Los Angeles - Chris Evans spends just four hours a day filming Top Gear.
The 49-year-old TV presenter - who is said to have signed a three-year deal worth £3m to front the new-look motoring show from May - has revealed he starts shooting scenes for the programme around 10:00 and leaves at 14:00 "on the dot" to pick up his kids.
According to The Sun newspaper, Chris told Top Gear magazine: "I'm useless after 14:00. I'm fried."
The star gets up at 4:45 on weekdays to prepare to host his Radio 2 breakfast show, which airs from 6:30 to 9:30, and then heads to the BBC studios to begin his Top Gear filming duties.
As well as co-hosting the show alongside Friends actor Matt LeBlanc, racing driver Sabine Schmitz, YouTube star Chris Harris, Formula 1 pundit Eddie Jordan, motoring journalist Rory Reid and The Stig, Chris will also help produce the programme.
The former TFI Friday presenter is said to have been in talks over a "hefty production fee" for his additional commitments.
