Cody Detwiler, known online as WhistlinDiesel, is an American YouTuber and social media personality born on July 18, 1998, in Indiana, USA.
He built a massive following through extreme automotive stunt videos featuring trucks, monster machines, and high-value vehicle destruction. His YouTube channel has surpassed 10.6 million subscribers as of 2026.
Who is Whistlin Diesel?
WhistlinDiesel is the online name of Cody Detwiler, a popular American content creator known for daring and often controversial automotive content.
His videos feature monster trucks, heavy machinery, expensive supercars, and off-road vehicles pushed far beyond their limits.
Many of his uploads involve destroying or heavily modifying high-value vehicles, creating the type of shock-value content that goes viral consistently. He started his YouTube channel on January 7, 2015, posting his first video just days later.
That debut upload was titled “2014 Indiana Bow Season Highlights,” a hunting clip that laid the groundwork for what would become one of the largest automotive channels on the platform. His self-described content philosophy: never upload a boring video.
Cody has built a brand under the WhistlinDiesel name that spans YouTube, Instagram, and Facebook, making him one of the most recognized automotive personalities online.
Early Life of Whistlin Diesel
Cody Detwiler grew up in Indiana, in a family deeply rooted in farming, construction, and the automotive industry.
That hands-on upbringing gave him early exposure to heavy machinery, diesel trucks, and farm equipment, all of which became central to his content.
He was raised as a Jehovah’s Witness. His parents converted to the faith before his birth, meaning Cody grew up under strict religious guidelines that limited social contact and activities outside the group.
Cody later left the religion as a young adult. He has spoken about being shunned by the community as a result, which created strain with family members. He has described his desire to make content as, in part, a way to make up for lost time during those years.
His family operated a construction business, and Cody worked for his father after finishing high school.
That job paid around $1,600 a month. During this same period, still a teenager, he got married — reportedly due to the religious prohibition on dating outside of marriage.
Whistlin Diesel Age
WhistlinDiesel is 27 years old as of 2026, born on July 18, 1998. His zodiac sign is Cancer.
In 2025, he was arrested twice on tax evasion charges in Tennessee, a significant development in his public life heading into his late twenties.
Whistlin Diesel Ethnicity and Nationality
Cody Detwiler holds American nationality and grew up in Indiana, United States. He is of American descent, raised in the rural Midwest in a farming and construction family.
His upbringing in small-town Indiana shaped both his personality and the distinct rural flavor of his content.
Whistlin Diesel Height and Weight
WhistlinDiesel stands at 5 feet 9 inches tall, which equals approximately 1.80 meters. His weight is reported to be around 78 kg (approximately 171 lbs), though this has not been officially confirmed.
He carries a lean, athletic build that suits his active, outdoor-heavy lifestyle on camera.
Whistlin Diesel Career
Early Channel and First Videos
Cody opened his YouTube account on January 7, 2015. His first upload, posted just days later, was a bowhunting highlight reel from a 2014 hunting trip in Indiana.
For several years, the channel remained relatively inactive. His YouTube career picked up serious momentum around 2019, when he began posting more frequently and with higher-production automotive content.
He quickly distinguished his channel from traditional car review formats. Rather than reviewing or test-driving vehicles in the usual sense, Cody modified them in bizarre ways, destroyed them on purpose, or pushed them into extreme situations.
Viral Videos and Monstermax
One of his earliest viral hits was a video showing a four-wheeler fitted with “Reaper wheels” tilling dirt, which accumulated over 14 million views.
The Monstermax became his signature creation. This custom Chevy monster truck, capable of driving through deep water and on extreme off-road terrain, became the centerpiece of a dedicated video series. One Monstermax video of the truck driving in open water alone drew over 26 million views.
He followed that with other high-view videos, including “Hellcat on Horse and Buggy Wheels Goes to Town,” which gathered over 22 million views. His Cybertruck durability test also surpassed 20 million views.
Content Style and Growth
WhistlinDiesel’s approach separates him sharply from standard automotive creators. He buys expensive vehicles, including supercars and heavy machinery, often with the intent of modifying or destroying them on camera.
He purchased a Lamborghini Huracan and an Audi R8, among other high-value vehicles, many of which appear in his content before being damaged or destroyed. In one notable incident, a 2020 Ferrari F8 Tributo caught fire while his team filmed content for his channel.
His channel crossed 10.6 million YouTube subscribers as of 2026. The channel has also accumulated over one billion total views across its video library.
Legal Controversy
In November 2025, authorities arrested Cody at his Tennessee property on two felony counts of tax evasion. The charges centered on the purchase and registration of a 2020 Ferrari F8 Tributo through a Montana LLC to avoid paying Tennessee sales tax.
He was released on a $20,000 bond and arraigned in November 2025. A second arrest followed in January 2026 at a Tennessee airport, with prosecutors adding charges tied to a second vehicle.
Cody denied wrongdoing and described the prosecution as politically motivated. He began selling merchandise featuring his mugshot to raise funds for legal fees.
Whistlin Diesel Girlfriend
WhistlinDiesel was previously married to a woman known publicly as Rae, or Mrs. WhistlinDiesel.
The pair met in high school in Indiana and married in 2016 when both were around 18 years old, reportedly in keeping with the religious community they were part of at the time.
Their honeymoon took place at Glacier National Park in Montana. Rae appeared frequently in Cody’s earlier YouTube content, including a video in which she destroyed one of his trucks.
Rae stopped appearing in his content around 2020 to 2021. Cody publicly confirmed the split in 2022, introducing a new girlfriend named Katie Miller in an Instagram post.
Katie Miller is reportedly a model, photographer, and gamer. She remained relatively private and rarely appeared in Cody’s public content.
Whistlin Diesel Net Worth
WhistlinDiesel’s estimated net worth is $5 million as of 2026. His income comes from multiple revenue streams, including YouTube ad revenue, Instagram monetization, Facebook in-stream ads, brand partnerships, and merchandise sales.
His automotive niche benefits from high CPM rates on YouTube, meaning his content earns above-average advertising revenue per view. He also runs a standalone merchandise business that drives significant direct revenue.
His high-cost content model — buying and destroying expensive vehicles — means production costs are substantial. Yet the resulting viral engagement consistently offsets those costs through advertising income and subscriber growth.
