Louisiana Governor Jeff Landry signed House Bill 515 (HB 515) into law, which ensures consumers' choice of vehicle power plants and fuel technologies. This legislation will go into effect on August 1, 2024.
The SEMA-supported law officially prohibits a state agency from restricting the sale or use of motor vehicles based on their energy source. HB 515 passed both chambers of the legislature with overwhelming support. The new law makes Louisiana the latest state to embrace vehicle choice.
"SEMA appreciates Governor Landry and Louisiana's lawmakers for approving HB 515," said Colby Martin, SEMA's director of state government affairs. "As with any automotive advancements, SEMA has continued to support an 'all of the above' approach to vehicle technology policy, advocating for technology-neutral policy that allows the free market to continue to innovate all technology that significantly reduces vehicle emissions."
Several other states have sought similar proposals to promote consumer choice, foster innovation and protect jobs. With this new law, Louisianans, not the government, will continue to decide what vehicles are best for them and their families.

A California bill (SB 301) creating a financial rebate program for converting gas- and diesel-powered vehicles into zero-emissions vehicles (ZEVs) has passed the legislature and now awaits final approval or veto from Governor Gavin Newsom. California has multiple programs to promote the purchase of new ZEVs, but none assist with converting gas-powered vehicles to ZEVs. SB 301 would level the playing field, making it more affordable for Californians to convert their existing vehicles to ZEVs.
The bill is authored by California Senator Anthony Portantino and sponsored by the Specialty Equipment Market Association (SEMA). It would offer Californians up to $4,000 to convert their gas- or diesel-powered vehicle into a ZEV, allowing the Golden State to support small businesses and maintain its rich car culture while assisting consumers who want to convert their vehicles to cleaner motors. Click here to send a letter to Governor Newsom urging him to sign SB 301 into law.
"Governor Newsom has the opportunity to create new jobs and support small businesses by signing SB 301 into law," said Christian Robinson, SEMA's senior director of state government affairs and grassroots. "This bill will also help California reduce emissions and make zero-emissions vehicle conversions more accessible to all residents. SEMA urges the Governor to recognize the tremendous benefits SB 301 brings to the Golden State and sign it into law."
SB 301 has the backing of business and environmental groups. The California Manufacturing and Technology Association (CMTA), the Los Angeles Business Federation (LA BizFed), the California Hispanic Chambers of Commerce, BREATHE California and CALSTART have all endorsed the bill. The California Chamber of Commerce (CalChamber) has also labeled SB 301 a "job creator."

SEMA News sources have revealed the refreshed '25 Ford Expedition's overhauled styling, giving us our best look at this vehicle yet.
Previously, sources revealed the interior, but now we see the refresh includes an entirely new front and rear fascia. New headlights flank a redesigned grille, which sits atop an all-new bumper arrangement. New taillights are completely revealed, but there are some mysteries regarding the rear hatch, which might feature a two-piece design for better loading options, similar to the Range Rover and Lexus LX570.
Also on display are 24-in. wheels, a new addition to the Expedition's options list. Additionally, the refreshed Expedition is expected to offer a range of new tech features and improved interior materials, enhancing both comfort and convenience for drivers and passengers. The updated model aims to maintain its competitive edge in the full-size SUV market with these stylish and functional enhancements.
Inside, the cockpit redesign features a sprawling screen spanning from coast to coast or pillar to pillar, along with an additional screen nestled in the center stack between the HVAC vents, reminiscent of the setup in the '24 Lincoln Nautilus. The revamped Expedition will retain the familiar rotary shift knob, now positioned on a ledge below the center stack screen, accompanied by a volume knob adjacent to it. Completing the ensemble of changes is a redesigned steering wheel, which is yet to be seen.
SEMA and PRI Associate Editor A.J. Hecht attended various racing events in and around Indianapolis throughout the month in the lead-up to the 108th Indianapolis 500. Read some of his thoughts and observations below:
There is really nothing like May in Indianapolis. The race breathes life into the entire city. The trees bloom, the sun shines, the city bustles and thousands of people descend on the Crossroads of America to witness the largest single-day sporting event in the world.
Naptown? Not in this month.
Everywhere you look, there's a checkered flag. Dangling from balconies, mounted on flag poles, stuck in carefully maintained flowerbeds dotting the Circle City.
And it's not just about what's going on at the Brickyard.
In Anderson, the sprint car world gathered for the Little 500. In Winchester, the USAC Silver Crown circus competed for the Rich Vogler Classic, then moved on to Brownsburg for the modern-day Hoosier Hundred. Up in Kokomo, the High Limit Series made its first-ever visit. Meanwhile, late models and wingless sprints lit it up in Bloomington.
It's a magical month if you're a Hoosier. It's heaven if you love racing.
Friday, May 10 -- Sonsio Grand Prix Practice and Qualifying
I was fortunate enough to attend a testing day in April ahead of the Sonsio Grand Prix, the NTT INDYCAR SERIES event that serves as the opening for the "Month of May" at Indianapolis Motor Speedway. That day, the speedway was relatively empty. That was not the case on Friday.
Pit lane, of course, was bustling, filled to the brim with tires, spare wings, coolers, crew members and scores of onlookers, snapping photos of their favorite drivers. The Pagoda Plaza, a prime gathering spot for fans wandering the gigantic facility, was humming with activity, smelling like fried food and gasoline. The biggest difference, however, was the presence of the famed "Yellow Shirts," the intrepid crew of security, crowd control and do-it-all-ers for IMS. Their whistles are ubiquitous here, especially as you approach Gasoline Alley, halting fans and allowing, cars, crew, and tuggers and dollies stacked with Firestones to and from pit lane.
The action wasn't confined to pit lane. Behind the suites, the INDY NXT squads geared up for a practice session of their own, firing up engines, pulling their spec IL-15 Dallaras out of the garage before heading out on track.
The media center, too, was filled with life. Writers and photographers, radio and television personnel, PR and marketing staff, all plugging away on their computers to meet deadlines, update their Twitter followers or fire off emails.
A steady stream of on-track action meant a continuous hum of background noise, with USF Pro 2000 and USF 2000 supplementing the soundtrack for the opening weekend of May. Music to my ears.
Saturday, May 11 -- Sonsio Grand Prix
For many, the Month of May is about traditions, of which there are many. There are the traditions of the race: 11 rows of three, a cold glass of milk, "Back Home Again in Indiana," etc. You likely know most of them. Fans also have traditions of their own: a morning tailgate, drawing names for the family pool, snagging souvenirs, whatever it is that makes the day special. Some have been going on for years, decades even. Others are new. After all, traditions have to start somewhere.
The Sonsio Grand Prix is a new tradition for my family. We attended our first "Grand Prix" last year. With one under our belt, we knew what to expect and claimed a spot on a viewing mound at the end of the backstretch. In the middle of the quick left-right-left that is Turns Seven, Eight and Nine, we saw plenty of action, including a staggering number of passes for position and frequent four-wheel slides from cars running on the absolute limit.
Seeing an Indy car driven at that speed and intensity gives you an appreciation for not only the performance but the durability of the car and its parts. As they approach the hard left at Turn Seven, the engine is at full song. In a matter of moments, the driver slams on the brakes, now glowing red, and clicks down through the gears, then throws the car into the corner, tires screaming and spinning as they jump back on the throttle. Imagine the heat generated, the stress on the tires, the shifting weight load on every corner of the car, pushing the suspension, the gearbox, the brakes, the engine, to the knife's edge. These cars are modern marvels.
The Indianapolis Motor Speedway was built in 1909 as a place to test the early automobile. It's sometimes easy to forget that a modern-day Indy car is the result of that 115 years of history, but to this very day, the Speedway is living up to that original mission as the motorsports industry pushes the boundaries of what's possible.
Tuesday, May 14 -- Opening Day of Indianapolis 500 Practice
No "Month of May" is complete without a washout, although the day wasn't completely lost. Drivers, including NASCAR star Kyle Larson, were able to get some limited track time, but green-flag conditions lasted just 23 minutes. That was enough track time, however, for Scott Dixon to lay down a blistering lap of 229.107 mph, and Marco Andretti to dust off the cobwebs with a lap above 228 mph.
Wednesday, May 15 -- Indianapolis 500 Practice
Wednesday didn't look too much different from Tuesday, but there was some on-track activity in the morning. Unfortunately, there were no Indy cars, just jet dryers, street sweepers and a fleet of Silverados, racking up laps in a futile attempt to dry the soaked pavement. It's a familiar sight for any veteran INDYCAR fan.
Luckily, the sun came out, the track dried up and we got to see some cars on track in the afternoon. With the green flag flying at 3 p.m., it was a mad dash to make up for lost time. Within the first hour, 33 of the 34 entries had completed at least one lap, and Scott McLaughlin picked up right where his countryman left off on Tuesday with a lap just north of 229 mph, the fastest of the day.
Meanwhile, the rest of the speedway came to life. Fans packed the sections of open grandstand and dotted the viewing mounds in the infield. After almost two days of rain, it was nice to see some of the fervor and energy that we've all come to expect from IMS.
Thursday, May 16 -- Indianapolis 500 Practice

A clear forecast meant lots of action as teams made up for lost time, not only from the previous two rain-soaked days but also a lost day during the April open test. Colton Herta threw down the gauntlet early with a blistering 224-mph lap without a tow, the speed chart to keep an eye on for a preview of likely pole favorites.
The flag stand, which sits directly above the Yard of Bricks, was missing its usual occupant for the start of practice, as Aaron Likens, the chief starter for the series, celebrated the release of his new book, Playing in Traffic. Likens, who was diagnosed on the Autism spectrum in 2003, has carved out a spot for himself in the paddock and describes what it took to get there.
Starting out flagging club races in St. Louis, Likens worked his way up through the ranks and credits his passion for racing as the driving force behind his career in motorsports.
It's something he picked up on after watching Mario Andretti flag a quarter-midget race in Phoenix earlier in his career, he said. Andretti, who was the honorary starter for the event, wanted to stick around the flagstand for the rest of the race.
"You're not going to say no to Mario," Likens said.
Throughout the heat, Andretti was totally invested in the race, Likens told me, pointing out comers and goers, critiquing lines, and calling out passes before they happened.
"You can be passionate about something, but to have it in your soul to where you live and breathe it, people pick up on that."
Now an integral part of the series, Likens says it's a dream come true to be able to flag the Indianapolis 500.
"I came here as a spectator 20-plus times and to now be on the other side of the fence, to be a part of it," he said, "I probably didn't do it justice in the book just what that feels like."
On track, the day took an unfortunate turn for two drivers: Linus Lundqvist, the Swedish Chip Ganassi Racing driver attempting to make his first 500, and Marcus Ericsson, the 2022 winner and last year's runner-up. Both put their Honda-powered Dallaras in the wall, with Lundqvist tagging the Turn Two SAFER Barrier and Ericsson absorbing several hard hits against the Turn Four retaining and inside walls before bouncing off the pit wall attenuator.
Any wreck during Indianapolis 500 practice is a major setback, no matter what team takes the brunt of the impact. Chassis are regularly written off due to hard hits at the Speedway, and a car that has spent months in the shop in preparation for the "Greatest Spectacle in Racing," can be lost in an instant.
After Ericsson's incident, the recovery team brought the heavily damaged car back to the Andretti Global garage for assessment. By the end of the day, the 28 team was preparing the backup car.
Friday, May 17 – Indianapolis 500 Practice – Fast Friday
Pulling into the parking lot felt a little bit different on Friday morning. As I mentioned before, the speedway has a very different feel when people start to fill the grandstands, even more so on Fast Friday, when INDYCAR turns up the turbo boost and the speeds flirt with the low 240s at the end of the straightaways. Thanks to some offseason weight reduction, some were positing that the long-standing track record, set by Arie Luyendyk in 1996, could be in jeopardy. That speculation added to the already infectious buzz of the speedway after emerging from several days of stifling rain.
Unfortunately, the day was marred by a crash from rookie Nolan Siegel, who lost it in Turn Two and ended up on his lid. He was okay, but the car was not.
The rest of the day was incident-free, with teams gauging their true speed and pole potential on four-lap "qualy sims," making repeated trips from pit lane to Gasoline Alley and back, looking for tenths, hundredths of a mile per hour, whatever they could find.
Back in the garages, teams stripped down their cars to the bare bones, cooling engines and tweaking setups, while Firestone, INDYCAR's exclusive tire provider, continued its herculean effort to supply the 34 entries with fresh rubber.
On Friday, I had the pleasure of speaking with Cara Krstolic, executive director of race tire engineering and production for Firestone, and Mark Williamson, the service crew manager, who is tasked with leading the team—18 techs strong—as they mount and balance tires for each team.
Thanks to the expanded grid and extensive track time available to the entry list, Firestone goes through 5,000 tires during the "Month of May," almost five times the number of slicks used over the course of a typical INDYCAR race weekend.
It was an enlightening conversation, and Pat Caporali, the PR rep for Firestone, pointed out a small piece of information that is representative of the level of detail surrounding the entire operation. If you have a sharp eye, you'll notice that some of the Firehawks are marked with red Firestone "F" badges. Others have a white badge. The difference? Red is for right-side tires. White is for left-side tires.
I wrote up a more extensive account of our conversation, so if you'd like to hear about the operation in a little more detail, check that out here.
Saturday, May 18 – Indianapolis 500 Qualifying – Day 1
If you've spent any time in the paddock or followed INDYCAR for a while, you know that the four laps it takes to qualify for the Indianapolis 500 are among the most stressful, on-edge laps a driver will ever run. Just ask Rinus Veekay.
Only 23, the young Dutchman has already competed in four 500s and never started worse than fourth. But on Saturday, during the fourth run of the day, Veekay's car snapped loose on the exit of Turn Three and ended up on the hook of a Stepp's Race Recovery tow truck.
Back in the garage, Ed Carpenter Racing feverishly pieced the car back together, and, before long, got him back on track to secure his place in the show.
Although it didn't quite reach his usual front-row potential, the 2021 GMR Grand Prix winner put it into the field, 29th on the scoring pylon. But, as it turns out, that wasn't the end of the ECR driver's day.
Any reasonable person would advise against pulling your car out of the Indianapolis 500, even if it means starting a few rows further up, but that doesn't mean it doesn't happen. On Saturday, Veekay and his team made the call to withdraw their time and jump the lengthy line of cars waiting for one more shot at a four-lap run, a call that ultimately paid off.
With just minutes left on the clock, Veekay took to the track with a roar of approval from fans, and drove his way into the Fast 12, the group with the privilege of coming back on Sunday for a shot at the Pole.
"The crew got the car back together in under three hours, which is incredible to start with. Then to get a banker run in, get the car cooled down, go back out again at the end and do that. I never lost hope, but I never expected us to do that," he said. "It's such a great story, such a great job by the guys. I think they are the real winners here today."
Even before Veekay's "Hail Mary" run, the tension was palpable, especially in the pits. I've been going to Indy 500 Time Trials since I was barely able to walk, but this was the first time I've watched from anywhere other than the grandstands.
Seeing the teams up close, watching their drivers out on track, you can feel their nerves. As Takuma Sato took the checkered flag on his second run of the day, a crew member stood at the Yard of Bricks, cheering the two-time 500 champ down the frontstretch and into the Fast 12. The enthusiasm--or for those who didn't qualify, the dejection--goes to show how this race is about more than the driver.
Teams and crews spend months preparing for the "Greatest Spectacle in Racing," even though a spot isn't guaranteed. They give everything--blood, sweat, and, surely, tears--waiting for May to come back around, for another crack at racing immortality, even though their face won't end up on the BorgWarner Trophy. But the joy, pain and excitement aren't possible without the crews, their investment of time and energy, and are just as much a part of a winning effort as anyone else.
Sunday, May 19 – Indianapolis 500 Qualifying – Day 2
Like I have many times before, I watched Pole Day from Stand E with my family. With the Pole on the line, as well as the last three spots on the "500" grid, the day was primed to be full of drama. It lived up to the expectations.
Graham Rahal, trying to make the field after being bumped in 2023, once again found himself in the Last Chance Qualifying group, fighting for one of three vacant spots on the 11th and final row alongside 2022-winner Marcus Ericsson; Katherine Legge, attempting to make her fourth 500; and Siegel, an 18-year-old rookie.
As a fan, I can't recommend attending Pole Day enough. The access is incredible and the action is always compelling. While race day is great and an experience unlike any other, days like Pole Day also create life-long fans. One of my earliest memories of the speedway is sitting in the first turn, watching Greg Ray, Scott Sharp, and Billy Boat out on track, then walking by Gasoline Alley to see the cars getting pushed back to the garage. There's usually some time to kill and opportunities to walk around and absorb the grandeur of the speedway and the event.
One thing the Indianapolis 500 does particularly well, in my opinion, is providing ample opportunity for people to get to the track, whether you're a diehard who doesn't miss a session or a parent looking for a weekend activity for your kids. Half the battle is getting people in the door, and a low barrier of entry goes a long way.
Our entire afternoon at the speedway, we were surrounded by families. Some young, some old, but I can almost guarantee that when Alan Bestwick announced Scott McLaughlin's first lap of 234.5 mph on his eventual Pole run, many new fans were born. There are few moments in sports that equal the shock of a fast lap at the Indianapolis Motor Speedway. The speed flashes on the screen, the public address announcer's booming voice echoes through the grandstands, drowned out by cheers, and the anticipation builds as the driver pushes the limit for three more laps.
It's a fun, entertaining and simple day that is easy to follow along with for any new fan, thanks to the relatively simple task at hand: who can go faster?
But the highs must come with the lows.
Siegel, after being forced to a backup chassis, was never able to find the speed to secure a spot in the race, despite pulling with a fraction of a second of Rahal, the 33rd and final qualifier.
In a last-ditch effort to make the show, the 18-year-old left it all on the track, losing control of his Dale Coyne Racing Dallara in Turn One of his second lap. Once again, his day ended at the Infield Care Center, unhurt, aside from the pain of missing out on one of the biggest races in the world.
However, he did take some solace in the fact that he--and the team--did everything they could to make the field.
"We took a swing at it to try and find half of a mile per hour," he said. "I was going to go home because I went flat and did everything I could do. I wasn't going to go home because I lifted."
Stay tuned for "Behind-the-Scenes: May in Indianapolis -- Part 2" which will include dispatches from motorsports events beyond the Brickyard, including USAC dirt and pavement action, memorabilia shows, a race shop grand opening, and more.
Laying Down Rubber: Supplying Tires for the Indy 500
Months of preparation, an expanded team and a focus on the details help Firestone, INDYCAR's exclusive tire supplier, succeed on the biggest stage of the year.
By SEMA News Editors
It doesn't need to be said that the Indianapolis 500 is the biggest race of the year for the NTT INDYCAR SERIES. It's the biggest field. The biggest crowd. The biggest purse. The biggest stage.
And with the most on-track time of any race, it means a little more of everything. More fuel, more engines, more manpower, and more tires. A lot more tires.
In a typical INDYCAR weekend, the field of 27 full-time cars uses somewhere between 1,100 to 1,200 Firestone Firehawks across multiple practice sessions, qualifying, and the race. But the Indianapolis 500 is not a typical INDYCAR weekend.
For the four days leading up to qualifying, the track is open for practice for six or more hours, totaling in more than 30 hours of available track time. And that doesn't include the two full days of qualifying over the weekend.
With all the extra running and the expanded grid, the 33-plus entries will use more than 5,000 tires--yes, 5,000--over the course of the month.
To accommodate the extended practice time, larger car count, and increased workload, the tire manufacturer adds four to five members to its usual 14-person service team, according to Mark Williamson, service crew manager. Throughout the day, Williamson and his staff tend to the needs of the paddock, dismounting used tires (dropped off throughout the day by teams), mounting new slicks on each team's rims, and finishing the process by balancing each tire.
Each step in the process only takes one minute per tire. "Not exactly your local shop," Williamson said.
In addition to preparing each tire, several members of the service crew are also tasked with roaming pit lane while the track is hot, measuring tire temperatures and air pressures from used tires once they come off the car.
Despite the constant and heavy workload, each tire is meticulously tracked, marked with a serial number and barcode, and followed through each step in its life cycle, from manufacture to post-race analysis.
The week begins in anger even before the drop of the green flag on the first practice session, with work ramping up as teams arrive at the track in the days before the opening session. But preparation for the race starts months, even years in advance.
"We're learning right now for next year," Cara Krstolic, executive director of race tire engineering and production for Firestone. "We have an engineering team and at least one chemist at every point to understand what's going on with the tires, working with the drivers on feedback, with the race teams on what they want out of the tire and what they need out of the tire."
In fact, Krstolic and the Firestone engineering team began developing a new tire to better account for INDYCAR's incoming hybrid power unit in October 2022. Originally intended to be in use for the full 2024 season, the hybrid is now slated to debut at the Honda Indy 200 at Mid-Ohio Sports Car Course later this summer. Firestone still had to be ready.
"We started a year and a half beforehand to make sure we had the appropriate tire for whatever the race throws at us," Krstolic said, "whether it's a hybrid, whether it's not a hybrid."
In addition to large, wholesale changes mandated by the sanctioning body, the series' official tire supplier must also be ready for innovations coming directly from the race shops.
"The cars are constantly changing, even if there are zero changes to the cars itself," Krstolic said. "Engineers are finding out new ways to run their cars faster, and that adds new stress to the tires, or adds different conditions than the tires were initially designed for. We're continually learning and that drives our process."
That process includes extensive design reviews and consulting feedback from teams, including year-end debriefs with the full Firestone engineering team. In total, a design review cycle takes about a year, Krstolic said, but the changes always keep coming.
"There's no end of the design or beginning of the design," she said. "We learn as we go."
Changes to the cars and new approaches from the teams are compounded by the unique surfaces of each track. A detailed analysis of the pavement--whether it's a pristine oval like Indianapolis or the winding, weathered streets of Toronto--informs the design process. The engineering team completes a friction analysis and a laser analysis at each circuit to determine the level of grip provided by the pavement, as well as an understanding of how the tire will behave, especially as cars are getting up to speed.
And Indianapolis Motor Speedway, Krstolic said, possesses a very specific challenge.
"What makes Indianapolis unique, other than the amazing history we have here, is the very long straights followed by sharp turns. A lot of people call it an oval. It's really a rounded rectangle," she said. "That provides unique challenges because you have a long time that the tire will cool off, then you enter a turn. Mario Andretti says it's like, 'driving 60 mph down a country road and then turning into your driveway.'
"In some ways, it almost acts like a road course because you don't have a long-duration turn, so it's a very unique race track," she added. "We love coming here, we love designing tires for it. It's always a great engineering challenge and it's a great way to showcase our product."

One of these four will be crowned the overall BOTB champion during this year's SEMA Show, November 5-8, Las Vegas. Industry experts serve as judges and review all qualifying applications, including vehicle descriptions and photos, before walking the SEMA Show floor to review builds in person and select the Top 10 finalists in each category. The finalists are then narrowed down to the Top 3 in each category, and these 12 finalists become the judges and select the winner of each category and the overall champion.
"Battle of the Builders has opened the door for builders on an international level, providing a world stage for their custom cars and trucks," said Cam Miller, Hot Rod & Hot Rod Truck judge and former Battle of the Builders Overall Champion. "The uniqueness of the builds and how builders use the industry's finest parts is always one of the most exciting parts of the contest."
A special element of SEMA Battle of the Builders is the Young Guns category, which is open to builders who are 29 years and younger at the time of the SEMA Show. As part of SEMA's initiative to support the next generation of builders, Young Guns entries can compete in one or more virtual Golden Ticket competitions for the chance to win a prize package that includes transportation of the vehicle to the SEMA Show along with travel and hotel accommodations.
"Battle of the Builders has helped launch the careers of dozens of builders by bringing both established and up-and-coming modifiers to the forefront of the global automotive stage," said de Vera. "The vehicles that are entered into the competition are truly iconic builds that take the world of customization to new levels."
