A New Value Experience of "Four Savings"

Weichai Leads the Efficiency Revolution of Commercial Vehicles with a Long Technological Journey

In the field of commercial vehicle power, Weichai is writing a new chapter in the industry with its hardcore technology, where "fuel saving is the absolute principle". In 2024, Weichai ranked first in the industry with a domestic market share of 38.7% in heavy truck power. Data shows that in the first quarter of this year, the sales volume of Weichai diesel engines exceeded 200,000 units, consolidating its championship position and once again confirming the market's high recognition of the company's technological strength.

The foundation of this dominance lies in Weichai's consistent adherence to high-level scientific and technological self-reliance, strengthening the construction of independent innovation capabilities, and its decade-long "marathon" of scientific and technological innovation. In the past nearly 10 years, Weichai's R&D investment in the engine sector has exceeded 30 billion yuan, with a R&D intensity of over 6%, ranking among the top in the global industry.

Especially in recent years, based on high-intensity R&D investment, Weichai engines have been advancing towards larger horsepower and better performance. In 2015, the WP13 engine was launched, leading China's heavy trucks into a new era of 500+ large horsepower; in 2016, the first products of the H platform, WP9H/WP10H, independently developed and manufactured by Weichai, were launched; in 2022, the new H/T platform products were released, with the maximum horsepower reaching 680Ps; in 2023, Weichai's 17L displacement engine broke through the "ceiling" of large horsepower for heavy trucks.

Large horsepower is an important trend for efficient transportation in the logistics industry, and low fuel consumption is the winning magic weapon in the market competition. From 2020 to 2024, Weichai refreshed the world record of the thermal efficiency of diesel engine bodies four times in a row, increasing the thermal efficiency scale to 53.09%, and building a "moat" of fuel-saving technology that includes more than 200 patented technologies, pushing the fuel-saving benefits throughout the product life cycle to a new height.
