Summary

The Mercedes-Benz gls 500 4MATIC (2018) is rated by experts for excellent performance (4.9s 0-100 km/h) thanks to the V8 biturbo M278 engine, exceptional comfort (7 seats) and premium build quality. The main downsides are the very high fuel consumption (15.6 L/100km), the difficult to drive size in the city and the ongoing reliability problems associated with the M278 engine. Common problems reported with this engine include oil leaks (especially from the oil cooler and the delivery chain box), bumpy shaft regulator defects, and problems with the air suspension system.
