Vehicle retarders have become the standard configurations in some developed countries, while the installation rate of vehicle retarders in China is very low compared with developed countries. Currently the installation rate of vehicle retarders used in middle and large-sized passenger cars is about 80%, and the installation rate of vehicle retarders in heavy-duty trucks is less than 5% on account of safety awareness and retarder cost. Although new national standards released in 2012, heavy-duty truck retarder market is not optimistic as expected
In 2013, the sales revenue of vehicle retarders in China was about CNY 2.1 billion. With the perfection of relevant national policies in the future and the increase of safety awareness, heavy-duty truck retarder market may be opened in the year of 2016.
In China, the main passenger car used retarders are eddy current retarder and hydrodynamic retarder. Domestic eddy current retarders are mostly concentrated in the low-end market, while Telma, Voith and other foreign-funded enterprises occupy the medium and high-end retarder market. With the increase of localization of foreign products, the product line will extend downward; while domestic enterprises started to enter the high-end product market; the competition between China and foreign counterparts become fiercer, especially in the medium-end retarder market.
As for the technology aspect, eddy current retarders are common in China's market at present, accounting for 80% of the market share, and mainly used for medium and large-size passenger cars; while hydrodynamic retarders occupy about 20% of the market share and have obvious performance in trucks.
