The Red Bull Soapbox Race is back this year after a nine-year break, and Londoner Carl White is hoping to make a mark with his yellow submarine design.
Today Carl was test driving the car around some of London's most famous landmarks, including Westminster and Abbey Road.
Other vehicles taking part in the event at the capital's Alexandra Palace venue will include a soapbox-sized loaf of bread and, in a nod to Elvis Presley, a replica of a blue suede shoe.
Tickets for the event on July 14 are available now from www.redbullsoapboxrace.co.uk
