Tuner SpeedART in Germlingen, Germany (not to be confused with Leonberg-based TechArt) has unveiled its latest Porsche aftermarket upgrade package at the 2010 Essen auto show.The company's take on Porsche’s second-generation Cayenne SUV is called the Titan Evo.SpeedART’s styling upgrades for the new-shape Cayenne include redesigned bumpers front and rear (connected with lower skirts), elaborately flared wheel arches and a set of outlandishly 23" forged alloy wheels. The SpeedART Cayenne's wheels are interesting in as much they imitate Porsche's 918 Spyder hybrid in design. Beyond the ornate exterior design modifications, SpeedART’s technicians have added a set of more rebound-resistant coil springs to each wheel, with an electronic lowering module enabling more ride-height control and damper modulation. TUNED HYBRIDSpeedART's engine upgrades are available for three of the Cayenne models, two V6s (the hybrid and diesel) and headline 4.8 V8 turbo. Meticulous harmonisation of the engine control parameters combine with less restrictive air-inlet filtration and exhaust plumbing to bump power.The Cayenne hybrid’s three-litre, supercharged V6 gains 51kW (solely via tuning of the internal combustion component of its power package) to peak at 331kW. Its turbodiesel V6 sibling's peak power increases from 176 to 212kW and the range-topping Cayenne V8 turbo sees its output swell from 368 to 441kW. Rounding-off the SpeedART's treatment of the new Cayenne is a cabin customisation that includes carbon-fibre trim and fascia inserts.There is upgraded rear-seat infotainment convergence too, with the SpeedART Cayenne's entertainment screens featuring iDivice docking stations.
