Lewis Hamilton has launched another attack on the latest rule changes in Formula 1.

Earlier this week, the reigning triple world champion said that moves to make the cars wider but also heavier in 2017 are "ridiculous".

Now, the Mercedes driver has ridiculed the decision to crown a 'driver of the day' after each grand prix.

At Tuesday's meeting of the F1 Commission, it was decided that TV viewers would vote for the best driver during the telecast and then see him "presented with their prize" at the finish.

"Driver of the day doesn't sound good to me," The Sun quotes Hamilton as saying.

"It sounds like a pointless exercise. I don't really have positive things to say about it."

He also hit out at the revamped 'musical chairs' format for qualifying, saying that it would be "a waste of time" to stage a dressed rehearsal prior to Melbourne.

"I don't think it is going to make any difference," he said.

"I just don't think it's going to add to the spectacle for the fans, and that's really what we've got to do."

The Melbourne Grand Prix takes place on March 20.
