Overall
Sentiment is mixed and heavily dependent on the specific generation and powertrain. The naturally aspirated V8 models (B8/B8.5, 2013-2015) are praised for their thrilling, high-revving engine character, exceptional exhaust sound, and perceived build quality, making them desirable for driving enthusiasts. However, they are associated with very high and unpredictable maintenance costs outside of warranty.
Best version to buy
Insufficient owner data available to declare a single "best" version, as preferences are split by generation. Enthusiasts seeking engine character and sound strongly favor the B8/B8.5 generation with the 4.2L FSI V8.
