Rolls-Royce 102EX must be the first real, big, solid and stylish limousine class electric car. Engineers created the 102EX concept based on their legendary Phantom model to test how potential customer will react to an electric-powered limousine and it will be test-driven on selected regions only. The red RR letters and EX addition to the model's name has been known to mark experimental Rolls-Royce cars since 1919 and Rolls-Royce 102EX electric limousine is by far the most experimental model from the well known British limousine manufacturer.
Rolls Royce 102EX, also called the Rolls-Royce Phantom Experimental Electric or simply Phantom EE has a single speed transmission with integrated differential and is powered by two electric engines producing 194 horse power each, which in total provides a 388hp (290kW) power with 590ft/lb (800Nm) torque from the first till the last seconds you press the acceleration pedal. There is no big difference compared to the standard Phantom limousine which is powered by the 453hp (338kW) engine pulling the car with 531lb/ft (720Nm) at 3500rmp. Electric installation and, mainly, battery pack adds additional 200lb to the Rolls-Royce Phantom EE and it weights 5996lbs (2720kg), but still can reach 100 km/h in an astonishing 8.0 seconds which is 2.3 seconds slower compared to petrol powered Rolls-Royce limousine. Unfortunately, top speed is limited to 100mph.
The battery pack is said to be the largest one in the passenger car - it contains a total of 96 Lithium-Nickel-Cobalt-Manganese-Oxide cells packed in five groups and arranged to match the shape of 6.75L V12 petrol engine and six-speed automatic gearbox in the non-electric Rolls-Royce Phantom. With a 102EX you will be able to drive around 120 miles, and recharging, Rolls-Royce claims, will take around 20 hours from a standard outlet with a single phase or around 8 hours if you connect Phantom Experimental Electric to a three phase power. To push innovations even further Rolls Royce added an induction charger which enables wireless charging and is a new technology allowing electric cars to be charged without physically connecting them to a power outlet.
