Curb Weight

What are the Curb weights of the F12, 599 GTO, 599 GTB??

I see many different weights listed.

I understand the options will make some differences, Ceramic carbon brakes on the GTB, wheels, etc. but they seem to vary wildly.

F12 CURB WEIGHT (F/R DIST) 4003 lb (47/53%) Curb weight1,630 kg (3,594 lb) [3] Ferrari calls the curb weight 3593.5 lb, and says so without a smile or a wink. Though we’ve found that Ferrari’s scales are liberal



599 GTO 3538 lbs Curb weight: 3850 lb

599 GTB Curb weight1,688 kg (3,721 lb)

 

There seems to be no standardization though good auto magazines define the conditions for weight, e.g., full tank of fuel, 170 lb driver, etc., so that you can trust their relative weight results for different cars.
