Frank-Steffen Walliser tries to grapple with Euro 7 emission standards. He sees an all new engine with a larger displacement and a turbo for the GT3 (possibly NA GT3 for non-Euro markets).

"In 2026, the next wave of regulations will come with EU7. This will be the worldwide toughest regulations considering emissions, especially in the spread between real driving emissions and what we see on the test benches. We will see a big change because it means for everybody, new engines and we will see bigger displacements coming back again."

Tougher regs on emissions yet bigger displacement engines? Makes no sense to me, unless you turbo the Hell out of it and mute the exhaust.

 

maybe you should read. New emissions are based on output per CC, so larger engines get more pollution exemptions....

 

Nice attitude. Having a bad day? Maybe YOU should read!!! NA engine looks to be going away, which was exactly my point. "The regulations are completely counterproductive to CO2 regulations, so this will go up.

"You cannot fulfil all the standards without spending fuel. It sounds crazy but it's a technical fact at the moment.

“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.

TURBO ENGINES

 

"At the moment, we only see a turbo solution. Naturally aspirated, not really,” he laments

Yep, I read all right.

 

which is bizarro and dumb, but emblematic of how the legislative sausage gets made. Let’s focus on the efficiency of the engines instead of their total emissions per mile so the trucking industry isn’t annihilated ....

 

to some extent the hp/liter is a mark of efficiency, but not necessarily fuel economy. Where an engine like the 4.0 liter in the GT3 probably will fail miserably is in cold start emissions. I bet the 3.0 liter twin turbo engine fairs better.
Disrespectful posts aside, I'm sure Porsche will come up with a good solution. And who knows, by then the regulations could be different anyway.

 

From the Article:

Just speculating here but a 5 or 6 liter NA flat six in a future GT3 sounds pretty interesting and a much bigger jump than what the 992 GT3 looks to be over the 991.2

 

By 2026 most of the cars will have some form of electric or electric assist, that will be one way to get around the emissions side and bump the MPG, and lower emissions.

 

lol. “Look, the engine is huge so we get an emissions budget on volume. True it’s variable displacement means it only runs like 3 cylinders in normal drive mode up to 55mph but let’s not quibble over technicalities ...”

 

Yep, this for sure. They are driving personal transport to electric.

 

And, maybe you should be less of a *****. Thanks for reinforcing the stereotype about Porsche owners.
