    MEGANE RENAULTSPORT N4 RALLY CAR – SETTING A NEW STANDARD

    Noted for its striking design and having won acclaim for the quality of its chassis and engine, Mégane Renaultsport 250 is now to give rise to a rally car, N4, intended for private teams and drivers.

    As the only manufacturer to offer a full ‘rally’ range based on group R regulations, Renault Sport Technologies is now to add Mégane Renaultsport N4 to its line-up. Developed for racing on asphalt, it is set to establish a new standard.

    With the same intrinsic qualities as the Mégane Renaultsport 250, the new model draws on a heritage of group N-homologated Renaults stretching back over a quarter of a century: 5 GT Turbo, R11 Turbo, R21 2l Turbo, R19 16V, Clio Williams and Clio Renaultsport.

    Intended to keep costs down, group N regulations impose strict rules on the modifications that can be made to the original car. This constraint works to the advantage of the Mégane Renaultsport N4, which gets the full benefit of the technology used on the production model. The PerfoHub independent steering-axis front suspension design has allowed the engineers to put together a chassis that combines traction, directional stability and driving comfort in complete safety. The use of three-way adjustable shock absorbers also allows the settings to be adapted to all types of driving style.

    Under the bonnet, the performance of the 2.0-litre 16V turbo engine has been enhanced with an optimised electronic engine control system. Despite regulatory restrictions, the Mégane Renaultsport N4’s engine puts out 265hp and torque of 470 Nm. It is linked to a five-speed H-pattern gearbox, developed specifically for this purpose. On the strength of its experience in the field, Renault Sport Technologies has sought to design an innovative, reliable and high-performance package that also takes on board the notion of cost control at every stage of development. The intention is to make Mégane Renaultsport N4 accessible to all drivers, and be both easy to handle and economical to run. Like all of the vehicles in its rally range, Mégane Renaultsport N4 is to be sold by Renault Sport Technologies in the form of a kit comprising all the specific parts.

    MÉGANE RENAULTSPORT: THE PINNACLE OF PRODUCTION CARS BY RENAULT SPORT TECHNOLOGIES
    Unveiled in 2009, Mégane Renaultsport250 represents the pinnacle of production cars to date by Renault Sport Technologies. Acclaimed by the media and owners alike, it sets itself apart by virtue of its exceptional performance and roadholding. Powered by a four-cylinder 2.0 16V turbo engine generating 250hp and torque of 340 Nm, Mégane Renaultsport also stands out thanks to its characteristic chassis architecture, with the PerfoHub independent steering-axis front suspension which allows the steering and suspension to work independently of each other.

    To achieve perfect traction, the gearbox is equipped with a limited slip differential. Recognisable at first glance, the sporty design of Mégane Renaultsport is emphasised by the front bumper with its integrated F1-inspired aerodynamic blade, as well as the rear diffuser and centrally positioned exhaust outlet.

    GROUP N: THE SPIRIT OF PRIVATEER RACING
    According to the FIA, which determines the technical regulations, group N is open to mass production cars, more than 2,500 identical units of which must be produced over a period of 12 consecutive months. Created in 1982, group N is the category in which the cars are the closest to production models. The regulations permit very few limited modifications in order to keep costs down. Only minor modifications can be made to the engine, for example, compared to the production version – the ECU and exhaust line can be modified in accordance with strict rules. In order to guarantee reliability, the gearbox inners may be specific, but must be mounted in the original casing.

    MÉGANE RENAULTSPORT + GROUP N = MÉGANE RENAULTSPORT N4
    When developing Mégane Renaultsport N4, Renault Sport Technologies drew on the performance of the production model to derive a car which both performs and is economical to run, all in the spirit of the Group N regulations. Drivers will be in a position to achieve top-class results on tarmac, all within a reasonable and controlled budget. With 265hp to be transferred to the front wheels, the suspension on the Mégane Renaultsport N4 had to be impeccable. Thanks to the PerfoHub set-up and the very latest-generation shock absorbers, roadholding and traction are both equally impressive.

    STEER TO PERFECTION
    First used at the end of the 1980s on the Superproduction version of the R21 Turbo, the independent steering-axis front axle was first introduced on a production car on the Mégane Renaultsport. By allowing the suspension and steering to work totally independently of each other, this mechanism allows MéganeRenaultsport N4 to benefit from handling and grip of the highest quality.

    THE LATEST IN SUSPENSION SYSTEMS
    Designed in conjunction with Öhlins, the suspension consists of four spring-shock absorbers using the most recent technologies available. The hydraulic rebound shock absorbers are three-way adjustable (high and low-speed compression, rebound). This allows for a vast range of settings to fit the road profile, level of grip, weather conditions and driving style. The quality of these suspension systems allows drivers to get the most out of the BF Goodrich tyres, mounted on 18-inch rims, and release their full potential on long special stages.

    BRAKE SYSTEM
    At the front, Mégane Renaultsport N4 is fitted with 355mm-diameter discs and four-piston one-piece calipers. At the rear, the grooved disc taken from the standard production model is fitted with double-piston fixed calipers. As required by racing regulations, the ABS is disabled. Inside the cabin, a limiter system allows the driver to control rear braking pressure. In accordance with the regulations, the master cylinder and pedal assembly are taken from the production model. Essential on hairpins, a vertical lever-operated hydraulic handbrake has been added to the standard braking system.

    ENGINE AND GEARBOX: AT THE HEART OF EVERY RENAULT SPORT
    One of the major strengths to be carried over from MéganeRenaultsport250 is the F4Rt 1998 cc 16-valve turbocharged engine. With no specific preparation performed on its internal parts, Renault Sport Technologies guarantees control over budget and engine reliability. The main developments are to the engine flywheel and the electronic engine management system developed by Cosworth Electronics to enhance performance despite the adoption of a regulation 33mm turbo restrictor. The engine on the Mégane Renaultsport N4 generates a maximum power output of 265hp from 4000 rpm and maximum torque of 470 Nm at 3000 rpm. In order to optimise performance on special stages, the air intercooler can be sprayed with water. The specific exhaust line incorporates a catalytic converter compliant with FIA standards and an expansion chamber.

    GEARBOX SPECIFIC TO THE COMPETITION VERSION
    In order to guarantee reliability, the gearbox is the component on which there is the most room for specific preparation. The regulations impose an H layout and the fitting of the gearbox in its original casing.

    The gearbox on Mégane Renaultsport N4 is fitted with a self-locking limited slip differential (disc and ramp, «ZF»-type LSD). Several final torque settings enable the final gear ratios to be adjusted according to the specific characteristics of each event. The specific clutch system is supplied by AP Racing. The gearbox is also cooled by an oil radiator.

    SAFETY: NO COMPROMISE
    A priority in every phase of design and development, safety is an essential part of all the production and competition models developed by Renault Sport Technologies.

    The Mégane Renaultsport monocoque has been strengthened and stiffened to bring both active and passive safety close to perfection. The bodyshell is fitted with a welded roll cage, which is compliant with FIA regulations and has been validated by static load calculations. In the cabin, all the compulsory safety equipment is supplied by Sabelt. Two bucket seats fitted with HANS-compatible six-point harnesses, as well as an electrically-controlled automatic fire extinguisher system and a cut-out switch are all included as standard in the Mégane Renaultsport N4 racing kit.

    DESIGN AND ERGONOMICS: THE RENAULT SPORT BADGE
    Echoing the same sculpted design seen on Mégane Renaultsport250, the rally version emphasises the production model’s naturally sporty looks. The only addition is the roof-mounted air intake incorporated into the external lines of the car to distinguish the competition version from the production model. Benefiting from the assuredly sporty look of Mégane Renaultsport250, the N4 version also features the front bumper with an integrated F1-style aerodynamic blade. The centrally-positioned exhaust outlet and rear diffuser also emphasize its shared pedigree with the Mégane Renaultsport. The 18-inch alloy wheels, fitted with BFGoodrich tyres, means the aggressive overall lines have been retained. In the cockpit, once seated in the Sabelt bucket seats, driver and co-driver will find the production dashboard and central console. In addition to the standard equipment, the dashboard on the Mégane Renaultsport N4 also features an LCD screen which provides all the essential information on how the engine is running, as well as a tripmaster and LEDs for optimised gear changes.

    TECHNICAL SUPPORT: A TEAM THAT STANDS BY ITS CUSTOMERS
    Renault Sport Technologies provides comprehensive technical support for its entire range of racing products. Every year, Renault Sport Technologies’ operations engineers are present at dozens of rallies at both national and international level.

    Ongoing support, including a hotline available since 2003, ensures that all customers remain in direct contact with Renault Sport Technologies’ engineers, either by telephone or email.

    Ahh, gracias!
    Pues no es mala la idea. Otras marcas lo hacen, eso si, con otro tipo de coches…

    No. Dentro de los Renault Retail Group habra unos cuantos concesionarios que, ademas de la gama normal, estaran especializados en la venta de la gama RS y sus accesorios.

    Nada de independizar. Solo es crear un espacio en el concesionario donde ver la gama RS gordini con comerciales que sepan que es un RS.

    Por ahora solo serán unos cuantos RRG

    renault esta preparando en España concesionarios especializados en la gama RS, que ya existen en el resto de Europa.

    ¿Concesionarios exclusivos solo para los Rs?
    Parece como si los quisiesen “independizar” un poco no?

    Comercialmente me parece una jugada muy inteligente por parte de Renault Sport. Por un lado estan los ingresos nada despreciables de unidades de competición (cuantos Clio R3 o Cup se habrán vendido…), pero lo más importante es a nivel de imagen de marca.

    Renault étoffe sa gamme de voitures de rallye et présente la Mégane R.S. N4, destinée à devenir l’un des fers de lance du groupe N à partir de la saison 2011. Officiellement présentée fin novembre, Renault Mégane R.S. N4 est basée sur le modèle de série, avec un moteur 2.0 16V turbo équipé d’une bride de 33 mm. La gamme Compétition Clients de Renault Sport Technologies s’enrichit ainsi d’un sixième modèle, après les Twingo R1 et R2, et les Clio R3 « Access », « Maxi » et « Evo ».

    « Mégane R.S N4 reprend le train avant à pivot indépendant de la voiture de série, qui découple les fonctions de suspension et de guidage afin d’atteindre une tenue de route et une motricité de très haut niveau. Mis au point par Öhlins – comme sur toute la gamme rallye de Renault Sport Technologies – les amortisseurs à butée hydraulique sont réglables selon trois voies. Comme sur la voiture de série, le système de freinage fait appel à des composants Brembo spécifiques : disques de 355 mm (avant) et 290 mm (arrière), étriers monoblocs et frein à main hydraulique. Les roues de 18’’ sont chaussées de pneus BFGoodrich », révèle Renault Sport Technologies.

    « Sous le capot, la gestion électronique Cosworth Electronics permet d’exploiter tout le potentiel du moteur 2.0 16V turbo équipé d’une bride de 33 mm de diamètre. La transmission aux roues avant est assurée par une boîte de vitesses Sadev à crabots (5 rapports). Homologuée en classe N4, cette nouvelle voiture se destine à devenir une nouvelle référence sur asphalte. »

    La nouvelle arme de Compétition Clients de Renault Sport Technologies sera officiellement présentée lors du Rallye du Var (26-28 novembre) et devrait y effectuer ses premiers tours de roue en public, afin de débuter en Rallye lors de la saison 2011.
