KBB Editor's Overview
As the largest SUV to wear the 3-pointed Mercedes-Benz star, the luxurious GL-Class for 2015 delivers all the utility of a family-friendly SUV and combines it with the styling, performance and interior opulence of the finest S-Class sedan. The GL’s reputation for excellence is bolstered by impeccable build quality, enviable safety ratings and a sophisticated suspension that delivers one of the most comfortable yet dynamic rides of any full-size luxury crossover SUV. The big Benz offers a variety of powertrain choices including an all-new twin-turbocharged V6 and a fuel-efficient diesel. And, unlike many luxury SUVs derived from more mainstream platforms, the 2015 GL-Class shares no such pedigree. It’s pure Mercedes-Benz through and through, which is one more reason the GL-Class SUV is held in such high regard.

Driving It
Driving Impressions
Despite its large size, tall driving stance and tank-like solidity, Mercedes-Benz’s 2015 GL-Class SUV is an absolute joy to drive. The ride is comfortable and stable, complemented by a silent cabin and some of the most comfortable seats in any luxury SUV. From the driver’s seat forward, the big GL feels as if it were just another excellent Mercedes sedan, only revealing its true self after a glance in the rearview mirror exposes the second and third rows of seating. Power is never in short supply, be it from the torque-happy diesel in the GL350 BlueTEC, the twin-turbocharged V6 and V8 in the GL450 and GL550 respectively, or the Teutonic terror beneath the bonnet of the GL63 AMG. Standard 4Matic all-wheel drive is always active in helping maintain the best traction and can even be equipped with a 2-speed transfer case for light off-roading. When the asphalt turns serpentine, a “sport mode” will firm the steering feel for better response.
Favorite Features
BlueTEC DIESEL V6 ENGINE
Diesel’s acceptance is growing by leaps and bounds in the U.S., helped along by such wonderful engines as the 3.0-liter V6 found in the 2015 GL350 BlueTEC diesel. Although it has more torque than most V8s, the BlueTEC engine still manages a respectable 26 mph highway.
SURROUND VIEW SYSTEM
The GL’s Surround View system employs four cameras positioned at the vehicle’s front, back and sides. The combined images create a 360-degree birds-eye view around the GL, making parking easier and accidents less likely.
Vehicle Details
Interior
The 2015 GL-Class seats seven passengers in three rows with good legroom for all occupants. Cargo space behind the third row is somewhat limited, but folding the second and third rows down opens up the cargo capacity to a generous 93.8 cubic feet. Fit and finish of the interior is impeccable, with soft-touch surfaces and lots of well-done wood and metal trim. Standard equipment includes MB-Tex, which is very much like leather, with real leather an option. The seats themselves are terrific for long hauls, and outward vision is good except to the rear, so the blind-spot monitoring system is a wise choice.
Exterior
The rugged, somewhat boxy look of the 2015 GL-Class luxury SUV will not be mistaken for anything other than a Mercedes. Its purposeful stance has a definite presence, with a reasonable step-in height aided by a small side step rail and an easily accessible roof rack. Gracing the GL’s sides are artful creases and detailing, and the entire effect is one of luxury, style and confidence. Taller drivers and passengers will appreciate the rear liftgate’s high travel, allowing easy loading of large items while reducing the chance of bruising one’s forehead.
Notable Standard Equipment
Even the base 2015 Mercedes GL-Class is well-equipped. The GL350 has heated front seats, dual-zone climate control, sunroof, power tailgate, power-folding third-row seats, rearview camera and an audio system with a 6-disc CD/DVD changer. Bluetooth audio streaming is standard but, if you want to physically connect your iPod, that’s extra in the base model GL350 and GL450 and standard in the top-line GL550. The mbrace2 system lets you check on your vehicle, lock/unlock it and more from a smartphone or computer. Safety features include crosswind stabilization and systems that monitor for driver drowsiness or an impending collision.
Notable Optional Equipment
Extras for the GL-Class are in the form of packages or as stand-alone options. The package that includes a premium harman/kardon sound system and soft-close doors is nearly $6,000. Others packages, such as a heated wood-and-leather steering wheel, are relative bargains at just a few hundred dollars. Additional features include a night-vision assist system, blind-spot monitoring, navigation system and 3-zone climate control. For the few who will want to venture off the beaten track in this luxury SUV, the On/Off Road package has a 2-speed transfer case, 6-mode drive selector and added underbody protection.
Under the Hood
The GL350 uses a 3.0-liter V6 BlueTEC turbodiesel engine with 455 lb-ft of torque and an EPA highway fuel-economy rating of 26 mpg. The GL450 has a twin-turbo 3.0-liter V6 that can launch it to 60 mph in 6.6 seconds, while the GL550 employs a 4.6-liter twin-turbo V8 that can make the same sprint in a mere 5.5 seconds. The GL63 AMG has a hand-built 5.5-liter twin-turbo V8 that makes an enviable 550 horsepower. GL-Class models have 4Matic all-wheel drive standard, and all engine choices are connected to a smooth 7-speed automatic transmission.
