Holy crap....lol....one guy was down to 3760 on an SS....I'm giving myself a headache....Think I'll just go with what the factory comes up with...lol..

With all the "improvements" added over the last four Model Years, a 6-speed 1SS has swelled to over 3900 lb. An Automatic is now near-4000...

...with the addition of the LS7 and associated plumbing I recall they mentioned a weight addition. There was nothing much of susbstance to be architecturally removed from the C5 other than what they did pull out of the car. They even lightened the rear window glass in an effort to save a few pounds. Would I have liked to see more weight removed, heck yeah! But, they were handcuffed at what was on the table that could have been taken off. Alot of thought I think went into this for a 300 pound reduction.

My 1SS 1LE with NPP, BA Stereo and back up camera weighed in at 3823 with 3/4 tank of gas.

I think a lot of the curiosity is really what is the lightest these Gen5 Camaros could weigh.....(without getting into the absurd, of course).....The overall weight of these cars has always been sort of a negative for one reason or another...

Just thinking if this weight removal engineering is viable, perhaps it could translate into a lighter-weight 1LE or SS track model...
or even as an "option" for the 6th Gens, if too late for the rest of the 5ths...

In discussions a year or more ago about weight possibilities for the 6th gen Camaro, we talked about the overall weight reduction on them based on what GM engineering was doing from the ground up on the new Cadillac ATS. They focused on weight reduction everywhere looking at grams and ounces instead of pounds, a program that would not be cost effective for a platform that was soon going out of production like the Zeta is (though I think there will still be some limited Zeta use for the police cars?). Every model built on the new Alpha chassis will benefit from what was done for the ATS, so the 6th gen. Alpha Camaros will be much lighter than the 5th gens.

Yes I agree. I was surprised it was over 3,800.

If you start with a 1LE and add/subtract the items they did I thought we were looking at 3,750(?).

Just FYI....From the 2014 brochure in the other tread...

1SS manual coupe..........3,908
SS with 1LE package...... 3,875
ZL1 manual coupe..........4,120
Z/28 (300lbs<ZL1)..........3,820....or 3,837 (283lbs less)
...no chart for Z/28 curb weight....just 300lb less statement...

For sure I recall the new platform and all that as being a tremendous weight reduction plan in and of itself for the 6th Gens...

I think what I was trying to ask, is if the weight removal we see from the Z/28 couldn't be an additional option for even the 6th Gens on models other than a Z/28...above and beyond what they have planned for the 6th Gens....

My 1LE is sort-of a stripper. Very similar options to Dropspeed's car. 1SS, 1LE, NPP, BA audio. It said 3801 on the registration. Not sure how accurate it is.

I don't think there will be a whole lot of areas for further weight reduction on the 6th gen. Camaros. With their new weight reduction engineering and mindset they are already looking at things like lighter material for interior door panels to give you an idea of where they are going. They are looking at every area to save an ounce or two here, an ounce or two there and overall the numerous small weight reductions will add up to a significant weight reduction.

I know, the weight thing seems it can vary...curb weight, dry weight, gross weight...whatever...lol....

This is one of the threads from 18 months ago or so where we discussed the 6th gen Camaro weight. I'll quote one of my posts but there is much more info in that thread.

"Given that the original numbers were taken from somewhere other than a GM press release, I went and located the official GM press release to verify some numbers.
"All three engines support the ATS’s agile and lightweight driving dynamics. With an estimated curb weight of less than 3,400 pounds (1,542 kg), it offers a more favorable power-to-weight ratio than key competitors. With the 3.6L V-6, for example, there is 1 horsepower for every 10.8 pounds of vehicle weight. That’s better than a 2012 Mercedes-Benz C350’s 11.9:1 ratio or the 2012 Audi A4 sedan’s 16.6:1 ratio."

Now if you plug in their 320 est. HP to their 10.8 lb per HP, you come up with 3,456 lb for the DOHC V6 ATS. Now plug in my numbers from earlier where there was 70 lb difference between V6 manual and SS manual (and they are currently talking about the DOHC V6 in the ATS with auto only, no manual which would make an even better number for us), then you arrive at 3,516 lb for a V8 version. And if that translated exactly to a 6th gen Camaro, we are still at 333 lb less than the current SS manual. Go read some of the press release about their weight reduction strategy, every part of the car was looked at for weight reduction, they concentrated on reducing weight by grams not pounds throughout the car, the made use of high strength steel and ultra high strength steel to allow parts to be thinner/lighter yet as strong or stronger. Almost all of this should move over to the 6th gen Camaro, I think the naysayers will see a difference if they look carefully at what GM has done with the ATS. These weight saving steps are a mere glimpse of GM's future production techniques.

Given the weight saving engineering already done, I don't think there is going to be a wholle lot of areas left for significant weight reduction.

Nice Clyde, thanks. I guess this 5thGen Z/28 weight reduction is all this type of thing we'll see for the 5thGens...all good...

6th Gens should be monsters!

The important thing to think about when looking at the weight of a Z/28 vs an SS is not really what the actual numbers are but where that weight is. On the Z/28 they took a bunch of un-sprung weight out of the wheels & tires. That makes the wheels more responsive to the pavement. When they thinned out the rear glass, that took out some weight that was sitting up high, thus lowering the CG.

The engine is heavier, but its a dry sump system. It sits lower, and the added weight of the reservoir sits (presumably) towards the middle of the car. Lower CG & better polar moment. I imagine that the axles are a tad stouter than the SS units, which again lowers the CG. Same thing with a beefier suspension.

Looking at the basic specs isn't enough to understand whats going on with the Z/28. You have to dig deeper. And the deeper I dig, the more impressed I get. It all fits with a single mindedness, a single purpose. This is a car build to do one thing, and do it awesomely. And that one thing is "To beat the shit out of anything Ford can out on the road"
