Summary

The Mercedes-Benz gls 450 4MATIC (2025) is rated by experts as an SUV with exceptional comfort ("S-Class of SUVs") and large space (7 real seats). The Phase-II update brought an improved interior and technology (MBUX). The M256 Mild Hybrid engine is refined and offers a good balance between power and efficiency. The main weaknesses remain the large size for driving/parking, the problems with MBUX software (delay/freeze), the high complexity of the systems (especially the AIRMATIC air suspension) and reports of transmission problems in previous X167 models.
