One of the rarest and most luxurious variants of the W463 G-Class was the Maybach G650 Landaulet. Released under the Mercedes-Maybach brand, these ultra-luxury landaulet convertible SUVs were built on the extended wheelbase platform, and featured much of the suspension and running gear from the G500 4x4²/G550 4x4². Power comes from Mercedes' M279 E60 AL engine, which is a 6.0L twin-turbo V12 sourced from the G65 AMG. This powerplant delivers a mighty 621hp and 738 lb ft of torque that is sent to all four wheels via a 7 speed automatic transmission. A limited production variant, just 99 examples of the Maybach G650 Landaulet were built.
