Romain Grosjean has admitted surprise at some of the technical aspects of Mercedes' 2024 car.
Grosjean has been an IndyCar driver since leaving F1 in 2020, having spent the best part of a decade sharing the paddock with Lewis Hamilton and co.
He achieved multiple podiums with Lotus-Renault before a move to Haas where he would finish his career.
He also raced through every season that Mercedes took both titles during the turbo-hybrid era, and their latest tricks have the Frenchman intrigued ahead of the first race of the year.
Speaking on his YouTube channel about the field ahead of the new season, Grosjean earmarked the Mercedes as one he is excited to see hit the track in anger.
“I think it is the car, with the Red Bull, I’m the most intrigued to see on track,” he said.
“I think there’s some very bold moves. There are some very bold decisions made on the car. Look at that front wing and that big scoop.
“It does remind me a lot of the 2006 F1 cars that I used to be in love with… and then those sidepods. They went for a very small entry to get as much flow as they can under the sidepods.”
Their performance at the pre-season test wasn’t headline making, but it looks like they will be in contention to compete later this year for the odd win if they continue this line of development.
They only have 24 more races with Hamilton and will be aiming to make the most of the remaining time with their star driver.
