Jeep Gladiator high-speed off-roader reportedly in development

Before the 2020 Jeep Gladiator was revealed, it seemed like there was a never-ending flow of tidbits leaking out about the truck. Now it's out, and while the flow has slowed, there are still interesting reports floating about. The latest comes from Jeep Gladiator Forum, which cites an anonymous inside source as saying there's a high-performance version of the pickup coming designed for fast off-roading similar to a Ford F-150 Raptor or Chevy Colorado ZR2. We reached out to Jeep regarding the possible truck, and a representative said the company had no comment. That's certainly exciting news if it turns out to be correct, but there are reasons not to get your hopes up just yet. The forum reports that the truck is in the early stages of development, and it's still being decided whether there's enough of a market for it. From our perspective, such a model is neither a dead end nor a shoo-in. Certainly there are people willing to buy fast off-roaders, as the aforementioned Raptor and ZR2 have shown. Also, Jeep has proven that people are willing to spend a lot on Wranglers, both from the factory and on aftermarket parts, so an even more expensive model wouldn't necessarily put people off. So those are two important points in favor of a fast Gladiator. Points against a fast Gladiator start with the existing Gladiator Rubicon. While it isn't necessarily designed for bashing dunes, it does come with a huge amount of trail-ready equipment already. It has differential locks and anti-roll bar disconnects, big tires and burly shocks. On slower trails, it may already be as capable as the Colorado ZR2, which would be the closest competitor to the hypothetical high-po Gladiator. And since the Gladiator Rubicon will be available with comparable engines to the ZR2, would something more potent be necessary? It would seem that to further differentiate, the Gladiator might need more power. That's certainly possible by way of a V8 transplant, but that would mean a lot of money spent on getting the engine to fit, making it reliable, getting it emissions compliant, and ensuring the drivetrain is strong enough. All those costs would make it harder to get approved. We may sound a bit pessimistic, but don't get us wrong, we would be excited to see a high-speed Gladiator, or any other Jeep for that matter. But we also want to be realistic, and there are certainly some significant hurdles to bringing such a truck to market. Related Video:

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.

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
