Power and torque increased by 20%, fuel consumption reduced by 15%, BYD released Xiaoyun 1.5T flagship

On July 24, 2020, Beijing time, the 23rd Chengdu International Auto Show officially opened. At the auto show, Fudi Power released its new fuel power brand "Xiaoyun" and its first 1.5T high-power powertrain. It is understood that the 1.5TI high-power powertrain will be first equipped with BYD's B-class SUV Song PLUS, which will be launched in September.

In terms of power, Xiaoyun's new 1.5TI high-power powertrain has a maximum power of 136kW and a maximum torque of 288 Nm. The power and torque have increased by 20%, reaching the leading level in the same class in the industry.

In addition to power, I believe everyone is most concerned about the economic aspect, after all, this is the two sides of the same coin of the powertrain. It is understood that the thermal efficiency of Xiaoyun's new 1.5TI can reach 35%, and the fuel consumption per 100 kilometers can be reduced by 15%. From this perspective, it can be found that the economic cost of Xiaoyun's new 1.5TI is still very low.

In terms of NVH, in response to the demand for high-quality vehicles, Xiaoyun's new 1.5TI high-power powertrain reduces the power system noise from the source. In the full-speed range, the noise value has reached the industry-leading level, and in the commonly used speed range, it has refreshed the industry's best level in the authoritative database. At the same time, thanks to the assistance of the new 7-speed wet dual-clutch automatic transmission, the powertrain noise of the vehicle is further reduced in driving. The measured powertrain noise is 2-4 decibels lower than that of joint venture products of the same level at full speed.

In terms of reliability, under Fudi Power's unique and rigorous testing system, Xiaoyun 1.5TI has withstood a durability test that is twice the national standard, and has reliability far beyond imagination. It is particularly worth mentioning that in response to the various needs of Chinese users for smooth, economical, reliable and durable transmissions, the new 7-speed wet dual-clutch automatic transmission has also been fully upgraded, focusing on improving the smoothness of low-speed and frequent shifting. While the transmission efficiency is as high as 95%, the durability is 25% higher than the average design life standard of traditional AT transmissions.

Official data shows that Fudi Power was officially established in 2019 and was originally affiliated with BYD's powertrain division. Since 2003, it has been committed to the development of powertrain and new energy overall solutions. As early as 2008, Fudi Power launched the world's first mass-produced plug-in hybrid powertrain system and won the China Patent Gold Award; in 2011, the first domestic 1.5TI supercharged direct injection engine was mass-produced and launched; in 2013, the first domestic wet dual-clutch automatic transmission was launched. Fudi Power has achieved industry leadership in the research and development and application of many power products.

The continuous expansion and maturity of Fudi Power's global R&D system has gradually gathered more global wisdom. In the process of developing a new generation of power products, Fudi Power has carried out in-depth cooperation with AVL, FEV, Ricardo and other world-class power R&D institutions in multiple fields such as performance simulation, testing and NVH engineering, and has forged top-quality power with comprehensive and excellent performance based on the world's top technical standards.

Adhering to the concept of high starting point and global vision, Xiaoyun's new 1.5TI high-power powertrain has achieved epoch-making advancement in efficient intake system, advanced combustion system, and intelligent thermal management system technology. The new engine also uses a number of technologies such as dual-flow turbocharger, electronically controlled turbine blow-off valve, and mid-mounted VVT mechanism, which improves its low-speed torque performance by 36.7% and low-speed responsiveness by 40%, making it more suitable for urban road conditions and frequent start-stop usage scenarios. At the same time, under the premise of ensuring high power response performance, the application of light Miller cycle technology, combined with high tumble ratio intake duct and 350bar high-pressure direct injection system, helps to achieve high fuel efficiency and further improve emissions and fuel consumption.

Not only has the engine technology been greatly improved, but the new 7-speed wet dual-clutch automatic transmission has also undergone a number of technical upgrades to meet the various demands of Chinese users for smooth, economical, reliable and durable transmissions. This has greatly improved the control accuracy and smoothness of the actuator, and achieved a leap in the transmission's responsiveness and shifting quality under different working conditions.

After reading the above, everyone must be eager to experience Xiaoyun's new 1.5TI high-power powertrain. However, according to the official introduction, Xiaoyun's new 1.5TI high-power powertrain will be first installed in Song PLUS. According to the plan, Song PLUS will be launched in September with a price of 120,000-150,000 yuan. Impatient friends still need to wait patiently for more than a month.
