993 (1995-1998) the last air-cooled 911
This is Far Better than Porsche ever made the Turbo look - its on STEROIDS !
The Porsche 993 is the 4th generation of the Porsche 911 model sports car manufactured and sold between January 1994 and early 1998 (model years 1995-1998 in the United States), replacing the 964.
It's 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 and only 20% of its parts were carried over from the previous generation.
Porsche refers to the 993 as "a significant advance, not just from a technical, but also a visual perspective."
Porsche's engineers devised a new light-alloy subframe with coil and wishbone suspension (an all new multi-link system, Weissach axle), putting behind the previous lift-off oversteer
and making significant progress with the engine and handling, creating a more civilized car overall and providing an improved driving experience.
The 993 was also the first 911 to receive a six speed transmission.
The 993 had several variants, as its predecessors, varying in body style, engines, drivetrains, and included equipment.
Power was increased by the addition of the VarioRam system, particularly in the midranges, and also resulted in more throttle noise at higher revolutions; as a consequence, it resulted in a 15 percent increase in power over its predecessor.
The external design of the Porsche 993 was penned by English designer Tony Hatter and retained the basic body shell architecture of the 964 and other earlier 911 models, but with revised exterior panels with much more flared wheel arches, a smoother front and rear bumper design, an enlarged retractable rear wing, and teardrop mirrors.
A 993 GT2 was used as the safety car during the 1995 Formula One season.
The 993 was the first generation of the 911 to have a six-speed manual transmission included as standard; its predecessors had 4 or 5 speed transmissions. In virtually every situation, keeping the engine at its best torque range above 4,500 rpm was possible.
The Carrera, Carrera S, Cabriolet, and Targa models (rear-wheel drive) were available with a "Tiptronic" four-speed automatic transmission, first introduced in the 964. From the 1995 model year, Porsche offered the Tiptronic S with additional steering wheel-mounted controls and refined software for smoother, quicker shifts. Since the 993's introduction, the Tiptronic is capable of recognising climbs and descents.
The Tiptronic-equipped cars suffer as compared to the manual transmission equipped cars in both acceleration and also top speed, but the differences are not much notable
Tiptronic cars also suffered a 55 lb (25 kg) increase in weight.
The 993's optional all-wheel drive system was refined over that of the 964.
Porsche departed from the 964's setup consisting of 3 differentials and revised the system based on the layout from its 959 flagship, replacing the centre differential with a viscous coupling unit.
In conjunction with the 993's redesigned suspension, this system improved handling characteristics in inclement weather and still retained the stability offered by all-wheel drive without having to suffer as many compromises as the previous all-wheel drive system. Its simpler layout also reduced weight, though the four-wheel drive Carrera 4 weighs 111 lb (50 kg) more than its rear-wheel drive counterpart at 3,131 lb (1,420 kg) vs. 3,020 lb (1,370 kg).
