The Cayenne S Titanium Edition was designed specifically for the U.S. and Canadian markets. Introduced only for 2006 (as a pre-GTS concept), it was a 1 year exclusive, limited production SUV featuring a lightweight steel body, aluminium hood, titanium-painted accented body parts, side lower rocker body panels, Sport-Quad Tip Exhaust chrome tailpipes, 19" titanium painted alloy wheels, bi-xenon headlights, two-tone interior upholstery, Porsche PCM 2.0 w/ trip computer navigation, MP3 audio and Bose cabin surround sound.
Porsche made things more interesting with the launch of a Turbo S version in 2006 to compete with the Mercedes-Benz ML 63 AMG. The Turbo S is powered by a twin-turbocharged 4.5 L V8 that produces 521 PS (383 kW; 514 hp) and 720 N⋅m (530 lb⋅ft) of torque; Acceleration from 0–60 mph (97 km/h) takes 5.0 seconds and the top speed is 171 mph (275 km/h); It features a six-speed automatic Tiptronic transmission.
The first-generation Cayenne was what saved Porsche. The based Porsche Cayenne 955 entered the market to a mixed reception, although it was the performance vehicle among SUVs and had comparably good handling as well as powerful engines. The lineup initially consisted of the V8-powered Cayenne S and Cayenne Turbo. Later in the model cycle, VR6 and diesel-powered versions joined the lineup. The base model is powered by a VW 3.2-L VR6 engine producing 250 PS (184 kW; 247 hp). The engine is largely the same as the VW engine.
The first-generation Cayenne saw the introduction of the Cayenne S in 2002. While the base Cayenne had a 3.2-L VR6 engine, the Cayenne S got a 4.5 L V8 with more power and torque. The extremely short and compact normal-aspirated V8 produced 340 hp and 310 lb⋅ft of torque. Acceleration for the Cayenne S is strong for an SUV, with 0–60 mph taking 6.9 seconds and the top speed being 150 mph. The Cayenne S also have some visual changes to better identify it, but was otherwise standard Cayenne fair.
The first-generation Cayenne Turbo 955 has 450 PS (331 kW), and can accelerate from 0–100 km/h (62 mph) in 5.3 seconds. Under the hood, the Cayenne Turbo was fitted with a turbocharged 4.5-liter V8 unit mated to a standard 6-speed automatic. Thanks to the standard air-suspension, the Turbo version could get up to 28 cm (11”) of ground clearance. The German brand needed a car to sell in volumes and save them from a foreseeable financial collapse. The Cayenne Turbo did just that.
