Grapevine: Rankings: Johnson continues slide

Having won the autumn race at the North Carolina speedway last year, the four-time champion needed a repeat result to maintain his Castrol Rankings score.

As he could only manage third though, the Hendrick Chevrolet driver fell behind IndyCar runner-up Will Power and now lies seventh - four places lower than where he was in March.

Jamie McMurray's win at Charlotte promoted the Earnhardt Ganassi Chevrolet driver three places to 24th while his team-mate Juan Pablo Montoya (34) enjoyed another strong run and climbed four spots.

Title contenders Tony Stewart (25) and Kurt Busch (22) both suffered via spins while Joe Gibbs Toyota drivers Kyle Busch (12) and Denny Hamlin (11) retained their Castrol Rankings positions by finishing second and fourth.

Britain's Paul di Resta seized the lead of the DTM by taking his third win in a row at Hockenheim. The AMG Mercedes driver also climbed two spots in the Castrol Rankings to 43rd, and is now the highest-ranked DTM driver.

His Canadian team-mate Bruno Spengler, 44th last week, triggered an opening-lap pile-up and retired himself soon after. He dropped eight spots in the Castrol Rankings to 52nd to leave himself only four places ahead of Mike Rockenfeller, a podium finisher for Audi.

Juho Hanninen was already more or less assured of the Intercontinental Rally Challenge title before last weekend's Rally Scotland, but his Skoda team-mate Jan Kopecky's (112) non-participation made certain of the crown.

Despite nothing being at stake, the Finn won the event and gained 12 places. Hanninen, who now lies 45th, is ranked higher than any IRC regular has ever been before.

Heading the other way were Peugeot's Kris Meeke (147), who replaced his maximum score from last year's Sanremo Rally with a third place in Scotland and dropped 24 spots, and Skoda's Guy Wilks (182), who fell 17 places.

He was not the biggest mover in the top 100 though. That honour went to F3 Euro Series champion Edoardo Mortara (75), who won the penultimate race of the season at Hockenheim in his Signature Dallara and gained 16 places.

Jules Bianchi (67), whom Mortara succeeded as champion, was the biggest faller. The GP2 racer was not in action last weekend, but still lost the scores he gained from the 2009 Euro Series finale. As a result the Frenchman lost 15 places.
