I just found this blurb about Series 18, posted on Wikipedia. If anybody else has more info from the recent magazine article, please fill us in!!
http://en.wikipedia.org/wiki/List_of...eries_EighteenIn the January 2012 edition of Top Gear Magazine, it featured a preview of what to expect in series 18. It included a piece where Richard Hammond drives a NASCAR safety car for a real race, later going on to drive an actual NASCAR race car. The magazine also featured a part of some of the power tests to expect, including Jeremy Clarkson driving a Mercedes-Benz C63 AMG Black Edition, a Mercedes SLS AMG Roadster and a Maserati GranTurismo MC Stradale. Hammond meanwhile will drive a 2012 BMW M5 F10, and May will have a Vauxhall Corsa Nurburgring Edition. Another feature is going to China to test drive Chinese cars, Italy in 3 super-cars, Lamborghini Aventador, Noble M600 and a McLaren MP4-12C. In the pictures from the January 2012 edition of Top Gear Magazine, the presenters were standing next to a Morgan Three Wheeler, Caterham R500 and a KTM X-BOW which might have something to do with Series 18.
