The short answer
The BMW X5 offers fuel economy, while the Mercedes-Benz GLE excels at power instead. Choose the BMW X5 if you prioritize fuel economy in daily driving, or the Mercedes-Benz GLE if power matters more for your needs. Both are covered by real owner reports on CarWizz.
Overall
Sentiment is mixed and heavily dependent on the specific generation, powertrain, and ownership approach. For the current G05 generation (2019+), the inline-six (B58) powertrain is very frequently praised for its performance and noted reliability, with some owners calling it "super reliable" and "the best inline 6 in the world." The driving experience is consistently highlighted as a major strength, described as "performance oriented" with superior ride, handling, and road feel compared to key competitors. However, significant criticism is directed at the plug-in hybrid variant (50e), with one detailed owner report citing a "terrible" experience involving multiple, repeated drivetrain failures and extensive dealership visits.
Best version to buy
Insufficient owner data available to declare a single "best" version. Strong, recurrent praise is directed at models equipped with the B58 inline-six engine (e.g., xDrive40i), which is lauded for its reliability and performance.
Known issues
Overall
Mixed sentiment with a clear generational divide. Feedback on the 2020-2023 generation (W167) is generally positive, with owners praising its comfortable, cloud-like ride, stunning and spacious interior, ample power from six-cylinder engines, and overall refinement as a luxury family cruiser. However, significant and recurrent criticism is directed at the 2024-2026 model years, particularly regarding severe electrical and software reliability issues.
Best version to buy
For the 2020-2023 generation, the GLE 450 with the inline-six engine is frequently cited as the sweet spot, offering ample power without the extreme cost of the AMG models. The AMG Line package is appreciated for its aesthetics.
