Kyle Larson adapting to IndyCar hybrid challenges at 2025 Indy 500 has become a central storyline as the accomplished driver prepares for another attempt at “The Greatest Spectacle in Racing.” Despite a standout debut last season and high expectations for a smooth follow-up, recent practice sessions at the Indianapolis Motor Speedway have revealed a far tougher path than anticipated, with Friday’s Carb Day practice offering the final opportunity to fine-tune before race day.
Compared to the relative ease of last year’s preparations, this year’s run-up has been marked by two costly crashes—one during April’s open test and another on Fast Friday—and ongoing struggles to perfect the balance of Larson’s Arrow McLaren entry. While these setbacks might suggest a simple lack of fortune, the reality is that the introduction of IndyCar’s hybrid power unit system has fundamentally changed the landscape for every competitor, increasing both the technical complexity and physical challenges facing even experienced racers like Kyle Larson.
After a Promising Debut, New Barriers Emerge
Larson achieved a fifth-place starting spot in his debut, but for this year’s 109th running, he’ll begin in the 19th position—mid-pack, a placement that complicates any hope of an easier run to the podium. Unlike NASCAR, where Larson’s reputation for slicing through traffic is well established, the Indy 500’s level playing field, competitive parity, and the unique track at Indianapolis offer little margin for solo heroics. As Larson noted recently, teamwork becomes indispensable at this level where a single driver cannot simply force their way forward.
“I feel like last year we didn’t really have to mess with a whole lot… I thought the balance was pretty comfortable, but it’s just taken a little bit more time to get to that comfortable spot this year. Happy with where we’re at now.”

This year, fine-tuning the car has required greater effort, and the Arrow McLaren crew has had to adapt alongside Larson to the quirks of the upgraded vehicle. The necessity for team coordination has been emphasized by both his starting position and the unpredictable character of IndyCar’s 2025 machinery. During media availability, Larson underscored these points, referencing his Row 7 start and the resultant hurdles he’ll need to overcome.
“I think for any of us in the field, you have to rely on your team,” said Larson, who during Wednesday’s media availability said his Row 7 starting spot “definitely presents challenges.”

Learning from Past Mistakes and Races
Larson’s rookie campaign was far from mistake-free—after missing second gear during an early-race restart, he fell back to 14th but managed to battle back into contention before a pit road speeding penalty derailed his finish at lap 130. The lesson? Recovery is possible, but only with sharp execution at every key moment. Larson now carries these experiences into his 2025 approach, determined to improve restart consistency while reducing costly errors.
“I had that horrendous restart last year. I think I fell back to close to where I’m starting… We were able to get closer to the front by the three-quarter point of the race. I think if you just (focus on) normal kind of race stuff, execute good restarts and pit stops and things, you can work your way forward without having to work too hard.”

Restart procedures remain a challenge for all drivers, but Larson in particular is focused on smoother execution this year, believing that his previous mishap has actually provided valuable insight into aggressive race maneuvers required from a deeper starting position.
“It was honestly probably good for this year I think to go and have that bad restart, and then you have to get aggressive on some others to learn for this year having to start from, I don’t know, Row 7 or wherever we’re at.”

The Demands of IndyCar’s New Hybrid Powertrain
Perhaps the most consequential change affecting Larson’s preparations has been the addition of IndyCar’s hybrid powerplant. Unlike previous seasons, the new unit incorporates a supercapacitor that allows drivers to strategically boost horsepower—adding nearly 60 extra horses on command—without a cap on total deployment, shifting the tactical paradigm of the race. The system’s added 100 pounds also alters vehicle balance and handling, challenging even the most adept drivers to recalibrate their approach.
While reigning series champion Alex Palou has taken to the hybrid system with apparent ease, other drivers—including Larson—have grappled with its intricacies. Notably, the system’s regeneration button-based controls and changes to weight distribution have been linked to an uptick in practice and qualifying crashes; Larson has been involved in two such incidents during official sessions.
“You see me crash all the time,” Larson said Friday. “I don’t think it usually affects me.”

Hybrid System: Tool or Tactic?
There has been considerable speculation about whether the mastery of the hybrid system offers a game-changing advantage at Indianapolis, but Larson remains skeptical. He regards the additional features less as a dramatic revolution and more as another incremental adjustment—to be managed, not feared.
“The hybrid is, I feel like, hyped up as being this crazy new thing, but it’s really not a big deal either, I don’t think,” Larson said Thursday. “I don’t know what these guys think. But you just pull the paddle and go. When you want more charges, hit a button. It’s not really, like, a big deal.”

Larson indicated on a recent FOX Sports broadcast that, in his experience, the energy bursts from the hybrid are subtle and not as noticeable as the “push-to-pass” function in other series, causing him to focus instead on more tangible aspects of speed management and racecraft throughout the event. Nevertheless, learning the timing and efficacy of these boosts remains on his mind as he looks to maximize both straightaway speed and energy recovery on race day.
Part of the hybrid’s challenge comes from the increased workload inside the cockpit. While other series like Sprint Cars and stock cars rely on a handful of adjustable features, IndyCar demands multitasking on a new level. Fuel mapping, weight jacker, bar adjustments, and now, hybrid management, all require split-second decisions on the fly.
“But then in the IndyCar, you have fuel mappings, weight jackers, bar adjustments, all sorts of other things, too. The hybrid now that you have to keep on top of.”

Adapting to Change On and Off the Track
Kyle Larson’s 2025 “Double” effort—attempting both the Indy 500 and NASCAR’s Coca-Cola 600 on the same day—faces an additional emotional layer this season following the recent loss of his longtime public relations specialist, Jon Edwards. Edwards orchestrated much of Larson’s complex logistics last year, serving not only as a logistical coordinator but also as a steadying influence during intense preparations. His passing in April left a notable void, now filled by Hendrick Motorsports’s Ashly Ennis, who stepped up to ensure a smooth campaign in Indianapolis despite the abrupt transition.
“I think just — had he been here, it would have been more organized weeks ago. But I feel like since he passed, it was kind of like quick decisions on who’s going to be the team around me,” Larson said last week during Indy 500 media availability. “I would say to this point, though, now that we’re here, it’s well-organized, and that’s a lot due to Ashly and everybody at Arrow McLaren, as well. I think everybody with Jon out here worked much harder to make sure it was smooth operating, which it’s been so far.”

Balancing these personal changes has run parallel to Larson’s efforts to internalize the hybrid’s cockpit routines and adjust to the more rigorous IndyCar setup. He acknowledges that while adjusting to stock cars and Sprint Cars has become almost second nature, the technical layers of the IndyCar cockpit—particularly with the hybrid’s arrival—demand more mental bandwidth and a learning curve he continues to climb.
Performance Trends Heading into the Race
Despite the hurdles, Larson’s practice speeds have shown moments of promise, most notably an 11th-fastest lap earlier in the week. However, consistency has been elusive, with other practice positions sliding into the mid-pack—a reality reflected in his qualifying outcome. Each session, from 24th on Tuesday to 33rd on Fast Friday, has offered new data and incremental improvements, but the top end has remained just out of reach compared to the dominant Alex Palou and several series regulars.
Still, Larson sees similarities between IndyCar and NASCAR cars, particularly in the rhythm of tire management and handling characteristics on long runs. These parallels have buoyed his confidence as he integrates lessons from both disciplines, hoping to “enjoy the moment” while maintaining the focus required for strong results at both the Indy 500 and the following Coca-Cola 600.
“It’s definitely the biggest event I’ve ever competed in. It’s everyday is something. It’s really cool. Being a part of it again is really special. Hopefully we can make the (The Double) special and perform well on track, and then do a good job, too, in the NASCAR stuff.”

The Road Ahead: Expectations for Race Day at IMS
With only hours remaining before the green flag drops on the 2025 Indianapolis 500, all eyes are on Kyle Larson’s ability to adapt to IndyCar’s complex new hybrid landscape while overcoming both technical and emotional challenges. Arrow McLaren’s focus on execution, coordination, and steady improvement underpins optimism that lessons from last year and recent testing could coalesce at the perfect moment. Key rivals like Alex Palou, already thriving with the updated technology, provide a benchmark for Larson and his crew as they navigate both the physical and mental rigors of America’s most demanding auto race.
Ultimately, the outcome for Larson at Indianapolis will hinge not only on driving ability but also on his mastery of the hybrid system’s nuances, cohesive teamwork, and resilience amidst both on- and off-track adversity. If his pursuit of “The Double” succeeds under these conditions, it will be a testament to the evolving skill set of one of racing’s most versatile competitors.
