Most states are now doing things to combat the Montana ordeal. Not illegal but illegal lol.

Everytime I watch a Youtuber from CA they never have tags lol. (Vehicle Virgins and Salomondrin).

Interesting - but I would make the argument that the car does not belong to the "resident". The law is really designed for individuals who don't register their personal cars. And that's because the state is losing the registration fees. And California sure needs more money.

To them, that doesn't matter. What matters is the fact that the vehicle is domiciled in the state and using the state's roads, etc. So the law's justification is that any such car owner should shoulder a fair share of infrastructure expense. Regardless, that doesn't matter to me. In Texas, car registration is downright cheap!

I am not versed on CA law lol, I have read where a ton of guys with exotics do not register their cars and run around with tags promoting a business or something.

i think its unreasonable comparison... the 720s is pushing into hypercar performance, people keep comparing the 720s's numbers with other supercars and then shame the other supercars for losing, it is quite unfair to the other cars... it's not that the other supercars are not good, the 720s is like in another category with its specs. You have to remember the materials and engineering in this car, it is why it costs way more than the ZR1 and some other supercars, they need to make it better enough to separate it from the 570s which is already one of the quickest supercars. We have to take into account the weight and aero for cars like this, horsepower alone doesn't mean much, mclaren and porsche proves this many times. TBH it is too easy to overhype the 720s because people keep comparing it with entry level supercars when it is a step above that creating a class of its own, the 720s because of its aero and weight, is one of the fastest in straight line acceleration period, it shouldn't surprise anybody... but around the track it might be a different story, that's where the track focused lt version will come in and it will be a crazy track monster, they have to leave room for that beast.

also... people should realize the ZR1 and ACR are track focused cars, meaning they are meant for lap times, the engineers designed them more for the track rather than going fast in a straight line, so stop racing them in a straight line and crying about losing to better cars for that purpose and go to the track to enjoy them more. Don't go talking trash about the vettes or other supercars, we should appreciate all the engineering and magic put into these cars and be thankful you are lucky enough to own one.

Very well put. I wish others would understand this...

I have tracked the 720S extensively, and even though this is the "base" non track intended car, it performs impressively, esp on a track like CoTA with long straights. The suspension is fantastic, and it's very forgiving even near the limit. A regular 720S with sticky tires is very formidable on track. Can't imagine what they have in store for the LT version.

yea the 720s is obviously still a track day weapon especially if the track has long straights, but the LT version gonna be the absolute monster, pretty scary to imagine lol

I can tell you where the difference is

We measure on our test bench according to the DIN standard
As a rule of thumb to convert from DIN to SAE PS you can use the factor 1.02

All GM vehicles usually have much less power than promised

Here are a few average numbers of what I am doing at the engine

C6 ZR1 = ca 580-600HP it lacks about 40
C7 Z06 7G = about 600-620HP missing about 50
C7 Z06 8A = ca 580-600HP there are about 60 missing
The new C7ZR1 I could not measure, because our car has not come, I'm already sure there will be at least 50 more missing

As comparison

Porsche GT3 450 HP I measure 450
Porsche GT3 500 HP I measure 500

MC Claren 720 = I measure 760

I went from a z06 to the 570s Biggest difference between the z06 vs any mclaren it’s much easier for a novice to find the limits in the mclaren, I bet a z06 is faster around the track but only in the hands of a pro.

If you have never driven an exotic and only going on specs alone you will never understand the difference between a Chevy and Mclaren. once you drive the exotic I promise you will understand why they cost so much!!

Not an engine dyno, that's for sure. Which makes the power numbers an interesting comparison, but pointless for saying the "GM vehicles usually have much less power than promised"

Does that include Mustang owners! You know the elite car that owners are so hi on them they judge against all the other lessor Corvette's and other lessor sports cars!

Sorry - don't agree. I drove a 458 - nice !! and the 430 - 430 interior looks like a kit car, never mind the crappy tranny is has, that jerks your head between shifts. the 458 a different story - nice interior and dct.

Different folks can have different experiences. I have driven a McLaren MP4 (hoping to love it because I thought it was beautiful), 458, and Aventador at Exotic Racing, LAS. I feel more comfortable in our Z06 than the MP4 (it was twitchy compared to the Z, not a knock and not a surprise considering the chassis configuration) The 458 handled well, but not any better, and is down on torque to the Z, and the Aventador sounded great but when the transmission shifted you needed a neck brace it was so harsh-would NOT be fun on the street.

So my wife and I have 8k on the '17 Z, more than half of those miles at the track. I would love to see any of those cars just mentioned come to our local HPDE for a little friendly amateur comparison
