The NTT IndyCar Series prides itself on showcasing young, exciting talent in addition to a cast of savvy vets. But this week, we only care about showcasing one thing: A bunch of really old dudes on social media.

As the FaceApp Challenge went viral, teams and drivers from across the paddock joined in on the fun. Some results are more scary than others, some are charming and others yet are extremely savage. 

Take Alexander Rossi's post with Helio Castroneves and Ryan Hunter-Reay, for example. Notice that Rossi's face has been magically resurfaced to look old, while Hunter-Reay and Castroneves remain unfiltered and ... maybe not so young? 

"Look, now we're all the same age," Rossi wrote. So, so ruthless. Castroneves didn't hesitate to fire back, though. He may be older than Rossi, but the hair game remains strong.

Points leader Josef Newgarden got in on the fun, too. Turns out, he's a pretty suave old man.

And Jack Harvey is definitely on his way to becoming a university professor in Great Britain. Racer today, charming teacher in a suit 30 years from now.

Santino Ferrucci's current haircut on an old man is a sight to behold.

And, truly, the entire rookie class is a pretty funny group to throw into this experiment. But don't tell Bryan Herta about this response from Michael Andretti.

Last, but certainly not least, is one of the paddock's oldest drivers: Tony Kanaan. He may be 44 years old, but he could probably still beat you up.
