The legendary G-Wagen diesel is back, bringing torque-rich performance and mild-hybrid efficiency to Australian roads.

Mercedes-Benz Australia has officially expanded its iconic G-Class portfolio with the arrival of the all-new G 450 d. Returning to local showrooms to complement the high-performance Mercedes-AMG G 63 and the all-electric G 580 with EQ Technology, this diesel-powered variant answers strong customer demand for a traditional yet technologically advanced off-roader. Blending its signature utilitarian roots with modern luxury, the G 450 d arrives with the rugged "PROFESSIONAL Line" exterior as standard, signalling its readiness for both the high street and the bush.

Pricing

The G 450 d is positioned as the new entry point into the Australian G-Class range.

2026 Mercedes-Benz G 450 d: $214,900 (MRLP)

Note: The Manufacturer’s Recommended List Price (MRLP) includes GST and Luxury Car Tax (LCT) applicable to the base model but excludes all on-road costs such as registration fees, stamp duty, and compulsory third-party insurance.

Drivetrain and Efficiency

Under the bonnet, the G 450 d features a potent 3.0-litre inline six-cylinder diesel engine, now enhanced with 48-volt mild-hybrid technology.

The integrated starter-generator (ISG) and 48-volt electrical system improve efficiency and responsiveness, ensuring strong performance across all conditions. Power is sent to all four wheels via a permanent all-wheel-drive system, supported by three mechanical differential locks and a LOW RANGE off-road gear reduction—essential tools for navigating demanding terrain.

The G 450 d retains the unmistakably angular silhouette that has defined the G-Class since 1979. Built on a traditional ladder-frame chassis with a rigid rear axle and independent front suspension, it balances off-road durability with on-road refinement.
