The 2018 Mercedes-Benz G-Class SUVs

For nearly four decades, the G-Class has continuously reinvented itself to conquer hurdles in all sorts of climates. The 2018 Mercedes-Benz G-Class melds its iconic, military-grade design with ultra-modern luxury. Capable of astounding feats, such as towing nearly 8,000 pounds, or reaching 60 mph from a standstill in as little as 5.2 seconds, the G-Class SUV is built to achieve. To learn more about the new G-Class SUV and its outstanding capabilities, check out Mercedes-Benz of Ontario’s overview below!


The G-Class SUV is conditioned for the great outdoors with a 7-speed automatic transmission, steering wheel-mounted shift paddles, permanent all-wheel drive, and a 2-speed transfer case for a wider span of gear ratios. Using over 8 inches of ground clearance to its advantage, the G-Class adapts its suspension, coil springs, and gas-pressurized shocks to any driving surface. In fact, this SUV can climb an 80% grade and master a 54% lateral slope like the born performer it is. To give you a punch of power on Rancho Cucamonga terrain, it also includes:

  • Horsepower ranging from 416 to 621
  • ECO-START®/Stop technology
  • Three lockable differentials
  • Dual sidepipe exhausts
  • 7-speed AMG® SPEEDSHIFT® PLUS transmission (AMG® only)
  • AMG® high-performance braking system (AMG® only)

A Luxurious Interior for Five

Whether you’re running daily errands around Chino and Fontana or tackling off-road adventures, the G-Class is crafted to keep you comfortable and content. The seats inside the G 550 are fitted with Nappa® leather, while the AMG® G 63 and AMG® G 65 get designo® Nappa® leather upholstery. In chilly regions, the electrically heated windshield prevents fog and frost buildup, while dual-zone climate control lets you and your front passenger set your own temperatures. During road trips and vacations, the split-folding rear seats can be adjusted slightly to make room for long objects or folded forward for a full 79.5 cubic feet of storage space.

Inside every 2018 G-Class, you’ll also find these must-have convenience features:

  • Power, multi-contoured front seats with a heating/ventilation function
  • Front-seat memory settings
  • Heated rear seats
  • 5-year mbrace® Connect Package
  • Heated and powered side mirrors with power fold-in
  • Auto-dimming rearview and driver-side mirrors
  • Interior ambient lighting
  • HomeLink™ garage door opener

Overflowing with the Latest Technologies

Every aspect of the G-Class is driven by intelligent technology. With the help of the COMAND® system display and central controller, placing hands-free calls, streaming audio, and searching for HD Radio™ stations is quick, easy, and enjoyable. Meanwhile, the standard COMAND® hard-drive navigation system reaffirms the G-Class SUV’s aptitude for adventure. The COMAND® system makes finding everything from a gas station to a landmark a cinch, and you can even store maps for later use. The following technologies are also part of your G-Class interior:

  • Voice control with a learning feature
  • Steering wheel-mounted controls
  • Free navigation map updates for three years
  • 12-speaker harman/kardon® Logic 7®* sound system
  • In-dash DVD/CD player and SD card reader
  • SiriusXM® Radio with a 6-month All-Access trial
  • Apple CarPlay® and Android Auto™

Be Prepared for Every Journey

From its 19- to 22-inch all-season tires, to its adaptive braking technology, to its efficient Bi-Xenon headlamps, the 2018 Mercedes-Benz G-Class conveys full-scale protection. In addition to a rearview camera, Trailer Stability Assist, Night Security Illumination, and rain-sensing wipers, this rugged family of SUVs also includes these standard driver assists:

  • Blind Spot Assist: This system displays a bright red icon in the side mirror if a vehicle is detected in your blind zone and emits a warning tone if you’re about to switch lanes while a vehicle is traveling alongside you.
  • Distance Pilot DISTRONIC®: As an adaptive cruise control system, Distance Pilot DISTRONIC® uses radar technology to adjust your speed to the flow of traffic and can even brake if a straight-ahead vehicle begins to slow.
  • Parking Assist PARKTRONIC®: Front and rear ultrasonic sensors assist you with low-speed maneuvers by audibly and visually warning you of nearby objects.
