Based on the same chassis as the current production car, the E-ternité uses battery packs from the Renault Mégane E-Tech – whose CMF-EV platform will underpin Alpine’s own upcoming electric crossover – but houses them in bespoke casings and spreads them around the chassis for optimum weight distribution: there are four at the front and eight at the rear – in a bid to maintain the A110’s characteristic mid-engined handling behaviour.

The cells weigh 392kg, but Alpine claims to have increased the prototype’s kerb weight by a total of only 258kg – putting the E-ternité at 1378kg at the kerb. If the eventual A110 EV comes in at somewhere around that point, it could be one of the lightest series-production EVs on sale. That’s not only good news for its handling characteristics, but also its efficiency: Alpine claims a range of 261 miles per charge.

Performance-wise, the prototype is a close match for the combustion car on which it is based. It packs 239bhp and 221lb ft from a single rear-mounted motor for a 0-62mph time of 4.5sec and a top speed of 155mph. 

“No gearbox was available in-house” to suit Alpine’s performance aspirations, so it has worked with supplier Getrag to adapt the petrol A110’s dual-clutch automatic ’box for the new electric powertrain. It says this arrangement “makes it possible to avoid a break in torque while remaining compact and light”.
