Rolls-Royce 102EX

The Rolls-Royce 102EX, also known as the Phantom Experimental Electric (EE), is a one-off electric prototype version of the Rolls-Royce Phantom VII. It was created by Rolls-Royce to gauge the response of customers and other stakeholders to an electric Rolls-Royce.

The 102EX was revealed at the 2011 Geneva Motor Show.[1]

Specifications

The 102EX is powered by two UQM-supplied[2] synchronous permanent-magnet electric motors mounted on the rear sub-frame.[3] Each of these motors are power rated to 145 kW for a maximum system output of 290 kW (389 hp).[1] Maximum torque output is 800 N⋅m (590 lb⋅ft).[1] Power is transmitted to the rear wheels by a 1-speed Xtrac transmission with integrated differential.[4]

These motors are fed by a 71 kWh battery pack which is composed of 96 NCM[note 1] cells.[1] These cells are placed in the space occupied by a standard Phantom's engine and gearbox. Peak battery current is 850 amperes delivered at 338 volts (DC).[1] The cells were manufactured by Dow Kokam,[5][6] which Scottish firm Axeon assembled into a battery pack.[5] Electric drivetrain integration was carried out by Lotus Engineering.[7]

The battery pack is charged by 3 separate 3 kW charger units which allow for a minimum charging time of approximately 8 hours.[1] Alternatively, the Phantom is also fitted with an induction charger which allows the car to be charged wirelessly.[1]

The 102EX is differentiated from series production Phantoms visually. It is painted in "Atlantic Chrome" silver which uses ceramic nano-particles to increase the reflectivity of the paint.[1] It is fitted with red "double-R" badges, which Rolls-Royce uses to denote its experimental vehicles.[1] The Spirit of Ecstasy is made of Makrolon polycarbonate and is illuminated by blue LED light.[1] The fuel filler cap features a glass window, allowing one to see the five-pin socket used to charge the 102EX. The interior and luggage compartment use "Corinova" leather. This is a type of leather that is vegetable tanned, as opposed to chrome tanned like ordinary Phantom leather.

Reception

The Phantom was well-received by automotive journalists.[3][4][5][8][9][10][11] Reviewers praised the exceptional refinement afforded by the 102EX's quiet powertrain, while some also felt that ride quality had been improved over the standard Phantom.

Rolls-Royce revealed in 2012 that customer reaction to the 102EX had been lukewarm.[12][13][14] While the 102EX's refinement had been praised, customers took issue with the car's limited range and long charging times.[12][13] Some also felt that the absence of a V12 detracted from the car's specialness.[13]
