The verdict

What's good

  • Iconic, head-turning boxy shape
  • Seriously capable off-road
  • Booming V8 with side-exit exhaust
  • Hand-built, jewel-like interior

What's not

  • Tippy, trucklike on twisty roads
  • Wind noise from the upright shape
  • Climbing in takes real effort
  • Loaded versions get eye-watering

The engine

M177 / M178

4.0L Twin-Turbo V8

AMG's hand-built 4.0-liter 'hot-vee' twin-turbo V8 is the soul of modern Affalterbach — thunderous, hard-hitting, and endlessly characterful, from the GT sports car to the G63 and 63-badged super-saloons.

Each engine is assembled start-to-finish by a single technician under AMG's 'One Man, One Engine' philosophy, the builder's name fixed to the cam cover on a signature plaque.
