Twenty years after killing the SRT10 Viper truck, Ram is back with something even more unhinged. The 2027 Ram 1500 Rumble Bee lineup arrives with four HEMI V8-powered variants, and the top-spec SRT puts 777 horsepower to the ground. This is not a concept. It is a production truck.

The Rumble Bee SRT runs the 6.2-litre supercharged Hellcat HEMI, the most powerful internal combustion engine ever dropped into a production pickup. The numbers are violent: 0-60 mph in 3.4 seconds, the quarter mile in 11.6 seconds at 116 mph, and a targeted top speed of 170 mph. That last figure demanded a front splitter, functional aero hood, and an 80mm rear spoiler working together to generate 192 pounds of downforce at speed.

Four Trucks, One Very Clear Point

The lineup runs across genuine performance steps:

Rumble Bee: 5.7-litre HEMI V8, 395hp, 0-60 in 6.1 seconds
Rumble Bee 392: 6.4-litre HEMI V8, 470hp, 0-60 in 5.2 seconds
Rumble Bee 392 Track Pack: Same engine with aero upgrades, semi-active Bilstein Damptronic shocks, and Brembo six-piston front brakes
Rumble Bee SRT: 6.2-litre supercharged Hellcat, 777hp, 680 lb-ft of torque, same Brembo stoppers and 325mm rear rubber

Every variant gets a flat-bottom steering wheel, console shifter, paddle shifters, and a physical RWD button to fully disconnect the front axle. The top two add launch control and an electronic spool function for burnouts on demand.

A Short Truck Built to Handle Like It Hates You

Ram pulled 13 inches out of the standard 1500 wheelbase, cutting frame flex by 10 percent. The result is a Quad Cab short-bed combination sitting 219.5 inches long and 88 inches wide. That width pushed the track out 6.8 inches up front and 7 inches at the rear versus a stock Ram 1500, giving the SRT a stance wide enough for 325/40R22 tyres on 22x12-inch wheels. The only production vehicle Ram has fitted with wider rubber is the Dodge Viper.

Towing capacity holds at 8,890 pounds across the lineup. This thing still works as a truck.

When Does It Land?

The base Rumble Bee with the 5.7-litre HEMI reaches production in late 2026 from Stellantis's Saltillo facility. The 392 and SRT variants follow in the first half of 2027. The muscle truck segment sat empty for two decades. Ram just filled it hard.
