The return of bigger engines with EU7 coming into effect in 2026?

https://www.whichcar.com.au/news/big...coming-for-911

"I expect 20 percent more displacement on average for these EU7 capable engines. A lot of manufacturers will jump from four to six, from six to eight [cylinders]"

Seems to be missing a lot of details, like how bigger, higher cylinder count helps the issue of more stringent emission requirements.

Yeah does seem to be missing some info. The new regs will put a cap on relative power per litre, seems they aren't as worried about C02 pollution as before from what he says? I don't see how that makes sense though

Edit: He says catalytic converters would grow 3-4x size of what they are now...

Quote:
“This new regulation is really difficult to fulfil because we will have different cold start emissions side and bigger catalytic converters. When I'm talking bigger, I'm talking a factor of three to four times more, so there will be a small chemical industrial factory in the car to really control this," he says.
