Ask you a question: At present, what is the minimum fuel consumption record of the domestic hybrid large five flagship SUV?
Answer: 100 km 3.9L.
And it was the Geely Star Yue L Thor Hi · who created this record. X oil-electric hybrid version.
On December 24, after the thunder god He · At the X Hybrid Technology "Live Open Season" event, Hoshikoshi L Thor Hi · X one tank of oil challenge 1300km ultra-long endurance challenge activity was officially concluded in Geely Yiwu Power Base.
This challenge activity not only successfully completed a tank of oil challenge 1300km ultra-long endurance through the whole public live broadcast, but also ran out of a tank of oil 1426.1km, the lowest fuel consumption of 100 kilometers is only 3.9L, setting a new record for the lowest fuel consumption of the domestic hybrid big five flagship SUV, fully demonstrating its excellent fuel-saving performance.
Why did it get so much? On December 22-24, Geely Automobile opened the new Thor Power DHT Smart Micron Factory to the media and users for the first time, exploring the hardening road of the world's first 3-speed hybrid electric drive - DHT Pro through cloud release.
The Thor Power DHT smart micron factory, which was opened to the public for the first time, is also an important part of the "strongest system force" of the comprehensive electrification of Science and Technology Geely 4.0 era. The new Leishen Power DHT smart micron factory, with an investment of billions of yuan, plans to produce 300,000 transmissions per year in the first phase. The level of automation exceeds 70%, which is at the first-class level in the industry.
The new Raytheon Power DHT Smart Micron Factory adopts micron-level engraving precision manufacturing and micron-level management system to fully benchmark European luxury car standards. Using the invisible "micron level" pursuit, we can achieve manufacturing that is two levels of accuracy higher than the accuracy of traditional AT transmissions. Manufacturing precision determines the quality of products, DHT smart micron factory has the industry's first-class high-precision top equipment, top manufacturing process, refining the DHT Pro hybrid electric drive 350,000 kilometers of durable quality and excellent NVH performance.
The world's leading vacuum quenching process, using the world's most advanced French ECM vacuum furnace for heat treatment, through 11 special vacuum quenching furnaces, at a high temperature of 960 ° C, fully infiltrated carbon atoms and then combined with a highly pure 20Bar high pressure helium quenching, in the case of ensuring that the surface hardness reaches 60HRC, the core hardness is controlled at 33HRC, the depth fluctuation of the hardening layer can be controlled in the range of ±0.1mm, the internal toughness and external rigidity, while the gear shape deformation is less than 8 microns, better than the industry level 2 times.
The first in Asia to realize the "intelligent heating and pressing process" for large-diameter ring gear production. EMA automatic water-cooled press hardening machine, known as "wall breaker to prevent deformation", the deformation of the planetary ring gear shape after heat treatment is controlled within ±8 microns, and the honing processing process with a small margin after heating can be applied, breaking through the current situation of non-processing after heat of the ring gear in the industry.
Asia's top rolling and honing carving process, like the "precision of the point of gold hand", through the special design of the knife fixture, to achieve from the horizontal, longitudinal, circumferential direction of the gear processing, can form a three-dimensional "on-demand distortion" of the conventional processing methods can not achieve the special tooth shape and surface irregular texture, The tooth surface roughness is increased from Ra0.4 to Ra0.25 of traditional tooth grinding, and the surface processing trace depth is less than 2 microns, which is better than the 3.2 microns of the tooth grinding process commonly used in the industry, reducing the fixed order noise generation during the meshing process and greatly improving the NVH of the meshing process. At the same time, the 1 micron journal smoothness, 0-5 micron compensation accuracy, 0.3 micron ultra-high precision coordinate measurement and other ultra-precision machining and measurement processes make the quality of DHT Pro 10,000 units consistent.
Micron-level manufacturing is not only reflected in the precision of engraving, but also in the management system. The DHT Pro is the first hybrid electric drive of the Chinese brand to integrate a 60 bar high-pressure hydraulic system, and the valve body of the hydraulic system is assembled in a "separate secret room" in a micron factory. This chamber can be cycled 25 times per hour, and the particle capture rate of 0.3 microns or greater than or equal to 0.3 microns in the air is 99.9%, which is better than the level of N95 masks, and it is a veritable IC-level dust-free assembly workshop. It is worth mentioning that the DHT micron factory also adopts the "0 error" intelligent selection system, which is finely grouped to achieve micron-level control of the entire assembly process and ensure the excellent quality of the whole life cycle.
The downline of each "artifact" must pass the strictest "graduation examination" and establish a lifelong file. Geely spent hundreds of millions of yuan to build two major test systems, EOL test and valve body test, which can carefully check all functions and NVH performance, with more than 100 steps in the detection link and up to 685 step-by-step parameters, achieving 100% automatic detection and achieving 100% qualified offline.
A good system is much more than just manufacturing. Out of sight, Geely is also pursuing excellence. As an important part of the 4.0 electrification system, Raytheon Power New Energy Test Center is the first world-class virtual simulation AI laboratory with full coverage, full simulation and full development, such as the NVH laboratory with only 8 decibels of bottom noise, which can simulate the powertrain extreme climatic environment simulation cabin within -40 °C to 60 °C, 5 meters to 5000 meters, and the high-performance laboratory that can clone the New North Circuit. It adopts the strict R&D and test standards of luxury and high-end brands to support the new energy power test of the world's top high-performance brands and supercar brands.
The strongest electrification system, the birth of the strongest hybrid artifact. Micron-level thousands of hammers and test standards derived from luxury, resulting in the world's first 3-speed hybrid electric drive DHT Pro, becoming the world's most compact, highest torque ratio, the most intelligent hybrid electric drive transmission, re-invention of hybrid. Its core technology comprehensively surpasses Japanese brands and leads Chinese brands into a new era of hybridization.
With this set of Thunder Spirits Hi · The hard power of the X hybrid system, Geely completely broke the previous monopoly of the hybrid market by the Japanese two fields. Whether it is fuel consumption, driving pleasure or driving texture, the Star-Vietnam L Hybrid Edition has delivered a satisfactory answer, coupled with its extremely powerful pre-sale price of 173,700 yuan, its future market performance is worth looking forward to.
