I can't say I know what other manufacturers were doing as I didnt have anything on order from them, only Mercedes. This time last year due to WLTP testing and the incoming average emission quota all V8 AMG cars were in very limited allocation, they had to get overall average down to 95g/km from 120g/km in the space of 12 months for 95% of the fleet. That is due to sink further by 2025 to 65-70g/km. (can't remember where I read this). The new models get tax breaks for meeting the next upcoming legislation, I'm no accountant but 1 V8 AMG car equals at least 25-30 Battery cars. How many EQC's have they sold in the UK.............?
I would say this is the real reason why Moers has gone to Aston with his own money thrown in. Aston and Ferrari, amongst others, won exemptions in 2016 as limited manufacturers, and the exemption runs through to 2031. A prime company for Mercedes to invest in just for the quota, which are indeed transferable to 'partner' or 'parent' companies, as FCA just did with Tesla.
Its outright corrupt bullshit is what it is. Parasitic socialist lefties intent on controlling whatever they can whilst trying to pick everyone's pockets and telling them its for their own good. (For clarity, this statement is relation to the EU and its emissions regulations)
