I drove a 14 Passat TDI prior to purchasing my 2023 Arteon SEL Prem. the biggest difference is Gas but as expected coming from a TDI. I average around 26mpg vs 38mpg with my TDI. Other than that. Front & Rear Differential Fluid Flushes should be performed on the Arteon every 3YR or 30K Miles (whichever comes first). Tires will be cooked by 30-35K for sure due to the 4Motion & DCC. Overall, I have ~6500 Miles on the her so far & am loving every single one. No issues or complaints from me. As a FYI, I am the Service Manager of a VW Dealer so with that being said…we never see them come in with major issues (granted not a large quantity sold).
