2013 Mercedes-Benz GL-Class Review

Reviewed by Automotive on

The 2013 Mercedes-Benz SUV lineup receives a modest overhaul in the 2013 model year. Four GL models are offered, including the G350 BlueTec, the GL450, and GL550, as well as the new AMG model, the GL63. The 2013 Mercedes-Benz GL-Class resides in a niche that is somewhere between the company’s smaller M-Class and the ultra-pricey Gelandewagen. The GL-Class offers strong performance and comfort in an attractive design that charges forward with a fuel-efficient diesel engine. Like everything else Mercedes-Benz does, the GL-Class represents engineering excellence and innovative design aimed at the discerning auto buying crowd who expect comfort and performance in equal measure.

New For 2013

For the 2013 model year, the Mercedes-Benz GL-Class stays cosmetically very similar to the preceding model, but adds an assortment of mechanical and interior updates. An AMG model is also introduced. The new features of the Mercedes-Benz GL-Class for 2013 include:

  • A new 3.0-liter, turbocharged, diesel six-cylinder engine is introduced in the G350 Bluetec
  • The GL450 receives a 4.7-liter, eight-cylinder engine
  • The GL550 retains its 4.7-liter eight-cylinder from the previous year, but sees it gently massaged for higher torque
  • Mercedes-Benz’s AMG lineup is given the GL63, boasting a 5.5-liter engine


Visually, not much is changed over the prior year for the 2013 Mercedes-Benz GL-Class. The shape and dimensions are fundamentally the same, and the overall aesthetic is only subtly advanced. The GL-Class is slightly more rounded in the corners and now complemented by L-shaped LED parking lamps and turn signal assemblies. Taillights are wider and now include LEDs. Nineteen-inch alloy wheels are standard, as are all season tires. A power lift gate door, intermittent rear wiper, and a roof rack are also included. A remote sunroof is also a standard amenity. Options for the outside of the 2013 Mercedes-Benz GL-Class include illuminated running boards, a trailer hitch, panorama sunroof, and 20-inch wheels.

Interior & Cargo

The first-rate interior included in the 2013 Mercedes-Benz GL-Class is well-outfitted, as one would expect from the German automaker. Infotainment amenities include an in-dash six-disc CD/DVD changer, SD memory card reader, Bluetooth, iPod integration, AUX and USB integration, and Sirius XM Radio. Also included is a 10GB Music Register for localized MP3 file storage. A Harman Kardon LOGIC7 surround system is also incorporated as standard. Other standard comforts include cruise control, a first aid kit, power steering, tilt and telescopic steering wheel, transmission and audio controls on steering wheel, and universal remote transmitter. Dual-zone climate control for driver and passenger, active charcoal air filter, sun sensor, real wood and leather trim, and leather upholstery are also standard features. Options include rear-seat entertainment, a heated steering wheel, three-zone automatic climate control, heated seats, and power EASY-ENTRY second-row seating.


Safety features of the 2013 Mercedes-Benz GL-Class are quite robust. Included are 13-way airbag protection, PARKTRONIC parking assist, Blind Spot Assist, PRE-SAFE and POST accident anticipation and mitigation, and a rear view camera. All safety features are incorporated in an advanced uni-body design for maximum impact-resilience. Other safety features of the 2013 Mercedes-Benz GL-Class include a four-wheel Anti-lock Braking System (ABS), brake assist, hill-start assist, Electronic Stability Program, trailer stability assist, and Mercedes mbrace mobile application. The mbrace app connects the driver with over 20 security and destination planning services. Run-flat tires are also incorporated into the design of the 2013 Mercedes-Benz GL-Class.

Driving Experience

All models of the 2013 Mercedes-Benz GL-Class are amply powered for most urban and even some off-road excursions. The GL350 BlueTec offers up to 240 horsepower, while the engine of the GL450 offers up 335 horsepower in non-turbo, and 363 horsepower when turbocharged. The GL550 ramps up to an impressive 429 horsepower. The new 2013 Mercedes-Benz GL63 AMG tops the power output list of the lineup, coming in at 550 horsepower. In all cases, the engine is paired to a seven-speed shiftable automatic transmission. ABS and traction control make the ride very stable for an SUV of this type.

In-cabin features are plentiful and make the GL-Class pleasant to drive. Comfortable and elegant seating, quality sound, and resulting low road noise make the driving experience outstanding. With diesel-based fuel efficiency, the Mercedes-Benz GL-Class is a strong offering from one of the foremost German automakers in history.
