The M177 twin-turbo V8 in the G550 is remembered fondly as one of the best engines owners have driven, and its discontinuation is a recurring value argument: commenters note 2024 was the final V8 G550 (the 2023 and 2024 being the same vehicle), with the engine giving way to a smaller inline-six for 2025. For some buyers the V8 is the only proper G550 powertrain, and 'last of the V8' is invoked as a collectibility hook.
