Leigh Diffey became the focus of intense discussion following Harrison Burton’s first Cup Series victory, which he called during a live broadcast that reached millions of viewers. While some fans felt Diffey’s passionate commentary enhanced the historic moment, others reacted negatively, sparking a debate throughout the NASCAR community about his broadcasting style and accent.
Diffey, an Australian play-by-play announcer with a background in Formula 1, IndyCar, and sports car racing, assumed NBC’s lead role for NASCAR commentary in 2023. His enthusiastic delivery has divided viewers—some appreciate the excitement he brings to each lap, while others argue that his style does not fit stock car racing’s tradition.
Key Criticism Ignites Online Backlash
The controversy escalated earlier this month when former NASCAR pit reporter John Kernan publicly expressed his dissatisfaction on social media, directing criticism at Diffey’s commentary during the stage racing segments. Kernan’s post read,
I think I’m done with NASCAR. After further review stage racing SUCKS! And I’m sure Leigh Diffey is a great guy but, if I want to hear that accent, I’ll watch Formula 1. Sorry, guess I’m xenophobic.

This message triggered a heated divide among fans. Some agreed with Kernan’s sentiments, stating they find Diffey’s accent and broadcasting approach distracting or inappropriate for NASCAR coverage. Others defended Diffey, highlighting his enthusiastic presence as key to making significant race moments more memorable and engaging.
When questioned about the backlash, Diffey responded thoughtfully, noting that much of the negativity revolves around his voice, which he cannot change. He said,
Look, the majority of the critics, or the negative Nellies … simply because of the way I speak,
and added,
I can’t choose the way I speak, nor can any of them. We are who we are. We’re all different for a reason. .. You gotta take the positives and plow on.
Corey LaJoie Steps Up to Support Diffey in Public Forum
Corey LaJoie, a NASCAR Cup Series driver, publicly defended Diffey against the wave of criticism. Responding to social media posts about the backlash, LaJoie remarked,
I’m sure the people that say negative rubbish about @leighdiffey are as eloquent as they come…
This statement highlighted LaJoie’s disbelief at the harsh critiques directed toward the announcer.
LaJoie’s endorsement reflects a broader support among some drivers and fans who acknowledge the significance of Diffey’s contributions. Many cite Diffey’s heartfelt calling of Harrison Burton’s Daytona victory as a standout example of his compelling broadcasting, which added emotional depth to memorable NASCAR moments.
The ongoing debate reveals contrasting expectations within NASCAR’s audience. Diffey consistently brings high energy to tracks known for their dramatic racing—Daytona, Talladega, Watkins Glen, and Richmond—yet some viewers feel his Australian accent clashes with the sport’s southern roots. Conversely, others see his international background as a way to elevate the sport’s global appeal.
Future of NASCAR Commentary Amidst Polarizing Views
Despite the divided opinions, Diffey has stated he will not alter his style to appease critics, emphasizing that broadcasting approach ultimately depends on personal taste. While some spectators favor a subdued and traditional broadcast tone, others prefer the vibrant and passionate delivery that Diffey provides.
This debate will likely continue as NASCAR evolves and seeks to maintain a diverse and engaged fanbase. The conversation surrounding Diffey underscores broader questions regarding how NASCAR’s coverage should balance tradition with modernization, potentially shaping future broadcasting decisions.
