Doc's down to 3688 (full tank of gas...lol) on his own....I'll give the boys another -100 or so and guess " 3,575 "......

A gallon of gas is around 6 lbs...full tank, over a hundred pounds right there...

I hope the Z/28 does well and I hope the price is right. I know GM usually has the best bang for buck vehicles and given the price and performance of the ZL1 I'm confident they will price the Z/28 correctly. If it does weigh under 3,700 lbs that will be awesome as a base level and then you could just add more power with a good H/C package since the Z06 has been out for over 7 years now there is plenty of track testing done on this LS7 motor. I'm guessing it comes in just under $70k with no options which is a great deal considering the Carbon Ceramic brakes which cost $8k separately.

The final number will be a lot lower and touted as an engineering accomplishment and added "wow-factor"....(as it should be)....[/

My feelings as well.
Or it's possible that someone didn't quote or write the article down exactly as he said it. Or maybe he misspoke, people do make mistakes lol.

A/C system is easy 60 lbs.

Compressor alone is 20-30lbs plus condenser, evaporator, hoses, wiring, misc.

My understanding is the "300 lbs weight reduction" already includes A/C delete and radio delete.

It was mentioned somewhere that NO AC saved 20 lbs.

It's got to be more than that. The ones I've removed have added up to a bunch of lbs. Someone in the inner circle email an engineer and ask?

Based on the poll in this forum about 2/3 of the potential Z28 buyers will pass at that price.

We can ask Number 3 in the Schno thread.

That appears to include both the AC and heating system.
