Porsche's Idea for a Six-Stroke Internal Combustion Engine Looks Brilliant

I need to check that source but I guess is heavily per country. In Southern Europe is under 5%, south from the US border between 0 to 1 % (source: per country Car Makers Association report)

Globally, if I recall, you need 20 years to replace the whole global fleet (so around 5% replacement rate). Let’s assume this global number is fixed (installed base is growing, as more vehicles are being created that destroyed, actually)

1/7 is 15%. 15% of 5% is 0,75%. So this means that every year 0,75% of global installed base is replaced by EVs. So 130y for full replacement?

Yes, the 1/7 weight will increase. But so will expand base. Even if suddenly today every car made now on the planet is EV only, iCE will still be around for 20-30 years.

Not to pile on, but the linked article you presented backs their data on New AutoMotive’s Global Electric Vehicle Tracker, a UK based group fostering EV adoption.

NAGEVT site only shows data for UK, is unclear which data sources they used, and whether they added PHEV (still ICEs) into the mix.

Don’t mean to come obnoxious, I just spent a few weeks researching the topic for 10 countries and my data differs a lot from theirs.
