For enhanced safety, the front and rear seat shoulder belts of the Mercedes G-Class have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Tahoe doesn’t offer pretensioners for its second-row seat belts.

The G-Class’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tahoe doesn’t offer pre-crash pretensioners.

The Mercedes G-Class has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Tahoe doesn’t offer knee airbags.

The G-Class has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tahoe doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G-Class. But it costs extra on the Tahoe.

The G-Class’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Tahoe doesn’t offer a driver alert monitor.

Both the G-Class and the Tahoe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The G-Class comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Tahoe’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The G-Class’ corrosion warranty is unlimited miles longer than the Tahoe’s (unlimited vs. 100,000 miles).

Engine

The G-Class has more powerful engines than the Tahoe:

	Horsepower	Torque
G 550 3.0 turbo 6-cylinder hybrid	443 HP	413 lbs.-ft.
AMG G 63 4.0 turbo V8 hybrid	577 HP	627 lbs.-ft.
G 580 electric motors	579 HP	859 lbs.-ft.
Tahoe 5.3 V8	355 HP	383 lbs.-ft.
Tahoe 6.2 V8	420 HP	460 lbs.-ft.

As tested in Car and Driver the AMG G 63 4.0 turbo V8 is faster than the Chevrolet Tahoe 5.3 V8:

	G-Class	Tahoe
Zero to 60 MPH	3.9 sec	7.5 sec
Zero to 100 MPH	10 sec	20.5 sec
5 to 60 MPH Rolling Start	5.1 sec	8.4 sec
Quarter Mile	12.5 sec	15.8 sec
Speed in 1/4 Mile	110 MPH	89 MPH
Top Speed	149 MPH	115 MPH

Fuel Economy and Range

On the EPA test cycle the G-Class running on electricity gets better mileage than the Tahoe:

			MPGe
G-Class
	AWD	580 Electric Motors	68 city/53 hwy
Tahoe
			MPG
	RWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/20 hwy
	AWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/18 hwy

On the EPA test cycle the G-Class running its gasoline engine gets better mileage than the Tahoe:

			MPG
G-Class
	AWD	550 4.0 turbo V8	17 city/19 hwy
Tahoe
	RWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/20 hwy
	AWD	5.3 OHV V8	15 city/20 hwy
		6.2 OHV V8	14 city/18 hwy

The G 580 can travel with zero emissions for 239 miles. The Tahoe can’t move without running its internal combustion engine.

Regenerative brakes improve the G-Class’ fuel efficiency by converting inertia back into energy instead of wasting it. The Tahoe doesn’t offer a regenerative braking system.

The G-Class has 2.4 gallons more fuel capacity than the Tahoe (26.4 vs. 24 gallons), for longer range between fill-ups.

The G-Class has a standard locking fuel door and a locking charge port on the 580 which lock and unlock with the power locks. The Tahoe doesn’t offer a locking fuel filler door. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank and a locking charge port prevents tampering and damage.

Transmission

The G-Class AMG 63’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Tahoe doesn’t offer launch control.

Brakes and Stopping

For better stopping power the G-Class’ standard brake rotors are larger than those on the Tahoe:

	G-Class	Tahoe
Front Rotors	13.9 inches	13.5 inches

The G-Class stops much shorter than the Tahoe:

	G-Class	Tahoe
70 to 0 MPH	161 feet	184 feet	Car and Driver
60 to 0 MPH	123 feet	134 feet	Motor Trend

Tires and Wheels

For better traction, the G-Class’ optional tires are larger than the largest tires available on the Tahoe (295/40R22 vs. 285/40R24).

The G-Class’ standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Tahoe’s standard 65 series tires.

Suspension and Handling

The G-Class has standard front and rear stabilizer bars, which help keep the G-Class flat and controlled during cornering. The Tahoe’s suspension doesn’t offer a rear stabilizer bar.

The G-Class AMG 63 offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Tahoe doesn’t offer an active sway bar system.

The AMG G 63 offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Chevrolet doesn’t offer an active suspension on the Tahoe.

The G-Class has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Tahoe doesn’t offer variable-assist power steering.

The G 580 handles at .80 G’s, while the Tahoe Z71 4x4 pulls only .63 G’s of cornering force in a Car and Driver skidpad test.

The AMG G 63 executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the Tahoe LT 4x4 (28.2 seconds @ .64 average G’s vs. 29.4 seconds @ .54 average G’s).

For greater off-road capability the G-Class has a 1.5 inches greater minimum ground clearance than the Tahoe (9.5 vs. 8 inches), allowing the G-Class to travel over rougher terrain without being stopped or damaged.

Chassis

The G 550 is 2 feet, 5.3 inches shorter than the Tahoe, making the G-Class easier to handle, maneuver and park in tight spaces.

Cargo Capacity

The G-Class has a much larger cargo volume than the Tahoe with its rear seat up (34.8 vs. 25.5 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the G-Class easier. The G-Class’ cargo hatch lift-over height is 29.3 inches, while the Tahoe’s liftover is 37 inches.

Ergonomics

Unlike the driver-only memory system in the Tahoe LT/RST/Z71/Premier/High Country, the G-Class has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The G-Class’ front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Tahoe’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the G-Class the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Tahoe can only close the windows from inside the vehicle, with the ignition on.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The G-Class has standard headlight washers to keep headlight output high. The Tahoe doesn’t offer headlight washers.

To help drivers see further while navigating curves, the G-Class has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Tahoe doesn’t offer cornering lights.

The Mercedes G-Class has power folding mirrors that offer unparalleled convenience while maneuvering in tight places or parked. With the mirrors folded it’s easier to walk past and help prevent parking damage. The mirrors can be quickly unfolded when the driver is ready to leave. Power folding mirrors costs extra on the Tahoe and aren't offered on the LS.

The G-Class has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Tahoe.

The G-Class offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Tahoe.

The Mercedes G-Class has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the rear view mirror. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Chevrolet charges extra for Homelink® on the Tahoe.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Mercedes G-Class has a standard wireless phone charging system (Qi) in the center console. Only the Tahoe LT/RST/Z71/Premier/High Country offers wireless charging.
