The 2025 G63 is powered by a 4.0-liter twin-turbo V8 engine producing about 577 horsepower, paired with a 9-speed automatic transmission and full-time 4MATIC all-wheel drive. 
It delivers extreme performance for its size, accelerating from 0–100 km/h in about 3.7 seconds, while still maintaining legendary off-road capability with three locking differentials.
