What Simon McNamara's return means for General Motors in Supercars
The rebuild of General Motors' Supercars program is due to take a big step this weekend at Symmons Plains.
That may sound like an odd thing to say during the 2025 championship, in which a Chevrolet driver – Will Brown – leads the points, there are five Chevrolet drivers in the all-important top 10, and Triple Eight leads the teams' standings.

All that comes after two seasons of Supercars racing under the Gen 3 regulations, and two drivers' and teams' titles. In two seasons and 52 Supercars races, the wins have been split Chevrolet 38, Ford 14.
The 'rebuild' is about the future, not the present. Next year Triple Eight, the pitlane's alpha team, will race Ford Mustangs. Walkinshaw Andretti United, in past days a consistent winner for Holden, will change brands again, from Ford to Toyota. And the Japanese make is circling for a second team to run its GR Supra Supercars, and rumours persist that Brad Jones Racing remains a candidate for that role.
Enter – or more accurately, welcome back – Simon McNamara. The long-time Holden Motorsport and Sponsorship Manager has returned to the sport, confirming that he has taken on the role of GM Motorsports Supercars Racing Program Manager at General Motors.
Between 2007 and 2017 McNamara was responsible for Holden's Supercars successes. Much of that winning was down to Triple Eight, which raced through the 2009 season without manufacturer branding after being dropped by Ford. Holden and McNamara swooped, the team swapped its Ford Falcons for Holden Commodores, and the rest is history: eight drivers' titles and 10 teams' championships.

But when GM shuttered its Holden brand, McNamara, a 22-year veteran of the company, departed. Triple Eight and fellow Chevrolet team Erebus Motorsport kept the winning streak alive, but there were stirrings at both Ford and Toyota.
Almost exactly three years before McNamara's retur,n Ford recruited Ben Nightingale to its communications team. With a long history in the pitlane, including stints with Supercars itself and DJR Team Penske, it was not long before motorsport in general and Supercars in particular were added to his CV.
Even though his role and McNamara's are not identical, it was on Nightingale's watch that Ford poached Triple Eight away to not only race Mustangs but be its homologation team, a role it has successfully filled for GM.
That move creates the somewhat odd situation whereby, unless something unforeseen happens, the only two Supercars champions racing under the Chevrolet banner in 2026 will be Scott McLaughlin in IndyCar and Shane Van Gisbergen in NASCAR.

If BJR defects to Toyota, it also means that the 14-10 numerical advantage Chevrolet enjoys over Ford will evaporate, with 10 Mustangs, eight Camaros and six Supras on the grid.
From the outside it looks like high on McNamara's to-do list will be to circle the wagons and ensure the remaining Chevrolet teams receive the technical and financial support they require to be competitive. But in light of the incoming changes on the grid for 2026, it could well be a rocky road for Chevrolet fans for at least a couple of seasons.

For the medium to long-term however, the news looks much brighter. The return of the no-nonsense McNamara would not have happened without a clear picture of what GM plans to do in Supercars in the medium to long-term. While Audi's nascent Formula 1 program has seen some of its other racing programs shrink or disappear altogether, GM's Cadillac F1 program does not appear to be a factor in compromising Supercars future – in fact, just the opposite.
Clearly, whether what comes next from GM involves a new model Camaro, Cadillac or something else for what would likely be Supercars' Gen 4, McNamara is sure to play a big role in what that will look like.

Michigan delivers another heartbreaking finish for Carson Hocevar
BROOKLYN, Mich. —While other drivers climbed from their cars after Sunday's 400-mile race at Michigan International Speedway, Carson Hocevar sat in his vehicle on pit road. When he finally emerged from his No. 77 Chevrolet, Hocevar walked around the car and briefly looked off to the distance toward Denny Hamlin's victory celebration. It was another gut punch for the 22-year-old Michigan native. The caution Hocevar needed to stretch fuel to the end of the race never came and a flat tire forced him to pit from the lead 19 laps from the finish. The result was a 29th-place finish that most will forget but not Hocevar. 'It's just like (reliving) the Truck days,' Hocevar said on pit road. 'But you're doing it in front of a big stage. The difference is I felt like I was throwing them away. Now, they're getting taken away … things out of our control.' Nate Ryan, While Hocevar seems poised to score his first Cup career win, heartbreak has hounded him this season. Sunday just added to a growing list. Consider: His engine blew while he ran second in the final stage of last month's Coca-Cola 600 at Charlotte. At Texas last month, he pitted from sixth in the final stage. The caution came two laps later, putting him a lap down and forcing him to take a wave around to get back on the lead lap. If he had pitted a lap later, he likely would have been in a prime spot to win. Instead, he finished 24th. At Bristol in April, he was running third when his team had a 22-second pit stop, ending any chance at victory. Hocevar finished 11th. That doesn't include last week's runner-up finish at Nashville that was clouded by his controversial contact that wrecked Ricky Stenhouse Jr. and led to the drivers and their crew chiefs having conversations during the week. Dustin Long, Sunday's pain was evident in Hocevar's downbeat voice on the radio after the race when he told the team in a soft voice: 'Good job everybody.' Crew chief Luke Lambert quickly added: 'Great work guys. I know that's heartbreaking. Great work. We're putting ourselves in position. We'll keep working. We'll get us there. We'll get us one soon.' Lifting up the team becomes one of Lambert's key roles right now. 'It's hard on all of us,' Lambert said of the recent disappointments. 'We got to just step back a little bit and look at here we are … running constantly in the top three. That in it of itself is an accomplishment. If we keep doing that, our day is coming.' Hamlin agrees. 'You can't run as fast as he's running, being up front as much as he's up front, without eventually winning,' Hamlin said. 'I know that panic sometimes can set in. It's like, 'God, we lost this opportunity.' 'But he's with a team that is on the rise. He is on the rise. It's just a matter of time. None of us would be shocked if it's next week or a month from now or whenever it is. 'I certainly give him his fair share of (grief) on Mondays on my podcast, but that doesn't mean that I don't respect his talent. 'Absolutely just a superstar when it comes to actual raw talent. When he figures out how to harness that, pick and choose the moments where he is aggressive, he's going to put it all together and just be the next whoever. There's five to six elite drivers in this field. He can be one of those five or six very easily when he puts it all together.'

Denny Hamlin wins fuel-mileage battle at Michigan International Speedway
Denny Hamlin took the lead with three laps remaining to win a fuel-mileage battle at Michigan International Speedway. Hamlin moved into first on Lap 197 of 200 past William Byron, who had to pit for fuel in the closing laps and finished 21st. Chris Buesher finished second, followed by Ty Gibbs, Bubba Wallace and Kyle Larson. Ross Chastain, Zane Smith, Kyle Busch, Ryan Preece and Brad Keselowski rounded out the top 10. For the third consecutive race, Carson Hocevar had a good chance to break through for his first Cup Series victory, but the Spire Motorsports driver suffered a cut left-rear tire while leaving with 19 laps remaining. The Portage, Michigan, native was forced to pit under green and fell a lap down in 30th after leading 22 laps. Hocevar tied a career-best finish at Nashville Superspeedway last week and was in contention for the Coca-Cola 600 before an engine failure in his No. 77 Chevrolet. The race was stopped ror more than 11 minutes by a red flag for cleanup of a five-car crash in Turn 2 on Lap 67. Alex Bowman took the worst of it, getting turned into a head-on collision with the outside wall by contact from Cole Custer (who had been hit by Austin Cindric). Bowman walked away from his mangled No. 48 Chevrolet, but his freefall in the points standings continued with his seventh finish of 27th or worse in the past nine races. 'That hurt a lot,' Bowman told Prime pit reporter Kim Coon. 'That was probably top of the board on hits I've taken, and unfortunately I've had a lot of hits. So I hate that for the 48 team. Couldn't really do anything except think about 'Oh (expletive) this is about to hurt really bad.' 'Hate that for our team. It's been a rough two months. I mean, honesty, we were pretty decent (in practice), I was pretty optimistic to start today. We got super loose and just had a long pit stop trying to make an adjustment to make it better. And never really got a chance to race again after that. I'm confident that my guys would have gotten the car better, and we could have gotten back up through there, but unfortunately, when you get in the back like that, (expletive) gets pretty crazy, and stuff like that happens.' WILL BE UPDATED Stage 1 winner: Buescher Stage 2 winner: Byron Next up: Sunday, June 15, 3 p.m. ET at the Autodromo Hermanos Rodriguez road course in Mexico City on Prime.

Alex Bowman hits wall at Michigan as his rough stretch continues in NASCAR Cup Series
BROOKLYN, Mich. (AP) — Alex Bowman hit a wall with the front end of his No. 48 Chevrolet as part of a multi-car crash in the NASCAR Cup Series race at Michigan on Sunday. Bowman got out of the car on his own and walked to an ambulance that transported him to the infield for an evaluation, which he passed. 'That hurt a lot,' he said. 'I've taken a lot of hits.' Austin Cindric's No. 2 Ford made contact with Cole Custer's No. 41 Ford and Daniel Suarez's No. 99 Chevrolet, leading to Bowman colliding with the wall on lap 67 of the 200-lap race. Bowman, who drives for Hendrick Motorsports, came to Michigan 12th in points and will drop in the standings after this latest setback. He has finished 27th or worse in seven of his last nine starts and didn't finish for a third time during the rough stretch. Bowman was in the top 10 in five of the first six races this year, including a runner-up finish at Homestead-Miami in March. He earned his eighth career Cup Series victory last year at Chicago. ___
