The Porsche 944 was a luxury sports car built by Porsche from 1982 to 1991 it was built on the same platform as the 924 which remained in production until 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 cooper copyright and Cabriolet in naturally aspirated and turbocharged forms history and model overview the porsche 924 had originally been a project of VW porsche joint porsche volkswagen company created to develop and produce the 914 which was sold in europe as both apportioned of volkswagen in 1972 a replacement for the volkswagen version of the 914 codename da 425 began development the model was to be sold as an Audi as part of the VW audi porsche marketing arrangement although testing had begun in the spring of nineteen seventy-four Volkswagen decided to cancel the program due to the expense of production as well as the feeling that the recently released Volkswagen Scirocco would fill the sports coupe a sufficiently at the time Porsche was considering introducing their own water cooled front engine 2+2 coupe a to replace the 912 II and their model of 914 and Volkswagens cancellation provided an opportunity Porsche purchased the design and the finished development with an mechanical fuel injection system the vehicle drove and handled exceptionally well and received positive reviews but was criticized for the Audi source 2-liter engine later in 1979 porsche introduced a turbocharged 924 to increase performance but the price was considered too high for the time which hampered sales rather than scrapped the design Porsche decided to develop the 924 as they had with generations of the 911 although model numbers would change the 924 would provide the basis for its replacement porsche reworked the platform and abandoned the audi engine installing in its place its own freshly designed all alloy 2.5 liter straight-4 engine bore 100 mm stroke 78.9 mm that was in essence half of the 928 s 5.0 litre v8 although very few parts were actually interchangeable not a natural choice for a luxury sports car a four-cylinder engine was chosen for fuel efficiency in size because it had to be fitted from below on the Newcastle 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 invented in 1904 by british engineer frederick lanchester and further developed and patented in 1975 by Mitsubishi Motors 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 body work with wider wheel arches similar to that of the 924 Carrera GT a fresh interior and upgrades to the braking and suspension systems rounded out the major changes porsche introduced the 944 for my 1982 to great anticipation in addition to being slightly faster the 944 was better equipped and more refined than the 924 s it had better handling and stopping power and was more comfortable to drive the factory claimed 0 60 mile per hour time of less than 9 seconds the factory claimed top speed of 130 mile per hour was also pessimistic autocar having verified a top speed of 137 a mile per hour the car had nearly even front to rear weight distribution thanks to the rear transaxle balancing out the engine in the front this gave it very balanced predictable handling at the limits of adhesion in mid nineteen eighty-five the 944 underwent its first significant changes these included awah new dash and door panels embedded radio antennae upgraded alternator increased oil sump capacity new front and rear cast alloy control arms and semi trailing arms larger fuel tank optional heated and powered seats Porsche hi-fi sound system and revisions in the mounting of the transaxle to reduce noise and vibration the cookie-cutter style wheels used in the early 944 s were upgraded to new phone dial style wheels 1985 model year cars incorporating these changes are sometimes referred to as 1985b 85.5 or 1985 a one-half cars for the 1987 model year the 944 motronic DME was updated and newly incorporated anti-lock braking and airbags for increased safety because of the ABS system the wheel offset changed to 52 mm and fuchs wheels were no longer an option in early 1989 before the release of the 944 s2 Porsche upgraded the 944 from the 2.5 litre engine to a 2.7 liter engine bore 104 mm stroke 70 8.9 mm with a rated 162 HP for the 1988 2.5 litre engine and a significant increase in torque in addition to the increase in displacement the new motor featured a siamese cylinder block design and a different cylinder head which incorporated larger valves 944 turbo for the 1985 model year porsche introduced the 944 turbo known internally as the 951 this had a turbocharged and intercooled version of the standard car's engine that produced 220 PS in the u.s. at 6000 RPM in 1987 Car and Driver tested the 944 turbo and achieved a 0-60 mph / our time of 5.9 seconds the turbo was the world's first car using a ceramic port liner to retain exhaust gas temperature and new forged pistons and was also the first vehicle to produce identical power output with or without a catalytic converter the turbo also featured several other changes such as improved aerodynamics notably an integrated front bumper this featured the widest turn signals fitted to any production car a strengthened gearbox with a different final drive ratio standard external oil coolers for both the engine and transmission standard 16-inch wheels and a slightly stiffer suspension to handle the extra weight the turbos front and rear brakes were
