As the wave of vehicle electrification becomes more and more unstoppable, new energy vehicles seem to have become a choice that consumers cannot ignore when buying a car. On the one hand, whether it is a hybrid model or a pure electric model, it has shown strong advantages in terms of configuration, performance, practicality, etc., and a "green card" has conquered consumers in countless limited-license cities. On the other hand, emission standards are becoming more and more stringent, accelerating the elimination of large-displacement engines, and the internal combustion engine sentiment is becoming less and less worth mentioning.
However, although the future electrification trend has become a foregone conclusion, there are still many car companies insisting on the investment and research and development of automobile engines, and they are also large-displacement fuel engines.
Mazda: Fuel consumption comparable to 2.0T in-line 6 cylinders
Speaking of Mazda, you can probably think of it, as a recognized "paranoid" in the global automotive OEMs, it can be said that there is an ultimate pursuit of engine technology.
It has been revealed that in the latest generation of Mazda 6 models, it will be equipped with Mazda's newly developed inline 6-cylinder self-priming engine + 48V light mixing system, and will be built with RWD rear-drive platform. The car is expected to be launched in Japan in the first half of this year. It is reported that in the future, both the CX-50 and the CX-60 will use this set of power systems.
Judging from the patent diagram currently flowing out, it mainly covers the design of Mazda's new in-line 6-cylinder engine, vertical 8-speed automatic transmission and related body structures. The new in-line 6-cylinder engine, also from the SKYATCTIV-X family, will use SPCCCI spark plug-controlled compression technology to achieve efficient fuel economy.
According to Mazda data, the fuel consumption level of the current SKYACTIV-X family of 2.0L engines is even lower than that of 1.5L engines, and it is expected that the fuel consumption level of the new inline 6-cylinder engine may be comparable to that of the 2.0T engine of the same class. You know, the more cylinders, the more smooth and stable the power output is, and the 48V light mix will further enhance the driving texture, coupled with the control pleasure of the front and rear drive, which can be described as the ultimate pursuit of "man-horse integration".
Hongqi: Completely self-developed V6 and V8 have been on the road
As the first brand of luxury cars in China, FAW Hongqi took the lead in completing the replacement of 3.0T V6TD and the trial production of 4.0T V8TD. It is understood that these two engines are completely independently designed by China FAW, and apply nine advanced technologies such as micromiller circulation combustion system and "HOT-V" dual-center turbocharging. Both engines will serve as flagship power for Hongqi's high-end luxury model.
Among them, the V6TD replacement engine has a maximum net power of 340kW and a maximum torque of 600N·m, which is 41.6% higher than that of the previous generation, and the economic index is 6.6%.
The 4.0T V8TD engine has stronger performance parameters, the maximum net power reaches 485kW, the maximum torque is 850N·m, and the book data directly crushes Audi's 4.0T and BMW's 4.4T engine, although the actual still depends on the final loading data, but it is enough to show that our domestic large-displacement engine has also reached the international leading level of similar models.
The V8TD has taken the lead in being installed on Hongqi's first supercar, the Hongqi S9, and is accompanied by three power motors, and the maximum power of the system has reached 1400 horsepower. Acceleration from 100 km/h takes only 2 seconds and the top speed can reach 400 km/h. The car is currently on pre-sale and is limited to 99 units worldwide.
The limited number of 99 Units of The Hongqi S9 may be a little far away from us, but it is reported that the large-scale SUV Hongqi LS7 that will be released this year will also be expected to take the lead in carrying the V8TD, which will be one step closer to the dream of V8.
Great Wall: V6+9AT exclusive hardcore off-road?
In the past two years, Great Wall Motors, which has grabbed the limelight in hardcore models, has also invested in research and development in the core power field. In August last year, the Tank 500 debuted at the Chengdu Auto Show, and the pre-sale opened two hours with orders exceeding 20,000 and the weekly order exceeding 40,000.
However, compared with this car, The Wheel Brother is more concerned about the big "heart" of the V-shaped 6-cylinder inside, a completely self-developed 3.0T V6 twin-turbo engine code-named 6Z30. Using miller circulation, GDI+PFI dual injection system, 350Bar high-pressure injection, dual VGT supercharger, dual electronic throttle valves, integrated water cooling and intercooling and other advanced technologies, thermal efficiency reached 38.5%.
The 6Z30 engine equipped with the tank 500 has a maximum power of 260 kW and a maximum torque of 500 N·m, which is completely inferior to the BMW X5 and Audi Q7. In addition, the engine's low torque performance is outstanding, at a low speed of 1000 r/min can burst 340N·m of strong torque, so it is also quite suitable for the positioning of the tank 500 hardcore off-road, and can be calmly coped with in the face of extreme off-road scenes such as climbing.
It is worth mentioning that the tank 500 is also matched with the latest 9AT gearbox of the Great Wall, which is also the first mass-produced longitudinal 9AT in China, with a 48V light mixing system, which can bring a strong and smooth driving texture.
Write at the end
In recent years, it is regrettable that one after another large-displacement classic cars have come to an end, but fortunately, there are still paranoids in the market who are sticking to their dreams. On the other hand, while large-displacement imported cars are gradually withdrawing from the market, in fact, it has also left a blank for Chinese car companies, and the showdown of domestic large-displacement engines has just begun.
