It’s a big day for birthdays in the IndyCar paddock.
Racing icon Mario Andretti (pictured) — still the only driver to win the Indianapolis 500, Daytona 500 and Formula One World Championship — is turning 73 years old today.
In addition, four-time Champ Car World Series champion and current Dragon Racing pilot Sebastien Bourdais is also celebrating a birthday, turning 34. And it looks like Bourdais has already received a present of sorts from Andretti this morning.
Be sure to send your birthday wishes today to two great drivers from two different generations. You can follow Mario on Twitter at @MarioAndretti, and also Bourdais at @BourdaisOnTrack.
