The G Class was initially introduced as a rugged and tough off-road military vehicle in the 1970s. Later, it was introduced as a civilian model and with time it was driven more on paved roads than off. In recent times, it became a status symbol especially for celebrities driving up and down Rodeo Drive.

Mercedes has been producing cars for a very long period of time and over the years, they have mastered the recipe. The G 63 has not always been the pinnacle of luxury. Everything a normal human being can imagine has changed over these five decades. Luxury and style were the only things that mattered in the 1970s when the first G came out but that is not the case anymore.

Overall Rating


The 2020 Mercedes Benz G 63 has a base MSRP of $152,000 and with options, it can easily shoot up to $165,000. For that money, a rational person would expect it to have everything in the world and this monster on four wheels delivers on that expectation to some extent. The G Wagon is not just about luxury and comfort, it is a very capable off-roader.

The “G-Rex” stands next to the Lamborghini Urus, Bentley Bentayga and the Range Rover SV Autobiography. All of these vehicles are very capable in their own sense. Today, when this segment is already filled up to the brim, let’s find out which one to go for.

2020 Mercedes-Benz AMG G 63 Engine and Performance

7.5/10

The AMG G63 is powered by a 4-liter V8 which is assisted by a bi-turbo setup. This engine is capable of pumping out 577 horses. Even though the peak power comes in at a relatively high 6000 RPM, the engine feels peppy throughout the rev range as the peak torque of 627 lb-ft comes in at as low as 2,500 RPM.

2020 Mercedes-Benz AMG G 63 SUV Has a 4.0L, Bi-Turbo, V8 Engine 

The wide powerband means that the G is capable of doing city speeds as well as highway runs without issues. The 9-speed automatic transmission makes sure that you don’t feel any shifts. You might be cruising down the PCH in the 9th gear and the moment you step on the gas, the G will drop a “bunch” of gears and you’ll be pinned in your seat for good.

If you believe in “no replacement for displacement”, the Land Rover Range Rover SV Autobiography has the biggest engine in this bunch- a 5-liter Supercharged V8. This powertrain can push out a maximum of 557 horses and 516 lb-ft of torque. The Bentayga and the Urus share a similar powertrain with a 4-liter twin turbo V8 paired to an 8-speed automatic transmission. The Urus has 641 horses whereas the Bentayga does with 542 horses. This goes on to show us how biased the Urus is towards performance. Let’s be honest, none of these mean machines are short on power.

Acceleration

Acceleration figures shouldn’t really matter for a vehicle like the AMG G63. But it’s 2020 and yes, these figures matter. The 4-liter bi-turbo V8 motor manages to propel the G to 60 miles an hour from a standstill in 4.4 seconds. This AMG covers the quarter-mile in 12.6 seconds. The new 9-speed automatic transmission from Mercedes makes sure that the G doesn’t lose much time between gearshifts.

The Range Rover SV is capable of doing the 0-60 miles per hour sprint in 5.4 seconds and covers the standing quarter-mile in 13.1 seconds. The Urus and the Bentayga essentially have the same engine- a 4- liter twin-turbo. Having said that, both the engines have a different state of tune. The Urus does the 0-60 sprint in 3.6 seconds which is pretty impressive for an SUV. It does the quarter-mile in 11.4 seconds. Talking about the Bentayga, it manages the 0-60 sprint in 4.4 seconds. The quarter-mile timings of the Bentayga are not available yet.

The G63 is at par with the Bentayga with a 0-60 time of 4.4 seconds and a quarter-mile time of 12.6 seconds. So, if you plan to take on a supercar at the traffic light, the Urus is the best choice out of this bunch.

Braking

To compliment all the performance on offer and the weight the G63 carries, it needs to be equipped with good brakes. The G63 is equipped with 15.7-inch rotors in front and 14.6-inch ones in the back. The AMG Performance Brakes consist of red-painted 6 piston calipers in the front and single-piston units in the back. These brakes feel solid. Having said that, they might actually feel unpredictable to new drivers. These brakes manage to tame the 5842-pound “G-Rex” with confidence.

The Lamborghini Urus has the largest brakes in the bunch. Actually, the Lamborghini Urus has the largest brake rotors ever fitted to a production vehicle. The Bentley and the Range Rover are quite similar when it comes to brake sizes. The Bentayga has 15.8-inch units in the front and 15-inch rotors in the back. The Range Rover has 15-inch rotors in the front and 14.4-inch ones in the back.

Exact braking figures of the G63 and the Bentayga are not available. However, the Urus and the Range Rover performed pretty well in the 60-0 braking test. They managed to come to a complete halt from 60 miles per hour in 111 feet and 117 feet respectively.

2020 Mercedes-Benz AMG G 63 Fuel Economy

3.0/10

The G63’s 4-liter bi-turbo motor manages 13 miles per gallon in city driving. Drive it at highway speeds, the G would return 15 miles to the gallon. Not really impressive, is it? The combined fuel economy of the G63 is 14 miles per gallon.

When it comes to comparing these vehicles in terms of fuel economy, there is not a lot that can be said. All of these vehicles were not made with fuel efficiency in mind. The V8 Bentayga performs the best with 14/20/16 miles per gallon for city, highway, and combined respectively. The Range Rover comes in second with 14 miles per gallon for city usage, 19 mpg on the highways and 16 miles to the gallon combined. The Lamborghini Urus and the G63 are pretty similar in terms of fuel economy. Let’s just settle on the fact that these vehicles aren’t exactly fuel-efficient.

7.0/10

One of the biggest complaints with the previous generation G63 was the harsh ride quality. With the latest generation, Mercedes claims to have redesigned and taken care of most of the issues with the last generation. The new independent suspension setup makes the G more agile and comfortable.

The front seats offer a good amount of comfort but lack in terms of support. The seats also offer plenty of adjustment which makes finding an ideal driving position pretty easy. In terms of roominess, due to its boxy shape, it is pretty spacious. The G Wagon offers a ton of headroom, legroom and shoulder room.

As far as the back seats are concerned, they don’t offer plenty of support either but they are still comfortable. Having said that, just like the front seats the rear seats also offer plenty of room to the passengers. In terms of ride quality, the Mercedes AMG G63 is definitely a step up over the previous model but still, it has a long way to go.

When it comes to interior space, none of these vehicles fall short. All of them have plenty of space inside in order to accommodate everyone with comfort. The exact interior dimensions of the Urus are not available. Overall, the Range Rover SV Autobiography offers the highest interior room out of this bunch. In terms of comfort, the Range Rover offers the best value for money.

Infotainment System

Two 12.3-inch displays blend visually into a wide-screen cockpit beneath a shared glass cover. Drivers can choose between three different styles for the displays - Classic, Sport and Progressive. The standard audio system features seven loudspeakers. The Burmester surround sound system with 16 speakers and a 590-watt amplifier with Digital Sound Processing is available as optional equipment.

Standard features in the G-Class include a sunroof, tri-zone automatic climate control, and the COMAND infotainment system with a 12.3-inch display screen, touchpad controller, navigation, Bluetooth, two USB ports, three 115-volt household-style power outlets, a 15-speaker Burmester audio system, satellite radio, HD Radio, Apple CarPlay, and Android Auto. A Wi-Fi hot spot and a rear-seat entertainment system are available.

  • 3-inch high-resolution central display
  • 3-inch digital instrument cluster
  • No-charge online navigation map updates for 3 years
  • 3 years of Live Traffic service provided by TomTom
  • Burmester Surround Sound System

Cargo volume

When it comes to practicality in terms of cargo capacity, the G63 is in a league of its own. The G63 offers 38 cubic feet of cargo space with the second row in position. The rear seat can be folded in 60-40 configuration. This makes carrying longer items easy while carrying passengers. Once the rear seat has been folded the G63 can hold 79 cubes. What adds to the practicality of the trunk is the boxy shape of the vehicle. But, there is a downside- the ride height. The high ride of the G63 makes it pretty difficult to load heavy items into the trunk. In terms of interior storage, the G Wagon has improved a lot over the previous generation but it still has a long way to go.

6.0/10

The G Wagon has essentially looked the same throughout its life cycle- a boxy, slab-like shape with circular headlights and a 90-degree windshield. This style has become an icon over time and makes the G instantly recognizable. A lot of other manufacturers have tried to copy the styling of the G Wagon and have failed at doing so.

2020 Mercedes-AMG G63 SUV Three Quarter View

The legendary styling of the G makes it impossible to confuse it for any other vehicle on the road. You see those rounded headlights with circular DRLs in your rearview mirror and you just know that it is a G Wagon. In terms of exterior dimensions, the G is properly big with 5842 lbs of pure German metal built to last like a Soviet tank.

None of these vehicles are small when it comes to size. All of them give the “big SUV” look. These big dimensions prove to be useful for a ton of things. The extra ground clearance helps in clearing obstacles without any issue. The G Wagon has the highest amount of ground clearance and that makes it one of the most capable off-roaders in the world. The 9.5 inches of ground clearance on offer with the G63 is really impressive.

In terms of exact dimensions, all of these vehicles have a very similar footprint. The G is the highest, the Bentayga is the longest and the Urus has the longest wheelbase. Yes, these big dimensions make it slightly difficult to drive the vehicle around towns but drivers get used to it after a short while. The Lamborghini Urus and the Bentley Bentayga are also equipped with rear-wheel steering that makes it pretty east to maneuver around towns.

The mighty G 63 has not been crash-tested by the NHTSA or the IIHS. Having said that the Merc is filled to the brim with safety features and the fact that other Mercedes models such as the 2019 E Class sedan scored a perfect rating in both the tests give us an idea of how good and well-engineered a Benz is.

Mercedes AMG G63 vs Lamborghini Urus

Both the G and the Urus are very capable vehicles in their own sense. The G63 offers a combination of class, style, power, and off-road capabilities. On the other hand, the Urus just like any other Lamborghini offers a more childish approach.

2020 Lamborghini Urus

It offers brute power and extreme styling. In terms of interior tech and comfort, both the G and the Urus are somewhat at par with each other.

Mercedes AMG G63 vs Bentley Bentayga

Both the G and the Bentayga are somewhat similar. Both these vehicles offer top-notch comfort, tech, and safety. If you want better performance, the G Wagon is the one. If you want to flaunt what you drive, the Bentayga has more bling.

2020 Bentley Bentayga

One of the biggest things going for the G is its price. Instead of spending more on the Bentley, you can spec your G Wagon and make is more feature-rich and personalized.

Mercedes AMG G63 vs Land Rover Range Rover SV Autobiography.

The Range Rover is more of a style icon than a performer. It is used by the Royal family of England and that speaks volumes about the image of the vehicle. Being the SV Autobiography trim, it is already filled up to the brim with tech and features.

2020 Land Rover Range Rover SV Autobiography.

One big aspect it looses out on is reliability. In the recent past, Range Rover has established itself as one of the least reliable vehicles out there.

2020 Mercedes-Benz AMG G 63 Final Verdict

All four of these vehicles are a status symbol. They make a statement on your behalf even before you step out of it. The Urus with a funky front end makes an even bolder statement and to be quite honest, this might not be a thing for everyone’s taste. Having said that, the G63, the Range Rover and the Bentayga are more elegant, stately and graceful. Each one of these vehicles have major pros that work in their favor. If you want brute power, the Urus is the one to go for. If you want a big status symbol, go for the Bentley. If you want extreme off-road capabilities, go for the G63 and if you want to arrive like the Queen of England, go for the Land Rover Range Rover SV Autobiography.
