The 2027 Ram 1500 Rumble Bee lineup has generated plenty of attention since Ram pulled the wraps off its new street-performance truck family. Now, while Ram engineers continue putting the upcoming models through their final development work, we happened to spot a particularly interesting pair of prototypes during our daily travels around Metro Detroit.
Both Rumble Bees were sitting on the back of a car hauler. The rear truck appeared to be a black Rumble Bee SRT development mule with Hurricane High-Output badges from the RHO, while the truck sitting directly in front of it looked to be an earlier Rumble Bee 392 Track Pack mule.
Seeing the two together provided an interesting look at just how far development of Ram’s new muscle truck has come.

Two Very Different Development Stages
The Rumble Bee SRT sitting at the rear of the transporter looked considerably closer to production form. The 392 Track Pack mule in front of it was a completely different story.
The biggest giveaway was its front fascia.
Instead of a finished production piece with proper grille inserts and mesh, this truck appeared to be wearing a 3D-printed prototype fascia. Stellantis regularly uses 3D-printed components during vehicle development because engineers can quickly produce and revise parts without waiting for expensive production tooling.
Up close, the unfinished nature of this one was easy to see. Large bands ran through the grille openings to help reinforce the fascia, while the normal production-style inner grille pieces were nowhere to be found.
The truck was also riding on non-production wheels, another common sight on engineering vehicles.
Seeing the rougher 392 Track Pack mule sitting directly ahead of the more finished-looking SRT really showed the progression these trucks have gone through during development.

Ram’s New Street Muscle Truck Formula
The Rumble Bee is considerably different from Ram’s recent performance trucks. Rather than focusing on lifted suspension, oversized off-road tires, and desert-running capability, the Rumble Bee is being developed specifically for pavement.
Ram shortened the wheelbase by 13 inches and uses a Quad Cab configuration with a 5-foot, 7-inch bed. The body measures a massive 88 inches wide, giving the truck a planted widebody appearance.
The lineup starts with the 5.7-liter HEMI V8 producing 395 horsepower and 410 lb-ft of torque. Above that sits the naturally aspirated 6.4-liter HEMI-powered Rumble Bee 392 with 470 horsepower and 455 lb-ft.
The 392 Track Pack takes that package a step further with additional performance hardware, SRT-inspired styling, and track-focused electronics.
Sitting at the top is the Rumble Bee SRT and its supercharged 6.2-liter HEMI HELLCAT V8. With 777 horsepower and 680 lb-ft of torque, Ram says the flagship truck can run from 0–60 mph in just 3.4 seconds and reach 170 mph.

The Rumble Bee Is Already Getting Attention
There are already signs that Ram’s street-truck gamble is working.
The first allocation of the 5.7-liter Rumble Bee reportedly sold out only 90 minutes after ordering opened. UFC President and Ram spokesman Dana White also made headlines after purchasing a pair of one-of-one Ram performance trucks for $1.5 million at the Barrett-Jackson Las Vegas auction, including VIN 001 of the Rumble Bee SRT.
It’s another indication that the modern muscle truck formula being pushed by Stellantis Head of the Americas Tim Kuniskis is attracting attention.
The Rumble Bee 392, 392 Track Pack, and Rumble Bee SRT are scheduled to arrive during the first half of 2027.
Seeing these two development mules side-by-side offered an unusual look at the process behind getting there. One still carried obviously unfinished prototype hardware, while the other looked considerably closer to the truck customers will eventually see on the street.
