Rolls-Royce 102EX - Phantom Experimental Electric

an Electric Roller??????????? nah! it cant be???

Reinvention is part of being timeless and Phantom EE is the latest in a line of experimental vehicles from Rolls-Royce Motor Cars. It builds on a legacy which dates back to 1919 and 1EX.

Experimental models are used to test and evaluate new technologies and applications which could shape future Rolls-Royce products. Unlike a concept car, Rolls-Royce experimental models are always fully functioning, drivable vehicles using tangible materials such as wood, leather and metals rather than clay and foam or other concepts.

They present engineers and designers with the opportunity for real-world innovation and are used not only to showcase new components and engineering techniques but also to evaluate them.

The latest in this line of experimental projects began with a Rolls-Royce Phantom, a strikingly modern and immaculately proportioned car in which high technology and hand-craftsmanship combine to produce something extraordinary.

Phantom EE features the car’s ground-breaking aluminium spaceframe, so important to dynamic prowess, as well as the sense of calm and tranquillity enjoyed by occupants. However, the naturally aspirated 6.75-litre V12 petrol engine and 6-speed gearbox have been replaced by a lithium ion battery pack and two electric motors mounted on the rear sub-frame. These motors are connected to a single speed transmission with integrated differential.

Each motor is power rated to 145kW, giving Phantom EE a maximum power output of 290kW and torque of 800Nm available over a wide band. This compares with 338kW for standard Phantom with maximum torque of 720Nm, delivered at 3,500rpm.

The Nickel Cobalt Manganese battery chemistry holds around 230Wh/kg,a high energy density which is important in achieving an acceptable range between re-charges. Pre-launch tests suggests Phantom EE should run to a range of up to 200km. Delivered on an effortless wave of torque, 0-60mph will be achieved in under eight seconds (5.7 seconds in standard Phantom), with top speed limited to 160kph.
