Michael McDowell, a longtime competitor in the NASCAR Cup Series, has entered the ongoing debate about improving race quality by emphasizing tire modifications over engine power increases. Arguing that suggested horsepower boosts are merely an illusion, McDowell outlined his perspective ahead of the upcoming event at Nashville Superspeedway, making

central to the discussion.
Veteran Driver Rejects Horsepower Solution
Michael McDowell, who made his move from Front Row Motorsports to Spire Motorsports this year, brings considerable experience to the dialogue, having driven in the top NASCAR series since 2008 and piloted various generations of racecars. He is unconvinced that recent proposals to increase horsepower from 670 to 750 will deliver the expected improvement in racing action.
During an interview conducted at Nashville Superspeedway and reported by Dalton Hopkins, McDowell expressed skepticism about the widely discussed power boost:
“I don’t think it will help the product. I think it’s just an illusion that some of the drivers and media are trying to paint.”

Instead, McDowell pointed towards changes that could have a more substantial effect, specifically focusing on tire softness and wear as variables that could create more dynamic races.
“We just need to keep adding softer tires and having more tire wear, and be fine.”

He further emphasized the potential drawbacks of the proposed horsepower increase and maintained an open mindset, stating:
“I think it’s going to be a lot of work for not much of a result on that. We’ll see though, open-minded to it,”
he concluded. —Michael McDowell, Cup Series Driver
Potential Impact of Proposed Changes
While advocates for increased horsepower suggest it could reduce pack racing and reward faster teams, concerns remain that such a shift would mostly benefit well-funded outfits, leaving smaller teams at a disadvantage. The belief is that higher horsepower could lead to more overtaking and stretch out the field, but McDowell views these expectations as untested in practice.
If NASCAR were to prioritize tire development as McDowell advocates, pit stop timing and in-race tire management would become key strategies. Softer tires with quicker degradation could force teams to make tough decisions about when to pit and how aggressively to push, potentially leading to more strategic variety and on-track surprises. According to McDowell, this could create a more unpredictable and exciting racing product for both participants and fans.
Currently, McDowell and other Cup Series competitors are preparing for the Cracker Barrel 400 at Nashville Superspeedway, scheduled for Sunday, June 1, at 7:00 p.m. ET, where this ongoing conversation around race format innovation will remain a focal point.
Challenges at NASCAR’s Mexico City Event
In the same interview, McDowell reflected on his own prior experience at the Autódromo Hermanos Rodríguez, recalling his open-wheel appearance there in 2005 and describing the additional physical demands drivers face at the Mexican venue. He addressed the difficulties presented by the high-altitude environment associated with NASCAR’s first-ever Mexico City race, where recycling thin air may complicate both human and machine performance.
“It’s really tough. I mean it really is. You wouldn’t think it would be, but it is. And just the air, air quality, the height that you’re at, yeah, it’s definitely tough to get acclimated, and it’s a tough weekend. No doubt about it.”

The less dense atmosphere not only affects drivers’ endurance and breathing but also has the potential to strain engines and braking systems through overheating, particularly in a grueling 100-lap contest that will test drivers and equipment around the same circuit used by Formula 1 for the Mexican Grand Prix. The event, branded as the Viva Mexico 250, takes place on June 15 and is the fourth part of Prime Video’s slate of five Cup Series broadcasts for the year.
What Lies Ahead in NASCAR’s Evolution
The question of whether NASCAR should focus on horsepower increases, tire modifications, or both remains open, with Michael McDowell’s advocacy for tire-related strategies gaining attention. As teams and stakeholders debate the best route forward, the outcomes of upcoming races—particularly those impacted by tire decisions—may inform the direction of future rule changes and technological investments in the Cup Series.
