A month ago, it was Scott Dixon and James Hinchcliffe taking to Texas Motor Speedway to trial the new and revised 2018 aerokits for Honda.
This Wednesday, it was reigning champion Josef Newgarden along with the Ed Carpenter duo of Ed Carpenter and Spencer Pigot who got to trial the new aerokits, this time for their own engine manufacturer, Chevrolet.
The new kits, which at the very least present a striking new image for the premiere American open wheel series, promise to provide an increase in competitiveness, reducing wash off the cars and allowing for closer running between competitors.
Newgarden, returning to drive with Team Penske for 2018 praised the looks of the new kits.
"Everything getting lower, the sidepods getting pushed forward... Those are the big aesthetic differences we really wanted. There is more crash structure in the way of the driver with the sidepods coming forward, but it looks more like an open wheel car."
He also expanded on the feeling of driving the new kits. "I wouldn't say drastically different from a feel standpoint," he said, "This type of an oval (Texas) will be less change than some of the other tracks with aero configurations. There's a small difference just running alone."
Clearly we wont know how the cars run in dirty air until they are able to run in the packs that they are prone to do in Texas. But from all indications, the 2018 season will be one that is sure to watch.
