Back in 2012, Matt Smith swiped former Doctor Who star David Tennant's crown to become the fastest Time Lord to negotiate Top Gear's infamous test track in the show's Reasonably Priced Car. Tonight, on BBC3, you can relive that historic moment...
Smith recorded a time of 1:43.7 in a Kia Cee'd, smashing predecessor Tennant's 1:48.8 set in 2007 in a Chevrolet Lacetti, and ninth Doctor Christopher Eccleston's 1:52.4, recorded in an automatic Suzuki Liana in 2005.
The Eleventh Doctor even beat one-time Who companion Billie Piper, who was half a second faster than Tennant after a controversial run he complained had seen her cutting some corners.
Smith struggled with some turns himself during his practice runs but came good to record the impressive time, keeping calm by humming Singin' in the Rain as he negotiated the course.
