Upcoming Kentucky Test Adds New Variables to Lower-Downforce Equation

For more than a third of active NASCAR Sprint Cup Series drivers, there will be no rest for the weary.

One driver from each Cup organization is eligible to participate in a test of newly repaved Kentucky Speedway on Monday and Tuesday. The test is a continuation of NASCAR’s proving-out process for a new lower-downforce competition package earmarked for 2017.

Last year, as the sanctioning body solidified the rules for 2016, races at Kentucky and Darlington were used as benchmarks for the progression toward lower downforce for the Cup cars. This year, in selected events, NASCAR is taking an additional 500 pounds of downforce and 125 pounds of sideforce away from the cars by chopping the size of the spoiler, reducing the surface area of the splitter, tapering the rear deck lid fin and eliminating rear axle offset.

NASCAR Pleased with Performance of New Aero Package at Michigan

The new lower-downforce aerodynamic package under evaluation for 2017 got its first test in a points race at Michigan, and NASCAR officials liked what they saw in the 400-miler.

“It was definitely different than we’ve seen here before, a lot of action on the restarts, a lot of movement there,” said Scott Miller, NASCAR’s senior vice president of competition. “Obviously, we all watched it get strung out a little bit, which we weren’t hoping for longer into the runs.

“I think we saw a lot of things that we liked, some other things that may need a little bit of reevaluating, but I think overall, for such a big move in downforce, that it was a really pretty successful day and something that we can build on.”

If the new configuration, or a variation thereof, is adopted for next year, Goodyear will have time to build a tire designed for the new package and the track.

“I think we probably need to come back to a bit more work on the tires, which these tires have not been tuned to this package, so we’ll work with our Goodyear folks,” said Gene Stefanyshyn, NASCAR senior vice president, innovation and racing development. “Probably a bit handicapped by the entry speeds being pretty high (reaching roughly 218 mph), so still that creates some aero effects, so that’s something we’ll look at.

“But again, this has been planned as a two to three step process. We’re off to Kentucky tomorrow (for an organizational test on Monday and Tuesday), and then we’ll be on the track at Kentucky (July 9)—shorter track, lower speeds and all that, so we’ll see how that all comes together.”

Dale Earnhardt Jr. Wrecked Early at Michigan International Speedway

Vocal that he had a strong car for Sunday’s FireKeepers Casino 400 at Michigan International Speedway, Dale Earnhardt Jr. never really had the opportunity to showcase it after being eliminated in early race crash.

Shortly after a Lap 60 restart Earnhardt’s Chevrolet was in a three-wide battle with Chris Buescher (on the bottom) and A.J. Allmendinger (on the outside). Buescher’s Front Row Motorsports Ford broke loose and hit the left rear of Earnhardt’s car, which sent both he and Allmendinger into the backstretch wall.

The damage was too severe for both Earnhardt and Allmendinger to continue placing them 39th and 38th respectively in the finishing order. Continue reading

Another Race Goes up in Smoke for Kyle Busch at Michigan

To say 2016 has been a feast-or-famine year for Kyle Busch would be a colossal understatement.

And lately it’s been all famine.

Just past the 50 lap mark of Sunday’s FireKeepers Casino 400 NASCAR Sprint Cup Series race at Michigan International Speedway, the engine in Busch’s No. 18 Joe Gibbs Racing Toyota gave up the ghost, spewing fire from underneath the chassis and filling the driver’s compartment with smoke.

Busch unpinned his window net, drove his car to the garage and exited the race in 40th place, the first driver out.

That marked the fourth straight event in which Busch has finished 30th or worse and the sixth time in 15 races he has run 25th or worse.

On the other hand, Busch has finished in the top four on nine occasions and has three victories to his credit, most in the series so far this year.

“Just been feeling the motor kind of going south for about 30 laps or so and it finally let go,” Busch said of Sunday’s failure. “At least there was plenty of warning, and I knew it was going to get hot in there, and it certainly did once it let go and it was on fire. It’s just been a dismal month, just haven’t been able to hit anything and get good finishes going.

“Our car has been really fast and (crew chief) Adam (Stevens) and the guys have been doing a great job getting us good stuff to the race track, but it just wasn’t our day today… We started out the season good and strong and had some top fives and such, so it was a good foundation for us to build off of. We’d like to be able to get our luck turned around and get back to finishing races where we know we can.”

Credit it to a good car or a lower downforce package, one thing is for sure Tony Stewart was all smiles Sunday afternoon following a season-best seventh place finish in the 48th annual FireKeepers Casino 400.

The Stewart-Haas Racing co-owner and driver qualified a superb third on Friday afternoon and was able to transform the speed into the 200-mile race Sunday afternoon, running as high as third, but eventually finishing seventh. Continue reading
