Grosjean, who scored 10 podiums in his nine-year F1 profession, all for Lotus, immediately accomplished his third and ultimate day of preseason testing for the Dale Coyne Racing with RWR-Honda workforce.
He turned 120 laps of the 1.7-mile brief course at Sebring Worldwide Raceway, sharing the monitor solely with teammate Ed Jones, and Carlin-Chevrolet’s Max Chilton.
Boisson mentioned that Grosjean had made “good progress” since his earlier two one-day exams at Barber Motorsports Park and WeatherTech Raceway Laguna Seca – but additionally acknowledged the steep studying curve that his new driver faces within the NTT IndyCar Sequence, regardless of beginning 180 F1 grands prix.
“This sequence is hard,” Boisson informed Autosport, “and irrespective of who you’re, you’re not going to point out up as a rookie and simply kick individuals’s ass. All people’s aggressive and the tracks are very totally different, it’s a must to be taught so many tips between all these totally different tires and totally different tracks.
“That’s why there are actually good guys of their 40s who’re nonetheless performing rather well. It takes data, understanding and expertise, in addition to reflexes and pace.
“So it’s going to be a giant problem initially, the primary few races, simply due to the character of IndyCar racing. It’s a really aggressive and difficult sequence, as a result of we’ve totally different tires, several types of racing, and little or no observe.”
Boisson, who final 12 months engineered Santino Ferrucci and earlier than that Sebastien Bourdais, mentioned Grosjean has “been within the health club however we acquired him fairly drained by the top of the day. He’s good with the warmth, however immediately was 90degF and fairly humid, in order that’s positively powerful situations.
“However since Barber and Laguna Seca, Romain has discovered what we’ve as instruments for adjusting the automotive, what does he like, what does he not like, so it was instructive, day.
“We did some gasoline saving observe, and since there have been solely three automobiles on monitor we took the chance to observe operating beneath yellow [caution], easy methods to do restarts, that type of factor that he’ll must do in some unspecified time in the future.
“Then, we additionally did loads of adjustments to the automotive immediately: totally different rollcenters, diffs, dampers and did much more than even the final check. The final two exams, we didn’t actually have an opportunity to alter the diff or do an excessive amount of with the rollcenter – or not as aggressive as we needed.
“However since then Romain has been to the simulator so we began engaged on the entire package deal, we tried extra setups. Immediately, we mentioned, ‘OK, let’s apply these issues we discovered [in the sim] and though the automotive is probably not good for Sebring, it doesn’t matter as a result of we don’t race at Sebring. Let’s simply strive stuff, see what it does, learn how it feels.’

“He observed how tough the surfaces might be. After the primary run at Sebring, he got here in and mentioned, ‘Yeah, it’s bumpy’, and I mentioned, ‘And also you haven’t even been to Detroit but!’ It’s positively an eye-opener, how bumpy it’s. It’s important to do some humorous stuff to the automotive.
“However the simulator really does a very good job together with all of the bumps and roughness of those tracks. The road races are actually onerous for a rookie, with no testing on them.
“Sebring represents one thing much like a avenue course for us, but it surely’s not a avenue course per se. A few of the corners are a bit sooner, among the corners are much less bumpy than the road programs we race on. And this 12 months we’re going to have much less observe and that’s going to be onerous – two classes as an alternative of three earlier than qualifying.
“So the Honda simulator helps rather a lot so he can be taught these tracks earlier than we get there, and so we will begin to play somewhat bit with the setup for him.”
Boisson mentioned that Grosjean has discovered the adjustability parameters of the automotive, and is now adapting his fashion to the automotive, somewhat than attempting in useless to make the automotive swimsuit his pure fashion.
“Yeah, he’s positively adapting himself; he’s a hard-working, devoted man,” mentioned Boisson. “He’s been learning knowledge so much.
“Barber was onerous as a result of it was his first time, it’s a troublesome monitor and we weren’t superb there. However by the point we acquired to Laguna we appeared much more aggressive as a result of he had been in a position to sit down and take a look at the info and seen, ‘OK, these guys are doing that, I’m not doing that so I should be doing it flawed, so I have to determine that out.’
“He’s positively attempting onerous easy methods to cope with this automotive as a result of within the high-speed corners, this automotive strikes round much more than F1, so he must get snug with the motions. And he’s spent loads of time learning movies and knowledge to adapt himself by understanding what the automotive wants, not what the automotive must do for him.”
Requested how he felt Grosjean’s method in contrast with Ferrucci, Bourdais and Alex Palou, who as a rookie final 12 months raced for Coyne, Boisson mentioned that he was “very related” to Bourdais and Palou.
“Santino was extra like a ‘really feel’ man – goes very onerous and works from his really feel of the automotive,” he replied. “Alex was similar to Seb – very hard-working, going via all the things, analyzing all the things, and what they need from a automotive was very related. And Romain may be very in step with that: he positively does loads of learning, appears on the knowledge so much, all the time desires to speak about it. Seb was like that, Alex was like that.
“And to date, I really feel like what we did with Alex final 12 months [setup-wise] falls fairly effectively with Romain. Santino was OK with so much much less rear-end safety. Romain just isn’t as choosy as Seb [in that area], however extra like Alex, someplace in between Santino and Seb.”

Boisson says that Grosjean just isn’t solely working onerous at enhancing himself, he’s additionally in a position to ship loads of helpful suggestions to the engineering workforce.
“Romain has acquired very detailed rationalization of what’s occurring within the automotive, and that’s essential for me at this level, to know what he means,” he mentioned. “He feels issues very effectively, he’s very detail-oriented and he then provides good suggestions of what he’s feeling.
“And now he is aware of what the restrict of the automotive is and what the instruments can do, he’s attending to the purpose the place he can inform you what he desires.
“However nonetheless, it’s so much for him to soak up. In someday at Sebring, it’s very simple to get confused. I’ve had that many instances at Sebring the place you allow the monitor scratching your head, considering, ‘What is occurring right here?!’ however then you definately go on to St. Pete and suppose, ‘Huh, OK, we weren’t that misplaced.’
“He and Ed [Jones] have related sufficient driving types that they are often helpful for one another this 12 months – it’s very related stuff that they like, after which once we strive it, they offer very related really feel and suggestions. Immediately they diverged somewhat extra, however possibly that was what we have been saying about Sebring – it will probably simply be somewhat unusual. I believe early on within the season, the setups for Romain and Ed will begin off fairly related.”
Though that was the final time Grosjean drives an IndyCar earlier than the opening spherical at Barber Motorsports Park on April 16-18, the #51 DCR-Honda will probably be in motion at Texas Motor Speedway on Wednesday, with Grosjean’s oval sub Pietro Fittipaldi on the wheel.
