Porsche Macan Forums

Not surprising, this is what’s creating it
“We will have bigger catalytic converters by a factor of three to four – there will be an industrial chemical factory in the car to control emissions […] the main reason [for the displacement increase] is because it will take relative power per litre down”
Adding considerably extra complexity, weight and bulk. SUV’s and high performance cars will be first to fall.

In the same way the EU introduced catalytic converters in the early ‘90s, effectively stopping lean burn technology from progressing.

The confusion why Porsche spent money creating the 4L engine for the Boxster becomes clearer now. Pop a set of turbos on it and theres you new 911 engine maintaining power even with more exhaust cleaning gubbins attatched.

Just then have to find where the extra cleaning gubbins can be hung, can see the rear seats disappearing soon

Oh well, we will have to by the last flat-six model available before 2025. I am already plotting replacing my Macan S with 911.
The regulators might just force my hand... it’s hard to pretend that its not exciting
