2021 Ram 1500 TRX Suspension Deep Dive | Underbelly of the beast

I think we can all agree that we have been waiting for a gonzo full-size truck like the 2021 Ram 1500 TRX for a long time. After all, it has been over a decade since the Ford F-150 Raptor came out, and it was such an immediate hit that I expected its direct competitors to respond much sooner than this. We all knew something was finally brewing in 2016, when the TRX concept was unveiled at the Texas State Fair. I was there, and was among the many who gave the assembled Ram higher-ups an enthusiastic thumbs-up. That’s what they were hoping to see before they greenlit the project. The pace of development being what it is, and with the redesigned, current-generation Ram 1500 a prerequisite that understandably had to come first, itÂ’s no surprise that weÂ’re only seeing it now as a 2021 model. You may be biting your tongue that I overlooked the Tundra TRD Pro or the Chevrolet Silverado Trail Boss, but neither of those comes close to following the formula established by the Raptor: big engine, a much wider stance than the base truck, greatly enhanced suspension travel, huge tires and swollen fenders to cover it all. Only the Raptor and the TRX fit that mold. For now.   Before I got started, I first pointed the TRX up my RTI ramp and measured its Flex Index score. Please excuse the shaded nose; the truck ran farther up than IÂ’d guessed and literally drove out of the picture. But something in my subconscious warned me to keep the garage door open, which was fortuitous because the nose of the Ram ended up inside. The TRX hiked its front wheel 29 and 7/8 inches off the ground before the left rear tire reached the point of lift-off, and that equates to a climb of 87.4 inches up the deck of my ramp. Divide that by the TRXÂ’s wheelbase of 145.1 inches, multiply by 1,000, and you arrive at a Flex Index score of 602 points. It could have been a few points higher, I think, if I could have straightened out the steering a bit better. But the high-grip cheese grater surface of my ramp was firmly dug in and having none of it. This is an extremely good score for a full-size crew cab pickup. LetÂ’s take a closer look at what made that possible.   The track width of the TRXÂ’s double wishbone front-suspension is a full 6 inches broader than a regular Ram 1500, and you are looking at the parts that are responsible. The lower wishbone (yellow arrow), the upper control arm (green) and the steering knuckle (red) conspire to add 3 inches per side to the TRXÂ’s stance.

Chevy says not to look at the 2019 Silverado's fuel economy rating

The 2019 Chevy Silverado is hitting dealerships soon, and one of the most notable changes for the new full-size pickup is the addition of a 2.7-liter turbocharged inline-four. The engine replaces the naturally-aspirated 4.3-liter V6 in volume consumer models like the Silverado LT and promises more power, less weight and — most importantly — better fuel economy. The thing is, the gains in efficiency haven't been as dramatic as some might have hoped, especially when stacked up against competitors from Ford and Ram. As Automotive News reports, GM's response is a little murky. First, let's talk numbers. We're pulling all figures from FuelEconomy.gov, the official U.S. government source for fuel ratings. Fuel economy numbers on trucks vary greatly based on a number of factors. Bed and cab configuration play a part, but so does a four-wheel-drive system. You also have to factor in tires, transmissions, rear-axle gearing, hybrid systems and cylinder deactivation. Things like that can make the difference between best- and worst-in-class. The EPA's website doesn't give enough information a lot of the time, so there's really no easy way to compare apples-to-apples. First, take a look at the ratings for the 2019 Silverado. A 2.7-liter model with two-wheel drive is rated 20 city, 23 highway and 21 combined. That's both better and worse than a two-wheel drive 2018 Silverado with the 4.3-liter V6 (18 city, 24 highway and 20 combined). The updated 2019 Silverado with a 4.3-liter V6 has yet to be rated. With less weight and a smaller engine, many hoped Chevy would make bigger gains. It's unusual to see any decrease in a fuel economy metric these days. GM says that it's not done tuning the new 2.7-liter engine, so fuel economy could theoretically increase. Expanding further, a V8-powered 2019 Silverado (17 city, 24 highway and 19 combined) actually gets better highway fuel economy than a turbocharged four-cylinder powered truck in certain configurations, even if the latter has a better overall average. But that's only with two-wheel drive, the 8-speed transmission and cylinder deactivation. A Silverado with the 5.3-liter V8 and a 6-speed automatic is rated at 15 city, 22 highway and 17 combined. The biggest issue with the Silverado 2.7-liter doesn't come from within GM itself but from Ford and Ram. GM cites the Ford F-150 with the 3.3-liter V6 and the Ram 1500 with the 3.6-liter V6 as the closest competitors to its new 2.7-liter inline-four.
