The Alpine A110 E-ternité, 100% electric, is the result of this exploratory work. It comes to celebrate the 60th anniversary. Bridging from a prestigious past to a 100% electric future, it illustrates the work which Alpine currently implements to develop its range of new models. For more than ten years, Renault Group has been a pioneer in the field of electric vehicles and has acquired a wealth of valuable experience in all areas of the automotive industry. It is therefore quite natural that the Alpine teams began thinking about the subject very early on. The arrival of Luca de Meo and the announcement of a 100% electric range at Alpine gave a clear direction for the work of the teams and an opportunity to work on electrics in an exploratory way. In the “restomod” spirit, the A110 has become the ideal platform for this research work, a bridge between a prestigious past and an even more ambitious future. Thus, the target is clear: to electrify the next Alpine vehicles, and why not starting by the A110, a paragon of sportiness known for its light weight and agility, within a realistic budget.
In order to get away from the 0 to 100kph / top speed trade-off and the constant quest for electric storage that requires large batteries, an innovative gearbox was added to the Group’s “standard” motor. No gearbox available in-house allowed the Alpine engineers to meet the brief requirements of this A110 E-ternité. The desire was to find a smooth and efficient gearbox without torque breakage, but also light and compact. A gearbox was studied in-house, with the Alpine gearbox supplier, in double clutch version (DCT) with an electronic control, as on the A110 combustion engine, but with clutches dimensioned to pass high torques. As a Renault Group brand, it was natural, for this new project, to look first at the parts and technologies already available in-house. The battery modules are identical to those of the 100% electric Mégane E-Tech. Despite the addition of these twelve modules, the total weight of the Alpine A110 E-ternité remains particularly light with an increase of only 258 kg, thanks to a contained mass for the battery pack (392 kg).
The mandate was simple: electrify the A110 and match the performance, balance and agility of the Alpine A110 combustion engine car while capitalizing on the Group’s strengths, experience and technologies.
To spice up this challenge a little more, Alpine is going to add four innovations to the mandate:
an innovative multimedia system using the driver’s personal tablet for an intuitive and natural connectivity experience, based on Google or Android, allowing all the user’s applications to be centralised on a single device
a “top-off” solution that allows you to enjoy the quietness of the electric technology: a dream to drive an electric Alpine A110 in the open, without a sound.
a state-of-the-art audio system with 8 speakers to recreate surround sound.
innovative materials to combine performance and sustainability
For a long time, the demands for a convertible A110 have been heard. Alpine decided to take on one more challenge at the same time. The difficulty was above all to find the solution to quickly integrate a removable roof on the structure of the Alpine A110. The Alpine engineers thus imagined a simple and light solution, without impacting the rigidity of the production A110, with two roof shells injected with recycled carbon. A component designed and built entirely in-house. Both lightweight and more environmentally friendly, the materials used on some key parts are made from flax. A second E-ternité demo-car was also developed and displays this new technology applied to parts such as the skin of the bonnet, roof, rear window, grille, seat shells and rear skirt. The material comes from the Terre de Lin company based near Dieppe (Normandy, France). As strong as carbon-fibre and with better acoustics, flax is a material of the future. This new experience also makes it possible to prepare for the future. Indeed, the design of the parts is now compatible with the various composite materials, which means that the same mould can be used to produce carbon, glass or flax fibre composite.
