2003 Mercedes-Benz G-Class Full Review
Date Published: 2/20/08
2003 Mercedes-Benz G-Class Review
This 5-passenger, body-on-frame 4-dr wagon was designed by Mercedes-Benz for the German army in the 1970s and recently adapted for the U.S. as a luxury SUV. "G" denotes the German term Galaendewagen--cross-country vehicle--and a tall, relatively narrow build reveals an all-terrain orientation. Two G-Class models are offered. The G500 has a 292-hp 5.0-liter V8. The G55 AMG from Mercedes' performance division has a 349-hp 5.4-liter V8. Both have a 5-speed automatic transmission, antiskid/traction control, antilock 4-wheel disc brakes with brake assist, and all-wheel drive with low-range gearing. Designed for severe off-road use, the AWD system allows on-the-fly low-range engagement up to 15 mph, and includes locking front, center, and rear differentials. Side and curtain airbags are unavailable. Both models come with 18-inch alloy wheels, sunroof, wood/leather interior trim, heated front and rear seats, and Mercedes' assistance and navigation systems. The G55 adds wider tires, side-exit exhaust, fender flares, front brush bar, rear chrome load steps, unique gauges, and uprated leather trim.
Competition
Luxury SUVs vary in size and type, including former members of both the Full-size and Midsize SUV classes, along with a few all-new models. All offer higher standards of workmanship, comfort, refinement, and pricing than other SUVs.

Our Best Buys are Acura MDX and Toyota Land Cruiser. Both are extremely capable on-road and offer roomy interiors that feature quality workmanship and materials. MDX gets slightly better fuel economy and is more reasonably priced. Land Cruiser offers a V8 engine, rugged body-on-frame chassis, and true off-road ability.

Though rugged and trucky, the Recommended Mercedes-Benz M-Class is spacious, offers a variety of model and engine choices, and numerous safety features. If you don't venture too far off-road, take a look at the car-based Lexus RX 300. Recommended based on price, refinement, and luxury appointments.
News
Sources are divided on what's next for G-Class. One report says the current 30-year-old soldier will fade away once Mercedes introduces a new-generation M-Class SUV, now expected for 2005-06. Another says the new M will be the basis for a clean-sheet G-Wagen built alongside it at Mercedes' Alabama plant. We think the latter scenario more likely. The G-Wagen doesn't draw many sales--under 2400 in the first nine months of 2002 vs. near 29,500 for M-Class--but each one yields a big profit, and Mercedes could likely do a cost-effective new-M spinoff that would be no less lucrative. Indeed, we hear that's already in the works, referred to in-house as the "MLG-Class."

Consumer Guide® Road Test Ratings
Acceleration

G500 Class Average
6 4.4

Test G500 clocked a respectable 7.9 sec 0-60 mph, helped by smooth, quick-shifting transmission. Midrange pickup is adequate, reflecting hefty weight and poor aerodynamics. Haven't yet tested G55, for which Mercedes claims 7.2 sec 0-60.
Fuel Economy

G500 Class Average
2 1.9

Both Gs require premium fuel--and lots of it. Test G500s averaged 13.0 mpg in mixed city/highway use, 12.8 including gas-eating performance tests. G55 likely thirstier still.
Ride Quality

G500 Class Average
3 5.4

Surprisingly stable, given firm, off-road-oriented suspension. Some chop due to short wheelbase, but never punishing. Still, most every other big SUV furnishes superior comfort.
Steering/Handling/Braking

G500 Class Average
3 3.3

Again, no match for more-modern rivals, but not as bad as tall, narrow build might suggest. Still, fast turns trigger tippy cornering feel, and most crosswinds cause highway wander. Steering very firm, and wheel is slow to return to center after turns. Brakes deliver sure, reasonably short simulated panic stops with little nosedive.
Quietness

G500 Class Average
3 5.2

Wind, tire noise rise markedly over 45 mph. Much full-throttle engine roar.
Controls

G500 Class Average
3 5

Clear gauge cluster. Complex Mercedes COMAND video system governs navigation/audio/cell phone. Most other switches are handy and mostly self-explanatory except for low-mounted, undersized climate controls. Weak dashboard night lighting. Old-fashioned, square-cut interior shapes, but materials are high quality, include wood trim. Creaks, groans over rail tracks at odds with otherwise-solid bearing.
Room/Comfort/Driver Seating (front)

G500 Class Average
5 7.4

Head room beyond generous, but cabin feels narrow in this 30-year-old design. Seats needlessly hard to some testers. Smallish footwells and lofty step-in complicate entry/exit; standard side steps help little. Drivers can easily see both front fenders, but elevated stance, headrest clutter, and dark-tint glass block much vision astern and over-the-shoulder.
Room/Comfort (rear)

G500 Class Average
5 6.4

Hard, flat bench seat high off floor, so head room only very good. But that also means steep step-in. And only fair leg room unless front seats well forward.
Cargo Room

G500 Class Average
8 6.9

Split 70/30 rear bench double-folds for cargo, but stiff latches on test G500s required undue muscle. Rear wheel arches steal some cargo space, but there's plenty of volume for big, tall boxes. Side-opening cargo door is clumsy--partly because it carries heavy, bulky outside spare tire. Small-items storage nothing special.
Value within Class

G500 Class Average
2 3.4

The G-Class achieved some celebrity cachet as a private import, one reason Mercedes began offering it through its own dealers during 2002. But this old soldier suffers too many lapses for what it costs. Other luxury SUVs--including Mercedes' own M-Class--furnish far better everyday comfort, refinement, and performance, usually for far less money.

Pricing Key: Retail prices listed with each report are set by the vehicle's manufacturer. These figures appear on each car's federally mandated window sticker. Most price lists also include dealer-invoice prices. Dealer-invoice prices are what the dealer pays the manufacturer for the car and its factory-installed options. The destination charge is not included in the suggested-retail or dealer-invoice price and must be added to the cost of the vehicle. Car companies change prices frequently throughout the year. If the prices published do not match those on the vehicle's window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

NHTSA Crash-Test Results
Test Mercedes-Benz G-Class 4-door wagon
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.
