Rinspeed of Switzerland have designed the X-treme to markedly differentiate itself from Porsche's Cayenne, putting dynamism and a distinctive character at the forefront of its brief. Larger front air intakes, with fins and front splitter, air fatter brakes and a higher-output 600 hp engine. The gaping front, much like beefier wheel arches, gives the impression of a wider, more dynamic vehicle, while a 35mm lowered ride height brings with it a more poised stance.
The side skirt elegantly and unobtrusively integrates into the body and its larger arches, while understated but equally dynamic skirts at the front and rear contribute to the car's aerodynamics. An aggressive note sounds from the X-treme's sporty exhaust system, stylised by quad chrome exhaust tips. Excellent road-holding is ensured by use of large 23-inch wheels and 315/25-23 tires capable of speeds of up to 300 kph.
Customising the cabin are a range of exclusive leather trim options, with bucket seating and an in-car entertainment system among the items specifiable.
