Many of you are wondering how Sunday’s racing telecasts fared, including whether IndyCar outperformed Formula 1 in the telecasts of each series’ respective season-opening races.

Well, the numbers are in and IndyCar ended up trailing its F1 counterparts—although it was close—as well as NASCAR, which was the weekend’s overall big winner both in motorsports as well. The NASCAR Cup race at Las Vegas won the entire sports weekend, even topping the NBA, NHL and the PGA.

According to ShowBuzzDaily.com, one of the premier sports ratings websites in the business, here’s how the weekend played out for all motorsports:

1) Sunday’s NASCAR Cup race at Las Vegas Motor Speedway was a case of good news and bad news for NASCAR. The good news is the stock car series drew 3.991 million viewers in the Fox Sports telecast from Las Vegas.

However, NASCAR’s Vegas viewership number was also somewhat concerning: Sunday’s ratings were approximately 14% lower than last year’s race, which drew an overall viewership of 4.544 million.

2) With its Sunday morning (10 a.m. ET) ESPN telecast of the 2023 season opener from Bahrain in the Middle East, Formula 1 drew 1.318 million viewers.

3) IndyCar came close to topping F1, but alas, the season-opening race in St. Petersburg, Florida (noon ET) drew a combined NBC Sports/Peacock streaming rating of 1.189 million viewers.

Elsewhere on the racing landscape:

4) NASCAR Xfinity Series race Saturday afternoon (FS1): 1.133 million, up from last year’s viewership of 1,055 million.

5) NASCAR Truck Series race (Friday, March 3, in the evening) (FS1): 623,000, up from last year’s viewership of 543,000.

6) NASCAR Cup qualifying (Saturday, March 4 in mid-afternoon) (FS1): 456,000, down from last year’s 496,000.

7) NASCAR Xfinity qualifying (Friday, March 3, in the early evening) (FS1): 274,000, down from last year’s 302,000.

8) NASCAR Trucks qualifying (Friday, March 3, late afternoon) (FS1): 201,000.

9) F1 second practice mid-morning (Friday, March 3, 9:55 a.m. ET) (ESPN2): 189,000.

10) F1 practice early morning (6:25 a.m. ET) Friday (ESPN2): 126,000.

We'll be following the numbers, but the early returns show that NASCAR is still king in the U.S., while F1 is on the rise and IndyCar has some work to do.
