Rolls-Royce 102EX -
Phantom Experimental Electric Car
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gearbox have been replaced by a lithium ion battery pack and two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
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.
This is the first application of the technology in a GKL++ segment
(super luxury vehicles priced at more than €200,000) and the battery
pack is thought to be the largest ever fitted to a road car.
Evaluation of technology is an important part of the test programme.
However, more fundamentally the car will seek answers to questions
posed of Rolls-Royce owners: what their needs might be for the
future considering factors such as range, performance and
The feedback from customers – as well as media, stakeholders and
enthusiasts via the website www.electricluxury.com - will prove
essential in evaluating the appropriateness of battery electric
technology for Rolls-Royce.
It will help inform a decision on whether all-electric, or another
alternative drive-train technology, will be most appropriate for the
world’s best cars of the future.
