Yesterday, in the Ask Tadge section, Jim Mero responded to the Question of the Week. In it he mentioned that with the new calibration setting upgrade the ZO6/Z07 did a 2:39.77 at the VIR Grand Course. That breaks the Viper ACR record driven by Chris Winkler. Prior to that, Mero had the VIR record at 2:41.32 then the new Viper ACR broke that with a 2:40.02. Now Tadge has said that this new ZR1 is 2.5 seconds faster than Mero's time of 2:41.32 = 2:38.82. WOW !!! Faster than the ACR by 1.2 seconds. This ZR1 is going to kill the Laguna Seca record held by the ACR.

It better kill the ACR with about 3 years extra development and 100 extra HP. I love seeing American cars keep these records.

The new ZR1 is going to smash track records all over the world!

Does Languna Seca care about the louder exhaust on the ZR1!

The 2:39:77 VIR Grand Course Time was for the updated Z06/Z07. I didn't see a time mentioned for the ZR1 for the same course ran on the same day. The previous best time for the Z06/Z07 was 2:41:32. Where did the comment about the ZR1 being 2.5 seconds faster than that come from?

Even then it might fall short of the new updated Z06/Z07 time.

Tadge told Car and Driver that the zr1 was faster than the z06 by 2.5 seconds around the shorter "full course?" VIR configuration. One can "do the math" to extrapolate a delta for the longer grand course. It also raises the question of whether the 2.5 second delta was with the z06 before or after its update. Either way makes the zr1 bonkers fast

meadowz06

There is NO way the Z06 beats the ZR1 on ANY track of any kind! Period.

Poor-sha

I remember that as well but I believe the ZR1 was 1.5s faster on VIR Full and 2.5s on Grand. That puts the ZR1 around 1:53.5 on Full course which is 4s faster than I've ever gone. I really wish GM would make some if these PDR files available to download and compare.

She better be an enigma of epic proportions!

skank

During the Dubai intro he mentioned it.

sunsalem

Exactly.

Yes, they normally do.

I think I'll wait for a source a little more, uhhh, reputable before uncorking the champagne.

October issue
Chevy’s team uses a different track configuration than we do for Lightning Lap but says the ZR1 laps VIR 2.5 seconds quicker than a Z06. If we can replicate that performance on the longer Grand West Course, the ZR1 should set a new Lightning Lap record.

SEMA October 31 (2:29.77!?)

4.2 Grand Course 1.50s faster than 2:41.32. So 2:39.77 - 2.5 = 2:37.27; the C6 ZO6 was 4.25s faster than the C5 ZO6 at Willow; but, the ZO6 is getting most of this back with a simple software upgrade (ZR1 Level!?) in a month - LOL

2:37.27(157.27s)/X = 2:40.02(160.02s)/7:01.3(421.3s)
X=6:54.06(414.06s); beats the 918

GM needs to go to every major track in the usa and the world and set new records,then go back to texas and beat the 1990 zr1 records too

You know Motor Trend will get a GT2 RS and the ZR1 at Laguna Seca with Randy Pobst driving both. Then we will see where the ZR1 stands in the grand scheme of things. After all, they have a lot of data on the ZR1 after 3 days of testing last spring

sunsalem

Randy will certainly wring the 2 out at LS.
It will be interesting.

johnglenntwo

The Le Mans C7R Team over there won't have an excuse Now! They are all faster than Mero, right Skank!?

We are definitely clueless at least until then!

Achmed

the text on the video had a typo - 2:29.77 was meant go be 2:39.77. That's new z06 time 2.5 seconds faster than the old z06 time of 2:42.32.

Jim Mero summarized the old vs new z06 and GS times in a recent post in the ask Tadge section.

johnglenntwo

Therefore, the new ZR1 is 1s faster than the Z06!? I hope not!
That would be pathetic!

Achmed

lol it's a wash because the extra 105 hp comes with 36 lbs of weight and both cars use the same tires.

Jk

These are the latest times claimed by GM for the z06. They also claimed the zr1 is 2.5 seconds faster than the zr1 at the shorter full course, implying about 1:53.5

Achmed

but production corvette weight distribution is based on the assumption that the an extra Jim Mero weight man is in the driver seat and passenger seat must be empty. Therefore advantage = Mero over Gavin
