The Porsche 911, internally type 993, is the fourth generation of the 911 model of Porsche sports car, manufactured and sold between 1994 and 1998 (model years 1995–1998 in the United States), replacing the 911, type 964. Its discontinuation marked the end of air-cooled 911 models. The 993 was much improved over and quite different from its predecessor. According to Porsche, "every part of the car was designed from the ground up, including the engine" but nevertheless "only 20% of its parts were carried over from the prior 911". Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective." The external design of the Porsche 993 was penned by English designer Tony Hatter. It retained the core cabin and body shell architecture of the 964 and prior 911 model iterations, but exterior panels were revised with much more flared wheel arches, a smoother front and rear bumper design, an enlarged retractable rear wing, and teardrop shaped mirrors. Porsche engineered a new light-alloy rear subframe with an entirely new multi-link coil springs and wishbone rear suspension design, dubbed the Weissach axle – making significant progress with the engine's impact on the car's handling, putting behind the previous lift-off oversteer and providing an improved driving experience and creating a more civilized car overall. The 993 had several variants, like its predecessors, varying in body style, engines, drivetrains, and included equipment. Engine power was increased by the addition of the VarioRam system, that added particularly in the mid-range of rpms, and also resulted in more throttle-noise at higher revs. The VarioRam system resulted in a 15 percent increase in the new 911's engine power over its predecessor. The 993's available all-wheel drive system replaced the 964's centre differential with a viscous coupling, similar to...
