The Audi BAR is a 4.2L naturally aspirated V8 gasoline engine from the Volkswagen-Audi Group’s EA824 series
(actual displacement: 4,163 cc; commonly referred to as the 4.2 FSI). It was produced from approximately 2005 to 2010.
It belongs to Audi’s new generation of all-aluminum V-series engine family (sharing a modular design philosophy with the 3.2 V6 FSI),
featuring a 90° V8 configuration, direct injection (FSI), dual overhead camshafts (DOHC) with 32 valves, and fully variable valve timing.
The BAR version is a comfort-oriented tuning variant designed for large SUVs (as opposed to high-revving sport versions like the BNS in the RS4).
It delivers strong power and ample low-end torque, and was primarily installed in the first-generation Audi Q7 and Volkswagen Touareg.
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.
