Why is the z06 vette lighter than the base C6 and ZR1 models? The Z06 has the biggest engine but still weighs in at almost 200 pounds lighter than a zr1.
3333lbs vs 3175lbs

The 7.0L LS7 uses the same aluminum engine as all other Corvettes, but with a larger bore and longer stroke to increase displacement. So the engine doesn't weigh any more than any other LSx engine.

The big weight savings come from the carbon fiber body panels and aluminum frame rails used on the Z06. The ZR-1 also uses these weight saving techniques, but weighs more due to the supercharger and it's supporting hardware. The base C6 and Grandsport use steel frame rails and composite panels and weigh in around 3200-3300lbs.

The C-5 ZO6 also has a thinner windshield among other weight savings. I'm sure one could do a search and find a total list

I should note that the information I mentioned was specific to the C6 Z06. Since he was mentioning the bigger engine and C6 variants I didn't go into the C5 Z06 or any of the differences between C5 variants.

my 03 z06 weighed in at just under 3k with a half a tank of gas in it.

The ZR1 also has a supercharger, that plus the intercooler and piping can easily add over 100 pounds to a vehicle.

The 05 c6 Z-51 vette weighed only 3185...the lowest weight of all c6 base vettes. DON'T BELIEVE ME DO YOUR RESEARCH !!!!!

dont forget larger rims and brakes tires and magnetic ride which help add weight , i think i read the biggest factors of the zr1 weight is the engine and the magnetic ride .

This thread has some fail info in it.


LS7 weighs less than other LS motors because it uses a LOT of titanium parts. The weight savings isn't enough to make a huge difference though. And LS7 Corvettes come with a dry sump system which more than out-weighs the engine weight savings. However, the C6Z is the lightest of the C6s. It's about 80Lbs heavier than a C5Z but packs approx 90RWHP more. Power to weight ratio is better for the C6Z.

BTW, the physical size of the LS7 is approximately the same as the LS1/2/3/6. The displacement of an LS motor doesn't make it physically bigger or heavier. Just because it's 7 liters doesn't mean it's physically larger than a 4.8 LM7 (for example). Where one motor fits, the other will fit too.

The supercharger on the LS9 adds a significant amount of weight to the motor. It also makes it physically larger. The block, however, is the same physical size regardless of it being a 6.2L motor. It's the intake/blower/intercooler that is so much larger.

Officially, the C6 Z06 weighs 3180Lbs. Officially from GM, my C5Z weighs 3112Lbs. However, after weighing my car, it came out to 3080Lbs with 1/2 tank of gas. I'm sure the race weight on the C6 Z06 is closer to 3100Lbs.

BTW, my 02 Z06 with HRE wheels (at stock sizes) weighed 3070 with 1/2 tank of gas. It's not a fluke.

My 05 m6 came in at 3180 also

Do you recall how much fuel you had?

Mine was just weighed in at 3118 with the big *** blower up front. 1/2 tank of fuel.

No, the single biggest factor is the supercharger. The engines themselves are very similar in weight. The magnetic ride shocks don't weigh in at 25lbs a piece and the ZR1 wheels, tires and ceramic rotors are pretty light.

As almost every other car in the world over the last several decades has become heavier, the Corvette has gotten lighter! I can remember when car magazines in the '70's, '80's and '90's use to complain that the Corvette was too heavy, as other cars in it's class were lighter. Now it is the other way around, but it seems the weight issue isn't ever mentioned anymore. Bob

Of course not. When the Corvette weighs less than it's exotic European competitors it's time for magazines to focus on other things. For example, Car and Drivers: Best Handling Car Under $100k article. The take away is that handling is defined as the car with the best seats and steering feel. That article was such a failure of journalism that at this point I wouldn't read C&D if it was free. If they had titled the article "The Best Sports Car Under $100k" it would have at least been somewhat tolerable. Oh well the driver of the winning Porsche can wave the magazine at the GTR's and Z06's as they quickly pass him. And do it from a very good seat with nicely weighted steering.
