These guys are supposedly working on it with OEMs (not sure which ones).

I'm hoping one of these fancy multi-point ignition technologies gets the naturally aspirated high revving engine one last upgrade before everything goes electric.

My post was 100% pun.


And yes, I did check out the link.

With the ginormous bores Porsche uses and the high rpm these run at, there is a bit of room for improvement from higher combustion speed. I wonder if it's possible to tuck extra spark plugs into the head. A better but so far unproven method would be corona discharge ignition. In fact since the GT3 uses high overlap fixed profile cams, corona discharge ignition would be very useful for idle stabilization and fuel economy as well.

I don’t think it needs more power. If they saved money on engine development and just passed that on to the consumer in light weight components then I would be fine with that.

I hate this trend. It’s funny when you compare 1960s-1990s sports cars to their post 2000s successors just how much bigger the new ones are. The old ones are low, petite, light, and usually look so much better. The new ones are wide, long, tall and heavy. Yes, massive power gains, trick suspension, and tyre development mean the new ones are so much faster than the old ones. And they’re much safer, of course. And more comfortable etc. But something has been lost. Not least the ability to park in small spaces!

I’d love to see a wider return to the Lotus philosophy for sports cars. All the advances in material technology and design mean you can ‘add lightness’ without sacrificing strength and thus safety. Some cars manage it - MX-5, A110, 4C, Elise etc. I just wish more auto makers would pursue that trend, and try downsizing their sports cars with each new generation for a while instead of upsizing every time.

Yea I agree, I don't think it needs more power either, but Porsche usually increases power with each generation, and now they've stopped (because they can't find any more power, presumably). The bore is about as big as it can get, it has solid lifters for maximum rpm, etc.

I totally missed the corona pun but as I understand, corona discharge or "low energy plasma" is essentially a much higher voltage and a bigger "gap" (well, the ground becomes the cylinder itself) that's switched on for a shorter period of time, and the free radicals produced in a bigger space will speed up flame propagation. It's kind of like having an enormous spark plug. The other promising high energy ignition technology which is actually in production is of course prechamber jet ignition (Mahle).

These should give NA engines one last huzzah because they are better at burning the highly diluted mixtures created by high overlap cams at part throttle.

They could increase displacement, but I don’t know if more power is necessary.

Porsche makes the 911 larger and larger to attract a wider range of buyers. Whereas the vaulted Porsche of old (which was sadly always financially shaky) could sell the 928 to buyers seeking a cushy GT experience, today we don't have that. The 911 is the do-all swiss army knife in their arsenal. The 911 would be such much better off if they came out with a new 928 (basically a 2 door Panamera) so they could stop the bloat.

I'm not remotely a fan of the 992. It looks like a 991 that ate a 993. And making them all "widebody" makes it even worse. If someone handed me a blank check to buy a brand new 2021 Porsche sports car, it would be a Cayman GT4 or GTS, which is the closest thing they currently build to a 911 from 20 years ago.

Add a custom gearset for street driving too if you got that blank check. The Porsche gearing is dumb if you're never going to go past 165mph.

[WolfpackS2k]

Good call, lol.

You don't have to tell me...my Cayman has the EXACT same gearing, and 100+ fewer hp.

Rumors on German porsche forums this car bested the 991.2 GT3RS time of 6:56 at Nurburgring. Thoroughly impressive if so.

I'd like to have a batmobile. Then I wouldn't look so weird while wearing my cape.

Oh you will still look weird.
