Chevrolet has now released its super speedway manufacturer aero kit, after Honda released its on Thursday.
See the full release below.
Chevrolet introduced its speedway aero kit to be used on high-speed ovals in the 2015 Verizon IndyCar Series – including features developed exclusively for running the Indianapolis 500.
The speedway configuration, which was developed in conjunction with the road course configuration, emphasizes the low-drag attributes that enable Chevrolet race cars to achieve speeds of more than 230 mph at the Indianapolis Motor Speedway’s famous 2.5-mile oval.
“With the speedway configuration, the emphasis is on reducing aerodynamic drag, for greater speed, while maintaining sufficient downforce,” said Chris Berube, Chevrolet IndyCar program manager. “Innovative designs were used to develop the right combination of downforce and drag, along with engine performance.”
Highlights of the new design include:
Unique mainplane surface contour serves two purposes, the inboard section directs air to the radiator inlets to enhance engine cooling while the outboard section creates airflow around the front tire to minimize drag.
Engine cover and side pods
The engine cover and side pods are shared with the road course configuration, but are optimized in their speedway configuration by adding close out panels to their trailing edges to reduce drag.
Louvers in the side pods provide cooling benefits and clean airflow to the rear of the car, delivering higher levels of diffuser and rear wing efficiency.
The wheel wedge configuration is fully adjustable, providing various levels of downforce and efficiency to meet changing track conditions.
Rear bumper pods
The rear bumper pods and wheel wedges were designed as an integrated solution to reduce vehicle drag.
A high-efficiency upper rear wing, unique for the Indy 500, features low-mass rear wing pillars and a low-mass rear mainplane.
Chevrolet race teams will compete with the road course aero kit on May 9 for the Angie’s List Grand Prix of Indianapolis, on Indy’s infield road course, before converting their cars to the speedway aero kit for the Indianapolis 500 on May 24.
More than two decades in the making, the pairing of Heather Lyne and Dennis Erb Jr. produced a historical milestone in Dirt Late Model.
Last month, Erb and his long-time crew chief Lyne won their first World of Outlaws Late Model Championship and with this achievement, Lyne became the first female crew chief to win in a national late model series. Their journey together goes back 21 years and tells the story of hard work, persistence and belief in oneself.
“It’s always a challenge when you only have two people, both at the racetrack and at the shop,” Lyne told NBC Sports. “I also work full time, so during the day, Dennis has to do a significant amount of work so that when I get down there I can start working and maintaining. It’s planning ahead. It’s having that system in place and making sure that you’re prepared ahead of time.
“When you have a problem at the track, making sure you have all that stuff ready so it’s a quick change and not a lengthy process to make a repair. We had zero DNFs in the World of Outlaws, we had only one DNF out of 96 races [combined among all series].”
This was not an easy feat. Between a full travel schedule and Lyne’s full-time job as an engineer, time comes at a premium. What they lack in time and resources they made up for in patience and planning.
“We buckled down, and we got all the equipment that we needed back, motors freshened, and things of that nature,” Lyne said about the mid-point of last season. “We were able to keep up with that. We just had a higher focus. I tried to reduce my hours at my day job as much as I possibly could while still maintaining what I need to get done at work. I got rid of a lot of the other distractions and got a more refined system in place at the shop.
“We did certain tasks on certain days so we had time to recover. We were on the road a little bit more, as opposed to coming home to the shop. So we had to be more prepared to stay out on those longer runs. It was just really staying on top of things a little more. It was a heightened sense.”
This was Lyne and Erb’s fourth full season with the Outlaws, but they’ve been on the road together for the last 21 seasons starting in 2001. Their partnership began with Lyne’s bravery. When one door closed, she was quick to open another. In 2001, Lyne’s dad was ready to stop racing. Her mother wanted to regain her weekends, but Lyne knew this was her life path and wasn’t prepared to lose it.
“I’ve always been a tomboy at heart,” Lyne said. “I watched racing with my dad. Growing up he watched NASCAR. In high school, I got tired of playing at the lake house, so I went to the local dirt track and fell in love with it. I just couldn’t get enough. It took a year for me to convince my dad to come to the track with me. He finally did and we sponsored a car that year, the following year he started to race limited cars. He ran hobby stocks and limited late models.”
At some point, Lyne and her father’s level of commitment drifted apart.
“He did it for about five years,” Lyne said. “And then my mom said: ‘I’m done racing. I want my weekends back. It’s just not fun anymore.’ I wasn’t ready to hang up my wenches and Dennis raced out of the same hometown so I, on a dare, went down and introduced myself; told him if you ever need any help, I’ll drill out rivets, I’ll help wash, whatever you need. Twenty-one years later here I am.”
Lyne entered a male-dominated job in a field that is also male-dominated – and where there were few examples of women creating these places for themselves. In this way, Lyne became a blueprint for other women as they strive to find a place for themselves in racing and in STEM (Science, Technology, Engineering and Math) overall. She has her mother to thank for providing a strong role model, her father for sharing her passion, Erb for taking a chance on an unknow entity and most importantly herself.
“I was raised to believe that I can do anything, I want to do, as long as I put my heart and soul into it.” Lyne replied when asked about role models in the sport growing up. “My parents did not raise me to have that limitation. But from a racing role model perspective, I went in there completely green and just introduced myself to Dennis, the fact that he was brave enough to take that risk and bring a girl to the racetrack. Someone he didn’t know at all speaks volumes for him.”
Lyne and Erb have learned how to survive and succeed with each other on the road. They do this by leveraging decades of combined experience and an ability to adapt to the everchanging landscape of dirt late models. Next year the World of Outlaws visits nearly a dozen new tracks and Lyne sees it as an opportunity for continued success.
“I just want to do it again,” Lyne says going into next season, “I’m looking forward to the competition, I always do. I wouldn’t do it if I wasn’t competitively driven.
“There are some new tracks on the schedule that I’m looking forward to trying for the first time that I haven’t been to myself,” Lyne said of the 2023 season, “Dennis seems to do well on those first timers. We won out at Marion center, we finished second at Bloomsburg. We have a good solid notebook of information to tackle them over the last three years with these rocket race cars that we’re running. It’s good to have that information and leverage it to try some new things.”
