Haval H6 is famous in the auto market, and its annual sales of bicycles (SUV) are stable and ranked first Among them, in 2020, H6 sold a total of more than 360,000 units. As the absolute trump card of Great Wall Motors, H6 will naturally take the lead to "enjoy" the most advanced technology of car companies. For example, the third-generation H6 launched last year was the first model of the Lemon platform, and the H6 2.0T four-wheel drive version launched later is also the first time. Use Great Wall’s 4N20 engine.
However, the recently released Haval Chitu , which seems to be the "little brother" of H6 (the length is less than 4.5 meters), but with a more advanced 1.5T engine, Haval Chitu achieved 7.7 "Broken 100" in seconds. This can't help but worry people. Does H6 have to lose its "main palace status"?
What is the difference between the first, second and third generation H6?
In the Great Wall Motor product line, there are currently two different models of engines with a displacement of 1.5L in service, namely GW4G15F and GW4B15A. Although they are both "with T" versions, the book data is quite different. The former is 150 hp/210 Nm, used in H4, M6, H6 Coupe, F5, first love and other models, the latter is 169 hp/285 Nm, used in the third-generation H6, Big Dog, F7 and other models.
The first-generation Haval H6 sports version
Of course, the two engines are not only different in data. This 4G15F engine has been used on the first-generation H6 as early as possible. Regarding the EFI system, Great Wall Motors will not have complete independent development capabilities by then, so this 1.5T EFI still has some traces of reverse (mainly Toyota).
the second generation of Haval H6
to the second generation of Haval H6,Great Wall Motors has developed this GW4B15 engine with independent intellectual property rights. It not only adopts mainstream technologies such as in-cylinder direct injection, CVVT, and integrated exhaust, but also is equipped with a CVVL valve lift control system, bringing the technology of domestic engines into a leap. Push the level to a new level.
The third-generation Haval H6
The GW4B15A engine used on the third-generation H6 is an improved version of the previous version. The injection pressure has been increased to 350Bar, and the CVVL system has been retuned. Although the book data is the same, The high-speed burst and fuel economy of the whole machine have been improved. At present, this GW4B15A engine is the main force of Great Wall's SUV models and is widely used.
Where is the 1.5T engine of Haval Chitu?
arrived at this Haval Chitu, the car is equipped with a further upgraded GW4B15C engine, from "A" to "C", not only the book data increased to 183 horsepower (135 kW) / 275 Nm, but also equipped with Numerous hardcore new technologies, including VGT supercharger, two-stage variable displacement oil pump, 350bar direct injection, and electronically controlled turbo pressure relief valve, have more explosive power than H6.
Among many new technology applications, the most useful for improving performance is the VGT supercharger and the electronically controlled pressure relief valve. The former is the variable section turbocharging technology, which can be automatically adjusted according to the engine speed and power requirements. The volute surface diameter of the supercharger takes both low-rotation response and high-rotation burst into consideration, while the electronically controlled pressure relief valve controls the inlet/exhaust pressure through the solenoid valve, which can control the intake more freely than the vacuum tank pressure relief valve Pressure not only responds faster, but also allows the engine to continuously output 275 Nm of large torque on a wider peak torque platform.
According to the official data, the Haval Chitu equipped with 1.5T+DCT powertrain, coupled with the ejection start mode, its 0-100km/h acceleration time is only 7.7 seconds, which is better than the third-generation H6 It is much more "sturdy". This performance is already close to that of sports cars such as Honda Civic and Hyundai Festa.
"The King of Virtual Standard" Changan UNI-T 1.5T
As a comparison, the same main high-performance Changan Blue Whale NE 1.5T engine (180 horsepower/300 Nm), measured on UNI-T 0-100km The /h acceleration time is 9 seconds away, and it is dubbed the "virtual standard king" by netizens. The Chery F4J16 1.6T (197 horsepower/290 Nm), which has always been irritable, takes more than 8 seconds to drive on the Xingtu LX to "break the hundred."
What other conditions are needed to achieve "breaking 100" in 7.7 seconds?
Thanks to the in-depth optimization of the body and chassis architecture of the lemon platform, the "weight loss" plan of the third-generation H6 is undoubtedly very successful, and this feature is even better on the Haval Chitu The weight of the high-end equipment is controlled at 1499kg, which is 50kg+ lighter than the H6.
In terms of size, the length, width, and height of the new car are 4450/1841/1618mm, and the wheelbase is 2700mm. The size is significantly smaller than the H6 by one size, and it looks more sophisticated. In addition, Chitu is also equipped with 18-inch multi-spoke wheels and 225/55R 18 tires. The low aspect ratio wide-side tires help improve the vehicle's grip performance and prevent skidding at the start.
Looking for aerodynamic features on an urban SUV is undoubtedly a rogue, but Great Wall Motors still equips this Chitu with front and rear diversion grooves, black exterior mirrors and large-size rear wing, with a large-diameter straight waterfall The front grille makes the vehicle look very combative.
What are the highlights of Haval Chitu’s "saddle"?
Obviously, this Chitu is a sporty SUV product. In addition to the aerodynamic kits mentioned above, the new car is also equipped with powerful LED headlights, LED daytime running lights and round shapes. The fog lamp adopts a split design,Set against each other with the trapezoidal lower bumper, the front face looks very impactful as a performance car.
Coming to the side, the new car also adheres to the line and surface outline of a sports SUV, with a slender cabin and a convergent tail, coupled with a straight upright waistline, which fully highlights the sporty atmosphere.
Sitting in the cockpit, the pure black interior color matching, with green decorative strips and silver metal panel decoration, creates a very combative interior atmosphere. The seat part also uses suede elements, and the diamond-cut line design is also very dynamic.
As a fashionable car specially prepared for young people, Haval Chitu will naturally not disappoint users in terms of trend elements, including full LCD display on the instrument panel, 12.3-inch large central control screen, crystal electronic gear lever, etc. absence. At the same time, the surrounding cockpit layout further enhances the human-computer interaction experience of the main driver.
In terms of intelligent configuration, voice interaction, electronic handbrake, and one-button start are all "basic operations". The new car is also innovatively equipped with functions such as identity recognition, emotion perception, and fatigue driving reminders. In addition, including the hollow storage compartment under the electronic barrier, Haval Chitu also designed as many as 26 storage spaces for users.
Summary
As a sports SUV, the Haval Chitu has a profound impact with its 7.7 seconds "breaking 100" acceleration. In addition, the size is smaller than H6, and its price is expected There will also be a slight advantage. It is difficult for such a compact SUV rookie to shake the position of the H6, but it is still very attractive to young people who are pursuing performance control. As far as the market is concerned, judging from the current progress, the car is expected to be officially launched at the Shanghai Auto Show in April this year. We will wait and see how the domestic SUV with a performance close to that of the Honda Civic will perform.
