Porsche 944
The Porsche 944 was a sports car built by Porsche from 1982 to 1991. It was built on the same platform as the 924, although 924 production continued through 1988. The 944 was intended to last into the 1990s, but major revisions planned for a 944 S3 model were eventually rolled into the 968 instead, which replaced the 944. The 944 was a successful model and was available as both a coupe and cabriolet in naturally aspirated and turbocharged forms.
Porsche made a new all-alloy 2.5 litre straight-4 engine, a four cylinder engine was chosen for fuel efficiency and size, because it had to be fitted from below on the Neckarsulm production line. To overcome the unbalanced secondary forces that make other four cylinder engines feel harsh, Porsche included two counter rotating balance shafts running at twice engine speed. balance shafts carry eccentric weights which produce inertial forces that balance out the unbalanced secondary forces, making a four cylinder engine feel as smooth as a six cylinder. The engine was factory-rated at 150 hp. in its U.S. configuration. Revised bodywork with wider wheel arches. Porsche introduced the 944 for 1982 to great anticipation. In addition to being slightly faster, the 944 was better equipped and more refined than the 924, it had better handling and stopping power and was more comfortable to drive. 0-60 mph time 8.3 seconds with a top speed of 130 mph The car had nearly even front to rear weight distribution (50.7% front/49.3% rear)
In 1986 Porsche introduced the 944 Turbo, that produced 220 hp at 6000 rpm. The turbo was the world's first car using a ceramic portliner to retain exhaust gas temperature.
The 1987 model year, the 944 was updated to incorporate Anti-lock braking and airbags for increased safety. In early 1989 before the release of the 944S2, Porsche upgraded the 944 from the 2.5 liter engine to a 2.7 liter engine rated 162 hp the new engine featured a siamesed-cylinder block design and a different cylinder head which incorporated larger valves.The 944S featured a normally aspirated, dual overhead cam 16 valves 189 hp version of the 2.5 litre engine. This marked the first use of four valves per cylinder in the 944 series. Performance was quoted as 0 – 60 mph in 7.6 seconds 140 mph top speed. (non-TURBO)
In 1988, Porsche introduced the Turbo S option package. The 944 Turbo S had a more powerful engine with 247 hp 260 lb·ft torque the standard 944 Turbo 217 hp and 243 lb·ft. In June 1988, Car and Driver tested the 944 Turbo S a 0-60 mph time of 5.5 seconds and a quarter mile time of 13.9 seconds at 101 mph Top speed was factory rated at 162 mph. In 1989 the 'S' designation was dropped from the 944 Turbo S, and all 944 Turbos featured the 'S' package as standard.
1989 944S2 was introduced, and powered by a 208 hp 3.0 L engine, the largest production 4 cylinder engine of its time. The 944S2 had the same rounded nose and a rear valance found on the Turbo model. This was the first example of the use of an integrated front bumper, where the fender & hood profiles would merge smoothly with the bumper...a design feature that has only now seen widespread adoption on nearly all cars. The S2 was also available as a cabriolet, a first for the 944 line. Performance was quoted as 0-60 mph in 6.6 seconds with a top speed 150 mph.
1990, Porsche engineers began working on what they had intended to be the third evolution of the 944, the S3. As they progressed with the development process, they realized that so many parts were being changed that they had produced an almost entirely new vehicle. Porsche consequently shifted development from the 944 S3 to the car that would replace the 944 entirely, the 968. The 944's final year of production was 1991; in 1992 the 968 debuted. The 968 was sold alongside the 928 through 1995, when both models were discontinued.
1991 Porsche released the 944 Turbo Cabriolet, which combined the Turbo's 250 hp engine with the cabriolet body. 625 were built 100 were right hand drive. None were imported to the U.S.
Collectibillity :The number of surviving 944s is falling due to the high maintenance costs.The post-1985 cars, Turbos, and S variants are considered more desirable than the earlier cars; having improved interiors, suspensions, and engines. The pre-1985 cars are valued due to their lighter curb weight and "no-nonsense" interior layout.
The Porsche 944 has proven to be successful and increasingly popular in amateur road course racing.The 944-Spec class caters to the 1983 to 1988 8-valve 944, and the 944 Cup series has classes for all 924/944/968 and 944 Turbo models. Competitive racing events are held by the National Auto Sport Association (NASA) and other organizations, as well as compatible rules that allow the same cars to race with theSports Car Club of America (SCCA) and Porsche Owner's Club. In total 163,192 cars in the 944 family were produced between 1982 and 1991. A total of 25,245 944 Turbos were made, with 13,982 being exported to the United States.

The Porsche Carrera GT
The Porsche Carrera GT is a mid-engined sports car. The development of the Carrera GT can be traced back to its predecessors, the 911 GT1 and LMP1-98 racing cars. Due in part to the FIA and ACO rule changes in 1998, both designs had ended. Porsche at the time had planned on a new Le Mans prototype for 1999. The car was initially intended to use a turbocharged flat-6, but was later redesigned to use a new V10 engine. The 5.5 L V10 from the prototype in a concept car shown at the 2000 Geneva Motor Show, in an attempt to draw attention to their display. Surprising interest in the vehicle and an influx of revenue provided from the Cayenne helped Porsche decide to produce the car, and development started on a road-legal version that would be produced in small numbers at Porsche's new manufacturing facility. Porsche started a production run of Carrera GTs in 2004, shipping the units with an MSRP of $440,000 The first Carrera GT went on sale in the US on January 31, 2004.
Originally a production run of 1,500 cars was planned. But Porsche announced in August, 2005 that it would not continue production of the Carrera GT through 2006, citing discontinuation was due to changing airbag regulations in the US. The Carrera GT is powered by a 5.7 V10 producing 612 hp 435 lb-ft of Torque. 0 to 60 mph in 3.6 seconds 0 to 100 mph 7.3 Top Speed 205 mph and runs the 1/4 mile in 11.1 seconds @ 133.4 mph.

Porsche recalling 1,700 911's
- Porsche is recalling about 1,700 of its 911s from 2010-11 because wheel hubs may wear prematurely, resulting in a compromised wheel-retention system that could lead to a crash, the automaker told the National Highway Traffic Safety Administration. Porsche said the 911 Turbo, 911 Turbo S, the 911 GT3 and GT3 RS, and the GT2 RS equipped with the center locking wheel and hub assembly were affected. Dan Engelman, a spokesman for Porsche Cars North America, said he was unaware of any accidents relating to the condition.
