procon-ten (lower case initial "p") (an acronym for Programmed Contraction-Tension) is a proprietarySafety Restraint System (SRS), used by German car manufacturer Audi from 1986 until the mid-1990s.
Audi was one of the last German manufacturers to employ airbags in their cars, mainly due to the high reliability and cost-effectiveness of the technology they trademarked as "procon-ten".
The procon-ten system used thick cables, similar to winch cables, running around the rear of the engine, and linked to it. In the event of a frontal impact, the force and momentum of the impact would shift the engine rearwards, tensioning and 'pulling' the cables, which were in turn connected to the steering column and seat belt mounts. When the cable was pulled tight by the engine, the cables would pull the steering wheel towards the front of the car, clear of the driver, and also remove any slack in the seat belts, holding the occupants more firmly in their seats until the accident had finished.
Audi engines were by tradition mounted longitudinally, in front of the front wheels, as opposed to transverse engine configuration. This meant the engine was close to the front bumper, (especially on 5 cylinder variants) that the radiator often had to be offset to halfway down one side of the engine bay. One advantage of this technique is that the engine is one of the first things to be struck in a frontal impact, taking much of the force, and allowing for high responsiveness of the procon-ten system. One key disadvantage however, is that the system is relatively ineffective in an offset impact (rather than directly head-on) since the engine can only absorb part of the collision energy. It is also unsuitable for cars with a transverse engine configuration.
The procon-ten system was available for cars such as the 100 / 200 and the V8, as well as the 80 / 90. It was discontinued in 1994, with the introduction of the new A4 and A8 series, and the 100-based Audi A6, all in 1994, for the 1995 model year.
An airbag is a vehicle occupant-restraint system using a bag designed to inflate in milliseconds during a collision and then deflate afterwards. It consists of an airbag cushion, a flexible fabric bag, an inflation module, and an impact sensor. The purpose of the airbag is to provide a vehicle occupant with soft cushioning and restraint during a collision. It can reduce injuries between the flailing occupant and the vehicle's interior.
Crumple zones, crush zones, or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change in velocity occurs from the impact during a collision by a controlled deformation; in recent years, it is also incorporated into trains and railcars.
Steering is the control of the direction of motion or the components that enable its control. Steering is achieved through various arrangements, among them ailerons for airplanes, rudders for boats, cylic tilting of rotors for helicopters, and many more.
The Audi 80 is a compact executive car produced by the Audi subdivision of the Volkswagen Group across four generations from 1966 to 1996. It shared its platform with the Volkswagen Passat from 1973 to 1986 and was available as a saloon, and station wagon — the latter marketed by Audi as the Avant. The coupé and convertible models were not badged as members of the range, but used a derivative of the same platforms.
The Audi A4 is a line of luxury compact executive cars produced since 1994 by the German car manufacturer Audi, a subsidiary of the Volkswagen Group. The A4 has been built in five generations and is based on the Volkswagen Group B platform. The first generation A4 succeeded the Audi 80. The automaker's internal numbering treats the A4 as a continuation of the Audi 80 lineage, with the initial A4 designated as the B5-series, followed by the B6, B7, B8, and the B9.
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel-drive and four-wheel-drive vehicles.
The Opel/Vauxhall Sintra is an automobile produced under the German marque Opel for the market in Europe between 1996 and 1999. It was sold in the United Kingdom as the Vauxhall Sintra. The Sintra was one of the second generation U-body large multi-purpose vehicles (MPV).
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.
The Chrysler Concorde is a full-size car that was produced by Chrysler from 1992 to 2004. It assumed the C-body Chrysler New Yorker Salon's position as the entry-level full-size sedan in the Chrysler brand lineup. One of Chrysler's three original Chrysler LH platform models, it has a front-engine, front-wheel-drive layout.
The Volkswagen Type 2 (T3) was the third generation of the Volkswagen Transporter. It was marketed under various nameplates worldwide – including the Transporter or Caravelle in Europe, Type 25 (T25) in the UK, Microbus and Kombi in South Africa/Brazil/Australia, Kampeerauto in Netherlands, Combi in France and Vanagon in North and South America.
The Ferrari Mondial is a mid-engined, V8, grand tourer manufactured and marketed by Ferrari between 1980 and 1993 – with styling by Pininfarina and bodywork by Carrozzeria Scaglietti.
The Audi V8 is a four-door, full-size luxury sedan, designed, manufactured and marketed by Audi in Germany from 1988 to 1993, as the company's flagship. As the first car from Audi to use a V8 engine, also was the first Audi to combine a quattro system with an automatic transmission. Early cars used 3.6-litre V8s, while later cars featured a 4.2-litre version of the engine. The Audi V8 was replaced by the Audi A8 in 1994, although the A8 was not marketed in North America until 1996.
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering.
A transverse engine is an engine mounted in a vehicle so that the engine's crankshaft axis is perpendicular to the direction of travel. Many modern front-wheel drive vehicles use this engine mounting configuration. Most rear-wheel drive vehicles use a longitudinal engine configuration, where the engine's crankshaft axis is parallel with the direction of travel, except for some rear-mid engine vehicles, which use a transverse engine and transaxle mounted in the rear instead of the front. Despite typically being used in light vehicles, it is not restricted to such designs and has also been used on armoured fighting vehicles to save interior space.
Torque steer is the unintended influence of engine torque on the steering, especially in front-wheel-drive vehicles. For example, during heavy acceleration, the steering may pull to one side, which may be disturbing to the driver. The effect is manifested either as a tugging sensation in the steering wheel, or a veering of the vehicle from the intended path. Torque steer is directly related to differences in the forces in the contact patches of the left and right drive wheels. The effect becomes more evident when high torques are applied to the drive wheels because of a high overall reduction ratio between the engine and wheels, high engine torque, or some combination of the two. Torque steer is distinct from steering kickback.

A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar (all-weather) and sometimes laser (LIDAR) and cameras to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
The Audi RS 2 Avant is a high-performance version of the Audi 80 Avant estate car, manufactured from March 1994 to July 1995. Collaboratively designed as a joint venture between Audi AG and Porsche and based on Audi's B4/8C platform, it received the internal designation of P1. It featured the most powerful version of Audi's inline-five cylinder turbocharged engine. It represents Audi's first "RS" model, and the first of their high-performance Avants.
The Audi R8 LMS Cup was a one-make sports car racing series by Audi based in Asia. Audi R8 LMS Cup cars were based on the Audi R8 LMS (GT3).
