The long-awaited Chinese independent high-end sedan Hongqi H9 has been on sale in August this year. This car is available in 2.0T and 3.0T versions. It was sold at a price increase when it was first launched. Currently, this car is sold for The sales volume of nearly 3,000 units is still a good result among high-end brands. Compared with the 2.0T version, although the price of the 3.0T exceeds more than 400,000, many people are still interested. However, the manufacturer has been scheduling production, and it is a special model on the market. There are very few available.
In fact, the 3.0T engine installed in the Hongqi H9 has been installed on the Hongqi HS7 large SUV. It adopts a supercharged V6 structure with a maximum power of 248KW, a maximum horsepower of 337, and a peak torque of 445 Nm. Comparable to the BBA V6 engine in the same class, it still has a direct injection aluminum alloy structure and is filled with No. 95 gasoline.
But the same V6 engine is used in the Hongqi H9, but its parameters have plummeted. Although it is also a direct-injection aluminum alloy structure, the maximum power is only 208KW, the maximum horsepower is 283, and the peak torque is only 400 Nm, which is less than that of the Hongqi. HS7 is obviously different. Why is this?
It turns out that the "culprit" is this gearbox. The gearboxes of the two cars are different. The Hongqi HS7 uses the Aisin 8AT gearbox, while the Hongqi H9 is the latest 7AT gearbox put into production by FAW. The maximum torque that the fast-wet dual-clutch gearbox can withstand is only 400 Nm, so the peak torque of the 3.0T version of this car's engine is also limited to 400 Nm, which is really a pity.
Someone would like to ask what is the maximum tolerable torque of Aisin 8AT? This has different configurations depending on the engine model. For example, the 2.0T T8 power of the Volvo XC90 uses a turbocharged and mechanical double-supercharged engine-motor combination. The maximum power reaches 288KW and the peak torque reaches 640 Nm. , it is still an Aisin 8AT gearbox, so it will not be hindered by the gearbox.
Although the 3.0T power of Hongqi H9 is limited, the acceleration performance can still reach about 7 seconds. The chassis adopts a front-rear drive method, and the front suspension is a double-wishbone independent suspension. , the rear suspension is a trapezoidal control arm multi-link independent suspension, and is matched with suspension soft and hard, height adjustable functions.
Hongqi H9 has newly launched an extended version of the model named H9, with a wide chrome-plated straight waterfall grille, an illuminated Hongqi logo connecting the hood and the grille, and the bottom and sides The light strip still forms an integrated shape with the upper edge of the car lights. When the car lights are lit, they are highly recognizable and quite domineering.
The first thing that catches the eye is its red and white custom-made body. The wheelbase has been lengthened at the B-pillar, and silver metal plaques and H9 exclusive badges have been added, symbolizing the nobility of this car. identity. The body size of the Hongqi H9 has only increased by 203mm in length, with a length of 5340mm and a wheelbase of 3260mm. Although the rear section has not changed compared to the H9, due to the lengthening of the body, the overall length has been stretched, giving the visual appearance of a fastback. modeling. The design of the rear of the car is still a neat and square shape, with through-type taillights and the Chinese character "red flag" logo; the biggest difference is that the rear adopts a bilateral dual-exhaust layout.
The interior layout of the car is still very technological, with the same red and white splicing as the body. Everything within reach in the car is wrapped in soft leather, and the roof is made of Alcantara. Wrapped in genuine leather, with some textured decoration added to the oversized sunroof, and a starry sky roof design, the H9 is a true luxury sedan.
In fact, the main bottlenecks of domestically produced cars are still in the engine and gearbox. Although the engines are claimed to be independently developed, the parts are still from Bosch, Continental, Magna, etc., and although the gearbox has a patented dual-clutch The barrier is low, but torque tolerance is already reflected in luxury cars, so more research and development is still needed!
