The last paragraph is where the author speaks about his opinion on changes to come.
From the article: "For lovers of unwieldy paramilitary luxury, the bad news is that the gas-powered G-Wagen is doomed. European emissions rules will kill it, kill it with fire. I give the civilian version four more years. The good news is that none of the G-Wagen’s ass-kicking charms need be lost in the model’s inevitable conversion to electrification. As the Cybertruck well shows."
It's seems that unless MB does something better about fuel consumption it could potentially become a victim of future European fuel regulations.
