Alpine A110 E-ternite Concept (2022)

A GEARBOX SPECIFICALLY DEVELOPED BY ALPINE

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. The double clutch solution makes it possible to avoid a break in torque while remaining compact and light.

ELECTRONIC SYSTEM: A SUCCESSFUL TRANSPLANT OF TWO TECHNOLOGIES

The Alpine team showed ingenuity on the electronic system, mixing two electronic equipment architectures separated by ten years. This innovation provides new opportunities for architecture simplification or continuous improvement throughout the product as it enabled the features of the combustion engine AS1 to be kept whilst adding new features from the EV sector, as well as others such as the "Overtake" feature or the possibility of enabling communication between two batteries.

A single ECU was installed to ensure communication between the two systems. This innovation brings new opportunities for simplifying architectures or for continuous improvement throughout the product life cycle.

INNOVATIVE FEATURES

The Alpine A110 E-ternité offers even more, with new equipment developed simultaneously by the Alpine engineers.

A LONG-AWAITED OPEN ROOF

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.

CENTRAL SCREEN & AUDIO SYSTEM

Alpine engineering has made it a priority to develop a vehicle that is as beautiful as it is efficient. The cockpit must therefore reflect this as well. The team succeeded in combining the design requirements with the electronic architecture ones. The solution: the wiring was done directly with the dashboard and the same interface computer was used. The result lives up to expectations and also integrates:

• a state-of-the-art audio system with 8 speakers including a subwoofer to recreate a surrounding sound thanks to one central and two rear new speakers.
• an innovative multimedia system using the driver's personal tablet as the multimedia screen, in order to display the usual environment and apps of the user. This solution provides an always up-to-date operating system combined with the latest screen technologies.

INNOVATIVE MATERIALS

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.
