Rolls-Royce is launching this ‘experimental’ electric version of its Phantom at the Geneva show — but the car’s specs already look realistic enough to make production a closer prospect than Rolls will officially admit.
The 102EX concept is based on a regular-length Phantom but replaces that car’s twin-turbo V12 with two electric motors that power the back axle through a single-speed transmission.
Together they produce 389bhp, compared with the petrol car’s 453bhp. But they also offer 590lb ft across what Rolls-Royce calls “a wide range”, well clear of the petrol Phantom’s 531lb ft.
These reserves help the 102EX to reach 60mph in “under eight seconds” and an electronically limited top speed of 100mph — even though the car weighs around 200kg more than a regular Phantom, at 2700kg.
Rolls believes the 102EX’s lithium ion battery pack could be the largest yet fitted to a road car. It comprises five modules of 38, 36, 10, eight and four cells, arranged in an irregular-shaped unit that roughly matches the dimensions of the regular car’s engine and gearbox.
