2014 British Touring Car champion Colin Turkington has already fired a warning shot for the rest of the field next year by saying he and WSR will aim to increase in strength.

The West Surrey Racing driver sealed his second career BTCC title during the first of race of Sunday's Brands Hatch finale after following the MG-duo in third position amid a crash strewn encounter.

That was as good as it got for Turkington however, as a race two tangle with Triple Eight's Jason Plato -sending the BMW into the tyres and out Paddock Hill bend - before falling off the circuit during the apocalyptic conditions in the season's final act meant the eBay Motors driver didn't score another point.

With the title already safely under wraps, Turkington admitted a chaotic end to his campaign didn't take any of the shine off his first championship since 2009.

"It was hard to get the head back into racing after winning it in race one," Turkington admitted to crash.net.

"Things were going well obviously in race two but I didn't get to the finish but a great season nonetheless, it wasn't going to take the shine off a fantastic day."

Turkington has already set his sights on defending his crown in 2015 and says he and his WSR squad must continue to improve despite the combinations relentless assault during the 2014 BTCC campaign.

His eBay Motors BMW 1 Series machine powered the 32-year old to eight victories this season but no one has successfully defended their BTCC title since Fabrizio Giovanardi done so back in 2007-08 for Vauxhall.

Turkington also added that it would be impossible to predict who will be the biggest threat to his title defence in 2015.

"Yeah you have to come back stronger," he continued. "We've put every ounce into this year and left no stone unturned to find more performance. It will be tough again next year but the 1 Series is a really great car.

"You just can't predict who's coming into 2015 with what performance. You have to say everyone will be a threat. I've given up predicting. You just have to come out of the blocks fast."
