'Top Gear' host Chris Evans is leaving the show after just one series. Evans tweeted: "Stepping down from 'Top Gear'. Gave it my best shot but sometimes that's not enough.
"I feel like my standing aside is the single best thing I can now do to help the cause."
The show failed to hit Evans' own expectations, with viewing figures falling to an average of 1.9 million viewers on Sunday night.
The show isn't seeking an immediate replacement. Rather, co-hosts Matt LeBlanc, Rory Reid, Chris Harris, Sabine Schmitz and Eddie Jordan will return, with LeBlanc widely expected to take on the main host's duties.
The next series starts filming in September.
In a statement released via the BBC, Evans said: "I have never worked with a more committed and driven team than the team I have worked with over the last 12 months. I remain a huge fan of the show, always have been, always will be."
Evans took the reins of the motoring show following Jeremy Clarkson's departure after he punched a producer in a row over food. Clarkson, Hammond and May will film the first episode of their new show, 'The Grand Tour', for Amazon Prime Video in a couple of weeks.
