manufacturers who have just developed “mild” hybrids to get around the old 2040 date are mighty upset.
Given that most manufacturers work on a 7/8 year cycle for each model, I don’t think the bringing forward of the ban has any impact on current models.
The industry needs some tough targets in order to drive innovation: My 1985 Astra 1.6D used to do 55MPG on a fast motorway run and my 2017 Golf 2.0TDI manages just a few MPG more. I am sure the Golf has far lower emissions, but fundamentally we have not really seen any huge strides in efficiency in more than 30 years.
