LeBlanc is a "familiar face" on the show already according to the BBC, having twice been a "star in a reasonably priced car" guest and a presenter of spin-off show Top Gear: The Races.
He said: "As a car nut and a massive fan of Top Gear, I'm honoured and excited to be a part of this iconic show's new chapter. What a thrill."
Evans added: “Matt’s a lifelong fellow petrolhead and I’m thrilled he's joining Top Gear. Acting out our craziest car notions on screen is a dream job and I know we’ll both be debating some epic road trip ideas."
