The car

About the Mercedes-Benz G63 AMG (W463A)

For 2019 the G63 was extensively re-engineered. The ladder frame stays, but for the first time the front axle has independent double-wishbone suspension, mounted directly to the frame; the rear keeps a rigid axle, and Mercedes-AMG says torsional rigidity of the frame, body and mounts rose by about 55 percent.

A hand-built 4.0-liter twin-turbo V8 with cylinder deactivation replaced the 5.5-liter, paired with the AMG SPEEDSHIFT TCT 9G automatic. All-wheel drive became rear-biased at 40:60, with three differential locks and a low-range ratio of 2.93:1, and the cabin gained a widescreen cockpit.

Mercedes-Benz estimates 0–60 mph in 4.4 seconds for 2019 and quotes an electronically limited 137 mph, or 149 mph with the AMG Driver’s Package.

Stage 1 is calibrated for the car as it left the factory and takes it from 577 hp and 627 lb-ft to 760 hp and 735 lb-ft on pump-grade fuel. Stage 2 is calibrated for supporting bolt-on modifications and high-octane fuel, for 800 hp and 750 lb-ft. The gearbox has its own controller and torque limits, so the optional TCU tune raises them to match, with sharper shifts and stronger clutch clamping.

FAQ

G63 AMG (W463A) tuning questions

More answers in our FAQ

Which years of the G63 AMG (W463A) does this tune fit?

Our online catalog lists Stage 1 and Stage 2 tunes for 2019–2024 Mercedes-Benz G63 AMG (W463A) models. Choose your year at the top of the page; the figures and prices are the same for every year.

Is the 2025 G63 covered here?

No. From the 2025 model year the G63 adds a hybrid-assist system to its V8, a change to the powertrain, and our catalog lists this generation for 2019–2024. Contact us about a 2025 or newer G63 before ordering.

How does the G63 differ from the G550 of the same years?

Both use the same body, ladder frame, independent front suspension and three differential locks. The G550 has its own 4.0-liter twin-turbo V8 with the 9G-TRONIC automatic and a 130 mph limiter, while the G63 gets AMG’s hand-built engine, the AMG SPEEDSHIFT TCT 9G and AMG-developed suspension. The G550 (W463A) has its own page.

What is the difference between Stage 1 and Stage 2 on the G63 AMG (W463A)?

Stage 1 is calibrated for the car as it left the factory and runs on pump-grade fuel. Stage 2 pairs the calibration with supporting bolt-on modifications such as downpipes and runs on high-octane fuel. On a 2024 car, Stage 1 takes it from 577 hp to 760 hp. Stage 2 takes it to 800 hp.

Do I need a TCU tune for the G63 AMG (W463A)?

A TCU tune is available as an add-on ($2,399). It raises the transmission’s torque limits and sharpens the shifts so the gearbox can handle the extra power. Ship your TCU in the same box as your ECU.
