Mercedes’ motorsports strategy director James Vowles says he was “very impressed” with Valentino Rossi’s “meticulous” approach when driving the W08 in Valencia.

As part of a swap between seven-time MotoGP World Champion Valentino Rossi and six-time Formula 1 World Champion Lewis Hamilton, both icons got the chance to swap into each other’s worlds.

Rossi would be given the chance to drive Mercedes’ 2017 title-winning car, while Hamilton got a taste of one of Rossi’s 2019 Yamahas in Valencia.

It was the Italian’s first F1 test since 2010, but Sky Sports F1 reported that Rossi set a fastest time 1.5s slower than Hamilton’s, although no official times were recorded.
