A beast-like snarl snorts beyond the crest of a muddy ORV trail, but this is no ordinary wild animal or hog, it's the furiously quick 702-hp Ram 1500 TRX. Under the hood, a powerful supercharged 6.2-liter V-8 sucks up fuel as if it were drinking from a garden hose. An eight-speed automatic transmission handles gear shifts and the truck's four-wheel drive system carries this enormous off-road animal in even the most treacherous places. The TRX only has two predators to look out for: the 700-hp Ford F-150 Raptor R and the quickest truck we've ever tested, the all-electric Rivian R1T. Unfortunately, time has run out for the mighty TRX, as Ram announced 2024 as its final year. Hiding between the TRX's bulging fenders and below its scooped hood is a supercharged 6.2-liter Hemi V-8. More popularly known as the Hellcat engine, this specific version produces 702 horsepower and 650 pound-feet of torque, which is sent to all four wheels through an eight-speed automatic transmission. During our testing, the TRX shot to 60 mph in just 3.7 seconds and completed the quarter-mile in 12.3 seconds at 110 mph. That makemodels it the quickest pickup we've ever tested. Despite its hefty curb weight and huge footprint, the Hellcat-powered Ram is surprisingly refined and easy to handle on paved roads. Still, its supercharged V-8 is ready to emit exciting sounds from its exhaust pipes. Of course, the TRX is meant to play in the mud, rocks, and sand too. Along with a reinforced steel frame, it boasts a beefed-up suspension built to bend and bound with more than 13 inches of travel. It rolls on a set of massive 35-inch all-terrain tires mounted on 18-inch wheels that contribute to the truck's 11.8 inches of ground clearance. Ram says the half-ton Hellcat can also ford up to 32 inches of water. Every TRX comes with enough underbody plating to protect a Brink's truck, Bilstein remote-reservoir dampers, an electronic-locking rear differential, and gigantic 15.0-inch front brakes.
