"It's fun and really rewarding if you get it right," Bird said after finishing the first practice session of Season 9 in 12th place.
"It's super tricky, and the track is very dusty, but the power is a big hike in performance compared to what we're used to. Obviously, last year, we ran at 250kW. Now we've got 350kW. That means big speeds in a straight line. And when you out-break yourself, it's more difficult.

"All of all of us in this pit lane are used to fast cars. So it's not out of our comfort zone for us to be going this quick in a straight line."
There's no doubt that Bird will be hoping this is the season he can finally clinch the Drivers' World Championship after coming so close on several occasions. However, both Bird, and his Jaguar teammate, Mitch Evans, will be desperate to get their hands on a first Formula E title before the other one does.
So, after some testing and a practice session under his belt, what does Bird expect to be the biggest challenge with these Gen3 machines?
"The thing that is more difficult this year is just how much software there is in these cars. It's a really intricate piece of kit. Getting all the software in the right window is fundamental to being quick. If one thing's out the window, the whole car feels completely out.
"We've had communication issues on my car with some software. I wasn't quite happy with things, and it really makes the session a lot harder.
"If everything's in a window, I think the car would be absolutely fantastic. We've just got to do a couple of little tweaks, and I think we could be there."
Bird managed to secure a podium at Mexico City back in Season 3, but since then, his results around the Autodromo Hermanos Rodriguez have been relatively disappointing. Will a new refresh of the rules be what the Jaguar driver needs to find himself on the top step once again?
