Quote: The ZR1 got a better launch than the GT2 (faster 0-100 km/h time) and the GT2 had to play catch up. From 200 km/h to 300 km/h (124 mph to 186 mph), where I guarantee neither car was spinning, the GT2 was still faster by over 3 seconds. That is very impressive.

ZR1 200-300 km/h: 22.3
GT2 200-300 km/h: 19.1

The GT2 RS deserves some credit.

Just call it an "FRC" - Fixed Roof Coupe



I think that is a matter of managing heat soak and the efficiency of the rear-engine layout.



I agree with that. Here is my review of a pulley swapped ZR1:

Uhhh only Vette owners really know what FRC really is. FRC has two different names. First is what you said, other was the original name for it being "Factory Race Car" because it was light weight (100+lb difference) compared to the coupe. Please don't try to educate me on Corvettes as we have a 840+rwhp "FRC" sitting in the garage of my brothers house at the moment! LOL!

I wasn't debating which car is faster from any speed, I was simply stating as an owner of a ZR1 I know the traction on street tires is seriously limited even on a prepped track much less the steet.

Quote: The GT2 RS more than deserves credit , it demands credit for its performance! The only reason I was asking is because I would imagine the GT2 to have closer to 700 hp than 620....because at those speeds...its POWER...POWER...POWER...drag...and gearing.

Not really. The RS is a couple of hundred pounds lighter than the std 997gt2 and has nearly 100 more bhp. According to fast lap times the std 997gt2 did 0-300kph in 33 seconds, which is a .4 seconds slower than the ZR1. Does the stock GT2 have more power than stated or is it that the drivetrain loss in p-cars is much less than in chevy's and that it is noticeable when power goes big.

It's still drag, there is mechanical drag (same as drivetrain loss), and then aero drag. Is it a T-56 in the ZR-1 like the Viper? Those things do sap a lot of power. I would bet the GT2 is losing quite a bit less through the drivetrain.

Also is the ZR-1 roots style SC? Any parasitic loss there?

So a $250k car is slightly faster than a $105k car. Also, the interior of the GM is not as nice as the Porsche's. Good to know.

I can't believe I just read all 9 pages of this pointless bable... Shame on me.

It only matters to those who care about price...

But then again, performance only matters to people who care about performance.

Sometimes - these two types of people do not overlap.

What is the explanation why in a 1/4mile race a faster car sometimes traps lower speed then the slower car ?? help please

We all know that the 620 bhp from Porsche is understated.

You can read hundreds of threads on this subject and it always ends the same.

You started all of this.

It's obviously not as simple as price vs performance.

Should the GT2RS be faster than a ZR1? At $250k+ it damn well better be faster.

Should the 997.2TT PDK be faster than a Z06? For $135K base and $165K well optioned - you bet.

Should the GT3RS be a freaking track terror? At $165k off the showroom floor - it should be an incredible track car.

No matter what - in the end - money counts. Well - at least to most of us.

If the Porsche guy can complain about the interior and seats of a corvette they should be willing to accept the bang for the buck arguement.

Same goes for the Corvette guy. If he can bring up the bang for the buck he should also to know the quality issue is going to be thrown back in his face.

That usually has to do with how well the car launches and sometimes gearing and traction down the track. Launch is usually measred in 60' time. An improvement of 0.1 sec in your 60' time can equal 0.2 - 0.3 sec improvement to your 1/4 time. Time to distance and time to speed are 2 different things. Just because one car reaches X speed first does not mean that it is ahead on track. If a car has a poor launch or has a tall first gear it and then gets traction or goes in to a better gear which causes it to accelerate faster than the other car it is possible for it to be traveling at a faster speed but still be behind the other car on track.

I deal with the price excuse all day everyday with my brother and a my friend both corvette drivers. If they were faster price would never come into play LOL
Silly vette drivers

Agree, and like they will readily mention themselves, if GM actually put some quality parts on the car it would cost a lot more too. Pleather seats in a 100k car is unacceptable. The EXACT same interior as a 40k car in a 100k car is also unacceptable.

If Porsche wanted to take as many shortcuts as we ALL know that GM takes, I'm sure they could knock a good 100k off the price.


Plus Porsche likes to make money, and is smaller volume, therefore prices will be higher. GM hasn't proven they like to make money just yet.

^ Along those lines could you point out the differences between the $80k C2 interior vs $140k Turbo interior (same $60k delta in the C6 vs ZR-1 comment).

(Not sure if I have a point here - I really don't know the differences anymore, I've been out of the market for a couple years)

*edit: For that matter - what is the difference in interior between a C2 and a GT2RS?

These are brand ******, not car enthusiasts. They chose to buy a porsche and are going to be ignorant about other cars' advantages.

It's blatantly obvious that you can take ANY porsche, and for the equivalent price, the Corvette option will blow its doors off on a race track or a drag strip. This is un-debatable fact.
