"Cadillac claims a less than 3,400-pound curb weight on the ATS will be one of the lowest in the segment along with nearly 50/50 weight balance."
EDIT: The weight is true
"All-new, lightweight, rear-wheel-drive architecture with one of the lowest curb weights in the segment – less than 3,400 pounds"
