TG drives the VW XL1 in London

London is smiling. TopGear's home city, bathed in July sun, has got the summer mood. The buildings and streets and views look magnificent, the people have opened their hearts and minds. It's an ideal morning to present them with something utterly fresh. A pearlescent-white streamlined personal transport module that looks like it's been beamed in from a future decade. A VW XL1. And they love it.
