2025 Mercedes-Benz G 450 d W463 Australian Version
By Lorenzo Bianchi September 3, 2025
Powered by a 3.0-litre inline-six diesel with 48V mild-hybrid assist, the G 450 d produces 270 kW and 750 Nm.
Off-road kit includes 241 mm clearance, 700 mm wading depth, and 35° side-slope ability with an Offroad Cockpit feature.
Priced from AU$214,900, it sits below the AMG G 63 and alongside the electric G 580 EQ in the Australian lineup.
Powertrain and Driving Character
The G 450 d uses a 3.0-litre inline-six turbo diesel paired with Mercedes’ 48-volt mild-hybrid system. The numbers are straightforward: 270 kW, 750 Nm, and 0–100 km/h in 5.8 seconds. Top speed is limited to 210 km/h, which for a boxy SUV weighing over two and a half tonnes is no small feat.
The mild-hybrid system provides smoother low-end response and helps bring fuel consumption down. Official figures point to between 8.7 and 10.0 L/100 km depending on conditions. It’s not a small number, but for a G-Wagen with this level of torque, it’s a meaningful step forward.
Off-Road Numbers That Matter
Mercedes hasn’t softened the G 450 d for suburban duties. Ground clearance is 241 mm, approach and departure angles remain serious, and the SUV can wade through 700 mm of water. It’ll tackle side slopes of 35° without drama.
For drivers who want more data while crawling over obstacles, the optional Offroad Cockpit puts slope angles, drivetrain status, and diff locks on the central display. It’s useful tech, though the mechanical setup—ladder-frame chassis, low-range gearing, locking differentials—is what makes the G a G.
Exterior and Cabin
Visually, the G 450 d is still the G-Class: upright body, exposed hinges, spare wheel on the back. Buyers can choose extras such as 18-inch black alloy wheels and MULTIBEAM LED headlights, but the overall look hasn’t been tampered with.
Inside, the specification leans more toward luxury than utility. Standard kit includes walnut wood trim, a Burmester 3D audio system, sunroof, and dual 12.3-inch displays running the latest MBUX interface. There’s smartphone integration, augmented-reality navigation, and full driver-assistance tech including DISTRONIC adaptive cruise and Active Steering Assist. Mercedes also includes GUARD 360° vehicle protection for security.
Pricing and Positioning
The G 450 d launches in Australia at AU$214,900 before on-road costs. That figure places it below the AMG G 63, and in line with the new electric G 580 EQ. Mercedes is offering several packages to tailor the SUV:
