Lewis Hamilton has called for changes to be made to Formula One's technical rules in a bid to spice up the show.

Hamilton, the newly-crowned triple world champion, rued a "boring" Brazilian Grand Prix after he followed Nico Rosberg home for the second time in as many races.

The 30-year-old Briton knew his best chance of beating pole-sitter Rosberg would be on the short run down to Turn One.

"I could not get close enough to be able to put on a great race so it was relatively boring"

And while the pair came narrowly close to touching wheels, as they did in Austin last month, Rosberg retained the inside line before controlling the race and sauntering to victory.

Hamilton's subsequent plea to his team for a different strategy to that of Rosberg was denied and, as such, a rather processional race ensued.

Hamilton insisted he had the outright pace to win in Brazil, but claimed the mechanical make-up of a modern grand prix car makes overtaking impossible.

"At the end of the day it doesn't really matter what we say because it can't happen," said Hamilton when asked if it was time for a fundamental change to the sport's technical rules.

"The big bosses make the decisions and whether or not they make the right ones for many years, who knows?

"Something has got to change. Some races you can follow which enables you to have good racing, but otherwise there are some places where you can't.

"I guess for the fans it is probably not too exciting to watch. It is always nice when you're at the front - as we have been for some time now - but still being able to race is what fans want to see.

"I could not get close enough to be able to put on a great race so it was relatively boring."

Hamilton has long been an advocate of closer racing, but Rosberg, who claimed his fifth victory of the season in Interlagos, said an overhaul of Formula One's technical rulebook would not have affected the outcome of Sunday's race.

"Up front I had the pace advantage over Lewis so of course he is not going to come by me because at the end of the race I was six seconds in front," Rosberg said.

Hamilton had a sniff at passing Rosberg when the German missed the apex at Turn One midway through this penultimate race of the season - but that was largely as good as it got for the world champion.

Hamilton added: "Contrary to what Nico was saying, at one point I was all over him, but inside one second, I just couldn't get by."
