What are the differences between the G500 and G63?

[IanLee]

The differences between the G500 and G63 are as follows: Difference 1: Engine The Mercedes-Benz G63 can be considered the successor to the G55. Apart from having a more powerful engine, although both the G500 and G63 are equipped with a 4.0T twin-turbocharged V8 engine, their power outputs are completely different. The G63 can deliver up to 585 horsepower, while the G500 only has 421 horsepower. In terms of peak torque, the G63 also exceeds the G500 by 240 Nm. Difference 2: Design Although both models are produced by Mercedes-Benz, the G500 retains the factory design, while the G63 has been modified. As Mercedes-Benz's dedicated tuning division, AMG has equipped the G63 with a full body kit and made various modifications to the exhaust, wheels, and brakes, making it significantly more expensive than the G500. After the modifications, the large front bumper looks particularly imposing, and the overall appearance is very stylish. Difference 3: Performance In terms of off-road capabilities, the entire Mercedes-Benz G-Class lineup is equipped with a full-time four-wheel-drive system and features three differential locks, so it remains a professional off-road vehicle. It can wade through water depths exceeding 600mm and has a side tilt angle of 28°. However, because hardcore SUVs generally don't perform very well on highways, the new G-Class has improved its on-road performance. Another difference between the G63 and G500 lies here—the G63 has more advanced configurations, offering a stronger sense of technology and driving comfort compared to the G500.

During the test drive, it was obvious that these two cars have different positioning. The 4.0T V8 engine in the G500 is already powerful, but the G63 is tuned more aggressively, featuring an AMG-exclusive sport exhaust system—the roar when flooring the accelerator is on a completely different level. In terms of chassis, the G63 comes standard with adaptive suspension, providing much stronger cornering support, while the regular G500 feels noticeably bumpier over speed bumps. Externally, the G63’s wide fender flares, AMG front bumper, and red brake calipers give it a more aggressive look, and the interior racing bucket seats and AMG steering wheel badge are exclusive to the performance version. However, the fuel consumption is staggering—driving the G63 daily, you can literally watch the fuel gauge drop.

Having run a repair shop for twenty years and worked on numerous G-Class models, the most noticeable difference lies in the engine bay layout: the G63 features a reinforced cooling system, with redesigned turbochargers and intake piping. In terms of the chassis, the G63 has additional front anti-roll bars and uses aluminum rear suspension arms for weight reduction. While both models share a 9-speed automatic transmission, the AMG version adopts a more aggressive shift logic, deliberately maintaining higher RPMs during downshifts with throttle blips. Brake-wise, the G500 comes with 380mm front discs paired with four-piston calipers, whereas the G63 upgrades to 420mm drilled discs and six-piston calipers. Maintenance costs differ significantly—replacing just the high-performance brake pads on a G63 can cost as much as the entire brake system of the standard version.

As an off-road enthusiast, I pay more attention to mechanical performance. The G500 is already very powerful, equipped with three differential locks and low-range four-wheel drive. However, the G63's excessive power actually limits its off-road capability, as its high-revving turbo tends to overheat during desert hill climbs. There's a noticeable difference in body width—the G63's wider track makes it prone to scraping fenders in narrow jungle trails, while the standard G500 is more agile. There's also a difference in modification potential: the G500 can easily gain 80 horsepower with a simple ECU tune, whereas the G63 is already near its limit, requiring expensive forged pistons for further upgrades. If you frequently venture into remote areas, the G500 with its longer range is actually more reliable.

The difference in interior impact between the two cars is most striking. Upon entering the G63, one is immediately embraced by AMG-exclusive bucket sports seats, with Nappa leather upholstery featuring diamond-pattern quilting. The center console adds a Race driving mode knob, and the instrument cluster displays turbo pressure values. The G500 prioritizes comfort more, with standard seat ventilation and massage functions. In terms of details, the AMG version features stainless steel pedals with rubber studs, and the perforated positions on the steering wheel better suit track driving grips. Both cars come equipped with the top-tier Burmester sound system, but the G63 loses some high-frequency details due to exhaust noise interference. The price difference in luxury features is reasonable, and the choice depends on personal needs.

Budget-conscious owners are advised to calculate hidden costs: the G63 costs over a million more than the G500, with 15-20% higher fuel consumption, an additional 2,800 in vehicle tax based on displacement, and about a 30% increase in insurance premiums. The G63 does have slightly better resale value, especially limited editions which hold their value more firmly. Maintenance intervals are every 10,000 km for both, but AMG-specific oil costs four times more than standard certified oil. The parts-to-labor ratio exceeds 600% for both, though the G63 offers far more aftermarket parts than the standard version. If it's purely for prestige, aftermarket kits can be added later, but true performance enthusiasts must go for the factory AMG.
