Renault Alpine A110-50

A new interpretation of a timeless design

To mark the 50th anniversary of the iconic Berlinette, Design Yann Jarsalle and Concept and Show Car Director Axel Breun reinterpreted the original design cues to include the new Renault design language introduced by Laurens van den Acker with the DeZir concept car, and which will soon be rolled out in the company’s future models. The new front-end look, with the upright, confident diamond, has been adapted for this very low and wide car. The Renault Alpine A110-50 is a car of today; a bold embodiment of Renault’s passion for motorsport.

An exceptional car that fuses elegance and aerodynamic efficiency

The efficiency of the Renault Alpine A110-50 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 A110-50 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, driving aids like ABS, traction control, etc. are not fitted.

The braking capability of the Renault Alpine A110-50 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.

Mechanical excellence

Developed on the same technical platform as Mégane Trophy, the Renault Alpine A110-50 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 A110-50 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 optimized for these modifications.

The Renault Alpine A110-50 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.
