All Great Wall Motors and Haval vehicles will receive the Hi4 system as early as 2024. What are its benefits?
On May 22, at a Great Wall Motors press conference, Li Ruifeng, the company’s director of development, revealed that by the end of 2024, all of the automaker’s models will be equipped with Hi4 technology as standard.
Hi4 is a new hybrid system developed by Great Wall Motors. Hi4 is short for Hybrid Intelligent 4 Wheel Drive. It is a series-parallel hybrid system, which means that the electric motor can operate independently of or in conjunction with the gasoline engine. The Hi4 system uses a gasoline engine and two electric motors. The Hi4 system is also equipped with a lithium-ion battery that gives the car a range of up to 100 km on electricity alone.
The Hi4 system works by automatically switching between a gasoline engine, an electric motor, or a combination of the two. The system uses various sensors to determine the best mode of operation for the current driving conditions.
For example, if the car is moving at low speed, the electric motor will be used. The petrol engine will be used if the car is traveling at high speed. And if the car accelerates, the two engines will work together to provide maximum power.
The Hi4 system has a number of advantages over traditional hybrid systems. First, it is more efficient because the electric motor can run independently of the gasoline engine. Secondly, it is more powerful because the two motors can work together to provide maximum power. Thirdly, it has a longer range on electricity only, because the battery is larger.
Chen Shujiang, deputy chief engineer of the Great Wall Motors hybrid system, said that Hi4 technology breaks the traditional form of hybrid twin engines, mainly centered on the front axle. This is a new configuration with three motors distributed over two axles, so that one motor on the front axle can be used separately in different working conditions.
Another advantage of the Hi4 system, according to Mr. Shujiang, is that a series-parallel all-wheel drive electro-hybrid architecture can be manufactured without increasing the vehicle’s production cost and purchase price.
The new Hi4 technology also uses iTVC (Intelligent Torque Vector Control) to adjust the distribution of torque and power between the front and rear axles, preventing loss of traction and wheel spin on slippery surfaces.
The first model equipped with the new Hi4 technology was the Haval Xiaolong Max crossover.
We are waiting for the new Model 3 and Model Y: Tesla sharply reduces the prices of its best-selling models
Tesla this year is the most likely to change prices for its models. This time around, the prices of Tesla’s best-selling vehicles have come down, with the biggest drop exceeding $3,000.
Model Y prices were already slightly lowered in the second half of May after being raised earlier that month. Now they have been reduced even further. The Model Y Dual-Motor Long-Range AWD is $55,430, $560 less than before.
The rear-wheel-drive Model 3 received a $3,210 price cut, to $39,530. Tesla indicates on its website that the same model is eligible for up to $3,750 in federal tax credits. The automaker promises to deliver cars during June-July.
According to one version, the automaker just wants to increase its sales and deliveries, so it reduces prices. Strong quarterly results are becoming a hallmark of Tesla.
It’s likely that Tesla is doing its best to liquidate stock in preparation for releasing updated models. Tesla is rumored to be working on an updated version of the Model Y, codenamed Juniper. The car is expected to go on sale in 2024.
There are also rumors about the imminent release of the Model 3 update, codenamed Highland. It can be presented at any time.
Honda Accrod in a new way. Honda Inspire 5m sedan unveiled
In China, the flagship Honda Accord sedan has a sibling called the Inspire, manufactured by Dongfeng Honda. In fact, Inspire – the same Accord, only with a slightly different appearance.
The Inspire has its own grille, bumpers and taillights. The length of the car is 4979 mm: the Inspire is only 1 mm shorter than the Accord. There are slight differences in the interior design: the Inspire has separate ventilation deflectors and a different climate control unit. The choice of transmission modes in Inspire is carried out by buttons, not by a lever.
The power plants have not been declassified, but the inscription e: PHEV on the trunk lid indicates that the Inspire is a plug-in hybrid. Probably, there is the same power plant as the Accord: with a 2.0-liter internal combustion engine and an electric motor with a total power of 206 hp, as well as a traction battery with a capacity of 17.7 kWh. However, it is possible that there will be a purely gasoline version with a 1.5-liter turbo engine with 192 hp.
Inspire will go on sale in China in June, and prices will be announced at the same time.
Why did the first Chinese aircraft COMAC C919 pass through the “water gate” and what does the BYD car have to do with it: new details about the historical event have appeared
On May 28, the newest narrow-body medium-haul airliner COMAC C919 made its first flight on flight MU9191 from Shanghai to Beijing, as we have already reported. Now, BYD has made an additional announcement.
Sometimes passengers of airliners can observe an unusual picture when the plane is doused with water from fire hoses. This is an international tradition, which is treated very reverently. Aircraft are poured over in different cases, for example, if a new airport was built and put into operation in a settlement, then the first aircraft is passed through the “water gate”. The same applies to aircraft that have flown for the first time on a new route or simply models that have made their first flight.
Netizens noticed that a red BYD Tang was standing next to the fire truck. From another angle, a yellow BYD Tang was visible. The manufacturer confirmed that BYD was honored to take part in the historic event, and its vehicles helped serve the first flight of COMAC C919.
Technology shows the strength of our country. BYD Tang welcomes C919! Congratulations on the successful first commercial flight of the C919 and respect for the creators of the aircraft and Chinese technology. Respect to those who work hard to open the way for our country.
