Williams F1 cars still have too much belly fat, adding 4 & 1/2 tenths a lap.

Vowles says they trimmed 14kg - yes 14kg coming into this season
..............and they're still overweight.   

Wonder how many other bottom feeding teams are also overweight?

I find it interesting that the rules are setup in such a way that it's a challenge to achieve the minimum weight.

In the past cars carried ballast to meet weight requirements, so it's interesting that every part of the car now is crucial, and getting the weight down means making a sacrifice somewhere else... or finding a brilliant solution.

(And I do appreciate that a lot of the 'excess' weight and size of a modern F1 car is dedicated to safety features)

I think the biggest cause of today's F1 "lorries" (with a nod to Ettore Bugatti    ) is the hybrid system followed closely by fuel enough for the entire race.
