Porsche 968
The Porsche 968 is a sports car manufactured by German automobile manufacturer Porsche AG from 1991 until 1995. It was the final evolution of a series of water-cooled front-engine rear wheel drive models begun almost 20 years earlier with the 924, taking over the entry-level position in the company lineup from the 944 with which it shared about 20% of its parts. The 968 was Porsche's last new front-engined vehicle before the introduction of the Cayenne SUV in 2003. History Porsche's 944 model debuted for the 1982 model year as an evolution of the 924, was updated as "944S" in 1987 and as "944S2" in 1989. Porsche was in significant financial crisis at the time with less interest in its sports cars from customers, especially in the US. The virtually unchanged design of the 944, which was derived from the 924, was showing its age and sales of the model declined. Porsche hence found the need to develop a new entry level model. Shortly after the start of production of the S2 varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front-engine
In automotive design, a front-engine, front-wheel-drive (FWD) layout, or FF layout, places both the internal combustion engine and driven roadwheels at the front of the vehicle. Usage implications Historically, this designation was used regardless of whether the entire engine was behind the front axle line. In recent times, the manufacturers of some cars have added to the designation with the term '' front-mid'' which describes a car in which the engine is in front of the passenger compartment but behind the front axle. The engine positions of most pre– World-War-II cars are ''front-mid'' or on the front axle. This layout is the most traditional form and remains a popular, practical design. The engine, which takes up a great deal of space, is packaged in a location passengers and luggage typically would not use. The main deficit is weight distribution—the heaviest component is at one end of the vehicle. Car handling is not ideal, but usually predictable. In contrast wit ...

Variable Valve Timing
In internal combustion engines, variable valve timing (VVT) is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions. It is increasingly being used in combination with variable valve lift systems. There are many ways in which this can be achieved, ranging from mechanical devices to electro-hydraulic and camless systems. Increasingly strict emissions regulations are causing many automotive manufacturers to use VVT systems. Two-stroke engines use a power valve system to get similar results to VVT. Background theory The valves within an internal combustion engine are used to control the flow of the intake and exhaust gases into and out of the combustion chamber. The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing or variable valve lift, the valve timing is the same for all engine speeds and conditions, therefore compromises are neces ...

VarioCam
VarioCam is an automobile variable valve timing technology developed by Porsche. VarioCam varies the timing of the intake valves by adjusting the tension on the timing chain connecting the intake and exhaust camshafts. VarioCam was first used on the 1992 3.0 L engine in the Porsche 968. Porsche's more recent VarioCam Plus combines variable valve timing with two-stage lift on the intake side. The two-stage valve-lift function is performed by electro-hydraulically operated switchable tappets. Each of these 12 tappets consists of concentric lifters which can be locked together by means of a pin. The inner lifter is actuated by a small cam lobe, while the outer ring element is moved by a pair of larger-profile lobes. The timing of each valve is seamlessly adjusted by means of an electro-hydraulically operated rotary vane adjuster at the head of each intake camshaft. Valve timing and the valve profile are continuously altered according to conditions and engine load. For improved r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Porsche 993
The Porsche 993 is the internal designation for the Porsche 911 model manufactured and sold between January 1994 and early 1998 (model years 1995–1998 in the United States), replacing the 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 engineAutoTraderClassics.com — Article Finding Porsche's best road car — Porsche 911S vs 993. 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 ca ...

Porsche 928
The Porsche 928 is a luxury grand tourer produced by Porsche AG of Germany from 1978 until 1995. Originally intended to replace the company's iconic 911, the 928 combined the power, poise, and handling of a sports car with the refinement, comfort, and equipment of a luxury sedan. The 928 became the top-of-the-line production car sold by Porsche. Porsche executives believed such a flagship would have wider appeal than the compact 911. The 928 has the distinction of being the company's first production V8-powered model and its only coupé powered by a front-mounted V8 engine. Conception By the late 1960s, Porsche had firmly established itself as a manufacturer of high-performance sports cars. In the wake of the 1970s oil crisis, executives, including owner Ferdinand Porsche, were beginning to consider adding a more fuel-efficient luxury touring car to the line-up. Managing director Ernst Fuhrmann was pressuring Ferdinand to approve development of the new model due to concerns th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
