This info is pretty informative and mostly over my head, but...your quote below it as to the specifics of why you chose an auto makes me chuckle!��

There is one reality in ICE’s that people, and manufacturers, often ignore as the biggest two variables in making power is RPM & dynamic compression. Those things being largely limited by thermodynamics. They find the limits, but I’m not convinced yet they know as to why they reach those limits. Maybe they do know the solutions & choose to not pursue surpassing them.

The rest of it is what is around that power plant, whether talking straight line performance or curves, that also greatly matters.

Engineering, as an absolute matrix, requires monetary expenditures. To this there is no exception.

Hence the reason you see “better” engineering in vehicles that slightly outperform the Gen6 chassis, but at nearly double or even triple the cost.

There’s always a point of diminishing returns as an inverse to expenditures.

That being off-topic either way, if HPE has fixed their reasons for the bad rep they’ve received over the years, then OP should do what he wants & anti-up on an Exorcist.

I Bought the ZL1 2 years ago and still find it a great daily driver car and never regret buying it. Frankly the depreciation is something I have never experienced before!.. such great value. But, engineering wise, I keep comparing it to the GTRs (R36) which was introduced in 2007 with a 3.8 twin turbo V6 & the 991 GT3s which was lunched in 2013 with a 3.8 naturally aspirated V6 pumping out 470 hp!!. Then came the Zl1 in 2017 with the supercharged 6.2 v8 engine which in my opinion did not "evolve" as expected! Its all about how you put that power to the ground and I honestly find GM behind! I am sure things will change with EVs.

I'm confused, you keep comparing vehicles that are in the $130-150K range to a $70k vehicle and disappointed that the $70K vehicle doesn't perform quite as well. Do you realize that you're comparing a rear engine vehicle and an AWD vehicle to a RWD vehicle and complaining that the RWD vehicle is harder to get its power down? The C8 Z06 is going to blow both of those cars away and do it for less money. For the record, the GT-R is slower than a ZL1 1LE on the Ring.

And a top speed of 147. WooWee!

I'm not exactly a Hennessey fan, but let's not get carried away, that's an embarrassing mistake on the author's part. 147 mph is the Exorcist's speed at the end of the quarter mile. Top speed is in the 207-212 mph range if I remember correctly.

You are missing the point again! Go read my replies again

Nope, that’s exactly what you said. Your comparing “engineering” in a 140k GTR to a Camaro ZL1. What point did he miss?

Here is a small story for you: in April 16 2018 GM decided to break a new record for their new C8 ZR1 and managed to Book the Nurburgring for the whole day. A full racing team arrived with 4 ZR1s and started doing laps for the new record. Same day, Porsche arrived with 2 GT3 RS, 2 drivers and an additional set of tires for each car, they granted permission from GM to use the lap during their one hour break. Porsche did 4 laps in that hour and break the record every time! till they did it in 6:56! GM guys were watching that happening and couldn't believe their eyes! later GM decided not to reveal any numbers!! I am comparing two RWD cars with about 30k difference in price. I guess size no longer matters anymore! This whole story defines knowledge

In my opinion, GM didn't develop their engineering skills compared to other manufacturers.

There is no C8 ZR1 yet, there is a C7 ZR1.

Chevrolet took the front engine RWD platform as far as they could with the C7 ZR1, and then decided they had no choice but to move to mid engine to continue to progress. They're doing exactly what you're saying they aren't doing. There are NO other front engine RWD cars doing what the C7 ZR1 was doing and certainly not at that price point which is why I stand by my statement, Chevrolet has the knowledge to build world class performance. Chevrolet has long been providing vehicles that PUNCH way above their price point in performance. As I stated before, the C8 Z06 and ZR1 are coming so Porsche has a lot to worry about.

Correction: C7 ZR1 2018

I definitely know what I am talking about! had a typo with C7 .. of course at that time (2018) .. its only C7 there and nothing else! you are just being emotional
