A convincing demonstration in under eight minutes
The recently unveiled New Renault Mégane RS275 Trophy features the best of Renault Sport technology, with the Renault Sport 2.0L turbocharged petrol engine upgraded to 275 bhp and the Cup chassis. This limited series is now available in a more radical version: the New Renault Mégane RS275 Trophy-R, designed for track driving enthusiasts. Weighing in at almost 100kg lighter, the New Renault Mégane RS275 Trophy-R is pinned to the road by a chassis fitted with Öhlins Road&Track adjustable dampers and Michelin Pilot Sport Cup 2 tyres. The overall coherence is reflected in the exceptional level of performance achieved. As illustrated by a new record at the Nürburgring Nordschleife, the New Renault Mégane RS275 Trophy-R covered the 20.832 km in just 7’54’’36, the fastest time ever for a front-wheel drive production model.
“At Renault and Renault Sport in particular, we see new challenges as a driving force for our cars. After the first record was broken by the Renault Mégane R26.R in 2008, we wanted more. And today marks our return to Nürburgring in an attempt to improve our performance. This track – no doubt the world’s toughest – has become one of our working tools, used extensively for the fine-tuning of Renault Sport vehicles. Today, we are proud to present the New Renault Mégane RS275 Trophy-R, which becomes the flag bearer of our sporting range. The stopwatch has delivered its verdict: the New Renault Mégane RS275 Trophy-R delivers a performance worthy of an exclusive GT sports car.”

THE NEW RENAULT MEGANE RS275 TROPHY-R: RECORD BREAKER
Taking full advantage of the technology upgrades gained by the New Renault Mégane RS275 Trophy, this very special edition pushes the limits of high performance. Tipping the scales at almost 100kg less than the New Renault Mégane RS275 with a Cup chassis and 19” wheels (1,280kg compared with 1,381kg), this hardcore variant is even more dynamic and efficient. It features new equipment developed in cooperation with prestigious partners such as the Akrapovič titanium exhaust system, Öhlins Road&Track adjustable dampers, Allevard composite springs and Michelin Pilot Sport Cup 2 tyres.
The looks of the New Renault Mégane RS275 Trophy-R are as uncompromising as its technical specification. The two-tone version with Pearlescent White bodywork and an Etoilé Black roof is expected to be particularly popular.
The colours that set off the F1®-style aerodynamic front blade, stripes and side checkered flag graphics add touches of bright red to the bodywork. The black 19’’ Speedline Turini wheels, fitted as standard, are also available in red (option). The rear wiper has been removed in order to save another precious 1kg. This is the first visible sign of the systematic efforts devoted to making the car lighter.
Within the driver-focused cockpit, the Recaro Pole Position bucket seats illustrate the main purpose of the New Renault Mégane RS275 Trophy-R. These single-piece polycarbonate seats are painted glossy black and upholstered in leather and alcantara. Designed to bring weight savings of 22kg, they deliver a high level of side support for both the driver and passenger along with “unfiltered” feedback from the track. Alcantara is also present on the steering wheel and hand-brake gaiter, whereas leather is used for the gear knob. Available as an accessory, Sabelt six-point safety harnesses complete the equipment recommended for track driving.
The war against weight
To meet the ambitious targets for performance, ride and handling, engineers tracked down every last superfluous kilogramme. To combine function and pleasure, most of the insulating and absorbing materials (-18kg) were removed to enable the occupants to take full advantage of the sound made by the Akrapovič titanium exhaust system.
As the New Renault Mégane RS275 Trophy-R was made for track driving, the rear seats have been removed (-20kg) to make it a genuine two-seater. A cross strut bar is provided for the luggage restraint net. Track enthusiasts will appreciate the boot layout, designed to make it easy to carry four spare wheels. To protect the cabin, special wheel covers with the Renault Sport logo are available an accessory.
A further 10kg has been saved by removing the air-conditioning and radio, and fitting a simplified centre console. However, air-conditioning, radio and the Renault R-Link connected multimedia system are still available as options depending on the country.
Even more power with the Renault Sport 2.0L turbocharged engine
The New Renault Mégane RS275 Trophy-R comes with the latest upgrades to the Renault Sport 2.0L turbocharged petrol engine.
Engineers sought to increase torque when peak power is achieved at 5,500rpm by working on the electronic control parameters. By raising torque to 349Nm (+10Nm), they boosted engine power to 275bhp. Available between 3,000rpm and 5,000rpm, maximum torque of 360Nm remains unchanged. These results can be obtained by selecting Sport or Race modes via the R.S. Drive multi-mode management system.
The result of these efforts can be seen in the wider torque curve at higher revs. At the wheel, these developments deliver better acceleration in intermediate gears, for less frequent downshifts. This new engine definition has no impact on fuel consumption or CO2 emissions which remain contained at 7.5L/100 km and 174g/km*.
A sound signature by Akrapovič
Among the partners brought together by Renault Sport Technologies for the development of the New Renault Mégane RS275 Trophy-R, Akrapovič is making its voice heard! Renowned for its work with motorcycles and supercars, the Slovenian firm designed a special exhaust system in partnership with Renault Sport. The titanium exhaust, running from the intermediate silencer to the tail, cuts vehicle weight by 4kg. The carbon tailpipe trim is also by Akrapovič.
This assembly gives New Renault Mégane RS275 Trophy-R a deeper and more raucous sound signature that is sure to thrill engine aficionados!

A chassis of infinite potential
The New Renault Mégane RS275 Trophy-R is based on the Cup chassis, which features a Limited Slip Differential (LSD). Designed to improve traction in sports driving, this system delivers dependable efficiency at all times, regardless of grip conditions, driving style or type of curve. The LSD is combined with an independent steering-axis layout, allowing drivers to reap the full benefits of the extra traction for more reassuring handling.
Unanimously recognised as a model of rigour and precision, the Cup chassis takes advantage of the additional potential created by the latest developments from Renault Sport and its partners:
Adjustable suspension for controlled efficiency on all surface types
New from Öhlins, the Road&Track dampers were inspired by the world of motorsport. Unlike the conventional models with rods, these carefully crafted gems feature a sliding cartridge. This layout reduces the shear forces that can “block” the moving rod.
The new dampers feature Dual Flow Valve (DFV) technology, a major innovation that functions on both rebound and compression. The speed of operation, at both low and high frequencies, keeps the tyre in contact with the ground under almost all circumstances. In the event of heavy usage, the internal bleed valve maintains consistent damping quality even when the fluid heats up.
As requested by Renault Sport, the Öhlins Road&Track dampers are fitted with a hydraulic compression stop at the front. The Progressive Damping System (PDS) provides additional damping capacity at the end of the compression phase, when the car brakes hard or hits a bump.
Drivers can adjust the dampers using the knob on a rig fitted on the damper. An audible click confirms each change. With 20 positions at the front and 30 at the rear, the car adapts precisely to all types of surfaces and driving styles.
Drivers can also vary the body height and attitude of the New Renault Mégane RS275 Trophy-R by adjusting the compression of the Allevard composite springs. These corrosion proof springs have a longer service life. They also reduce vehicle weight by a further 2kg. Renault Sport is once more demonstrating its avant-garde approach with this solution, which is new on this type of vehicle.
To support inexperienced drivers, online tutorials and set-up sheets will be available on the www.renaultsport.com website in the near future. The database will be updated regularly based on customer feedback.
Tyres on par with the high performance chassis
Even the best chassis is useless without the right tyres to connect it to the road. To address the challenge from Renault Sport, Michelin developed a special version of its Pilot Sport Cup 2 tyres. Fitted on many supercars, this high-performance tyre is now available for the first time as standard on a front-wheel drive vehicle.
Starting from the suspension settings that are most demanding for tyres, Michelin engineers submitted a number of alternatives to Renault Sport test drivers. Following the tests conducted on several tracks (Nürburgring and Michelin technology centers in Ladoux, Charade and Jerez), a new version was jointly approved.
The characteristics of the Michelin Pilot Sport Cup 2 tyre include:
The Michelin Pilot Sport Cup 2 has all the qualities necessary to take full advantage of the potential of the New Renault Mégane RS275 Trophy-R: precise steering, stability, grip and sporting performance. Furthermore, two others qualities can be added: endurance (for lapping and also with respect to the service life of the casing) and versatility (for safe driving in all weather conditions).
The tyres are mounted on 19” Speedline Turini alloy rims. This new alloy rim design, based directly on the world of motorsport, reduces the unsprung weight of the vehicle by 5kg.
Breaking new ground in performance through a range of accessories
Renault Sport is bringing purists a range of accessories to boost the technical specifications of their New Renault Mégane RS275 Trophy-R to the same level as those of the Nürburgring record-setting version. Hailing from the world of motorsport, the “Performance” braking kit comprises of wider discs – with a diameter of 350mm, up from the standard 340mm – mounted on aluminum bowls. Using aluminum reduces the unsprung mass by 3kg, while the use of wider discs leads to a 100°C reduction in the operating temperature. The result on circuits is greater consistency and heightened pedal feel. In another bid to reduce mass, the accessories range includes a lithium-ion battery, weighing in at 16kg lighter. The lithium-ion battery is fitted in the same place as the original lead battery.
A “Nürburgring Pack”, comprising the “Performance” braking kit, lithium-ion battery, two Sabelt safety harnesses, four spare wheel covers and a retaining strap, will be available at a competitive price. The Accessories range is available at www.renaultsport.com.
7’54”36: THE NEW RENAULT MEGANE RS275 TROPHY-R SHOCKS THE CLOCK AT NÜRBURGRING
The New Renault Mégane RS275 Trophy-R was designed with a big challenge in mind: to set a new record on Nürburgring’s northern loop, the legendary Nordschleife. On May 15, 2014 at 7.15am, Renault Sport’s driver set off on a 20.832 km route in pursuit of that goal. Seven minutes and fifty four seconds later, the pressure subsided and gave way to joy!
Renault Sport set a new Nordschleife lap record of 8 minutes and 17 seconds with the Renault Mégane R26.R on June 23, 2008. With that achievement, Renault demonstrated that a production front-wheel-drive car could rival the performance of GTs. Three years later, on June 17, 2011, the Renault Mégane RS265 Trophy shaved nine seconds off the time set by its forerunner. Nonetheless, since records as meant to be broken, the idea of going under the symbolic eight-minute mark gradually began to form at Renault Sport.
On April 16, 2014, the #UNDER8 keyword started to trend in social media. The most astute web users were quick to understand the point of the campaign, namely that the experts at Renault Sport Technologies were out to set a new record over the Nordschleife’s 20.832km track.
Two main changes were made to the model chosen to take up the challenge, the limited series New Renault Mégane RS275 Trophy, whose mass was reduced and chassis potential enhanced. The result: The New Renault Mégane RS275 Trophy-R.
For its world record attempt, the Renault Sport squad targeted two days, Wednesday, 14 and Thursday, 15 May. As the circuit is open to other carmakers from 8am onwards, the time-slots are particularly tight and cars have to take to the track between 7.15am and 7.45am. In theory, early mornings are far from ideal in terms of track conditions but the atmospheric pressure at that time of day is conducive to getting the best possible performance out of the engine.
Things looked gloomy for the team on Tuesday evening, as it was raining and temperatures were barely above 5°C. The track was soaking wet on Wednesday morning, making any attempts futile. Conditions were hardly better on Thursday morning, but the track did appear relatively dry.
Laurent Hurgon, the Renault Sport test driver, decided to head out on a reconnaissance mission. The circuit was dotted with wet patches but nothing that seemed insurmountable. The temperature of the Michelin Pilot Sport Cup 2 tyres rose slowly as the driver meticulously noted the right trajectories to take in the most delicate sections, among them the Karussell and Pflanzgarten corners.
Laurent set off as soon as all systems were ready to go. The first section of the Nordschleife circuit is incredibly fast. Travelling at over 190km/h, the New Renault Mégane RS275 Trophy-R started to
skid on a wet patch. With a single move of the wheel, Laurent brought the car back in line. A few tenths of a second were lost but they were soon made up for in the most demanding curves.
At the other end of the circuit, the BRM stopwatch was clocking up the seconds. Everyone on hand held their breath as the car gunned toward the finish line. The time displayed was 7’54’’36 – and the mission successfully accomplished!
