As the current SUV sales crown of SAIC Roewe, RX5 has won the favor of many Chinese people with its high cost performance since its launch in 2016, and it can also gain a firm foothold in the highly competitive market of compact SUVs. According to the official plan, the new Roewe RX5 (officially known as the third generation) is expected to be listed in the second quarter of this year.
The new car is not only equipped with a new design, but also lengthened, and the wheelbase has reached the 2765mm of the leapfrog class, which is more advantageous than the 2738mm of the third-generation Haval H6. As the originator of the intelligent network boom that set off that year, the new Roewe RX5 is naturally exempt from inspection in terms of intelligent technology.
So what is the focus of the upgrade of the replacement? The answer lies in the SAIC Blue Core 1.5T engine, which has previously won the "Top Ten Engines of China's Heart", and on the new Roewe RX5, this engine will be further evolved, from combustion optimization, gas exchange, heat management, friction reduction and NVH and other five aspects of upgrading, it can be said that all the technical essence of SAIC.
With a maximum torque of 300 Nm, it does not lose the Honda Earth Dream
First of all, the SAIC Blue Core 1.5T engine adopts a new generation of SGCS combustion system, with a 350bar high-pressure fuel injection system and an electronically controlled variable-section turbocharger, which can burst out a maximum power of 138kW and a maximum torque of 300N·m. Compared with the current engine, the data has improved. And even the EA211 EVO1.5T that benchmarks Volkswagen or the Honda Earth Dream 1.5T is not lost.
Thermal efficiency is up to 40% and fuel consumption is only 6.0L/100km
Theoretically, the higher the thermal efficiency of the engine, the less fuel is consumed by the same power output, and the more fuel efficient it is. The current oil price market, I think everyone knows. Thanks to electronic water pumps, Fast VVTs, pendulum dual-mass flywheels, continuous variable oil pumps, water-cooled intercooling systems, journal size optimization, anti-friction coatings and many other technologies, the new Roewe RX5's 1.5T, friction losses are 21% lower than the previous generation.
At the same time, the maximum thermal efficiency of the engine has also increased to nearly 40%, as a reference, the thermal efficiency of the Honda Earth Dream 1.5T is 38%, and many people expect the Volkswagen EA211 EVO1.5T to be only 37.5% thermal efficiency. According to official disclosures, the fuel consumption of the new Roewe RX5 equipped with the engine is only 6.0L/100km (NEDC), which is significantly lower than the current 6.8L/100km.
NVH optimization, driving quality will be improved
In terms of NVH, the overall noise of the new BlueCore 1.5T engine will be further optimized through the reinforcement of the body structure and the lightweight design of the crank linkage mechanism, as well as the application of acoustic wrapping in key parts such as timing cover and fuel system.
The NVH performance of the car is a comprehensive performance to measure the quality of the car design and manufacturing, is the embodiment of the quality of a model, NVH upgrade, which means that the new Roewe RX5 driving quality will be further improved.
One engine rolled off the production line in more than 1 minute, with an annual production capacity of 300,000 units
The 1.5T of the new Roewe RX5 is the first product independently developed by SAIC Motor and launched by SAIC Zhengzhou Engine Plant, according to the official disclosure, the first phase of SAIC Zhengzhou Engine Plant project can achieve an average of one engine off the production line in more than every minute, achieving an annual production capacity of 300,000 units.
Thanks to the blessing of world-class parts suppliers such as Bosch BorgWarner, Valeo, and Eaton with the world's leading technology, plus more than 60 special tests and 5 million kilometers of vehicle testing, the quality can be guaranteed.
Write at the end
As we all know, whether it is a family car or an SUV, many manufacturers are now vigorously promoting 1.5T engines. The new Roewe RX5 can upgrade the existing 1.5T and is also an effective way to improve competitiveness. It is worth mentioning that the DM217-speed wet dual-clutch transmission matched with this 1.5T engine has also won the "World's Top Ten Transmissions". This combination of double ten power makes people look forward to the performance of the new Roewe RX5.
