Honda's Gabriele Tarquini took a dominant lights to flag victory in the Feature Race at Oulton Park as Anthony Reid further increased his lead over title rival Alain Menu.
Gabriele Tarquini left the rest of the BTCC field battling in his wake as he stormed to his third win of the year, leading almost every lap as he strolled to victory.
The top two positions from the earlier Sprint Race were reversed as Anthony Reid followed the Honda home to increase his lead over Alain Menu to nine points heading into the last round at Silverstone.
As in the first race of the day, the main excitement surrounded the fight for the lower positions with the scrap fro third place remaining unresolved until long after the pit stops.
James Thompson initially held the place from Menu, Yvan Muller and Rickard Rydell although lightning quick stops from Menu and Jason Plato put them in third and fourth places respectively with Muller, Vincent Radermecker, Thompson, Tom Kristensen and Rydell all closely following.
Last men to pit were Matt Neal and Reid but while Neal was trapped at the back of the Super Touring, Reid was easily able to retain his second place even though Menu was now right behind the Championship leader.
However Menu's weight disadvantage soon took its toll and the Swiss driver fell back to sixth at the flag behind an inspired Muller, Plato and a hardworking Thompson who gave himself a mountain to climb after pitting too early.
Tarquini's comfortable six second advantage was erased on lap 17 when Kristensen suffered a scary accident at the high speed Druids corner, the right front brake disc exploding and ripping the bodywork and tyre to shreds. The Danish driver was able to guide his Honda backwards into the tyre barrier meaning that personal damage was minimal although he was visibly shaken after the crash.
The dangerously placed Accord required another appearance from the safety car but while the field was bunched up once more, Tarquini's win was never in doubt and in the remaining ten laps after the safety car disappeared, the Italian opened up a comfortable three-second cushion over Reid.
