“We love this family SUV. Just beware it is a diesel engine, you might hit some issues (DPF) down the road but other than that it is rock-solid, comfortable and provides the best ride quality you can find for the money. Oh, and fuel economy too!”
2014 Mercedes-Benz GL-Class: What's New, Specs & Features
Last updated August 4, 2026

The most important 2014 change is that automatic emergency braking became standard on the GL 350, GL 450, and GL 550. Otherwise, this is a light update to the second-generation GL-Class, with a few technology and GL 550 styling changes but no redesign or new engines.
About the 2014 Mercedes-Benz GL-Class
Second-generation GL-Class (X166), introduced for 2013; 2014 is the second model year of that generation, before the 2016 rename and refresh to GLS.
Mercedes-Benz positions the GL-Class as a full-size luxury family SUV that does not ask buyers to give up comfort, safety, or road manners just because they need three rows. The core pitch is room for seven adults, a quieter and more polished drive than truck-based rivals, and a broad powertrain range that runs from long-range diesel efficiency to AMG performance. It is the brand’s big road-trip SUV first, with real cargo flexibility and advanced safety tech as major selling points.
For 2014, the GL 350 BlueTEC serves as the long-distance diesel model, while the GL 450 is the mainstream gas V8 version. The GL 550 adds navigation, leather, ventilated multicontour front seats, and a surround-view camera; the GL 63 AMG pairs seven-seat utility with a handcrafted 550-hp V8 and AMG-tuned air suspension.

2014 Mercedes-Benz GL-Class Reviews
What owners are saying about the 2014 Mercedes-Benz GL-Class.
“The GL 450 is exactly what my family needed. Plenty of room for people and pets. The ride is wonderful and the vehicle is quite powerful. We took it skiing a few weeks ago and it handled snow and ice really well. Definitely a step up from my older ML350. Loving the car so far.”
