Compared to the elegant symmetry of the twin-turbo setup, the T-Hybrid's long-term reliability and maintenance are likely to be a concern. There are a lot of undesirable asymmetries in the T-Hybrid's turbo connection and cat / exhaust pipes. The non-ideal, asymmetrical location of the single e-Turbo seems to suggest significant air pathway delta between the left and the right cylinder banks. The right cylinder bank, for example, may receive turbocharged air compression sooner than the left cylinder bank, resulting in momentary yet chronic air compression delays/differences between the two cylinder banks, as the turbo spools up or down. While this can be mitigated with electromechanical controls, this type of asymmetric pipe geometry is never ideal and is probably subject to abnormal wear and tear due to chronically-abnormal stress conditions caused by the inherent design problems.

Furthermore, the catalytic converter and the exhaust pipe setup also appear asymmetrical, with non-optimal convolutions that invite abnormal thermal stress hotspot developments. Moreover, the cat and the exhaust pipes are spaced way too closely together (and even with the engine itself) in a convoluted geometry, which makes thermal management-related reliability a real challenge in a daily wear-and-tear situation with the T-Hybrid setup.

Interesting innovation, I admit, but the airflow geometry here almost feels like a non-optimal afterthought in many ways.

 

3.6 single turbo, it's like 1993 all over again

 

Porsche must be aware of this and maybe has taken it into account in their design?...

 

Probably will be offering MSRP maybe even discounts because of non-asymmetry in engine.

 

The noise is the worse of it all. At least it's not a 4 banger?
If the TT and TTS follow suit, we'll have some fast angry vacuum cleaners out there.

 

I'd like to see what happens to the courageous guinea pigs. j/k

As consolation, they have four-year "free" warranty in the US.

 

You mean, like Audi?

 

Not forgetting the tendency lithium batteries have to ignite. But they certainly tested for that too. It's not like things similar to IMS bearing, GT3 fire, GT4 rod, PDK stumble, LiPo discharge would ever happen again.

 

They didn't take potential IMS bearing issues into consideration with earlier water cooled engines (996, 997.1, etc.), nor bore scoring!

One of the articles mentioned the water pump is now internal to the engine with the elimination of the drive belt. How complicated would it be to change a water pump on one of these new engines? Not to worry though, Porsche never has had an issue with water pumps on a 911 (think 991.2). There's a lot of other design concerns with this engine too compared to the current series and models. Definitely wouldn't want the first year of this redesign.

I do like the way the new car looks in the front, very aggressive and works well with the GTS trim. I'm curious to see what they do with the other trims like the next TTS

 

Wonder if the particulate filter is now standard for all cars (US 992.1s didn't have them)?

 

I'd be curious if they're monitored. 718s and GT3 variants have the filter, but it isn't monitored.

 

Looks like a good time for out of warranty.

 

Don’t forget bore scoring, GT4 front top hats and PDK distance sensor.

 

And intercooler sitting directly on top of the cat and GPF ???
