How does the Mercedes-Benz G-Class compare to the Land Rover Defender and Range Rover?
For buyers seeking a five-seat luxury SUV with selectable differential locks and low-range gearing, we recommend starting with the Mercedes-Benz G 450 d. Its documented off-road hardware and recognisable G-Class design make it a focused choice for that brief. If seven seats are essential, the G 450 d does not meet that requirement; suitably configured Defender 110 and Range Rover models provide alternatives examined below.
This comparison uses the diesel G 450 d as the G-Class reference, the Defender 110 body style and the full-size Range Rover. It does not treat the electric G-Class, AMG G 63, Defender OCTA, Range Rover Sport and standard vehicles as interchangeable. Those choices need their own specifications and quotes.
The differences that should decide your shortlist
| Question | Mercedes-Benz G 450 d | Defender 110 | Full-size Range Rover |
|---|---|---|---|
| How many people? | Five seats | Up to seven, depending on configuration | A Long Wheelbase seven-seat version is available |
| What defines its off-road proposition? | Three selectable 100% differential locks; LOW RANGE | Off-road systems and capability vary by derivative and suspension | A blend of off-road systems and passenger-comfort features; specify the exact model |
| What should you check first? | Whether the five-seat layout and vehicle size meet your everyday needs | Which seats and suspension are actually fitted | Standard or Long Wheelbase, seating layout, options and physical parking fit |

What the G-Class does differently
Mercedes' Australian G-Class page identifies the G 450 d as a five-seat, six-cylinder diesel with a nine-speed automatic. It lists the engine rating and mild-hybrid assistance separately; those figures should not simply be added and compared with another manufacturer's combined-output number.
The more distinctive difference is the hardware and how it is used. Mercedes describes three individually selectable differential locks and a low-range function. For buyers who specifically want this combination for controlled low-speed off-road driving, these are the functional reasons behind our G-Class recommendation. Compare the exact competing derivative's equipment rather than inferring capability from its range name. G-Class technical information and off-road equipment
For a buyer whose five-seat requirement fits the G 450 d, the appeal is a clearly defined off-road package within a distinctive Mercedes model. Its seating, equipment and physical size can be assessed against your own routine before considering a different configuration.
Check whether the Defender's extra seating changes your requirements
The Defender 110 offers configurations with up to seven seats. That can settle the comparison immediately if six or seven people regularly travel together: the five-seat G 450 d is not a substitute for a vehicle with approved extra seats.
Land Rover advertises a maximum 900 mm wading depth on the Defender 110 page, but its range combines figures from different derivatives. Read the configuration-specific footnotes rather than applying every headline maximum to one vehicle. The same caution applies to towing: the page specifies a 3,000 kg maximum for its plug-in-hybrid example. That figure is not a blanket rating for the range. Defender capabilities and qualifications
If you need a workhorse for family trips, compare seat access and remaining luggage space with everyone aboard. A maximum cargo figure measured behind the first row is not the space left when the third row is occupied.
Compare the Range Rover's wheelbase and passenger configuration
Range Rover's Long Wheelbase seven-seat layout is a different proposition again. Its Australian material focuses on passenger accommodation, cabin materials and comfort features, with equipment depending on specification.
The manufacturer publishes a 10.95 m turning circle for Standard Wheelbase and 11.54 m for Long Wheelbase. That makes wheelbase a practical purchase decision, not just a styling choice. Turning circle still does not tell you whether the vehicle fits through your garage entrance or whether occupants can open their doors. Range Rover dimensions and equipment notes
A longer vehicle can offer the passenger arrangement you want while creating a parking trade-off. Test both needs before paying for a configuration you will find awkward every day.
Compare cargo and ownership costs fairly
Land Rover labels certain Defender cargo measurements as wet volume, simulating the space filled with liquid. Other specifications may use block-based or differently bounded measurements. Do not rank two SUVs by litres until you have checked the measurement method, seating position and whether underfloor space is included. Defender cargo measurement note
Obtain driveaway quotes for named variants in the same state. Then compare insurance quotes, the tyres actually fitted, scheduled-servicing terms and the towing setup you require. Use those actual costs alongside the hardware and seating requirements that shaped your shortlist.
Our recommendation for a five-seat luxury off-roader
Start with the G 450 d when its five-seat layout, selectable differential locks and low-range gearing match the vehicle you want. Those documented features provide a clear basis for choosing a Mercedes demonstration rather than treating the three ranges as interchangeable.
If you need more seats, the Defender 110 or a suitable Range Rover configuration can change the shortlist. Wheelbase, luggage measurement and variant-specific towing limits also remain important differences. For the five-seat Mercedes brief, explore the G-Class and ask the retailer to demonstrate the selected vehicle with your passengers and usual load.
