While Porsche is passionately regarded as a leading name in sports car production, the company officially adds a supercar to their product line for 2004. Exhibiting Porsche's most advanced engineering and technologies, the limited production Carrera GT employs optimized aerodynamics and the extensive use of carbon fiber in its construction. Literally at the center of the Porsche Carrera GT, a 5.7-liter V-10 engine generates 605 horsepower allowing the supercar to achieve velocities of 205 miles per hour. All-new the ever-expanding Porsche 911 range, the GT3 embodies the engineering meant to harness maximum performance on a race track in the guise of a production-based sports car. Incorporating similar focus to weight reduction as the GT2, the 2004 Porsche 911 GT3 is powered by a naturally-aspirated flat-6 engine. A new Porsche 911 Carrera 4S Cabriolet has been introduced as a companion to the already-offered Carrera 4S coupe. Providing greater range for the Cayenne sport utility, a six-cylinder model newly offered. Porsche celebrates two milestones in 2004 with a special 40th Anniversary 911 and Special Edition Boxster S serving as a 50th anniversary tribute to the 550 Spyder.
