German-tuning firm Hofele-Design has released program details for the 2010 Porsche Cayenne 958 in preparation for the Essen Motor Show 2011. Dubbed the Hofele Cayster GT 670, performance has been increased from 245 to 315hp and 405 to 479lb-ft of torque on the 3.0-liter TDI V6, and from 380 to 481hp and 428 to 544lb-ft of torque on the Cayenne S Hybrid. A twelve-piece aerodynamics kit features front end attachments with openings for the original fog lamps, wheel arch extensions and a rear apron diffuser.

Four-tube stainless steel tailpipes are fitted to the improved rear apron, but the original Cayenne tailpipes can also be accommodated. Carbon mesh inserts are available for the original Turbo front bumper, and the new sports bonnet features carbon-fiber air intakes. The SUV can sit on 20- or 22-inch designer alloys, and an electric lowering module lowers the Cayenne by up to 40mm while stationery or up to 50mph. The interior features a two-tone StarLight leather with nested stripes, leather crest inserts and offset decorative stitching. Carbon panels are offered for the console, dashboard and doors.
