Reigning world champion Lewis Hamilton has slammed Formula 1's proposed car 'revolution' for 2017.
Although the final vote has been delayed until late April, the sport's decision-making bodies this week approved a draft for wider cars and tyres and the Mercedes-devised 'halo' cockpit protection.
Mercedes's Hamilton lashed out at the hidden detail that the cars for 2017 will be even heavier than they are now - an increase from 702 to 722kg - partly because the 'halo' weighs 10 kilograms.
"I just realised that when I got to Formula 1 I think the car was 600 kilos and now it's 100 kilos heavier," Hamilton said in Barcelona.
"We don't actually have to change the regulations much to go three seconds faster, just make the cars lighter.
"They are just super-heavy. It is ridiculous if they are going to be even heavier."
The new season gets underway in Australia on March 20.
