The new front-end look, with the upright, confident diamond, has been adapted for this very low and wide car. The Renault Alpine A 110-50 is a car of today; a bold embodiment of Renault's passion for motorsport.

"For everybody on the team, it was a dream come true to work on an Alpine concept car. We wanted to put this car firmly in the modern day, while resonating with its heritage" Laurens van den Acker, Senior VP, Corporate Design.

The Renault Alpine A 110-50 concept car translates the most characteristic design features of the original A 110 in a modern and spectacular way with:
  • the sculpted forms of its elegant, flowing bodywork, enhanced by lights over which air seems to flow effortlessly.
  • the half-domed additional lamps, with a technical but nostalgic interpretation, thanks to full LED yellow lighting - as it should be
  • a characteristic 3D rear window, which reveals the mid-rear engine.
  • air intakes on each side echo the ducts on the rear wheel arches of the Berlinette. The right-hand opening is for gearbox cooling, the left is for the engine bay.
Produced by Faster, the carbon-fibre bodywork features a new shade of blue which refreshes and reinterprets the famous original 'Alpine Blue'. Every opening panel does so with dynamics worthy of the finest GTs, with the bonnet hinged at the front and the engine bay cover opening towards the rear. The doors feature a scissor motion.

"The car is very curvy, like the Berlinette, while expressing the three key words of our new design policy: simple, sensual and friendly"Axel Breun.

As you climb into the driving seat, the eye is drawn to the carbon-fibre sills. Everything inside this two-seater expresses build quality and sportiness, with black dominant throughout:
  • the driver's seat features embroidered 'Renault Alpine A 110-50' badging, Sabelt full harness belts and alternate, attractive shades of blue.
  • the dashboard is particularly uncluttered. The Renault Design-created steering wheel incorporates a colour screen and houses the same technology as a Formula Renault 3.5 single-seater to provide drivers with all the information they need.
  • Racing driver equipment is provided by Sabelt and the helmet is created by Ruby.
Produced with the renowned expertise of Renault Sport Technologies, the Renault Alpine A 110-50 is imbued with the world of motorsport. It benefits from the experience gained from the Mégane Trophy race car by using the same technical platform. Acclaimed by drivers in the WORLD SERIES by RENAULT, the tubular chassis of the Renault Alpine A 110-50 has been stiffened and undergone several developments. The roll cage and bracing in the engine bay have been modified (lowered) in the workshop of Tork Engineering to adapt them to the vehicle's height, which is lower than that of Mégane Trophy. The digital design work was led by Renault Design, Koller and Etud Integral, while final assembly was carried out by Protostyle. The final weight distribution is almost ideal, with 47.8% over the front wheels.

To facilitate servicing, the concept car features integral pneumatic jacks. Derived directly from the systems seen in endurance racing, they allow the wheels to be changed extremely quickly.

The efficiency of the Renault Alpine A 110-50 concept car is largely generated by ground effect. At the front, a splitter hidden in the bumper generates low pressure, which results in significant aerodynamic downforce. At the rear, a diffuser accelerates air flow beneath the floor. Ground effect therefore accounts for more than one-third of the car's downforce, with the rest coming from an adjustable rear wing.

The research and design of this air flow was conducted using Computational Fluid Dynamics, a cutting-edge technology used particularly in F1. CFD involves studying movements of a fluid, or their effects, by resolving digitally the equations which govern the fluid. This technique was used by Renault Sport Technologies primarily in order to fine-tune the aerodynamics and study the behaviour of the New Mégane Trophy as a function of air flow.

The wheelbase of the Renault Alpine A 110-50 is identical to that of Mégane Trophy (2,625mm), while the track is slightly wider at 1,680mm front and 1,690mm rear.

The 21-inch wheels, with a single central nut, are specific to this car and fitted with road-homologated Michelin tyres.

The Sachs dampers can be adjusted in compression and extension, and are mounted directly onto the lower wishbones. There are numerous different set-up options: castor, camber and alignment, ride height, anti-roll.

In order to improve driver feedback and provide the purest driving experience possible, driving aids like ABS, traction control, etc. are not fitted.

The braking capability of the Renault Alpine A 110-50 match its performance. At the front, large 356mm-diameter steel discs are slowed by six-piston callipers. At the rear, the discs are 330mm in diameter, while the callipers are four-piston models.

Developed on the same technical platform as Mégane Trophy, the Renault Alpine A 110-50 concept car also boasts the same chief technical characteristics.

It runs the Renault V4Y engine block, a 3.5 litre 24-valve 400hp V6 mounted in a mid-rear position. The crankcase (semi-wet), moving parts (pistons, connecting rods, crankshaft), valve train (camshafts and valve springs) and exhaust system are specific compared to the version featured on productions models.

Furthermore, the Renault Alpine A 110-50 uses the carbon air intake employed for Mégane Trophy V6.

The inlet manifold is fed by a new roof-mounted air intake. This development broadens the engine's power band, with additional horsepower at all engine speeds. The engine mapping has been optimised for these modifications.

The Renault Alpine A 110-50 concept car is fitted with a semi-automatic six-speed sequential gearbox, as well as a twin-plate clutch that can be controlled using either the clutch pedal or a paddle on the steering wheel.

The gearbox is fitted longitudinally behind the engine and incorporates a limited-slip differential (discs and ramps) with adjustable pre-loading. The cerametallic twin-plate clutch is also specific to the car. It is activated automatically when downshifting, guaranteeing fast and reliable gear changes.

Supplied by Magneti-Marelli, the Marvell 6R electronic control unit includes functions for engine management, gearbox control and data acquisition.

All data collected by the Renault Alpine A 110-50 can be analysed using version 4 of the benchmark Wintax software. Wintax 4 enables advanced analysis of more than 50 parameters: engine speed, gear, steering angle, car speed, throttle position, brake pressure... This information allows drivers and engineers to optimise settings and driving style. Wintax 4 data analysis also enables even faster diagnosis of any technical problems.
