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?”

Mechanical issue drops Martin Truex Jr. to final transfer spot entering Kansas

Leave a comment

TALLADEGA, Ala. — Martin Truex Jr. knows Sunday’s race at Talladega Superspeedway could have been worse because of a mechanical issue that made his car “evil to drive.”

The result is that Truex, one of the members of the Big 3 that has dominated the series this season, holds the final transfer spot entering next weekend’s cutoff race at Kansas Speedway.

With an issue in the rear gear, Truex said he fought the car most of the race.

“Couldn’t even go straight,” he said after finishing 23rd. “There was no chance of me getting up there and racing as much as I wanted to.

“I rode around all day broke, hanging on, miserable. I couldn’t even race, my car was so screwed up. It felt like the rear end housing was falling out of it.”

The struggles had him in a spot late in the race where he would have been outside the cutoff spot heading to Kansas.

Truex’s fortune changed when some playoff drivers, including Brad Keselowski, had to pit for fuel in overtime and gave up several spots.

Instead of being outside the cutoff,  Truex enters Kansas in the final transfer spot and has an 18-point lead on Keselowski and a 22-point lead on Ryan Blaney.

Truex won at Kansas last fall and finished second there in May.

“I think that’s a good place for us even if we had to win,” Truex said. “I am not saying we’re going to go there and win. But anytime we can go to any of those tracks, I feel like we have a shot. It’s racing. A lot can happen as we saw today. We’ll give it everything we got and bring a great car to Kansas. We’ll try to get the checkered flag.”

What drivers said after the Cup race at Talladega

1 Comment

Aric Almirola — Winner: “I felt like I kept giving it away and I was so disappointed for all these guys behind me because they’re awesome. They’re the best. I’m with the best team in the garage and I felt like I kept letting them down not winning a race. Today, the Good Lord was shining on us and we went to Victory Lane. We did it, finally.”

Clint Bowyer — Finished 2nd: “Man, that was about as easy of a Talladega race as I have ever experienced. What a day to be in a Ford! Every time I looked in my mirror it was a wave of blue ovals. What a day for SHR, too. That was all about cooperation. There’s no way you could overstate how good our cars were today. We finished second in both stages and the race, so that’s a pretty good day for us. We’ll go to Kansas and get a good run and make sure we are in the Round of 8 after next weekend.” 

Ricky Stenhouse Jr. — Finished 3rd: “We definitely had to fight hard today. We weren’t near as good as we normally are at the speedways, so that was a real bummer, but we fought hard and made a lot of adjustments to try and make our car faster. It seemed to work a little bit there and obviously fell on the lucky side of having to pit and having enough fuel, so everything worked out good for us today to get that good finish and back-to-back top 10s is a start.”

Denny Hamlin — Finished 4th: “I thought we were the next best in line today. The Ford cars seemed to have a little more speed than us. We stayed disciplined and in line there. We chose the right line when the lines came. Got a great top-five finish today. We were almost the best in class there.”

Joey Logano — Finished 5th: “Those Stewart-Haas cars drove great and they were really, really fast. They showed it in qualifying and they were so committed to each other and they did a great job. They probably would have finished 1-2-3-4 if they didn’t run out of gas, so they were definitely quick. We had a pretty good Shell/Pennzoil Ford, not the winning car, but definitely a top-five car, the best of the rest you could call it. We scored some stage points and then a solid top five, so I’m proud of that. I don’t know where that puts us in points, but I think it puts us in a decent spot to where we can go to Kansas and race hard, so not that we didn’t race hard today, but it was just gonna take a lot to beat the teamwork and the cars that they had today.”

AJ Allmendinger — Finished 6th: “I thought prior to the final restart I got myself in a good position on the outside there. It just seemed like every time the line went to move somebody made a move and it checked the lineup. I was just getting pinned out there. I thought my car handled good compared to the guys I was around. I thought that was our strength. And then the No. 88 (Alex Bowman) got turned, I saw him get turned and figured at some point he was going to come snapping back up the race track and I was like to say that was skill missing that, but it was pretty much luck that he didn’t hit me. The final restart was just trying to pick a lane. A couple of guys ran out of fuel coming to the green, so we got to move up a couple of rows and then it was just trying to pick the right lane coming to the checkered. For once we didn’t wreck at Talladega, so that is a good day.” 

Kyle Larson — Finished 11th: “We just had a terrible race car and were really slow all weekend. We were able to salvage a decent finish, but the Fords are so fast here and can rack up a lot of stage points. Even when they have a bad day, they still gain points on us. It is what it is. We’ll just go to Kansas and try and win.”

Kurt Busch — Finished 14th: There was two missed calls by NASCAR at the end. Why did we have an extra yellow flag lap is beyond me. The track was ready to go. And at the end. Once we crossed the white flag, if there’s a wreck and an ambulance needs to be dispatched. I’ve been on the other side of that where I was racing coming back to win the race and they said ‘Well, we had to dispatch an ambulance.’ There was two cars dead in the water.”

Ty Dillon — Finished 15th: “This was a solid day for our GEICO Camaro ZL1 team. We didn’t make any mistakes on track. My spotter did a great job and kept me clean all day. Talladega has always been a strong track for me because I’m comfortable with this style of racing. This was the kind of day our team needed after a couple of tough weeks. We ran up front, earned a bonus point at the end of Stage 1 and showed once again that Germain Racing builds fast superspeedway cars. I wish we could’ve gotten a top 10, but those are the brakes sometimes at these tracks with how quickly drafts change and cars move around. I’m proud of my team’s effort today, and I’m looking forward to Kansas next weekend.”

Austin Dillon — Finished 15th: “To he honest, I was worried at the start of the race because the American Ethanol Camaro ZL1 was not handling very well. My crew chief, Justin Alexander, and the team worked hard to fine-tune our Chevy throughout the race and we were able to earn some Stage points at the end of Stage 2. We opted to hang back in Stage 3 in anticipation of ‘The Big One.’ We knew that if we could avoid that, we would have a solid shot at the end. It didn’t work out quite the way we hoped with a relatively calm race and not enough laps to get to the front at the end. You win some, you lose some.”

William Byron — Finished 20th: “It was good. I thought my goal was really to survive. We were fortunate to lead some laps when we got the track position, which was good. Just couldn’t get enough guys to work with me. Hopefully, next year will be different with the rookie stripes off, it should make a difference, but other than that I thought our day was good. Got the car better handling-wise, handling was pretty important and then from there we just were kind of trying to fight for track position. I was able to bring it home, which was good.”

Martin Truex Jr. — Finished 23rd: “It didn’t really matter what we did to the car. It didn’t go away. We tried a lot of stuff. It was tough to drive. It couldn’t even go straight. I could run hard for two or three laps. As soon as the tires got some air pressure, I was just hanging on. The longer the runs were, the worse it got. There was no chance of me just getting up there and racing. I wanted to. Luckily, we were able to get some tires there in the end. I could go for about three laps. I felt good going to the green-white checkered. They wrecked in front of us and we barely made it through. As soon as we got through there, I was able to salvage something.”

Ryan Newman — Finished 25th: “Before the final stage, we did a fuel-only pit stop to give us options later in the race. We were in lucky dog position for the final 20 laps and eventually caught a break to put us on the lead lap with two laps remaining. However, in overtime I was caught in a wreck and the car was heavily damaged. I know we were better than where we finished, P25. Sometimes the dominoes just don’t fall your way. We’ll be ready for Kansas next week and hopefully string together some solid runs to close out the year.”

Kyle Busch — Finished 26th: “We tried everything today and struggled to get up front.”

Brad Keselowski — Finished 27th: “We ran out of gas from what I could tell, so we’ll go through and look at it and see.” 

Kevin Harvick — Finished 28th: “I’m just really proud of everybody at Stewart-Haas Racing. Mine sputtered there on the fuel pressure and it dropped down in the red and they did the right thing of coming in and pitting and not taking a chance. You just need to put yourself in a position to where you’re good for next week and just glad that one of our cars won and happy for Aric.”

Chase Elliott — Finished 31st: “Yeah, I mean it is what it is. We were far enough back in the pack where if it does happen you are probably going to be in it. Yeah, it happens.”

Late fuel stop adds to ‘frustrating three weeks’ for Brad Keselowski’s team

TALLADEGA, Ala. — All that positive momentum Brad Keselowski’s team had entering the playoffs is long gone after another frustrating finish that has his title hopes in jeopardy.

Keselowski pitted for fuel in overtime and finished 27th Sunday at Talladega Superspeedway. He is 18 points out of the final transfer spot entering next weekend’s race at Kansas Speedway.

“Ever since Richmond, we haven’t done much, made bad decisions and we didn’t have speed this weekend, and last weekend was bad,” crew chief Paul Wolfe told NBC Sports. “We wrecked two cars at the Roval. It’s been a frustrating three weeks and now we’re sitting I don’t know how many points out … We’ll go to Kansas and do what we try to do every week and that’s win and see what happens.”

It’s a marked change for the team, which won the Southern 500 and at Indianapolis to end the regular season and won the playoff opener at Las Vegas.

At Richmond, Keselowski finished ninth, hindered by a slow pit stop in the first half of the race. At the Charlotte Roval, he was fastest in practice but crashed in the final session and had to go to a backup. He crashed while leading late in the race and placed 31st. Last week at Dover, Keselowski finished 14th after he was hit by Aric Almirola in the final laps and his car was damaged.

“We made a bad call not to pit last week there at the end and then we got run over,” Wolfe said. “So that’s not good.”

Sunday, Keselowski had a loose wheel that forced him to stop under green and fall a lap down. He recovered to lead 21 laps but Stewart-Haas Racing’s cars were clearly better.

Why?

Sounds like they’ve got some really good engineering,” Keselowski said.

The team made some changes this weekend to the car but couldn’t counter the Stewart-Haas Racing cars.

“We went for handling today, thought that’s what we needed and I don’t know, I didn’t really see it pay off for us,” Wolfe said. “There were cars out there driving a lot worse than we were but we weren’t able to capitalize on it. Disappointed in that.”

Keselowski was running ninth when the race went to overtime and then pitted for fuel while most of the field stayed out.

“We just got a little bit of air in there and I think he panicked and came to pit road and likely should have just rolled on and we would have probably run out down the back (straightaway) or something but had enough speed to carry it around and maybe finish a few spots higher,” Wolfe told NBC Sports.

“When you get down to the end like that and you got a lap-and-a-half of fuel, we’re talking about half a gallon of fuel, you’ve got to be really aggressive keeping that pick up full and sometimes you‘ll get a little sputter there and got to let it recover and go on. It’s just been a frustrating three weeks.”

Aric Almirola passed a fuel-starved Kurt Busch in Turn 4 on the final lap of  the 1000Bulbs.com 500 at Talladega Superspeedway to win his first race of the season and advance to the third round of the playoffs.

Teammate Clint Bowyer followed him across the line.

Ricky Stenhouse Jr., Denny Hamlin and Joey Logano rounded out the top five.

Stewart-Haas Racing started first through fourth and ran that way for most of the race. With less than 10 laps remaining, they separated from the field – building an advantage of more than 20-car-lengths with five to go.

That advantage was erased with three laps remaining when Alex Bowman spun and brought out the caution.

Kurt Busch fell to 14th on the final lap. Teammate Kevin Harvick pitted as the field was about to take the green flag. He finished 28th.
