DEFINITION

Suspension is the term given to the system of springs,shock absorber and linkages that connects a vehicle to its wheels and allows relative motion between the two.Suspension systems serve a dual purpose — contributing to the vehicle's roadholding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations,etc. These goals are generally at odds, so the tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front andrear suspension of a car may be different.

PEUGEOT RCZ

The 2010 Peugeot RCZ is the production version of the Peugeot 308 RCZ Coupe concept from the 2007 Frankfurt Motor Show.

The original concept was well received by both the press and public when it was unveiled, and thankfully the RCZ has remained faithful to the original design. Even some of the more extravagant styling cues like the little flick-up in the side window line, double-bubble roof, aluminium "roof arches", and bulging wheel arches have been carried over.

 The RCZ is intended to mark a new chapter in Peugeot's history. The car is supposed to be a specialist vehicle built in small numbers (for a major manufacturer like Peugeot), and rekindle a sense of driving excitement for the brand. Due to the special nature of the RCZ, it will be built by Magna Steyr in Austria in a production centre that specialises in exclusive vehicles built in small volumes. 

ELECTRONIC STABILITY CONROL (ESC)

Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology that improves the safety of a vehicle's stability by detecting and reducing loss of traction (skidding). When ESC detects loss of steering control, it automatically applies the brakes to help "steer" the vehicle where the driver intends to go. Braking is automatically applied to wheels individually, such as the outer front wheel to counter oversteer or the inner rear wheel to counter understeer. Some ESC systems also reduce engine power until control is regained. ESC does not improve a vehicle's cornering performance; instead, it helps to minimize the loss of control. According to Insurance Institute for Highway Safety and the U.S. National Highway Traffic Safety Administration,,one-third of fatal accidents could have been prevented by the technology.

SUSPENSION

Depending on the engine in your RCZ, it will have a different suspension setup and characteristics.

Diesel RCZ's (HDi 160/163) come with a standard suspension, standard steering and standard gearbox. The petrol RCZ's (THP 156/200) come with a sport suspension (extra torsion beam), a smaller steering wheel and a shorter gear lever. The sport suspension makes the car more direct and alert on each of the driver's commands. On the track the sports suspension is undoubtedly faster, but on public roads the standard suspension gives a more superior feeling because the RCZ performs with more ease. The THP 200 has an added lower anti-collision bar to give the car an even livelier and more agile handling response, while guaranteeing exceptional stability.

The RCZ benefits from a strong base, that of the "Platform 2" architecture consisting of a MacPherson setup with drop link anti-roll bar front suspension, and the rear suspension with a deformable crossmember, two arms and an integral anti-roll bar. It also has a particularly low ride height and centre of gravity, wider tracks and generous wheel dimensions (18" and 19"). Another feature to ensure peace of mind and safety while driving, is the intelligent traction control that comes standard with ESP.

Peugeot Early History

Peugeot is a major French car brand, part of PSA Peugeot Citroen, the second largest carmaker based in Europe.

The family business that precedes the current Peugeot company was founded in 1810, and manufactured coffee mills and bicycles. On 20 November 1858, Emile Peugeot applied for the lion trademark. The company produced its first automobile in 1891. Due to family discord, Armand Peugeot in 1896 founded the Societe des Automobile Peugeot. The Peugeot company and family is originally from Sochaux, France. Peugeot also retains a large manufacturing plant and Peugeot Museum there.
