Known around the world for their successful television show 'Top Gear', Jeremy Clarkson, Richard Hammond and James May are moving into the online world. The three presenters have been joined by Ernesto Schmitt, formerly of digital marketing firm Beamly, in creating a new online community for petrol heads called DriveTribe, which is expected to launch in the autumn. The site and dedicated app will launch with a system that will target different car communities, from classic-car enthusiasts to supercar fans. They're looking to target the 428 million declared petrolheads on Facebook for the time being, but also say that they aim to extend the model into other verticals, which could also include fashion or food.
