Two-times world champion Fernando Alonso claimed his second victory of the season on Sunday when he drove to a comfortable triumph in an drama-packed Japanese Grand Prix.
The Spaniard took full advantage of incidents and errors that wrecked the day for the leading championship contenders as he steered his Renault to the 21st win of his career, two weeks after his surprise win in Singapore.
Alonso came home 5.2 seconds clear of second placed Pole Robert Kubica of BMW Sauber with Finn Kimi Raikkonen finishing third for Ferrari.
Brazilian Nelson Piquet was fourth in the second Renault ahead of Italian Jarno Trulli of Toyota and the two Toro Rossos of Frenchman Sebastien Bourdais and German Sebastian Vettel.
Drivers world championship leader Briton Lewis Hamilton failed to score a point for McLaren Mercedes after an incident-filled afternoon following a poor start from pole position.
But his main title rival Brazilian Felipe Massa of Ferrari struggled through a day of collisions, errors and penalties on his way to finishing eighth to claim a single point.
Hamilton's McLaren team-mate Finn Heikki Kovalainen retired with a blown engine.
It leaves Hamilton six points clear of Massa in the world title race with two Grand Prix left -- in China and Brazil.
