Richard Hammond has revealed the Top Gear trio are "charged" about "evolving and reinventing" their former show for Amazon Prime.
Hammond, along with Jeremy Clarkson and James May left the BBC earlier this year, and signed a "very, very, very expensive" deal to make a car-themed programme with Amazon Prime in July.
Speaking to ITV's This Morning presenters Phillip Schofield and Holly Willoughby, the 45-year-old said: "The point is, an amazing opportunity has come along for us to evolve and reinvent what we do, and we're all just charged. It's kind of wonderful, at our stage in life and career, we've got the opportunity to do exactly that when otherwise, let's be honest, you might not.
"But having to do that - really the truth of it is, it's not so much that I won't talk about it. We're still heads down, working on stuff."
Hammond and May decided to join Clarkson in leaving the BBC, after the outspoken Clarkson's contract was not renewed, following a "fracas" with Top Gear producer Oisin Tymon.
Hammond - whose next small-screen outing is in Sky1 documentary Richard Hammond's Jungle Quest - hinted the new motoring show will see the trio as innovative as ever.
He explained: "What we made before was expensive, the main value in TV generally is ideas, and what a brilliant time to be making a show about cars on television, because the automotive industry is undergoing tremendous change.
"We will find alternative propulsion forms - we have to. And television itself likewise is undergoing a huge sea change. So to be reporting on a changing industry from within a changing industry is a massive challenge."
Hammond, Clarkson and May's new as-yet-untitled show is scheduled to start airing on Amazon Prime in 2016.
Meanwhile, Chris Evans will take over hosting duties on BBC's Top Gear.
