The short answer
Based on available data, the Cadillac Escalade comes out ahead of the Audi Q8 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
Mixed sentiment with a clear generational divide. The gasoline-powered Q8 (2019-2024) receives praise for its striking coupe-SUV styling, high-quality and comfortable interior, spacious cabin, and refined driving dynamics. However, it is heavily criticized for significant reliability concerns, particularly with major powertrain components leading to costly out-of-warranty repairs, and for very poor resale value.
Best version to buy
For the gasoline Q8/SQ8, the Prestige trim is frequently mentioned as the target for maximizing luxury features. For the performance-oriented SQ8, the Sport Package (including active roll stabilization and a sport rear differential) is specifically highlighted as a desirable option for enhanced driving dynamics.
Known issues
Overall
Sentiment is sharply divided by generation and powertrain, ranging from high praise for long-term durability in older models to significant frustration with reliability in newer ones. For the GMT400 (1999-2000) and early 2000s models, owner feedback is overwhelmingly positive, citing exceptional comfort, durability, and ease of home maintenance, with examples reaching 190k and 288k miles with basic upkeep. The sentiment for the 2016-2020 generation (K2 platform) is cautious but generally positive regarding the core 6.2L V8's power and capability, though overshadowed by very frequent, well-documented concerns over the Active Fuel Management (AFM) system lifter failures, which is considered a "ticking time bomb." For the 2021+ generation (including the 2025-2026 models), sentiment is negative regarding reliability, with very frequent reports of major engine and transmission issues, electronic failures, and poor build quality on brand-new vehicles, leading to significant buyer apprehension.
Best version to buy
For the 2021+ generation, a 2023 or 2024 model is recommended over newer 2025-2026 models due to reported engine issues in the latest production years. The ICE (internal combustion engine) model is frequently preferred over the Escalade IQ for its cargo space, Apple CarPlay/Android Auto retention, and fewer software teething problems.
