Dale Earnhardt Jr. ponders a 24-hour NASCAR race

10 Comments

Dale Earnhardt Jr. is a big fan of the Rolex 24 at Daytona. He’s competed before, including in the 2001 event with his father Dale Earnhardt Sr.

So as this year’s edition of the Rolex 24 closed in on the finish Sunday, Junior went on Twitter to recall some of his past exploits in the road racing event, including posting several photos of cars he has driven in the annual sports car race at Daytona International Speedway.

So, after taking a walk down Memory Lane, Earnhardt posed an interesting question to his Twitter followers:

That actually is a great question. But could NASCAR Sprint Cup cars really — especially mechanically — run a full 24 hours, even if there were switches of drivers behind the wheel? Would the 750-horsepower, 3,600 pound cars be able to run on a track for so long.

Plus, would a proposed race be run on a road course or a typical NASCAR oval?

That’s where things get a little interesting mathematically.

Using a 1.5-mile oval like Charlotte Motor Speedway as an example, think about it: Since most 500-mile NASCAR races are typically contested in around four hours — give or take — if NASCAR were to seriously consider a 24-hour event, that would mean the race itself would last 3,000 miles!

And, that would mean something like, oh, maybe 44 pit stops!

I know there are fans who like to say they want longer rather than shorter races, but 3,000 miles in total? I question even the heartiest NASCAR fans would want to watch a race that long.

I also have to wonder how many folks would still be watching, let alone still be awake, when a Cup 3,000-miler would finally be completed.

Starting lineup grid for IMSA Petit Le Mans: Tom Blomqvist puts MSR on pole position

IMSA WeatherTech SportsCar championship contender Tom Blomqvist put the Meyer Shank Racing Acura at the front of the starting lineup for the Motul Petit Le Mans at Michelin Road Atlanta.

Blomqvist turned a 1-minute, 8.55-second lap on the 2.54-mile circuit Friday to capture his third pole position for MSR this season. Earl Bamber qualified second in the No. 02 Cadillac for Chip Ganassi Racing.

Ricky Taylor was third in the No. 10 Acura of Wayne Taylor Racing, which enters Saturday’s season finale with a 19-point lead over the No. 60 of Blomqvist and Oliver Jarvis (who will be joined by Helio Castroneves) for the 10-hour race.

With the pole, MSR sliced the deficit to 14 points behind WTR, which will field the trio of Taylor, Filipe Albuquerque and Brendon Hartley in Saturday’s race.

“We really needed to put the car in this kind of position,” Blomqvist said. “It makes our life a little less stressful tomorrow. It would have given the No. 10 a bit more breathing space. It’s going to be a proper dogfight tomorrow. The guys gave me such a great car. It’s been fantastic this week so far, and it really came alive. I’m hugely thankful to the boys and girls at MSR for giving me the wagon today to execute my job.

“That was a big effort from me. I knew how important it was. It’s just awesome for the guys to give them some sort of reward as well. It’s always nice to be quick. If you do the pole, you know you’ve got a quick car.”

Though WTR has a series-leading four victories with the No. 10, MSR won the Rolex 24 at Daytona and has five runner-up finishes along with its three poles.

The strong performances of the ARX-05s ensure that an Acura will win the final championship in IMSA’s premier Daytona Prototype international (DPi) division, which is being rebranded as Grand Touring Prototype in the move to LMDh cars next season.

Taylor qualified third despite sliding into the Turn 5 gravel during the closing minutes of qualifying while pushing to gain points.

“Qualifying was important for points,” Taylor said. “Going into it, if we outqualified the No. 60 Meyer Shank Acura, they had a lot to lose in terms of championship points. So, we were trying to increase the gap over 20 points which would’ve made a big difference for tomorrow. We would have loved to get the pole and qualify ahead of the No. 60, but in the scheme of the points, it didn’t change a whole lot. I’m feeling good since it’s such a long race, and the No. 10 Konica Minolta Acura team does such a good job strategizing and putting us in a good position.

“I’m very confident in our lineup and our team compared to them over the course of 10 hours. I’d put my two teammates up against those guys any day. I think we are all feeling optimistic and strong for tomorrow.”

In other divisions, PR1 Mathiasen Motorsports (LMP2), Riley Motorsports (LMP3), VasserSullivan (GTD Pro) and Paul Miller Racing (GTD) captured pole positions.

The broadcast of the 10-hour race will begin Saturday at 12:10 p.m. ET on NBC, moving at 3 p.m. to USA Network.
