Jerez, Spain - The new rules for deciding this season's Formula One drivers' title ratified by FIA earlier this week have been met with criticism by some of the sport's top names, including defending world champion Lewis Hamilton.

"I don't really like it," the McLaren-Mercedes driver was quoted by Thursday's Bild newspaper as saying while two-time world champion Fernando Alonso also expressed his unease at the new points system where the driver with the most wins takes the title.

Jerez, Spain - Red Bull officially unveiled its car for the 2009 Formula One season Monday at the Spanish Jerez circuit.

The new RB5 car, which was presented by Red Bull drivers Mark Webber and Sebastian Vettel, is powered by a Renault engine designed by Adrian Newey and encompasses the far-reaching regulation changes that have been brought in to cut costs for the 2009 season.

"The team is well prepared to profit from the rule changes," said team principal Christian Horner, who is hoping Vettel can repeat his feat of last year at the Italian Grand Prix while still at Toro Rosso by securing Red Bull's maiden F1 win.
