Fernando Alonso of Spain claimed the title of Formula One's season-ending Chinese Grand Prix and secured the constructors' championship for Renault here on Sunday.     

The new world champion won an incident-packed race from pole position as McLaren's championship challenge faded.

Juan Pablo Montoya was forced to retire after damaging his car on a loose drain cover while Kimi Raikkonen was held up by Giancarlo Fisichella and had to make do with second place.

Ralf Schumacher completed a season of real progress for Toyota with third place as Fisichella finished fourth to confirm Renault's world title double.

Christian Klien claimed his best result of the season for Red Bull in finishing fifth while Felipe Massa was sixth for Sauber.

Mark Webber was seventh for Williams, just ahead of BAR-Honda's Jenson Button, who scored points for the 10th race in succession with eighth. David Coulthard was ninth for Red Bull.

Seven-time world champion Michael Schumacher saw the last race of his five-year reign begin in ignominious circumstances with an accident on his way to the grid.

The Ferrari driver slowed, catching Minardi's Christijan Albersby surprise. The Dutchman ploughed into the back of Schumacher, bouncing over his rear wheel and destroying half his car. Both drivers started from the back in spare cars.
