BBC motoring writer Jorn Madslien is one of the first people outside Rolls-Royce to have driven the company's newly built electric car. So, is it any good?
The silence is, if not deafening, than at least spine-tingling as the 2.7 tonne Rolls-Royce Phantom effortlessly takes off down the drive of the carmaker's Goodwood factory.
The only sound is a slight tyre noise, and even that is barely audible inside the luxury car's insulated cabin.

For Autobahn warriors, the electric Rolls-Royce may even come across as slow, what with its top speed capped electronically at 100 miles per hour (160 kilometres per hour) - though it accelerates from nought to 60mph in about eight seconds.
Some might also grumble about the car's limited range - estimated at about 125 miles on one charge of the biggest battery yet to be fitted in an electric car.
