Hello, i'm the market man. I bring you the latest developments every day。
Many people have the same intuitive feeling when they go to 4s: the same budget of around 150,000, the electric cars drive a chassis, and light and looser than expensive fuel trucks. One hundred and twenty yards of high-speed vehicles are not drifting, with very small tippings on the side of the sharp turn-off, and the trans-flow belt is soft and soft, and the brakes are not clearly noding. Many of the old drivers are conscious of the fact that it's only by mastering the technology of a unique chassis that this gap can be created。
But today it is clear that the overall advantage of the bottom logic is that the overall advantage of the chassis is not based on any top-of-the-art technology, nor is it sustained by expensive air hangers, electromagnetic decomposition, and is purely the natural physical advantage of the entire structure. Fuel companies spend decades, billions of r & d, and it is difficult to level the chassis, and the original pure electric platform has been circumvented since its design. This paper provides an objective analysis of the source of the advantages of the chassis, taking into account the underlying principles of vehicle engineering and actual data, while not avoiding the inherent slabs of the chassis and providing a practical reference for ordinary people who are prepared to buy cars。
First, we understand the three hard wounds of the fuel chassis, then the power of the tram
The various types of fuel chassis are not inadequate calibrations by engineers, but the mechanical layout of engines, gear tanks and exhaust systems, which limit the ceiling of the chassis at its root and are a problem that is difficult to cure。
1. Power is always pre-positioned, the weight of the vehicle is severely imbalanced and head/foot is normal
The vast majority of domestic fuel vehicles on the market are front-loaded designs, with heavy internal combustion engines, full gear transformers and cooling systems all concentrated in the front cabin. Approximately 60 per cent of the total vehicle weight piles the front and rear weight ratios are mostly in the 62:38 sector。
This imbalance brings with it a series of short drives: a high-speed horizontal wind and a drifting tail, requiring frequent correction of the steering wheel; a clear push in the fast turn, with a large tilt in the body; and a heavy fall in the head and a rise in the tail and a marked nodding of the brakes during emergency brakes。
In order to achieve close to 50:50 gold weights, fuel trucks can only use front- and back-to-back layouts and also need to be equipped with heavy blocks of balanced weight on the back of the vehicle, not only to compress reserve storage space, but also to significantly increase research and development and manufacturing costs. Only over 300,000 high-end fuel sedans and performance vehicles will be able to use the scheme, and 100,000 fuel trucks are completely cost-neutral to achieve balanced weighting。
2. Distressed chassis, disturbed air flow and reduced high-speed stability
A large amount of installed space is required below the fuel chassis: the thrust axis, tri-dollar catalyticization, the exhaust pipe, the tank, and the full charge of the radiator pipeline are placed in the middle of the chasm, forming a high-high central cascading channel with the whole chasm of the chassis。
When vehicles are travelling at high speed, the air current impacts on the condensed discsing, creating irregular lifts, further weakening the grip of the tyres, and the higher the speed of the vehicle, the greater the sense of drift. At the same time, various types of pipelines have taken over the space placed on the hanger, and engineers have adjusted for shock loss, limited arm swings and difficult to balance the comfort of the filter with the support of the bend。
3. Vibration and noise sources make it difficult to create advanced chassis sensor
The mechanical structure of the fuel vehicle power system is complex, with pistons coming back into operation, gear gear binding, high-speed rotation of the transmission axis, resonance of the vent, and up to a dozen sources of vibration throughout the vehicle. Even if the scaffolding seismology school is in place, the constant vibrations caused by the glitch and change of the engine will pass into the cabin, undermining the overall substrate of the chassis。
Complex mechanical structures can also produce small noises, which, when passing through the pits, collide each other's racks and pipes, tend to sound loosely and even new vehicles are difficult to completely eliminate。
Ii. The core of the tram bottom reverse: four original structural dividends, purely physical advantages, not black technology
The original pure power platform is designed to be a skateboard bottom, and hundreds of kilograms of battery packs are laid down at the lowest level of the vehicle, levelling all fuel trucks from the source. These upgrades depend entirely on basic physical laws and there are no cutting-edge technologies that require exclusive patents。
1. Batteries act as giant ballast rock with a direct drop of 10 to 15 centimetres in the centre of the entire vehicle
The main household battery loads of pure electric cars are concentrated in 450 to 700 kg, the whole block is laid at the bottom of the chassis, and the whole car has a gravity height of only 380 to 430 mm; the same-grade fuel car has a common weight of 550 to 650 mm, a difference of 10 cm。
The underlying physics doctrine is straightforward: the lower the gravity, the smaller the four-wheel weight shift at the turn of the vehicle, the lower the tip of the body by more than 30 per cent. Publicly available empirical data support the fact that the 150,000-grade pure sedan moose tests generally exceed 80 km/h, and that the majority of the fuel sedans at the same price are only 70 to 75 km/h. The core source of the performance gap is low weight, which is not directly related to the level of suspension material。
Statistics on the automobile industry for 2026 show that domestic air hangers selling new energy vehicles have a capacity of less than 12 per cent, that the vast majority of flat-priced trains are equipped with ordinary steel-based tremors, and that they still have stability well above the equivalent of fuel cars, which is sufficient evidence that low weight is at the core。
While travelling at high speed, low-centre gravity has had a very strong effect, with 120 km/h cruises facing side winds, with no swings to the right or to the left, significantly reducing the sense of fatigue in long-term high-speed driving。
2. The electron is small and easy to achieve close to 50:50 equal axle velocity ratio
The tram removes large internal combustion engines and drives only one fifth of the conventional engine size, lightweight, and is able to deploy in a flexible manner at the front and back axis positions. Heavy batteries are distributed evenly in the centre of the body, and the whole weight of the vehicle is brought in to the centre of the body, so that the balance can be balanced before and after the weight is provided without additional weight。
To mention a few examples of live cars: the average measured weight of a medium pure sedan is within the range of 53:47 and the high-end pure sedan model is even a perfect match of 49. 7:50. 3. Natural solutions to fuel-heavy diseases。
The equilibrium has led to two intuitive improvements: a shift towards precision following and a synchronized response in the direction of the car, without a significant lag; and an even four-wheel grip, with a sharp acceleration of the head start and a significant weakening of the brakes。
3. Aerodynamics is fully optimized with aerodynamics, with no transfer axis, no long exhausts, complete chassis flat
The trams do not have transmission axes, long vents, complex cooling pipelines, and the bottom plate can be completely flattened, and the air flow is smoothed through with a protective floor, without creating a disorderly uplifting effect and completely improving the problem of high-speed tail drift。
The flatbeds also provide suspensed engineers with sufficient modulation space, with front- and back-to-back arm swings, shock-resilient placements no longer subject to pipe limitations, maximizing the balance between filtering and support; with a human-level advantage, with no bumps in the middle of the back row, and greater space in the back row。
In addition to this, ctb, tc battery body integration technologies, which directly use battery bags as a body receptor structure, increase the whole vehicle's resistance by more than 30 per cent. The frame is not transmutable when passing through a continuous traffic path, the chassis does not sound loose and the whole car feels more like one。
4. 80% reduction in mechanical parts and almost zero vibrations and sound sources
Fuel truck engines, gear tanks, transmission axes, exhaust system belts are subject to constant vibrating noise; electric cars retain only small electric units, electrically controlled components, and transmission-related mechanical parts are directly reduced by 80 per cent, and the entire seismic source of the vehicle is virtually lost。
The electric power plant is electromagnetic-driven, has no piston movement back and forth, has little mechanical vibration in its glitch and slow pace, and the softness and quality of the leachate is fully released and will not be masked by engine vibration. Only tyres, softness and bumps associated with shock reduction are transmitted to the cabins through speed-reducing bands and pit-baskets, and there are no types of pipes, sporadic noises from gear collisions, and a higher sense of substrate is natural。
Iii. Electric auxiliary functions are mere additions, are part of industry-wide mature technology, not exclusive black technology
Many car owners consider the smart regulation of the chassis to be self-improving black technology. In fact, rectangular distribution, kinetic energy recovery, electrical control parameter regulation are industry-wide standardized generic technologies, with no technology monopoly。
1. Millisecond-scale twist vector distribution: double-wire four-wheelers can independently control the front, front, and right and right wheel power output, automatically increasing power on the outer side of the wheel when crossing the bend and inhibiting side tilt. This electro-control logic allows all companies to purchase mature packages that are not self-researched in cutting-edge technology。
2. Motion-capable recovery support linear brakes: the electric vehicle will be able to untangle the gas-gate electric generator in reverse to drag vehicles, share the brake system load, make the brakes more smooth and do not cause fuel brake bumps, but only the basic electrical function。
3. Ota remotely updates chassis parameters: the shift to light weight, shock-mitigation soft and kinetic energy recovery power can update the program online, which appears to be intelligent and is essentially an electrically controlled software iterative. Fuel trucks are also equipped to upgrade hardware procedures, subject only to mechanical structural constraints and minimal space optimization。
A brief summary: electric controls can only optimize the driving experience, and the physical structural advantages of a battery laying remain at the heart of the huge gap in the true extraction of the oil chassis, and they do not compensate for the inherent defects in the weight and weight of the fuel truck。
Iv. Objectively looking at the two inherently short plates of the chassis of the tram, and not just at the advantage of the risk
The power of the chassis of the electric vehicle cannot be blown at all, and the structural design of the battery parlour also leads to inherent defects, which require prior knowledge of the acquisition and use of the vehicle。
1. Larger self-heaviness and faster loss of suspension and tyre
Hundreds of kilograms of batteries are directly lifting the weight of the vehicle and the reed weight is increasing significantly, with the impact springs, rubber linings and tyres bearing far more loads than the fuel vehicle of the same grade. In long-term service, the chassis of the motor vehicle is aging and wears faster than the fuel truck. Day-to-day travel avoids mass pits to the extent possible and reduces the loss of suspension shocks。
2. Low gap between chassis and higher risk of tortex contact
Battery packs are laid at the bottom of the body, and the minimum distance of the electric vehicle is generally 2-4 cm lower than that of the same fuel vehicle. Frequent use of the country's bad roads, steep slopes and high-speed belts makes the bottom of the chassis extremely vulnerable. The cost of maintenance is high once the damage to the battery pack has been hit and the price of maintenance has been raised to tens of thousands。
3. High cost of maintenance of integrated battery chassis
The vehicle model, which is designed to integrate the ctc batteries, binds the battery to the frame as a whole and, in the event of a severe bottoming, chassis deformation, which does not allow for the individual repair of the partially damaged areas, only replaces the entire chassis total, at a much higher cost than the traditional detached battery battery bike model, which is the most painful point for the current integrated vehicle type。
V. Online transmission of the two wrong car shopping areas, one-time talk, buy a car without stepping on. The pit
Wrong zone 1: the undercarriage is stable because the hanger is better than the fuel truck
Totally wrong. Tens of thousands of flat-truck hangers, materials and fuel trucks are largely the same, mostly using ordinary steel multi-company poles, twisting beam structures, and do not use large quantities of light components of high-end aluminium alloy. The core of the substrate mass is the physical advantage of low gravity, balanced weighting, not the upgrading of hardware。
Erection 2: all mixed and extended chassis have the same advantage as a pure tram
A distinction needs to be drawn between the size of an additional vehicle built from a raw pure power platform, the flattening of batteries, the preservation of gravity and the full weighting advantage; the interpolation model adapted from the fuel vehicle platform, which follows the original layout of the fuel vehicle, and batteries that can only be inserted into the trunk, the outer space on the side of the chassis, the high gravity, the imbalance in weight, the apparent difference between the chassis of the chassis and the original pure electric vehicle. Precedence is given in the selection of original pure electric platform models。
Vi. Recommendations for the exclusive and practical selection of categories of car purchasers, as required, with no blindness
1. Budget of 100,000 to 200,000, with daily urban commutes and high-speed walkovers
Precedence is given to the primary pure platform model, relying on the natural advantage of low-centre, no extra money for air suspensions, and the daily high-speed, urban road chassis quality is fully adequate; if there is a long-term concern about the cost of bottom maintenance, preference is given to the type of vehicle that batteries can be dismantled。
2. Regular trips to and from towns, bad roads and mountains okay
The electric chassis is low from the ground, preference is given to a sub-discretion with a pure suv, which is raised with a thick chassis plate and a full protection battery; fuel suvs remain more secure if they are non-painted for most of the year。
3. Planned long-term holdings for more than 10 years, with emphasis on chassis maintenance costs
Fuel trucks are less self-rehabilitated, hangers and tyres are slower, and the total replacement cost for bottom-drive maintenance over a 10-year cycle is lower; electric cars, though more stable, are more frequent in the replacement of vulnerable items and need to be weighed against their own age。
4. Pursuit of manipulation, high-speed transition experience
Air-suspended vehicles are not selected at blindly high prices, and at the same price, the primary-pump net electric vehicle type is dependent on 50:50 balanced weights, low weights, and the upper limit of manipulation is naturally higher than the fuel at the same price and is more expensive。
Vii. Comprehensive summary
Tightening the chassis is essentially an age shift in car power structures and not an exclusive black technology that can hardly be replicated. The mechanical layout of the fuel truck, which is engine-centric, has a physical ceiling that is hard to break for 100 years, while the electric cart skateboard bottom, which uses heavy batteries as natural ballasts, addresses the gravity, weighting, vibration and three chassis aching points from the root causes, is the downside advantage of the bottom structure。
We do not need to overdo mythology undercarriage technology, nor do we completely deny the mechanical experience that fuel cars have accumulated over the centuries. Disparities in the performance of the tanker-type chassis are due to different design logics at the bottom, rather than to the low r & d capacity of non-corporate firms。
When choosing a car, you should not simply be superstitious about the fact that “truck chassis must be better” in order to be able to buy a model that suits your own needs, taking into account the day-to-day road conditions, the planned age of the vehicle, and the combined budget。
Topical discussion
Did you test the fuel truck and the tram at the same time and drive it for a long time? Is that why you don't buy a train? You are welcome to leave your true view in the comment area, to praise and focus on accounts, to continuously and objectively dismantle the structure of the car, and to purchase useful dry goods for the pits。
