IndyCar fans' six-month wait for the 2021 season to get underway will end this Sunday, Apr. 18, but they'll be watching the action unfold with a feeling of déjà vu. That's because, for the second straight year, the traditional season opener in St. Petersburg was skipped because of COVID-19 concerns.Last season, America’s premier single-seater racing series had to scramble to put together a makeshift schedule. There was just one adjustment this time around: IndyCar moved St. Petersburg to Race No. 2, and the Honda Indy Grand Prix of Alabama at Barber Motorsports Park will run as scheduled.So will the rest of the 17-race calendar.In an interview with @JennaFryer of the AP about his new @CarvanaRacing ad campaign, @JimmieJohnson says he and his wife, Chani, are open to him racing in the Indy 500 next season as he makes the transition to #IndyCar https://t.co/pKjp7VBvtV— IndyCar on NBC (@IndyCaronNBC) April 13, 2021One of the big storylines leading up to the IndyCar opener will be the open-wheel debut of future NASCAR Hall of Famer Jimmie Johnson. The California native will be piloting his familiar No. 48 for Chip Ganassi Racing, but instead of being in a Chevrolet stock car, he will steer a Dallara IR-12 Honda chassis.Johnson, 45, will handle every IndyCar road and street course - 13 in all - while series veteran Tony Kanaan will drive the car on the four ovals. Kanaan will be the oldest and most experienced active IndyCar racer this season. Johnson’s teammate Scott Dixon has made 272 consecutive starts heading into the weekend - the second-longest streak in IndyCar. Kanaan holds the mark at 318, which ended last year.Will Power, Ryan Hunter-Reay, Josef Newgarden, Simon Pagenaud and Takuma Sato are the only entered drivers who have wins at Barber Motorsports Park. Kanaan, Graham Rahal, Dixon, Hunter-Reay and Sato have started every IndyCar race at Barber.Sato won at Barber two seasons ago, which makes him the defending champion since IndyCar canceled the 2020 event due to the pandemic. The Japanese driver also won the NTT P1 Award at 1:08.5934 / 120.711 mphAnticipation continues to build for the season opener Sunday, April 18 @BarberMotorPark.
