The Audi CLX series (including derivative models such as the CLXA and CLXB) consists of 2.5L FSI naturally aspirated V6 engines specifically designed
by the Volkswagen/Audi Group for mid-to-large-sized models with
longitudinal platforms, such as the C7-generation Audi A6L and A7:
Replacing the older BDW: The CLX was initially developed to fully replace the BDW 2.4L multipoint fuel-injected engine used on the previous-generation
C6 platform, incorporating FSI direct injection technology
and the AVS (Audi Valvelift System) variable valve lift system.
Technical Highlights: Featuring a 90° V6 aluminum cylinder block paired with high-pressure direct injection and the AVS system,
it ensures exceptionally smooth and quiet V6 operation while significantly
improving fuel economy and responsiveness.
Our products are exported to various parts of the country, and the customers we have worked with have received unanimous praise.
The company has invested over 20 million yuan in high-end remanufacturing equipment imported from abroad and a first-class production
team in the country. Our warehouse has a total area of over 8000 square meters, with scientific management and sufficient supply of goods.
