"With the announcement of Romain Grosjean joining the series… Jimmie Johnson too and we've obviously got Scotty Dixon who's the greatest of all time in Indycar, it's going to be a tough ask and I've got a lot of learning to do but I'm looking forward to the challenge, it's going to be a lot of fun."
McLaughlin is driving the No 3 Dallara-Chevrolet for Team Penske and is being mentored by four-time Indy500 champion Rick Mears.
"He's helping me a lot and he's a legend in motorsport, so to have him in my corner and pushing me to no end, I count myself very lucky.
"He's been great just pretty much bringing my head down to the ground a little bit and calming me down in times that I need it, but at the same time pumping me up when I need it and telling me that things are going pretty good, so it's a nice healthy balance."
Tackling how an Indycar runs compared to a Supercar is McLaughlin's main focus until his first race on April 18 in Alabama.
"The trust of how much grip the car actually has, there's so much power, there's about 850 horsepower in a car that weighs half of a Supercar, so the power to weight ratio is just unbelievable. Big downforce and not only that, the competition between the teams is so tight.
"It's going to be one of those deals where once you get it right it's going to feel really good and you'll be able to feel pretty proud about yourself."
After racing in Alabama, he will then travel to Florida to race, and then straight to Texas, all over the course of three weeks – a very busy start to the year.
