Buriram WTCC: Jose Maria Lopez wins race and 2015 championship

Lopez led from pole position and his title triumph was sealed when rival Yvan Muller was involved in a messy opening lap behind the Argentinian.

First, contact at Turn 1 left three yellow cars parked in the run-off area, with the Chevrolet of Tom Coronel and Ladas of Nicky Catsburg and Nicolas Lapierre all eliminated.

Muller was caught up in a melee at Turn 6 together with fellow Frenchman Hugo Valente, and was forced to retire to the pits with damage.

After the subsequent safety car period, Lopez was forced to defend at the restart from Sebastien Loeb.

As the race wore on, Lopez gradually shook off the nine-time World Rally champion, finishing 1.3 seconds clear as he claimed his ninth win of the season.

Ma Qing Hua passed Mehdi Bennani at the restart and kept the Moroccan at bay to complete the podium in a Citroen 1-2-3-4.

The attrition continued after the first lap, with Tom Chilton slowing out of fifth place 10 laps in, while John Filippi and Tiago Monteiro had already come to blows behind the Briton.

Inheriting fifth was therefore Gabriele Tarquini, up from 15th on the grid, ahead of Rob Huff, who started 18th and last on the grid after his rear windows were found to be not thick enough in qualifying.

The British Lada driver passed a battered and bruised Monteiro, who ended up seventh ahead of Stefano D'Aste and Gregoire Demoustier.

Local entrant Tin Sritrai picked up 10th on his debut as the final finisher.
