The BBC announced on Tuesday that a new host has been chosen to replace Jeremy Clarkson on the hit auto show Top Gear — British TV and radio personality Chris Evans. The 49-year-old car lover signed a three-year deal as the lead presenter of an all-new line-up for the show, after Clarkson was fired for assaulting a producer. But while Clarkson and his former co-hosts Richard Hammond and James May have built up a devoted fanbase around the globe — Top Gear is watched by a staggering 350 million viewers worldwide — Evans is relatively unknown outside the U.K.
