2013 IAA: Renault TwinRun Concept announces the next-generation Twingo [Live Photos]

Article by Anita Panait, on September 12, 2013

Renault brought its Twin'Run concept at the 2013 Frankfurt Motor Show, next to the Initiale Paris Concept and the facelifted Megane. The concept provides a glimpse of the performance potential of a possible Twingo RS model in the future. Regarded as a spiritual successor to the R5 Turbo and Clio V6, the Twin'Run concept bears the same funky city car styling cues as the Twin'Z electric car concept that Renault unveiled in April.

However, the Twin'Run is not powered by batteries and instead, it features a mid-mounted 316bhp V6 petrol engine and is fitted with motorsport technology designed to provide a glimpse of the next-generation Twingo RS.

While providing power to the rear wheels, Twin'Run’s V6 engine combines with a tubular steel chassis derived from the Megane Trophy racer and lightweight fiber glass bodywork for a kerbweight of just 950kgs.

This power and lightweight combo allows the Twin'Run to propel from zero to 62mph in just 4.5 seconds and achieve a top speed of 155mph.

The Twin'Run boasts of motorsport mechanicals like a six-speed sequential gearbox, rally-style welded handbrake lever, huge brakes and a limited-slip differential at the back. The concept rides on 18-inch alloy wheels pushed to each corner. The concept features exterior styling influenced by iconic rally cars, with orange graphics running along the roof and doors, big air vents in front of the rear arches and a fixed rear wing.

Twin'Run’s 25mm-thick front quad LED lights could provide different light sequences as controlled by the driver. The concept’s interior is stripped out, with only a plexiglass sheet separating the driver from the V6 engine.

It also features sparco bucket seats with four-point race harnesses. Axel Breun, head of concept car design for the Renault, remarked that the Twin'Run “embodies the mad genius Renault has been known for over the decades.”

At its launch, the Twin'Run was driven for several laps around Monaco Grand Prix circuit by Renault boss Carlos Tavares. It was joined by a convoy that included a Clio V6 piloted by F1 driver Charles Pic and a Maxi 5 Turbo driven by rally legend Jean Ragnotti.

The bodywork in a glass-polyester composite has additionally profited from racing knowledge. This incorporates carbon fiber for the front blade, roof, rear vent and wheel arches.

Carbon fiber innovation integrates sophistication and performance, while lowering the production costs.

COMPETITION AERODYNAMICS

The two-box structure of Twin'Run generates lift at high speeds. The aerodynamics has gotten unique treatment with a vent directing the air flow beneath the car and a fixed airfoil for improved aerodynamic support at high speeds.

A RACING CHASSIS

Twin'Run lays on a multi-tube superior steel chassis gotten from aeronautics and utilized in competitions. The chassis was created exclusively by Tork Engineering.

The ground link is given by front and rear axles fitted with double-wishbone suspension with autonomous pivots. The four pivots, in strong aeronautical quality aluminum, provide superior efficiency on the track. For precise filtering and maximum body stability, Twin'Run is fitted with OHLINS spring shock absorbers at the front and rear.

The axles are installed with an anti-roll bar with a diameter of 22 mm at the front and 25 mm at the rear. Roll is flawlessly controlled for dexterity and receptivity.

Press Release

Renault Twin-Run Concept

Renault is unveiling the Twin'Run at the 2013 Monaco Grand Prix. The new concept car cultivates the sporting spirit of the brand and celebrates automotive passion by paying homage to the legendary R5 Turbo and Clio V6.

Twin'Run, a real racing car, features a tubular chassis lifted directly from motorsport competition and a mid-engine 320-hp V6 engine based on Mégane Trophy.

Like its twin, Twin'Z, Twin'Run is a modern and playful take on the city car. Both concept cars express the fifth stage in Renault's design strategy based on the major phases in a lifetime. Each in its own way represents the "Play" stage (petal) and demonstrates the customisation possibilities of a city car fully in step with its times.

The Twin'Run concept car previews the styling of Renault's future city car.

TWIN'RUN: A PASSIONATE CONCEPT CAR GOING BACK TO ITS ROOTS

Twin'Run drove its first laps in front of spectators at the Monaco Grand Prix. Monaco, with its legendary track, is the ideal theatre for the concept car's debut. Twin'Run is a sports car through and through and further cultivates the Renault brand's passion for racing, picking up where the famous R5 Turbo and Clio V6 left off.

The public at Monaco got to see the three racers in action in a pursuit race organized to celebrate Renault motorsport history. Twin'Run led the way with Carlos Tavares, Chief Operating Officer, at the wheel, tailed by a Clio V6 driven by F1 star Charles Pic and a Maxi 5 Turbo with its celebrated driver, Jean Ragnotti, at the helm.

Twin'Run ties in perfectly with the series of concept cars illustrating Renault's design strategy. The diamonddominated front end underscores the brand identity in line with Renault's new styling approach. Like Twin'Z, Twin'Run gets blue paint in reference to the "Play" petal of the fifth stage in the brand's design strategy. Twin'Run's stomping ground is the world of motorsport.

TWIN'RUN: COMPACT, POTENT AND PLAYFUL

Twin'Run, has a compact, ultra-dynamic body. The wheels set in the far corners, minimal overhang and high waistline underscore the dynamic feel and promise a great drive.

BLUE AND RED

The blue paint finish on Twin'Run features taut, graphically drawn lines with emphatic shoulders enhanced by touches of red on the strip running all the way along the body and above the rocker panel, as well as two red bands on the roof.

Red also figures at the front, where it underlines the grille and air intakes, and on the ultra-slim door mirrors and the tips of the rear airfoil. A red surround emphasises the circumference of the black and white wheel rims.

HOMMAGE TO A PRESTIGIOUS FORERUNNER

The "5" on the doors refers to the R5 Turbo, the emblematic 1980s rally car. A host of details pay homage to this illustrious forerunner, including the design of the headlights and the generous haunches at the back. The four additional, extra-flat headlights with LED technology are a modernday take on the light racks used in nighttime rally specials. The fully customisable light sequences are controlled by an in-car system. The development of this system was a real challenge as the designers had to provide a powerful light source in a lamp measuring just 25 mm deep.

TWIN'RUN: A REAL RACING CAR

Twin'Run was developed with the assistance of Tork Engineering / Poclain Vehicules, a French firm specialised in the preparation of chassis for competition. The concept car is a real racing car that has benefited from that competition expertise. The bodywork in composite material covers a multi-tube steel chassis powered by a mid-engine engine derived from Mégane Trophy.

A V6 ENGINE FOR COMPETITION

Twin'Run is fitted with the V4Y engine from the Renault-Nissan Alliance, which is used on the road for Laguna, Espace and Latitude but also used in competition with Mégane Trophy. Mounted longitudinally ahead of the rear axle centerline, the V6 3,498 cc power plant delivers 320 hp at 6,800 rpm and torque of 380 Nm at 4,850 rpm. The engine is full-bodied and generous from low revs, delivering linear acceleration and providing excellent traction around bends and in acceleration.

The V6 is mated to a SADEV six-speed sequential gearbox with limited slip differential, enhancing Twin'Run stability and traction in curves. The twin metallic clutch is also borrowed directly from competition.

The air intake vents are positioned at the level of the rear wheel arches. Air extractors in the rear quarter lights help keep the engine cool.

The cooling system has received special treatment with polished aluminum pipes set visibly into the cabin floor. The engine is separated from the driving position by a plexiglass panel.

To ensure good weight distribution despite the mid-engine architecture, various components were positioned under the bonnet. These include the fuel tank, the radiator and the hydraulic system. The concept car is well balanced with a 43/57 weight distribution.

COMPOSITE BODY

The bodywork in a glass-polyester composite has also benefited from racing expertise. This includes carbon fibre for the front blade, roof, rear vent and wheel arches.

Carbon fibre technology combines aesthetics and efficiency, while keeping costs down.

COMPETITION AERODYNAMICS

The two-box architecture of Twin'Run creates lift at high speeds. The aerodynamics have received special attention with a vent channeling the air flow under the car and a fixed airfoil for enhanced aerodynamic support at high speeds.

A RACING CHASSIS

Twin'Run rests on a multi-tube high-performance steel chassis derived from aeronautics and used in competition. The chassis was developed entirely by Tork Engineering.

The ground link is provided by front and rear axles fitted with double-wishbone suspension with independent pivots. The four pivots, in solid aeronautical quality aluminum, deliver high performance on the track. For filtering and body stability, Twin'Run is fitted with OHLINS spring shock absorbers at the front and rear.

The axles have an anti-roll bar with a diameter of 22 mm at the front and 25 mm at the rear. Roll is perfectly controlled for agility and responsiveness.

The aluminum wheel covers with a special hub with a central bolt can be dismounted in three parts and fit 18" Michelin tires.

A CABIN DEDICATED TO PERFORMANCE

Twin'Run has the cabin of a sports car, as indicated by the tubular chassis and SPARCO seats fitted with safety harnesses. Nevertheless, the emphasis placed on interior design extends well beyond anything normally seen in the world of motorsports.

The door panels and dashboard are upholstered in black and red "alcantara effect" suede. The padded bucket seats, upholstered in three shades of alcantara and carrying the Twin'Run signature, underline the French touch of this concept car.

The driver gains a motorsports steering wheel and sequential gear lever with a high-mounted layout for fast gear changes. The joint welded handbrake is positioned on the same level as the gear lever for demonstration figures such as a 360° rotation.

Under the driver's feet, the aluminum pedal assembly is a motorsports model. Designed for easy heel-toe moves, it has been tried and tested on many track vehicles (Lodgy Andros / Duster No Limit).

Positioned in a white lacquer console, the instrument cluster is dedicated first and foremost to driving, as on any sports vehicle.

Twin'Run features a 5.5 inch LCD screen positioned just behind the steering wheel. The red and blue multi-page display shows the vehicle speed, gear speed and engine speed, as well as fuel pressure, clutch pressure and oil pressure.

Two red pressure gauges with centrally positioned needles show the oil temperature and water temperature, a last nod to the R5 Turbo.
