Cody Detwiler, better known online as WhistlinDiesel, had wanted an Ineos Grenadier for two to three years before actually buying one. He said as much on camera, insisting the plan was to buy a bright red Grenadier and simply keep it nice. It took about twelve minutes on video to prove that plan was never going to survive contact with reality.

The Grenadier, priced at $80,000, runs a BMW B58 turbocharged inline-six, the same engine family used in current Toyota Supras, paired with a ZF 8HP eight-speed transmission rated to handle roughly 1,000 horsepower stock. Carraro heavy-duty beam axles and locking differentials front, center, and rear round out a drivetrain built for real off-road abuse, not parking-lot styling.

Inspecting a new car by cutting a hole in it

On the lift, the underside matched the reputation: thick skid plates, sturdy coils, tie rods substantial enough to impress the crew on sight. That inspection didn’t stay observational for long. Curious what the B58 would sound like unrestricted, the team took a power saw straight to the rear muffler while the car sat on the lift, cutting the exhaust off entirely within the same outing the car was picked up in. “Keeping it nice” was already more of a bit than a plan.

Crushing a Volkswagen Beetle and climbing a hill wide open

Out at the property, testing got physical fast. The Grenadier’s first off-road test involved deliberately crawling over a parked Volkswagen Beetle, crushing the roof and body panels under its weight while the crew checked how the suspension and locking differentials handled it. Cody called the truck genuinely capable off-road, for whatever that was worth to an interior that had already outlived its clean-and-original phase.

The bigger test came next: a full-throttle hill climb, accelerator pinned to the floor. It made the climb, but not cleanly. Thick smoke and a strong burning smell poured from under the hood almost immediately after, the exact cause never definitively identified on camera.

A fire extinguisher problem that became an interior problem

The response to that smoke escalated fast. A fire extinguisher went off into the engine bay, then a second one discharged inside the cabin, blasting dry chemical powder through the vents and across a dashboard that had been factory-fresh barely an hour earlier. Rather than carefully cleaning it up, the crew grabbed a garden hose and started flushing the interior directly, which predictably turned into a full extinguisher fight between crew members, more powder going off both inside and outside the truck. By the time anyone called a truce, the Grenadier’s cabin had been hosed down, powder-coated, and treated like a prop rather than an $80,000 new vehicle.

The joke was the plan all along

Cody wrapped the video by confirming the smoke had come from the engine bay, without further explanation, then delivered the actual point of the whole thing: he’d bought a bright red Grenadier specifically to keep it nice, had no plans for it, and this would be the only video he ever made about the truck. Given everything that preceded that line, the sincerity of it was never really in question.
