Newey has been a pivotal figure at the reigning constructors' champions, helping deliver 13 world titles over two dominant spells.
Developing championship-winning vehicles for the likes of Sebastian Vettel and Max Verstappen, the Brit has firmly established himself as the greatest designer in the sport's history.
With his future now seemingly secure, Newey could afford to relax as he took part in this weekend's Goodwood Revival Festival.
The 65-year-old got behind the wheel of two iconic cars at the annual motorsport celebration, but found the going tough.
Competing for the Whitsun Trophy in the Ford GT40, Newey aquaplaned and was left powerless to prevent his vehicle from finding the gravel trap in an uncharacteristic wobble.
It was an unfortunate end to his trophy bid, having previously demonstrated his prowess earlier in the race with a flawless overtake over one of his rivals.
