Are Audi and Volkswagen engines the same?

[MacEmmanuel]

Audi engines and Volkswagen engines are the same, but there are differences in some functions and details. The specific differences are as follows: 1. Different systems: Audi engines are equipped with the AVS system, while Volkswagen engines are not. The AVS system is Audi's variable valve lift technology, which allows the engine to change valve lift according to different operating conditions. 2. Differences in engine cooling, noise reduction, and heat insulation: Audi is a high-end model of Volkswagen, with many optimizations in engine cooling, noise reduction, and heat insulation, while Volkswagen does not have these. 3. Different combustion methods: Audi engines use stratified combustion, a type of lean combustion, which makes power delivery smoother and fuel consumption more efficient. Volkswagen does not use this technology.
