2022 Ram 1500 TRX Off-Road Test | High atop Mt. Ridiculous

I slide to a quick stop on the mud-slicked trail. Up ahead, a pair of trees on either side force the track into a pinch point, one narrower than I was expecting. A Wrangler looks like it’d pass through with ease, but IÂ’m driving the 2022 Ram 1500 TRX, the widest off-road truck in the business. I eyeball the gap with some apprehension as a fellow off-roader pulls up to me in their side-by-side.  “We typically fit our full-size trucks through that gap,” he assures me. I gesture at the TRX, which is essentially a full-size truck in ultra-wide panorama mode, and voice my width concerns in return. Still, his confidence gives me some resolve, and I decide to trust the park regular and send it. And by send it, I mean idle along slowly watching each side of the truck — itÂ’s a long way over to the passenger side corner — to ensure I donÂ’t return RamÂ’s test truck with slightly narrower fenders than when I received it. Ultimately, the strangerÂ’s advice proved itself, and I just made it through the gap and onward to the next part of the trail where I promptly crashed through a big ‘ole mud puddle with a triumphant V8 bellow.  Big ‘ole mud puddles are the main source of entertainment at The Mounds ORV Park, too. There are all sorts of different sizes and depths for you to try out, which is exactly what I did with the 702-horsepower TRX, trusting its 32-inch wading depth to be my friend for the day. The TRX hardware is firmly in the realm of absurdity, allowing it to attack just about any terrain or surface – assuming it can physically fit through. The 6.2-liter supercharged V8 supplies 650 pound-feet of torque to all four wheels that lets it power out of mud and muck by aggressively flinging it skyward as though it has a vendetta against both the sky above and Earth below. This sort of driving is best done in Mud/Sand mode, as it sets the four-wheel-drive system, throttle response, transmission, suspension and steering into their ideal settings to have the most fun in the slick stuff. It works as advertised. Going 0-60 mph in 4.5 seconds in a truck so large is already a mind-altering experience, but having the traction and ability to properly launch off-road is where the TRX truly sets itself apart. Those 35-inch Goodyear Wrangler Territory all-terrain tires, developed specifically for the TRX, dig into the mud and dirt, shooting you forward with far less scrambling and scrapping for purchase than youÂ’d expect from such a sloppy surface.

500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.

Ram 1500 TRX too tame for you? Hennessey cranks its Hemi V8 to 1,012 horsepower

Ram captured the top spot on the horsepower podium when it released the Hellcat-powered 1500 TRX in 2020. The truck's 702-horsepower output places it comfortably ahead of the Ford F-150 Raptor, at least for now, but American tuner Hennessey saw plenty of room for improvement. It added over 300 horses to the TRX's cavalry. Hennessey is a master in V8-ology, so it was only a matter of time before it injected more power into the TRX. It announced two models named Mammoth 900 and Mammoth 1000, respectively, and each number vaguely corresponds to the V8's new output. The 900's 6.2-liter produces 912 horsepower and 873 pound-feet of torque, increases of 210 and 223, respectively, compared to the standard TRX. Hennessey achieved these figures by upgrading the supercharger pulleys and making relatively basic changes to the intake and exhaust systems. Stepping up to the 1000 unlocks 1,012 horsepower and 969 pound-feet of torque, numbers that give the 6,300-plus-pound truck the uncanny ability to reach 60 mph from a stop in 3.2 seconds. It flies through the quarter mile in 11.4 seconds at 120 mph. Building a pickup with supercar-like acceleration required installing a bigger, 2.65-liter supercharger, adding high-flow fuel injectors, and recalibrating the ECU. Intake and exhaust modifications are on the menu, too. Surprisingly, it doesn't sound like Hennessey made significant internal changes to the engine or to the transmission, which suggests the standard components can handle a massive amount of power. Context is useful here. Released in 2013, the fifth and final generation of the Dodge-turned-SRT-turned-Dodge again Viper took 3.3 seconds to sprint from zero to 60 mph, and it logged an 11.5-second quarter-mile time. Previewed in a computer-generated sketch, the Mammoth 1000 (shown above) also receives 20-inch wheels wrapped by 35-inch off-road tires, a 2.5-inch suspension lift, custom bumpers on both ends, extra LEDs up front, electronic fold-out steps, plus an array of model-specific emblems. Inside, Hennessey added a numbered plaque. 200 units of the Mammoth 1000 will be available for the 2021 model year, and pricing starts at $135,350 including the cost of the donor truck (which carries a base price of $71,790) and a warranty valid for two years or 24,000 miles. Put another way, you get 30.6% more power than stock for about 40% more money.
