Rossi has previously tested a number of Ferrari models, and his latest go in an F1 car came as part of a ride-swap event that saw Hamilton trial his Yamaha MotoGP bike.
It is reported that Hamilton spun the Silver Arrow thee times in his demo run, while Hamilton also admitted to a minor error while he was on two wheels.
But ‘The Doctor’ was certainly impressed by the W08, highlighting its speed above anything else.
“I have tried an F1 car before, but much has changed since then,” Rossi said.
“Sincerely, I was impressed with the car and its handling, as well as with the Mercedes-AMG Petronas Motorsport team, who were great to work with. They were very welcoming and made it easy for me to get familiar with the car.
“At first you get an amazing sensation of speed. The G-forces were not so bad, but it takes some getting used to. Once I got into the rhythm I could really push. It was a great pleasure.
“I really enjoyed sharing this experience with [Lewis], and I think he had loads of fun too, demonstrated by how reluctant he was to stop riding!
“I sincerely hope we will get to have many more experiences like this in the future.”
