This is the electrified version of the E-Type, driven in prototype form but set to be offered by Jaguar Classic alongside the restored 'Reborn' versions of the iconic sports car that it already sells.
The production versions will have some detail differences, but we're told that the concept — experienced briefly during Monterey Car Week in the US — offers a pretty much identical experience.
Intriguingly, the use of an electric powertrain that shares its dimensions with the E-Type's original six-cylinder engine and gearbox means it will ultimately be possible to electrify other cars that were powered by the classic 'XK' engine.
The 40kWh battery pack uses the same modules as the Range Rover P400e plug-in hybrid, but has twice as many of them, as well as a higher energy density. This occupies the space formerly occupied by the engine and drives a 190kW motor that sits where the E-Type's original four-speed gearbox used to, driving the rear wheels through a single-speed reduction gear and the original differential.
The modular unit requires no changes to be made to the E-Type's core structure and Jaguar is even offering buyers the chance to save the original powertrain in case they ever want to swap back. It also means that the electric E-Type can continue to use the same suspension and brake components as the donor car; the total weight of the electric powertrain being less than 300kg, slightly under the mass of the original engine and gearbox.
There have been other changes, of course. Control electronics are located under the boot floor in the space previously occupied by the spare wheel. A charging port sits under the original fuel filling flap, although Jaguar Classic's team say they are considering moving this forward for production versions, with most charging infrastructure designed for plugging cars in at the front.
