What owners say
Q5
Overall
Mixed sentiment with a clear dichotomy. The vehicle is consistently praised for its superior driving dynamics, handling, and refinement compared to mainstream and some luxury competitors. Owners frequently describe it as "fun to drive," "super quiet and smooth," and possessing a solid, tank-like build quality.
Best version to buy
The 3.0T supercharged V6 engine (found in pre-2017 Q5 models and in the SQ5) is very frequently recommended over the 2.0T four-cylinder for its power, refinement, and perceived reliability. For newer generations, the plug-in hybrid Q5 e is suggested as a high-feature, powerful, and efficient alternative to the performance-oriented SQ5.

X3 M

Owner sentiment is sharply divided, heavily dependent on the specific powertrain and ownership expectations. The high-performance X3 M and X3 M Competition models are praised for their exceptional power, engaging driving dynamics, and status as a practical yet thrilling performance SUV.
