This one-off campaign for the electronics giant, which was planned and booked by ipm and Cheil, is expected to reach more than 5.2 million adults over the three months that the SuperLivery is live, delivering 93% coverage of the capital's audience.
The new format uses transparent graphics to extend the canvas of a traditional taxi livery to include the two passenger side windows.
It is one of the first new taxi advertising formats in London since Ubiquitous launched its FlexiSide offering four years ago, and it will undergo an "on the road" assessment by TfL, following which it is anticipated that the SuperLivery will be approved as a taxi format for London.
John Mason, director of London Taxi and Private Hire, said: "TfL is always happy to work with companies such as Ubiquitous where there appears to be a good opportunity to increase income for cabbies through advertising on their vehicle.
"We will work closely with all parties during the pilot and look forward to hearing how passengers, drivers and advertisers respond to this type of advertising on our world famous London taxis."
Andrew Barnett, Ubiquitous managing director, said: "We're especially delighted to be launching this media first campaign with a much-valued client, Samsung."
