I can't say for sure, but my notes say that I weighed our competition chassis (0.06" sheet AL) at 8lbs, before we started assembling any of the components on to it.
Weight is a factor in our decision to use this type of drivetrain...but, it's probably #3 on the list. #1 would be resources available (in-shop waterjet) and ease of construction (no welding) and #2 would be robustness.
Our design is a nightmare for ease of maintenance. Changing wheels or drivetrain components is not something we could do easily/quickly.
