Former McLaren F1 team-mates Hakkinen and Coulthard joined Rovanpera’s Toyota team for a pre-event test in Sardinia.
At the test, Hakkinen and Coulthard both climbed aboard the current WRC specification Toyota GR Yaris alongside Rovanpera for a blast through Sardinia’s rough gravel roads in a special feature for sponsor Unibet.
The 22-year-old admitted he enjoyed frightening the ex-F1 drivers with his skills behind the wheel.
"Yeah, it was super cool. Together with Unibet we had this project and they were let’s say quite scared and excited to be in the car," Rovanpera told Autosport.
“It is quite different for circuit drivers to be in a rally car but that was their honest reaction, so it was funny for me and we have some more stuff to do with them that is coming which is cool also.”
Both Hakkinen and Coulthard were left visibly stunned by the experience.
“That was an unbelievable experience. I’m not sure I would call it fun but it was like an out-of-reality experience with consequences,” said Coulthard.
“It was just the commitment in the high-speed corners.”
