Jeep mixed a CJ, a TJ, and a JK to make this sweet retro CJ66

What do you get when you mash-up a CJ and two Wranglers? Jeep calls it the CJ66, its concept for the 2016 SEMA show. It's a Frankensteined machine done right, another in a long line of fantasies from the back rooms at Jeep. A lot of donor vehicles were sacrificed for this one. The body came from a 1966 Jeep CJ – hence the name – and then was modified to fit on a Jeep Wrangler TJ chassis. The finishing touches, such as the bumpers and lights, come from the current Wrangler JK, and the hood was modeled after a JK's, too. The CJ66 has plenty of other neat details throughout as well, such as the vintage-style V8 badges on the fenders, the chains on the dropdown tailgate, and the custom hood latches. Also, like several other FCA SEMA concepts this year, it gets a pair of Dodge Viper seats. We're suckers for Viper seats. View 17 Photos The custom body also hides some impressive off-roading gear. There's a Warn winch tucked behind the front bumper, as well as an on-board tire inflation system, which makes it easy to deflate and inflate tires as the terrain requires. The truck also has 35-inch off-road tires on readily available wheels, front and rear differential lockers, and a custom roll cage and rock sliders. As you may have guessed from the V8 badges, this CJ66 also packs an octet of pistons. The 5.7-liter Hemi engine (or 345 cu. in. for traditionalists) makes 383 horsepower, and was installed using Mopar's new engine swap kit. The engine is hooked up to a six-speed manual transmission that sends power to Dana 44 axles front and rear. We have a feeling it will handle just fine on the trails.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Inline-6 Hemi replacement on the cusp of production from Stellantis

It appears that Stellantis is ready to put its long-rumored inline-six into production at its Saltillo, Mexico plant, possibly marking the beginning of the end of Chrysler's long-running 5.7L Hemi V8. But so far, the automaker's American brands have remained mum on where exactly the new turbocharged "Tornado" I6 may land. Stellantis powertrain blog Stellpower (by way of Muscle Cars & Trucks) spotted an entry for a new "GME T6" inline-six engine on the Saltillo facility's web site, suggesting that it was either in production or close to it. That entry has since been removed, but the mystery remains.  We've been hearing tidbits here and there about this new inline engine for years, but this is the first time we've seen anything suggesting its arrival is imminent. Usually, such a significant powertrain update would coincide with the launch of a new product to showcase it. So far, Stellantis has remained mum, even overseas, about where this engine is destined to reside. 2022 model year vehicles are likely off the table entirely.  But while it's common for new engines to debut with new cars and trucks, it's not a universal truth. Ford's Coyote V8 missed the corresponding Mustang refresh by a year, for example, orphaning the 2010 model and its much-needed styling updates with the old 4.6L V8 (and the 3.8L V6, for that matter; the 3.7L Duratec was also late to that party). Even sticking just to Stellantis, the JL Wrangler's powertrains have been a work in progress since it arrived back in 2018. The standard V6 and 2.0-liter turbo-4 debuted at launch; the EcoDiesel, 392 and 4xe all came later.  And 4xe may be the model by which to measure our expectations. Its introduction didn't come completely out of nowhere, but it was rather sudden for what turned out to be such a solid offering. That bodes well for the company's existing Hemi-powered trucks and SUVs. The Ram 1500, Jeep Grand Cherokee and Wagoneer are all strong candidates to receive the new Hemi replacement, as all would greatly benefit from even small improvements in fuel economy. If there's to be a future for the Dodge Charger and Challenger and Chrysler 300, they'd benefit too. And how about a Gladiator with the wick turned up, positioned as its equivalent to the Wrangler 392. Turn that Tornado into a Dust Devil. Don't worry; we've got plenty more where that came from.  Related Video This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
