It takes an old hand like Mercedes-Benz to show relative upstarts like Land Rover how to build a proper open-top off-roader. Set to make its debut at the 2017 Geneva Motor Show next month is the Mercedes-Maybach G 650 Landaulet, which makes the Range Rover Evoque Convertible look like a Power Wheels.

That’s because the G 650 is a behemoth of a vehicle, measuring 5,345 mm long and 2,235 mm tall, with a wheelbase of 3,428 mm – making it 659 mm longer and 302 mm taller than the standard G-Class. The length between the front and rear axles has also been stretched by 578 mm.

Speaking about the axles, the G 650, like the G 63 AMG 6×6 and the G 500 4×4², features portal axles – with reduction gears at each corner linking the axles to the wheels – to increase ground clearance to a massive 450 mm. The car also features three fully-locking differentials and a low-range gearbox (just like any other G-Class), plus 22-inch alloy wheels (complete with “Landaulet” script) shod with massive 325/55R22 tyres.

Under the bonnet, the powertrain is lifted straight from the AMG G 65, so it’s a 6.0 litre twin-turbocharged V12 that produces 630 hp and a whopping 1,000 Nm of torque. All that is sent to all four wheels via a seven-speed AMG Speedshift Plus 7G-Tronic automatic transmission.

But this impressive engineering pales in comparison to the level of opulence found behind the rear seats, which bask in the sunlight when the soft top (which only covers the rear portion, so it’s not technically a full convertible) is retracted. The significantly longer wheelbase allows the G 650 to be fitted with the active multi-contour rear seats of an S-Class, complete with their accompanying calf rests.

These seats feature brings forth all kinds of features, such a power adjustment, inflatable air chambers for improved comfort and lateral support and an Energizing massage function that is capable of providing a hot-stone massage complete with heat. There’s also a large centre business console with thermal cupholders, plus two leather-lined tables to provide a comfortable writing surface.

Ahead of the rear passengers sit twin 10-inch high-resolution displays that form the Individual Entertainment System, along with a centre console – styled to look like the one in the front – and twin gloveboxes. And just in case you need to keep yourself away from the riffraff (i.e. the driver and front passenger), there’s always the power-retractable glass partition to shield yourself.

Buyers can choose between four two-tone designo upholstery options (with diamond stitching), three matching soft top colours and four designo paint finishes. Differentiating the G 650 from other G-Class models on the outside are a chrome double-louvre grille, “V12 Biturbo” badging, huge carbon fibre wheel arch flares to cover the enormous wheels, front and rear underride guards and power-retractable side steps.

Built at the Magna Steyr plant in Graz, Austria alongside other G-Class models, the Mercedes-Maybach G 650 Landaulet will be limited to just 99 units worldwide, and will go on sale during the Geneva show, with deliveries beginning in the autumn.
