Default What does curb weight mean?

When GM publishes a curb weight does it mean the gas tank is full or empty?
Thanks!

full + both seats occupied (ave body weight). This is your GVW on the door jamb. I believe this is accurate.

There's no real convention as to curb weight, but most weigh the vehicle empty with minimal gas.

GVWR (gross vehicle weight rating) is the maximum weight allowed for the vehicle and all occupants and payload. Generally, if you subtract curb weight from the GVWR you get the maximum payload. If you do this with the Vette, you will find that GM gives the Vette a surprisingly low payload.

There are two numbers, the "curb weight" and the "GVWR" or "Gross Vehicle Weight Rating." The GVWR is the most that the car can weigh when fully loaded, but not overloaded. The C5 is only rated to hold 399 lbs. and only up to 100 lbs. of that is allowed in the trunk.

The curb weight, according the the U.S. Department of Energy, is "the manufacturer’s estimated weight of the vehicle in operational status with all standard equipment and weight of fuel at normal tank capacity, and the weight of optional equipment."

No, it depends on how many wheels are on the curb...

Thanks for all of the input. I have an Avelate Coupe conversion and I'm trying to see how it's weight compares to stock. My car weighs 3408lbs. empty. No gas, no driver, etc. Has anyone weighed theirs? Gas is 8lbs./gal. so if it actually holds 18 gal. that's 144 lbs. in case you weighed yours full of gas. Help please :confused:

Gasoline's density is about 6 pounds per gallon. Water is 8 pounds per gallon. So you can subtract nearly 40 pounds on that full tank...

Thanks for the correction. :rolleyes: Apparently I've only been making that error for 40 years now :lol: The up side is I've never crashed due to overloading the plane :cheers: The down side is my car "dry" now weighs 3416 lbs. :cry
The Florida Corvette Challenge guys know my car and I have this running argument going :smash: :smash: it is Who's Slower :thumbs:

As I pilot, I used 6 lbs/gallon too. However, I just looked it up and the gas actually weighs 5.85-6.4 lbs, depending on the type of gas...therefore, the use of 6 lbs as average. In a small plane with, say, 48 gal tanks, that could be an error of around 80-100 lbs in your weight/balance calculations ifyou used 8 lbs/gal.---and that could be a problem---especially with a fully-loaded plane. The good part is that you errored on the high side, which is better than on the low side for most circumstances. The bottomline is that you flew for 40 yrs, no doubt had fun doing so, and that's what counts.

Also, in the above post where he indicates that the C5 is rated to hold 399 lbs, he says that this only allows 100 lbs for the trunk. However, it is generally accepted that the average person weighs 170 lbs (used in the airline industry, though I see where they are planning to raise it about 10 lbs due to Americans getting fatter)---so that would only leave 59 lbs for the trunk area.
