Have you experienced a car driving more than 100 kilometers after the fuel gauge pointer remains motionless, and the watch endurance only drops 1 kilometer?
If I hadn't seen it with my own eyes, I would never have believed that this would happen on a hybrid car. In the Yunnan-Guizhou Plateau with an average altitude of 3500 meters, with a full load of four people, a hybrid SUV can actually open more than 100 kilometers of fuel gauge hands without moving, and the endurance of the meter is basically unchanged, which is a difficult thing to imagine before.
I know that seeing this, a lot of people will say that there is nothing strange about this. The oil car runs at high speed with the average fuel consumption to reduce the meter endurance will be more and more, and the tram will use the kinetic energy recovery on the plateau to achieve the endurance more and more, not to mention the hybrid.
Indeed, the endurance of the table will change according to the actual fuel consumption. However, the emphasis here is not that the endurance is running more and more, but in the process of driving more than 100 kilometers, the cruising range of the table is basically unchanged. Isn't that a bit incredible for a hybrid SUV with only a 1.8kWh battery? So, even if I saw it with my own eyes, my first reaction was more inclined to "broken" the fuel gauge, or the word game that manufacturers played here in the mileage.
So, after arriving at my destination, I immediately found the engineer who accompanied the team. After repeated confirmations, he told me: "There is definitely no problem with the fuel gauge, this situation will indeed exist." ”
According to the engineer, the reason why the 100-kilometer journey table shows that the endurance has only dropped by 1 kilometer is because this section of the road has gone downhill for the majority, and the overall altitude has dropped by almost 500m. So in most cases, the engine is actually not involved in the work, and when going downhill and braking, kinetic energy recovery will also charge the battery backwards, so the meter range is basically unchanged, this number is the real remaining mileage.
In this way, the road to come is somewhat "open a small stove" meaning. Therefore, on the way back, we deliberately adopted a more aggressive driving style, and this section of the road has also changed from downhill to mostly uphill, so that a relatively average fuel consumption reference can be obtained.
In the end, we traveled a total of about 200km, showing an average fuel consumption of 6.2L, and the endurance dropped from the starting 310 to 220km. So, the fuel gauge is really no problem, it is that this hybrid system is too provincial. And this time we test drive this time, which makes people think that the "fuel gauge is broken", is the new Geely Xingyue L Thor Hi · X Hybrid Edition.
Save fuel without sacrificing power
Thor Hi · X redefines the hybrid technology label
Before last year, the domestic hybrid car market can be said to have been dominated by the Japanese. Both Toyota's THS and Honda's i-MMD have technology labels that have shocked the industry. However, for traditional oil-electric hybrids, although it can provide good fuel economy, this is often achieved at the expense of vehicle dynamics.
It is not difficult to find that most of the models on the market that use oil-electric hybrid have efficient engines and motor support, but in terms of power performance, it is actually a little worse, especially in the case of power loss, energy consumption and NVH performance is even worse than the fuel version. Therefore, until now, in the field of oil-electric hybrids, power performance and fuel economy are still an antagonistic topic.
However, The Gilly Star crosses the L Thor Hi · The arrival of the X hybrid version broke this situation. Formally, The Geely Star crosses the L Thor Hi · The X hybrid version uses a similar logic to the Japanese hybrid. But the difference is that in Thor's Mind, Hi · In the X hybrid system, Ji utilizes the DHE15 hybrid special engine, which is also the world's first mass-produced supercharged direct injection hybrid special engine.
Compared with the previous Japanese hybrid self-priming engine featuring the Atkinson cycle, this 1.5T engine specially developed for hybrid uses a supercharged Miller cycle, combined with a series of efficiency enhancement technologies such as high-pressure direct injection, supercharged intercooling, and low-pressure EGR exhaust gas recirculation, which increases the thermal efficiency of the engine to 43.32%, breaking the world's record for the highest thermal efficiency of mass-produced hybrid engines.
While bringing super high thermal efficiency, Hoshikoshi L Thor Hi · The system of the X oil-electric hybrid version also has a comprehensive power of 180 kW, a comprehensive torque of 540 N·m, and an acceleration of only 7.9 seconds from 100 km/h. It is worth mentioning that the high thermal efficiency area coverage of this DHE15 hybrid special engine is close to half, and the liter power and torque are far more than the Japanese hybrid. Thanks to such excellent fuel economy and power performance, Hoshigoku L Thor Hi · The DHE15 hybrid special engine on the X hybrid version also won the title of the 2021 "China Heart" Top Ten Engines, which can be said to redefine the highest standard of hybrid engines.
The same is the hybrid
Thor Hi · X can "be one stop higher"?
Of course, the core of efficient hybridization is not just as simple as having an efficient engine, if there is no good traditional system to match it, it is likely that the oil saved by the engine will eventually be wasted on the transmission.
So, in addition to the ultra-high-efficiency hybrid special engine, Thor Hi · Another of the biggest differences in the X-Hybrid system is in its drivetrain. Different from the common E-CVT, 1st gear DHT, and 2nd DHT on the market, Hoshikoshi L Thor Hi · The X Hybrid Edition is equipped with the world's first production 3-speed hybrid electric drive transmission, the DHT Pro.
As the name suggests, first of all, this set of DHT Pro has 1 or even 2 more gears than other hybrid models in gears, and this advantage is also obvious, that is, different modes such as parallel, series, and direct drive can be achieved in any speed range through more gears, so that the engine and motor are in the efficient range at all times.
During the test drive, Hoshikoshi L Thor Hi · X hybrid version at 20km/h can let the engine intervene in the output, in the low-speed start can bring comparable to the acceleration of the tram; and in the commonly used 40-80km/h speed range, DHT Pro electric drive transmission can be hung on 2 gears, at this time the transmission efficiency in the oil-electric series mode can reach about 90%; and in the process of high-speed driving, DHT Pro electric drive transmission hangs on 3 gears, can achieve up to 97.5% transmission efficiency, and through its unique 3-speed variable speed increase torque function, Gear can also be lowered during sharp acceleration to provide greater torque output.
So to sum up simply, the DHE15 hybrid special engine is the Hoshigoku L Thor Hi · The X Hybrid Edition brings an ultra-high thermal efficiency power source, and the DHT Pro transmission keeps this highly efficient engine in the efficient operating range in most cases, and the combination of the two will naturally save fuel without sacrificing power. This actually explains why in the more than 100-kilometer test drive process, the number of engine starts is countless, and such fuel consumption performance is naturally logical.
Oil-electric hybrid takes the lead
Thor Hi · X Builds the "Strongest Hybrid System"
Since last year, the domestic hybrid technology represented by BYD has begun to show its prominence in the market, and its hot market performance has initially formed a situation of confrontation with Japanese hybrids. At the market level, although the Japanese hybrid was launched earlier and more well-known, due to its relatively high price in China, the Japanese hybrid did not actually promote the growth of the entire hybrid market.
Take the sales of new energy vehicles in the past two years, for example. In 2020, domestic sales of new energy vehicles reached 1.367 million units, including plug-in hybrid models including range extenders, of which 251,000 units; by 2021, retail sales of new energy vehicles reached 2.989 million units, and sales of plug-in hybrid models, including range extenders, reached 545,000 units, an increase of 171.2% year-on-year. It is not difficult to see from the data that the growth rate of hybrid has exceeded that of pure electric models, and it is the entry of independent brand hybrid technology last year that has really made the market bigger.
So, in this context, Geely's Thunder God Intelligence Hi · X hybrid technology chooses to take the lead with oil-electric hybrid, which is obviously aimed at the Japanese hybrid market. Compared to the Japanese hybrid, Ray's Mind Ishi · X Hybrid has achieved comprehensive transcendence in terms of power performance, fuel economy and driving texture. And the most important point is that on the price level, Hoshikoshi L Thor Hi · The X hybrid version is much closer to the people than the Japanese hybrid.
Therefore, in today's Japanese hybrid technology "stagnant", it is obviously a wise choice to cut in from the angle of oil-electric hybridization. Of course, Ray's Mind Ishi · X hybrid does not stop at the stage of oil-electric hybrid. In the future, under this technology platform, there will also be HEV, PHEV, REEV and other hybrid systems and 400V/800V electric drive solutions, and at that time, Raytheon Hybrid will also form the strongest hybrid system to achieve comprehensive coverage of hybrid technology.
There is no doubt that after the CMA architecture and the SEA vast architecture, Gilly Ray's divine intelligence is Hi · The arrival of the X-hybrid once again built a technical wall. Under the strong technology platform and rich product matrix, Raytheon Power will also become a new hope to promote the development of the hybrid vehicle market.
