Ram 1500 SRT TRX Outsprints Ford F-150 Raptor R at Hennessey

The Ram 1500 SRT TRX arrives with a supercharged 6.2-liter HEMI producing 777 horsepower (788 metric horsepower) — 57 hp more than the Ford F-150 Raptor R — and Hennessey Performance staged a head-to-head at its Pennzoil Proving Ground to see which factory production gas pickup is fastest.

Hennessey’s video and on-track runs form the basis of the comparison. The matchup paired the TRX against Ford’s 5.2-liter supercharged Predator V8 Raptor R, and the tests were run by Hennessey drivers Alex and Adam at the Sealy, Texas facility.

Spec sheets and claimed performance

Ford’s Raptor R is fitted with the 5.2-liter Predator V8 rated at 720 horsepower (730 metric horsepower) and 640 pound-feet (868 Newton meters) of torque. Ford’s published figures put the Raptor R at 0 to 60 mph in 3.6 seconds, a quarter mile in 12.0 seconds with a 113 mph (182 kph) trap speed, and a maximum speed governed to 114 mph (183 kph). The truck rides on 37-inch off-road tires and carries a curb weight of 5,950 pounds (2,699 kilograms).

The Ram 1500 SRT TRX returns after a production hiatus with the supercharged 6.2-liter HEMI V8 rated at 777 horsepower (788 metric horsepower) and 680 pound-feet (922 Newton meters). Ram’s figures list 0 to 60 mph in 3.5 seconds and a quarter mile in 12.2 seconds with a 114 mph (183 kph) trap, and a top speed limited to 118 mph (190 kph). The TRX is heavier, tipping the scales at 6,294 pounds (2,885 kilograms). Stellantis revived the TRX under new management following former CEO Carlos Tavares’s departure in December 2024; the truck’s return is part of that company decision.

On the first standing-start pass the two trucks launched aggressively. The Ford initially took a fragile lead but the Ram gained momentum and finished ahead; the Ford’s run was constrained by a speed limit reached at about 113 mph. In a separate roll race run in Sport mode the Raptor R appeared faster and held the lead through that particular run.

Both trucks were also tested in their off-road modes for high-speed desert-style runs. In that discipline, with dust trailing both pickups, the Ram 1500 SRT TRX prevailed. The Hennessey footage shows the heavier TRX using its additional output to overcome its weight in the staged comparisons.

The on-track sequence at Hennessey left the Ram TRX as the quicker truck in the standing start and off-road high-speed passes, while the Raptor R held advantages in specific roll-race situations.

The full set of runs and in-car footage are available in Hennessey Performance’s published video from the Pennzoil Proving Ground in Sealy, Texas, which records the staged comparisons and the exact sequences described above.
