IMSA Petit Le Mans at Road Atlanta: How to watch, start times, schedule, entry list

IMSA Road Atlanta start TV schedule

Start times, TV schedule: The IMSA WeatherTech SportsCar Championship will conclude the 2021 season this weekend at Michelin Road Atlanta as the Motul Petit Le Mans is held under an unusually longer shroud of darkness.

Normally held in late September, pandemic schedule disruptions have pushed the prestigious 10-hour season finale to Nov. 13, which means roughly half of the endurance race will be held at night on a 2.54-mile road course with sparse track lighting.

“The more of the race at night time, the more the chances that contact can happen,” said Filipe Albuquerque of Wayne Taylor Racing. “Going through Sector 1, you dive into that little chicane, and that’s when bad luck happens, that opens more to that contact. You can’t have it. If you’re a a lap down, you’re done. It’s hard to get laps back, and it’s a small lap as well, if you need to come in to replace the nose, you can easily lose a lap. You need to (be) sharp to (avoid) a mistake.”

Albuquerque and co-drivers Ricky Taylor and Alexander Rossi are aiming to be perfect as they try to protect the No. 10 Konica Minolta Acura’s 19-point lead in the DPi standings over the No. 31 Whelen Engineering Cadillac of Action Express with drivers Pipo Derani, Felipe Nasr and Mike Conway.

After teaming with Derani and Nasr last year, Albuquerque moved to WTR in 2021 and drove the final stint of its Rolex 24 at Daytona victory. The team since has added victories at Mid-Ohio and Laguna Seca.

But Derani and Nasr (who is in his final race at Action Express) have won three of the past four races (Long Beach, Road America and Watkins Glen) in the premier class to make it a tight battle.

“The championship comes down to so many moving parts, especially on the long races,” Derani said. “We’re coming down to the final race with the slimmest of margins.”

Adding another layer to the drama is that Derani and Taylor (then racing for Team Penske) collided while racing for the lead with 10 minutes left in last year’s Petit Le Mans.

Rossi, the 2016 Indy 500 winner, is one of several endurance drivers from other series in the field. Seven-time NASCAR Cup Series champion Jimmie Johnson will be making his fourth start this season in the No. 48 Cadillac with 2019 Indy 500 winner and 2016 IndyCar champion Simon Pagenaud and two-time Rolex 24 winner Kamui Kobayashi.

Six-time IndyCar champion Scott Dixon will be teamed with Renger van der Zande and Kevin Magnussen in Chip Ganassi Racing’s No. 01 Cadillac. Four-time Indy 500 winner Helio Castroneves and two-time Indy 500 winner Juan Pablo Montoya will join Dane Cameron on the No. 60 Acura of Meyer Shank Racing.

IndyCar Detroit Grand Prix: How to watch, start times, TV, schedules, streaming


The NTT IndyCar Series will return to the Motor City for the Chevrolet Detroit Grand Prix but with start times in a new location for 2023.

After a 30-year run on Belle Isle, the Detroit GP has moved a few miles south to the streets of downtown on a new nine-turn, 1.645-mile circuit that runs along the Detroit River.

It’s the first time single-seater open-cockpit cars have raced on the streets of Detroit since a CART event on a 2.5-mile downtown layout from 1989-91. Formula One also raced in Detroit from 1982-88.

The reimagined Detroit Grand Prix also will play host to nightly concerts and bring in venders from across the region. Roger Penske predicts the new downtown locale will be bigger for Detroit than when the city played host to the 2006 Super Bowl.
