Default We Are Not "Over Weight!"

Just picked up a new Road & Track (Jan) which had an interesting comparo article including the '11 Z06 with CFZ and Z07 options. I was surprised to learn that the Z06 is ONLY 20 LBS lighter than the ZR1 at 3305 lbs. They said this was due to heavier shocks, wheels, and tires. The tested Z06 is 115 lbs heavier that the base Z06.

So, I don't want to see or here any more "Z06 is 200 lbs lighter than the ZR1" threads. In fact, it never was. My '08 3LZ Z06 weighed in at 3172 lbs on accurate scales (had 4 gallons of gas in it) and no "owner junk" inside. My owners registration card and Edmunds, lists the ZR1 at 3333 lbs, I have seen a few sources listing it at 3325 lbs.

We are NOT fat!

Default A little fat makes no difference anyway. ZR-1 rules.

I believe you are correct as a matter of principle. However, it really doesn't matter. When the Z06 was introduced it was about the same weight as the regular narrow body C6. They were forced to use the aluminum frame to reduce weight. The aluminum frame was promoted as a "performance upgrade". It was all about weight. The aluminum frame is inferior to the steel as used in the narrow body car and the ZR-1.

But that's a digression. My point here is about hp to weight. The Z06 has 75 more hp than the non NPP LS3. That is 69 hp with NPP on the 436 hp LS3.

That was promoted as a VERY significant hp increase for cars with very similar weight.

Enter the king...the ZR-1. It's been promoted as about the same weight as the other models until recently when this "200 lbs more than the Z06 cropped up". Sufficient to say all the C6 models weigh in very close.

I think the marketing strategy involved here is an attempt to downplay the HUGE hp disadvantage of the Z06 vs the ZR1 by claiming the Z06 weighs a lot less. You are pointing out that while the Z06 may weigh a little less it's certainly not a lot less.

The hp difference Z06 to ZR1 is 133hp. This is almost twice ( about 1.8 X ) times the narrow body LS3 vs Z06 hp difference. So, relatively speaking, taking all the C6 models as being "close" in weight it is clear that ONE , the ZR-1, has far more hp....far more hp more than the Z06 has over the base LS3.

Bottom line? The hp advantage of the ZR-1 is so overwhelming vs the Z06 that even if it WAS 200 lbs heavier it would still RULE.

The Z06 is a nice car, the narrow body LS3 is a nice car, but, neither is close to the ZR-1.

ps. I reread this post and noticed that , quite unintentionally, I had omitted mention of the GS model. This betrays what I think about the current C6 lineup. The GS is an "appearance' model and consideration of it in this discussion is irrelevant as it's performance is nearly identical to the narrow body model.

The ZR1 has the same hydroformed aluminum frame as the Z06.

Mag articles and numbers are rarely spot on and basing weight differences on their info is IMO asking for trouble

ZR1 is the King of the hill and there are always going to be cheap shots taken at it such as the 200 pound theory.

As pointed out ZR1 has the same frame as the Z06 and with many of the same upgrades in brakes shocks etc the ZO6 gains a lot of weight

Still I thought there would be more than 20 pounds difference.

Agree, it sounds like the Z06 is actually a ZR1 with a Z06 engine. Close anyway. Do the ZR1 badges weigh more?

The ZR1 does have an additional badge on the rear bumper that is adding extra weight.

There has to be more than 20 lbs. difference. The blower and intercooler weigh more than 20 lbs.

Although we have different scale across the nation....
A full tank of gas and go weigh each non-modified model.
(Gas is 13 lbs a gallon, yes?)

Seems to me fully loaded (full leather dash, HUD, XM, CD changer in trunk, pass elec seat) with options and a non-optioned model would be a minor weight amount and may not need to be disclosed/ itemized in gathering the answer to this weight debate.

Auto gas is approximately 6.15 lbs./gal. at 20 degrees C.

The interesting thing is that in this article, the "specifications" section lists the Z06 weight "as tested" to be 3485 lbs. Suggesting that it is only 20 lbs lighter than a ZR1 makes their statement of weight for the ZR1 at 3505 lbs. Seems a little heavy. I think I will take mine to a reputable scale and find out!

The "as tested weight" included the 180 lb driver. Subtract 180 from 3485 and voila! ---- the 3305 Z06 weight referred to in the article.

Correction noted. I thought the ZR-1 used steel frame rails along with various magnesium components and aluminum for the rest of the body. My opinion of the car is now just a bit lower with the knowledge that the main frame rails are not steel.

Only time will tell if the welds will hold or if the frame will twist. Aluminum is light but more difficult to weld and not as strong as steel.

My 08 1LZ Z06 weighed 3060lbs, headers were the only weight reduction. Not quite 200lbs lighter.

I don't have a GS (just a Z06 and a ZR1), but I think it's FAR from just an appearance model!!!

It's performance may well be similar to the base C6, but when a Grand Sport coupe is ordered with the manual transmission the car gets a hand built forged crank LS3 on the same line as the LS7 and LS9. Dry sump is also included. It has the larger wheels/tires and the larger Z06 brakes.

It has the steel frame, and I think that if I were building a T1 track car that the GS would be an outstanding platform to start with!!

I think it's an excellent addition to the C6 lineup!!

Seems to work pretty well on the GT1 and GT2 cars............
