The Ford Focus racer ended his season in style with two further victories at Brands Hatch last weekend to take his tally to a remarkable 12 for the season.
And, as well as cementing his championship success, those wins also enable him to jump up nine places on Autosport's winners' table to 10th spot.
While Sutton is the highest-placed improver following a busy weekend of national motorsport, he was not the only driver inside the top 10 to add to their victory total.
Both Mazda MX-5 Supercup champion Aidan Hills (at Silverstone) and Toyota MR2 Mk2 ace Dan Silvester (at Oulton Park) took a further win but these were not enough to allow them to rise from their respective sixth and seventh positions.
One driver who has improved without even racing last weekend is Junior Saloon Car star Daire Flock. A hearing into a controversial Oulton Park weekend in July resulted in him being credited with an extra 13th win of the year.
That in turn has sent him up a place to eighth on the leaderboard - and he has his mum to thank for his elevated ranking after she informed Autosport of the result change!
Further back, there was a rare defeat for Jonathan Lovell in the Porsche Boxster Cup opener at Snetterton thanks to a track-limits penalty. He did return to winning ways in race two, however, to climb three places to 13th.
Meanwhile, Jake Hill battled illness to take the last win of the BTCC season after an entertaining finale, which therefore takes him from 21st to 15th.
