Hennessey Mammoth 1000 6x6 TRX is prehistoric excess

A few things have changed on the way to the Hennessey Mammoth 1000 6x6 TRX, the six-wheeled pickup based on the 2021 Ram 1500 TRX announced in September 2020. Back then, it was going to be powered by the 7.0-liter Hellephant engine, tuned from a stock 1,000 horsepower to 1,200 hp, it would cost $500,000 before customization, and the Texas tuner said there'd only be three built — likely owing to the exceeding scarcity of that crate motor. The good news for folks who thought they'd be left in the cold is that a slightly different but still astonishingly massive Mammoth is going into serial production, and at a lower price. Instead of the Hellephant, a 6.2-liter Hellcat lives under the chest-height hood. In the Ram 1500 TRX the engine makes 702 hp and 650 lb-ft., but a 2.65-liter supercharger is the heart of a Lone Star State overhaul boosting output to 1,012 hp and 969 lb-ft. The rest sticks to the original formula. The lengthened frame stretches overall length to 283 inches, a skosh more than four feet longer than the donor truck — long enough to hold plywood and a picnic in the bed. A Bilstein suspension hangs all that sheetmetal seven feet high over 20-inch wheels wearing 37-inch Toyo Open Country rubber. If for some reason the six-toed contact patch doesn't get a driver out of trouble, the third axle can be locked up. In case of greater calamity, the stinger front bumper is ready to accept a winch, and the rear bumper sprouts a couple of attachment points. There are also footholds in that rear bumper to make rummaging in the bed easier, but those footholds are so high up they could use the same retractable steps alongside the cabin to reach. Naturally, the interior has been reworked, and there are a "dazzling array of LED lights." Hennessey says it will make 12 of these — the largest truck in the company's 30-year history — every year. The Mammoth 6x6 can be ordered directly from Texas or at any authorized Ram retailer for $449,950. We can't wait to see what happens when this meets the GMC Hummer EV pickup on the trail. If you like the idea of the Mammoth but this Mammoth is a tad too mammoth, consider the rest of Hennessey's family of Elephantidae, the four-wheeled Mammoth 900 and Mammoth 1000, or the Mammoth SUV.   Related video: This content is hosted by a third party.

Daily Driver: 2015 Ram ProMaster Cargo

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, reviewed by the staffers who drive them every day. Today's Daily Driver features the 2015 Ram ProMaster Cargo, reviewed by Seyth Miersma. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. Show full video transcript text [00:00:00:00] I'm in a vehicle that really kind of belies the name of this video series, Daily Driver. This is the 2015 Ram Promaster Cargo Van. I'm in the high roof extended length version of it. You can see that it's got an empty cargo bay behind me. It's a little strange because what I'm doing right now is commuting in it, which is definitely not what this van is made to do. The single strongest attribute of the Promaster [00:00:30:00] package that I found was its maneuverability at low speeds in and around town. That wasn't really something that I expected. I knew from driving the rest of the big vans in this segment. I've been in various Sprinters over the years, although not the brand new one, and I put a lot of miles actually on a Nissan NV. They're all meant to be more nimble than they would seem from their exterior, but the Ram just feels kind of a class above. It turns on a dime. It's really, really easy to [00:01:00:00] pull up close to a curb or another car and be able to just get in and out of a space with very little room around you. I had no problem getting up to speed with the rest of traffic. Merging and passing aren't really an issue. Sometimes you'll hear her struggle a little bit if you really put your foot in and you're trying to get around somebody, but that's just wind resistance and curb weight man, that's too be expected. Another aspect that I was really impressed with with the Promaster is the 3.6 [00:01:30:00] liter V6 engine, both in terms of its performance and its economy. It's putting out out 280 horsepower, 258 pound-feet of torque. It's a huge van. It's not quick. The cargo area back there is really nice. Not only is it tall enough that I can stand up in it. I mean, this vehicle is close to nine feet overall from the exterior dimensions. Access to the cargo area is just as easy as you would hope for too. You got a big, big sliding door over here. The rear doors open completely [00:02:00:00] flat so that it's easy to both maneuver and to get stuff in and out, obviously. The load floor is pretty low. Easily accessible. You've got the Uconnect screen with the nicer head unit.

Ram/Jeep Ecodiesel engine has Maserati roots

The 3.0L turbodiesel V6 in the 2014 Ram 1500 EcoDiesel earned a slot on Ward's Automotive 2014 10 Best Engines for its power, fuel economy and refinement. In a piece looking at how Fiat subsidiary VM Motor developed the engine, Ward's also makes note of the fact that the same lump goes in diesel versions of the Maserati Quattroporte and Ghibli. They're tuned a bit differently, naturally, with the QP putting out 275 horsepower and 442 pound-feet of torque, the smaller, lighter Ghibli making do with the same number of horses but a lower torque output of 420 lb-ft.
The 240 horsepower and 420 pound-feet put out by the oil-burning six-cylinder in the Ram was tamed with a host of advances, but it appears that Ram hasn't tamed demand: the initial allocation of 8,000 engines was spoken for within three days of the truck going on sale. Head over to Ward's to read the story of how Ram worked out the equation light-duty-pickup + diesel = success.
