ZR1 vs. 911 Turbo - Motortrend
 

I can't be the first to post this.....

I bet the ACR would beat the 911 T.

Good read - thanks for posting!

That's a given... :D Maybe the C&D Lightening Lap will include all the big players this year (ie - 2010 ACR, ZR1, GT2/GT2RS, GT3/GT3RS, 458....) That's what I'm waiting for. IMHO, this test is more accurate than most when providing race times that replicate what I've witnessed in the real world when comparing car A to car B.

Anyway, I was p*ssed to see the 911T broke before the 1 mile run. I think the ZR1 would have had the edge, but it would have been interesting to witness. A side by side run would have been really telling...

Thanks--I had not seen this before.

I really enjoyed that read.

The video was cool, but sucks that the Porsche broke. Not sure what happened to it. I wanted to see what speed it achieved in the mile on that same day. Grrrr


I sure am impressed that in a minute and a half track, the ZR1 was over 3.6 seconds faster. I didn't expect quite that much of a lead, but the driver was obviously experienced in both cars. The ZR1 just had more grip throughout those turns. It looks like a lot of the turns were long enough for the ZR1 to take advantage of superior lateral G performance. Driver also mentioned how he didn't have to shift the ZR1 as often.

Driver mentioned the gearing of the Porsche several times, and I wonder how much time he could have made up in the track if he had the 7 speed tap tap box... :) I'm sure it would be a bit faster, but not nearly 3 seconds.

Anyone find out what exactly broke on the Porsche in the end? I was really impressed with this review. Professional diver, experienced in both cars, fair game. :) Wish more reviews were this well put together.


Interesting Quote from the driver.


Justin went out first in the ZR1 and laid down six hot laps for our data junkies, three with the PTM in mode 5 (see sidebar), the most aggressive setting, and three more with every handling aid turned off. The results startled us. Mr. Bell cracked off a 1:29.69 around Big Willow's 2.5 miles with the PTM in Race Mode, and 1:30.11 with everything in the off position. This confirms Chevrolet's assertion that PTM will make a good driver go faster. Said Justin, "If I had 10 laps and was told it didn't matter if the car came back in one piece, I bet I could have gone faster without." Still, the results are the results. The Porsche Turbo, meanwhile, was a good deal slower, with Justin's best time being 1:33.31. That's over 3.6 seconds behind the ZR1. After we told Justin his times and the discrepancy between the two, he commented, "That's not even the same class of car." But before your flag-waving heart explodes with pride, Bell said he'd rather own the Porsche.

PS: This gives me a real positive outlook for the PTM system in the 2010 + ZR1.
If Jan runs the ring in the 2010+ ZR1 and not the 2009, (nothing against the 2009, just doesn't have PTM), I can only imagine how nice a time it would kick out. Now I surely do not doubt a faster PTM optioned ZR1 time with Mero, and even lower with Jan. Good stuff!

Wow that was just amazing. Thanks for posting. I can't believe the ZR1 was over 3 seconds faster around track.

Wow simply astonishing. This makes me want to buy a zr1 so bad. Interesting that this video played right into two recent threads on this forum.
1) Handling. Seems like the zr1 not only grips hard but also has good nature handling. This agrees with the autocar video in which the zr1 and lp640 played together.
2)Seats still suck!
Like the 911, it seems GM has been slowing evolving the breed and perhaps the next iteration of the corvette will be pretty darn close to perfect. (Where I imply that the team of engineers knows there way around suspension tuning, and enhancement of dynamic handling through software. They just need to address a few non-lap time related issues.)
Fair review. The 911 embodied almost all the typical American car stereotypes too lol.

The ZR1 was only .3 sec off the ACRs time at Willow.

The results were about what I expected. The 911 TT faster from a standing start with it's awd and the ZR1 faster everywhere else. I would bet at a drag strip where the ZR1 can get some better traction it would also win. Thanks for the link.

After the first or second page I thought to myself "Great another pi$$poor review with a winner before they even started" but I was actually suprised. CD didnt do to bad. Interesting how they saw the trap speeds and decided they wanted to do more test.

Since in that day the 911 was about .5 seconds faster than the ZR1 in 0-60 time, I wonder something..... Did the race lap begin from a standing start? If so, the ZR1 likely made up the .5 time that the porsche had from the lead also. That would make the ZR1 over 4 seconds faster than the 911 around the track. Someone tell me that's not the case please, because that's just embarrassing if so.... :eek:

Yeah theres been a couple to run 10's there first time out.

I can.

500 hp vs 638 hp
480 lb-ft vs 604 lb-ft
3500 lbs vs 3329 lbs
steel brakes vs carbon ceramic
235/305 tires vs 285/335
RE050's vs PS2 ZP's (PS2's are an alternative Turbo spec tire)
92.5 in wheelbase vs 105.7 in (on a fast track like Big Willow, longer is more stable)
2+2 with engine in the wrong place vs 2-seater

C4 ZR1 was also faster around the track than a 911 Turbo back in the day, as was the C5 Z06...

Agreed,

A More appropriate match for Porsche on the track would be the Z06 with a Z07 package, or a Z06 carbon. Either way, I am very surprised with the shear time difference.

As Justin (The driver said), They are truly not in the same class. The Porsche is outmatched in all categories except launching, which accounts for it's lead in the 0-60 time, and ultimately it's 1/4th time.

I wonder why MT would test the Porsche on a race course without getting one that is properly equipped. It's like they sandbagged the car..

Major missing features:

1. Torque Vectoring

2. Ceramic Breaks

3. PDK Transmission

I just read the story again and the Turbo had the Torque Vectoring system installed.

Still
They could have equipped the Porsche better indeed with the Ceramics. I think due to power differences, the porsche would have been better matched if had gone against the Z06 Carbon, or heck even a standard Z06. The new GT2 will be a better match for the ZR1.

Didn't a PDK equipped car do the 0-60 in 2.93 seconds? This guy is a hell of a driver with click off a 3 flat in a manual car. ZR1 sounds the part so much better as well. Listen to that ROAR!

The ZR1 does not stand a chance...

Why?

I still think it's better to compare the GT2 to the 2010+ PTM equipped ZR1 than the regular 911 Turbo when it comes to most courses.

Especially when you can see what professional drivers can muster out of the PTM ZR1 on the courses.
