The short answer
Based on available data, the BMW M2 comes out ahead of the Audi RS3 on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
The sentiment is strongly positive, centered on the vehicle's unique and highly praised 2.5-liter turbocharged 5-cylinder engine (codenamed DAZA). This engine is consistently described as "iconic," "special," and delivering a "symphony" of sound, forming the core emotional appeal of the RS3. The car is recognized for its "crazy rally car performance," potent acceleration, and competent handling, with the torque-vectoring rear differential noted for improving agility.
Best version to buy
Insufficient owner data available to designate a specific model year or trim (e.g., Performance Edition) as the consensus "best version." Discussion indicates the facelifted model (post-2024/2025) may have improved programming, but this is not corroborated by detailed ownership reports. The primary differentiator emphasized is the 8Y generation (2022+) with the updated 2.5T engine and torque-vectoring rear differential over the previous 8V generation.
Known issues
Overall
Sentiment is highly positive, with owners praising the M2 as a focused, engaging, and practical performance car that offers a compelling blend of power, handling, and daily usability. The F87 generation (2016-2021) is frequently lauded for its balance, with the original N55-powered model noted for its lighter weight and the Competition (S55) model for its increased power and track capability. The newer G87 generation is acknowledged as a more powerful and technologically advanced successor, though some feedback suggests it feels larger and heavier.
Best version to buy
Insufficient owner data available to declare a single "best" version, as preferences are split by generation and priority. For the F87 generation, the lighter original (OG) M2 is prized for its nimbleness, while the M2 Competition is favored for its S55 engine's increased power and track readiness.
