Chevy exec discusses development of latest low-downforce package

Leave a comment

Yesterday, NASCAR announced further downforce reduction changes for the Sprint Cup Series that will be used for the June race at Michigan International Speedway and in July at Kentucky Speedway.

The changes include:

  • A reduced spoiler that will be 2.5 inches high and 53 inches wide. The current spoiler is 3.5 inches high. The width is the same as the width of a spoiler for superspeedway events.
  • A tapered deck lid fin
  • Neutral rear toe/skew setting
  • 2-inch wide splitter with current center section length.

Chevrolet has conducted a Q&A with Pat Suhy, Chevrolet Racing’s NASCAR Group Manager to answer questions about the package that could be utilized in 2017 and give insight into how the package was developed and tested last week at Michigan.

Q: HOW DID THE NEW TWEAKS TO THE RULES PACKAGE COME ABOUT?

PAT SUHY: “I really think it started in discussions between the teams and NASCAR about where the teams are spending their resources; and wondering if this is really an area they want to race in? NASCAR knows that over time, teams have gained aero performance, whether it’s increased downforce or reduced drag, as they spend more and more time in the Wind Tunnel and as they have worked on the tires to have more grip and more give-up. Gaining back more of the downforce they lost by whatever means, jeopardizes all the work that has been done and fans could see racing return to what it was like last year. I think as a problem to solve it was the question of, ‘Well, where are you guys gaining downforce? How come the cars have all this skew in them?’

“I think there were other discussions going on about electrical loads and battery life and stuff like that. You come to realize that the two things that were just done, reducing the number of fans underneath the car and reducing the skew in the rear of the car, were two of the areas the teams had been working in to gain back a lot of the performance that the body change was supposed to eliminate. Collectively, I think the teams and NASCAR agreed that limiting those things wouldn’t be a bad way to slow the progress down that path and allow them to focus their resources elsewhere.”

Q: HOW WILL THE NEW AERODYNAMIC CHANGES AFFECT HOW THE CARS DRIVE?

SUHY: “The low downforce package that was tested at Michigan last week fundamentally probably won’t change things a lot as far as the way the cars handle. I believe NASCAR and the teams that participated with them on the project directly did a really good job of doing things that were sensible to maintain the aero balance and be simple to implement. The aero balance really didn’t shift very much from where it is today.

“What is going to probably change is the way the cars behave in traffic. Based on what we saw at Michigan, we are going to see corner entry speeds go up, and mid-corner speeds go down. It’s going to put a lot of the ‘driver’ back in the car. It is partway back to the package we saw last spring at Michigan when they tested the 2015 low downforce package there. The speeds were still too high, but I think between the engine changes that happened this year and the fact that they didn’t go all the way to that low downforce package, we are going to see a pretty racy package that a lot of the drivers have been talking about wanting.”

Q: DO YOU THINK TRYING THESE NEW CHANGES IN THE ALL-STAR RACE AND THE TEST AT MICHIGAN WAS ENOUGH EXAMINATION TO IMPLEMENT THESE CHANGES?

SUHY: “I think the truck arm rule and the fan rule are done for the rest of the season. I don’t really think that needed a lot of testing.  That’s just a matter of trying to get some of the gains that the teams have made in downforce out of the car so they are more like what we had at the beginning of the season.  As far as the new future aero package being tested at Michigan and Kentucky, I do think that is adequate testing.  Actually, that is probably more than adequate based on what we know and how the test went last year on the two packages versus how the racing turned out.  My opinion is you might have been able to do it just based on the tire test at Michigan.”

Q: ARE THERE FURTHER STEPS THAT CAN BE TAKEN TO REDUCE DOWNFORCE?

SUHY: “You get to a point where you can take more downforce off the cars, but there are diminishing returns in terms of the racing quality.  I think there is a sweet spot there.  Along the way you can’t stop working on tires.  Another thing you could to if you really want the cars to be harder to drive, I think, is to put some of the horsepower back in them. There are a lot of things you can do if it’s about making the drivers drive the cars.  I think the teams are working well with NASCAR.  I think the whole competition committee that NASCAR has together is coming to grips with the fact that we, as an industry, have to decide our points of difference.  Where do we want to race each other?  Do we want to race each other with pit guns, or tire fans, or do I want my driver to determine if my car is the fastest?”

A night after wrecking and heavily damaging his car, Kyle Larson came back to win round two of the Cometic Gasket Ohio Sprint Speedweek series Saturday night at Eldora Speedway.

Larson, competing in the first six rounds of the nine-round series with the Cup Series off this weekend, held off former NASCAR driver Dave Blaney late to win the A feature. Blaney fell to third on the last lap. Carson Macedo was second.

Rico Abreu finished 10th. Tony Stewart, who won the B feature, placed 16th. Kasey Kahne was 20th.

The victory is Larson’s first in the Arctic Cat All Star Circuit of Champions at Eldora. It is his seventh victory in the series.

“I made a mistake last night and it cost us a car,” Larson said, according to the Arctic Cat All Star Circuit of Champions report. “This really makes up for that. I’ve now won in every kind of car I have ever raced here at Eldora. That’s pretty cool considering I’ve only raced here like 10 times.”

Ohio Sprint Speedweek continues Sunday at Waynesfield Raceway Park.

Brett Moffitt took the lead at the beginning of the final stage of the M&M’s 200 and held the lead for the final 76 laps to win his second race of the season and the first on his home track of Iowa Speedway.

In the final 10 laps, Noah Gragson and Harrison Burton were able to close the gap as Moffitt lost ground on his older tires. That gave Gragson the opportunity to make a banzai move in turn four. Gragson slapped the wall hard on exit, but retained his second-place position.

Pole winner Burton finished third.

David Gilliland and Johnny Sauter rounded out the top five.

Finishing second, Gragson was able to make up a little ground on points leader Johnny Sauter – cutting the points lead to 71 from 77. Gragson remains second in the standings.

Moffit’s Iowa victory cements his third-place position in the standings.

Stewart Friesen and Grant Enfinger round out the top five.
