A new report indicates Mercedes-Benz is planning an engine change for the G500 off-roader.

[update] Wolf-Dieter Kurz, Vice President Product Group SUVs and Sportscars at Mercedes-Benz told Autovisie the G500 is indeed getting the 4.0-liter V8 twin-turbo engine. The output has not been finalized but he said it should be close to 422 PS and will be available towards the end of the year.

A new report indicates Mercedes-Benz is planning an engine change for the G500 off-roader.

Mercedes-Benz will allegedly drop the 387 PS 5.5-liter V8 engine of the existing G500 to make room for the 4.0-liter V8 twin-turbo motor borrowed from the AMG GT and C63. This decision has been taken in order to meet the incoming Euro 6 regulations which will come into effect in September. It's actually the same 422 PS (310 kW) engine configuration as seen in the G500 4x4² concept which was unveiled last month at the Geneva Motor Show.

We remind you that a major overhaul is being planned for the G-Glass and will reportedly come out in 2017 bringing a weight loss of more than 200 kg (441 lbs). The car is expected to be 100mm wider and should feature a three- or four-link front suspension, updated electro-mechanical steering system along with inline-six 3.0-liter gasoline and diesel engines which will debut next year in the new E-Class.
