Fans of WhistlinDiesel know there’s more to Cody Detwiler than twisted metal and jaw-dropping stunts. His channel has become a haven for viewers who love seeing trucks, tractors, and supercars pushed to extremes. But lately, his personal life—especially his love life—has been just as big a topic as the vehicles he destroys.
In 2025, attention has shifted toward a new figure in Cody’s world: a Russian creator named Daria Grossman. With fan speculation running wild, this guide breaks down what’s actually known about the couple, Cody’s past relationships, and his current net worth.
Who Is WhistlinDiesel Dating in 2025?
As of 2025, Cody Detwiler is believed to be dating Daria Grossman, a content creator originally from Russia. Their relationship became public through social posts where Cody appears alongside her, tagging her directly and referring to her as his girlfriend. These posts offered a casual but clear acknowledgment that they’re together.
This marks a new chapter for Cody following earlier relationships with his ex-wife Rae and later, with Katie Miller. Fans have watched each stage unfold differently, and his relationship with Daria has taken on a more subtle, low-profile tone.
Who Is Daria Grossman?
Daria is a rising digital creator known for dance, artistic expression, and lifestyle content. She posts regularly on social platforms where she showcases a blend of performance, poetry, and personality-driven videos.
Her aesthetic leans bold and expressive, and she has built a growing audience drawn to her creative style. While she’s not as widely known in English-speaking media, she has an active community supporting her online ventures.
What stands out is that Daria is cultivating her own identity. She isn’t framed as “just the girlfriend,” but someone with her own passions and projects. This dynamic has helped her gain attention organically rather than solely through Cody’s spotlight.
How the Relationship Became Public
Cody didn’t make an official announcement. Instead, fans noticed clues through his usual style of posting. He appeared with Daria in photos and reels, and captions hinted at a close relationship. He also released content referring to his “Russian girlfriend,” which paired neatly with her background.
This quiet reveal fits Cody’s pattern. He often shares personal moments without turning them into big headline content. Rather than a formal announcement, the relationship simply became visible through everyday glimpses online.
Fact-Checking Common Rumors
With millions of followers watching their every move, rumors tend to spread faster than Cody can crash a pickup. Several claims circulate online, but not all hold up.
Some fans pointed to someone named “Lujan,” but no credible links tie Cody to anyone by that name. Others misinterpreted the phrase “baby gross,” assuming it referred to a child, though it actually refers to elements of Daria’s online branding. There’s also nothing reliable suggesting any pregnancy or child connected to Cody at this time.
Finally, speculation that he is still with Katie Miller doesn’t align with his recent posts, which show him with Daria instead. The shift in his content points clearly toward a new relationship chapter.
Who Is WhistlinDiesel? A Quick Profile
Cody Detwiler was born on July 18, 1998, in Indiana. His channel exploded by doing what others shy away from—destroying vehicles in elaborate, sometimes absurd experiments. Over the years, he has grown a massive audience that appreciates his straightforward approach and his willingness to go all-in on every idea.
His videos frequently feature trucks outfitted with bizarre modifications, off-road builds pushed past their limits, and expensive vehicles treated with zero hesitation. This unapologetic style has helped him stand out in a crowded creator landscape.
WhistlinDiesel’s Net Worth in 2025
While exact numbers are never publicly confirmed, reasonable estimates place Cody’s 2025 net worth in the multi-million-dollar range, typically calculated around $3–5 million.
His wealth stems from several major streams:
- YouTube ad revenue from millions of monthly views
- Brand collaborations and sponsored segments
- Strong merchandise sales
- Additional income from events or special projects
With over 10 million subscribers and more than a billion total views, the size of his audience supports these figures. His explosive growth over the last few years suggests that his earning potential is still increasing.
A Look Back at Cody’s Marriage to Rae
Before his current relationship, Cody was married to Rae, also known as Mrs. WhistlinDiesel. The two married very young and documented their life together through early videos on his channel. Rae became a familiar presence in those uploads and gained a significant following of her own.
Over time, however, fans noticed that she stopped appearing in Cody’s content. Their separation later became clear as both moved on independently. Rae continues to develop her own platforms, focusing on lifestyle and automotive content.
Neither Cody nor Rae publicly disclosed details about their split, choosing to keep that chapter private.
After Rae: The Katie Miller Chapter
Following his marriage, Cody was believed to be dating Katie Miller for a period. She appeared in some of his posts and was mentioned in entertainment coverage. The relationship seemed less public than his marriage and eventually faded from his content altogether.
By 2024 and into 2025, new posts showing Cody with Daria made it clear that his attention—and his audience’s—had shifted to a new relationship.
How Much Does Cody Share About His Current Relationship?
Compared to earlier stages of his life, Cody now shares less about his relationships. He has shown Daria in posts and acknowledged her, but she rarely appears in his main YouTube content. This suggests he’s intentionally drawing a line between his personal life and his on-camera persona.
Fans still see moments of the relationship, but they’re framed as small windows rather than long storylines. The shift reflects a more balanced approach to sharing while maintaining privacy where it matters.
Why Fans Stay Curious
Part of the ongoing interest stems from Cody’s larger-than-life persona. People often wonder what kind of partner can keep up with someone willing to destroy a luxury car for content. His relationship journey—from a teenage marriage to new partners—adds layers to his public image, making followers even more intrigued.
His selective transparency feeds that curiosity. Viewers get enough to stay connected but not enough to map out every detail, which encourages speculation while respecting boundaries.
Final Thoughts: Cody Detwiler’s Life in 2025
WhistlinDiesel has grown far beyond a typical automotive creator. He’s built a brand that blends authenticity, adrenaline, and an unmistakable disregard for convention. His personal life reflects that same willingness to reinvent himself and move forward on his own terms.
In 2025, he appears to be thriving professionally and personally. His relationship with Daria Grossman marks a new chapter, his net worth continues to climb, and his content remains as unpredictable as ever.
Whether he’s smashing a high-end vehicle or sharing a quiet moment with his girlfriend, Cody continues to do things his way—and fans stay hooked because of it.
