SETTING A NEW STANDARD ON TARMAC NOTED FOR ITS STRIKING DESIGN AND HAVING WON PLAUDITS FOR THE qUALITY OF ITS CHASSIS AND ENGINE, MéGANE R.S. IS NOW TO GIVE RISE TO A RALLY CAR INTENDED FOR PRIVATE TEAMS AND DRIVERS. DEVELOPED FOR RACING ON ASPHALT, MéGANE R.S. N4 IS SET TO ESTABLISH A NEW STANDARD ON THAT SURFACE.

As the only manufacturer to offer a full ‘rally’ range based on group R regulations, Renault Sport Technologies is now to add Mégane R.S. N4 to its line-up. With the same intrinsic qualities as the Mégane R.S., the new model draws on a her-itage of group N-homologated Renaults stretch-ing back over quarter of a century: Supercinq GT Turbo, R11 Turbo, R21 2l Turbo, R19 16S, Clio Williams and Clio Renault Sport.

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 R.S. N4, which gets the full benefit of the technology used on the production model. The independent steering-axis front suspen-sion design has allowed the engineers to put together a chassis that combines traction, directional stabil-ity 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-li-tre 16V turbo engine has been enhanced with an optimized electronic engine control system. De-spite regulatory restrictions, the Mégane R.S. N4’s engine puts out 270 bhp and torque of 470 Nm. It is linked to a five-speed H-pattern dog ring gearbox, developed specifically for this purpose.

On the strength of its experience in the field, Re-nault Sport Technologies has sought to design an innovative, reliable and high-performance pack-age that also takes on board the notion of cost control at every stage of development. The inten-tion is to make Mégane R.S. N4 accessible to all drivers, and be both easy to handle and economi-cal to run.

Like all of the vehicles in its rally range, Mégane R.S. N4 is to be sold by Renault Sport Technologies in the form of a racing kit bundling all the specific parts.

FROM PRODUCTION TO COMPETITION

MéGANE R.S.: AUTOMOTIVE PLEASURE AT ITS PEAK

Unveiled in 2009, Mégane R.S. represents the peak of automotive pleasure as made by Renault Sport Technologies. Acclaimed by the press and well-received by drivers, it sets itself apart in virtue of its exceptional performance and road-holding.

Powered by a four-cylinder 2.0 16V turbo en-gine generating 250 bhp and torque of 340 Nm, Mégane R.S. is also notable for its characteristic chassis architecture, with a independent steer-ing-axis front axle 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.

Recognizable at first glance, the sporty design of Mégane R.S. is emphasized by the front bump-er with its integrated F1-inspired aerodynamic splitter, 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 techni-cal 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 modi-fications can be made to the engine, for exam-ple, 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 R.S. + GROUP N = MéGANE R.S. N4

When developing Mégane R.S. N4, Renault Sport Technologies drew on the performance of the production model to derive a car which both per-forms and is economical to run, all in the spirit of the Group N regulations. Drivers will be in a posi-tion to achieve top-class results on tarmac, all within a reasonable and controlled budget.

GROUND LINK: STUCK TO THE ROADWith 270 bhp to be transferred to the front wheels, the suspension on the Mégane R.S. N4 had to be impeccable! Thanks to the independent steering-axis front suspension and the very latest genera-tion of shock absorbers, roadholding and traction are quite simply flawless.

STEER TO PERFECTION

First used at the end of the 1980s on the Super-production version of the R21 Turbo, the independ-ent steering-axis front axle was first introduced on a production car on the Mégane Renault Sport. By allowing the suspension and steering to work to-tally independently of each other, this mechanism allows Mégane R.S. N4 to benefit from roadholding and traction of the highest quality.

THE LATEST IN SUSPENSION SYSTEMS

Designed in conjunction with Öhlins, the suspen-sion consists of four spring-shock absorbers us-ing the most recent technologies available. The hydraulic rebound shock absorbers are three-way adjustable (high and low-speed compres-sion, rebound). This allows for a vast ranges 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 BFGoodrich tyres, mounted on 18-inch rims, and release their full potential on long special stages.

STIFFER BRAKING

At the front, Mégane R.S. N4 is fitted with 355 mm-diameter floating discs and four-piston one-piece calipers. At the rear, the grooved disk taken from the standard production model is fit-ted 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 axle braking pressure.

In accordance with the regulations, the master cylinder and pedal assembly are taken from the production model. Essential on hairpins, a verti-cal lever-operated hydraulic handbrake has been added to the standard braking system.

ENGINE AND GEARBOX: AT THE HEART OF EVERY RENAULT SPORTOne of the major strengths to be carried over from Mégane R.S. is the F4Rt 1998 cc 16-valve tur-bocompressed engine. With no specific prepara-tion performed on its internal parts, Renault Sport Technologies guarantees control over budget and engine reliability.

The main developments are to the engine fly-wheel 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 R.S. N4 generates a maximum power output of 270 bhp from 4000 rpm and maximum torque of 470 Nm at 3000 rpm.

In order to optimize performance on special stages, the air/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 dog ring gearbox on Mégane R.S. 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 develop-ment, safety is an essential part of all the produc-tion and competition models developed by Renault Sport Technologies.The Mégane R.S. monocoque has been strength-ened 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 har-nesses, as well as an electrically-controlled au-tomatic fire extinguisher system and a cut-out switch are all included as standard in the Mégane R.S. N4 racing kit.

DESIGN AND ERGONOMICS: THE RENAULT SPORT BADGEEchoing the same sculpted design seen on Mégane R.S., the rally version emphasizes 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 competi-tion version from the production model.

Benefiting from the assuredly sporty look of Mé-gane R.S., the N4 version also features the front bumper with an integrated F1-style aerodynamic splitter. The centrally-positioned exhaust out-let and rear diffuser also emphasize its shared

pedigree with the Mégane R.S. 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 produc-tion dashboard and central console. In addition to the standard equipment, the dashboard on the Mégane R.S. 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 optimized gearshifting.
