?

It's not impossible. After the boss's improved version of the new engine was manufactured and installed on the prototype, many of them went to the test track to watch the test and had a vivid memory of its powerful performance. If, as shown in this new design, the heavy Bulletproof Armor is removed and replaced with this three-millimeter-thick ordinary shell, then the weight of the vehicle will be reduced significantly, and the performance of this off-road vehicle will be even more powerful. It's not impossible that its acceleration will surpass that of a sports car.

With its formidable off-road capabilities, superior acceleration, and top speed, it might be even more popular than armored vehicles.

However, if that's really the owner's plan, why keep the 3mm thick steel body panels? Wouldn't it be better to just use regular 1mm or even 0.8mm thick steel panels? These extra two times the weight would be three or four hundred kilograms, which would have a significant impact if speed is the priority.

Such a single layer of steel plate can only withstand small-caliber pistols. Even if you want to continue to promote the idea of bulletproofing, it is not very effective. It is impossible to achieve all three. It would be better to simply abandon the concept of bulletproofing and focus on off-road capability and speed.

Although they didn't understand, they quickly made the modifications according to Chen Mo's drawings and requirements. In comparison, their work was actually easier.

Chen Mo was very satisfied with their design of the vehicle's exterior and did not make any major modifications. Therefore, they only needed to remove the Bulletproof Armor structure and modify some parameters of the vehicle body. Referring to ordinary non-bulletproof vehicles, the modification was very fast, and it was completed on time within three days.

Three days later, the modification work on the entire model was completed, and the production line was integrated and adjusted, ready to be put into production at any time.

The original modification workshop has been equipped with new smelting, forging, casting and processing equipment, and it will serve as an engine production center responsible for the production of new engines.

However, engine production is not the only work in this workshop, as can be seen from the layout of the workshop.

At the far end of the massive factory building is a row of several huge vacuum arc melting furnaces. These devices, which can melt a variety of high-melting-point metals under vacuum conditions, are typically used in the production of special alloys.

The engine block and pistons are made of high-strength aluminum alloy, while the crankshaft is made of alloy steel. Taylor Motors had never mass-produced engines before. The aluminum alloy and alloy steel used by the engine R&D team were all finished alloy materials purchased from outside and then remelted and processed. Therefore, they did not actually have a formula for high-strength aluminum alloy and alloy steel materials for engines.

However, this was no challenge for Chen Mo. The technological reserves he brought from HYDRA were quite comprehensive. The formulas for a few engine alloys were nothing to mention. Among the neatly arranged row of vacuum arc melting furnaces, two were specifically used to produce engine aluminum alloys and crankshaft alloy steels.

Various raw materials are added to the furnace in a certain proportion for smelting. Under vacuum conditions, these metal raw materials are rapidly melted by the high-temperature electric arc of thousands of degrees formed by the discharge between electrodes. Various metal elements are fused together and become one.

After being fully melted and combined, the liquid alloy is then injected into a pressed mold. After gradually cooling, the pre-cast cylinder block and crankshaft will enter the next process, where they will be roughed and finished by CNC machine tools.

This engine production line, composed of numerous pieces of equipment, from the initial alloy smelting, casting, and processing to the final assembly, occupies only half of the space in this huge factory. On the other side, a production line that also starts with two vacuum arc melting furnaces but includes more large machinery produces steel plates of various shapes and sizes.

This is the production line for the car body shell. The molten gold-red metal liquid is pressed into a three-millimeter-thick homogeneous steel plate by a rolling mill after several processes. Then, after cutting, stamping, welding, and assembly, it becomes a series of sturdy, smoothly curved silver car body shells. The frame, roof, doors, engine hood, trunk lid and other parts are all made of this steel plate.

However, this steel plate is not an ordinary product. Otherwise, Chen Mo could have used ready-made steel plates purchased directly, just like other car companies, without having to start from scratch to smelt and produce steel plates himself.

Just as the design department had guessed, after improving the engine, Chen Mo saw the car's potential in speed and decided to push the speed and acceleration performance to the extreme.

However, he does not intend to abandon bulletproof features in favor of off-road capability and speed. Instead, he plans to balance off-road capability, speed, and bulletproof capability to fully unleash the vehicle's potential and maximize its competitiveness.

Off-road capability is no problem at all, but to improve speed and acceleration performance, the vehicle weight must be reduced. Reducing the weight of the vehicle while ensuring bulletproof performance seems impossible to anyone, but it is a very simple thing for Chen Mo.

Not to mention Dr. MacLane's invention of the Alpha Alloy, which boasts superior performance second only to Adamantium and can be manufactured using conventional materials without the need for Vibranium, Chen Mo also had a variety of high-strength special alloy formulas in the technological data he brought from HYDRA.

After comparing several of the world's most powerful alloys, Chen Mo selected the one currently in production from a large database of special alloys.

Compared to those expensive Super Alloy such as Titanium Alloy, this special alloy, HYDRA H-2, is not only more defensive and lighter, but also far less expensive. Although it contains many expensive Super Alloy, the amounts are small, and the average cost is not high.

This 3mm thick special alloy steel plate is not much heavier than the shell of an ordinary car. The overall weight of the car is less than 100 kilograms heavier than if ordinary steel plates were used, which is equivalent to carrying one or two more people. It does not have a significant impact on the car's acceleration performance or top speed.

In terms of defense, it is comparable to, or even exceeds, the original vehicle armor weighing over a ton.

Don't be fooled by the fact that this special alloy steel plate is only three millimeters thick; it is extremely strong. Ordinary handgun bullets cannot even leave a deep mark on it, and bullets from regular automatic rifles can only cause slight dents in the steel plate, but cannot penetrate it at all. Even under continuous high-intensity attacks, it can maintain a strong and durable defense.

Unlike ordinary armored vehicles, if the same area is attacked multiple times in succession, the Bulletproof Armor or ceramic plates will shatter and the vehicle will be unable to guarantee its defensive capabilities. It will be easy for subsequent attacks to break through the defenses and cause harm to the people inside the vehicle.

Therefore, although the power of the strongest attacks they can withstand is not much different in terms of data, in actual use, the actual performance and durability of the H-2 special alloy steel plate far exceed the bulky multi-layered Bulletproof Armor of ordinary bulletproof vehicles.

This is of great significance to the safety of the occupants inside the vehicle.

The purpose of armored vehicles is to withstand attacks for a certain period of time in the event of an emergency, ensuring the safety of the people inside and allowing for a rapid evacuation from the danger zone.

The time between the attack and the successful evacuation determines the life or death of the people inside the vehicle!

If the attackers have heavy firepower, such as machine guns or other high-rate-of-fire, high-powered weapons, even if the armor of an ordinary bulletproof car withstands the initial attack, it is very likely to be breached under subsequent continuous attacks, leaving very little time for evacuation and escape.

With this H-2 special alloy steel plate, even under continuous fire from multiple automatic rifles or machine guns, Chen Mo's bulletproof off-road vehicle can still withstand a long time, providing more time and protection for safe evacuation.
