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.

Build a Jeep Gladiator 392 next? The Hummer H3T Alpha blazed the trail

The 2021 Wrangler Rubicon 392 will combine the go-anywhere capability of a Jeep's iconic off-roader with the grunt of a V8 for the first time in decades. As cool as that is, we can't help but think Jeep is missing out on a huge opportunity to pair that 470-horsepower, 6.4-liter Hemi V8 with the Wrangler's pickup cousin, the Jeep Gladiator, in the form of a Mojave 392.  Autoblog took part in a media Q&A session with Jeep ahead of the Rubicon 392's announcement in which the company's product higher-ups said that there are currently no official plans to build a 392 variant of the Gladiator pickup. But whether or not Jeep has plans, it certainly has precedent, and from our perspective, a market.  Rewind to 2008, better known as one of the worst possible years to introduce a gas-guzzling, V8-powered pickup truck. Enter the 2009 Hummer H3T Alpha, the first variant of Hummer's midsize truck/SUV hybrid to be offered with a 5.3-liter V8. The 300-horsepower small-block was an upgrade to the sturdy but relatively uninspiring 3.7-liter inline-5 that the H3 lineup had inherited from its midsize pickup platform mates.  As our Jeremy Korzeniewski noted in the Rubicon 392's introductory piece, an open-top Jeep has not been offered with an optional V8 for as long as the "Wrangler" nameplate has existed. The last Jeep 4x4 to do so was still a CJ, or civilian Jeep, and the 304 cubic-inch engine came from American Motors Corporation. Incidentally, this generation of the Wrangler is also the first to be offered in a pickup variant. Cue the beard-stroking.  Now, frankly, it's not even remotely fair to compare the H3T's powertrain offerings to the decade-newer Gladiator's, but the Hummer actually boasts a few advantages over Jeep's modern pickup. While most of the Jeep's off-road specs give it an edge, the Gladiator doesn't come close to the H3T's 30.1-degree departure angle, for instance. And in more practical terms, the stubbier H3T has other maneuverability advantages. The Gladiator has 3" of wheelbase and 5" of overall length on the H3T, and a 22.4-foot turning radius to show for it. The Hummer's? Just 18.5'.

5 classic trucks and their polarizing modern revivals

EVs are helping eliminate Detroit's gas-guzzling problem. Some revivals of gas-powered classics are getting the EV treatment.  But not every revived model looks exactly like its original counterpart. We're in a new era of hulking Detroit metal, and you can thank EVs. Americans can't get enough of their big, beefy trucks and SUVs. But for many years, some of the biggest gas guzzlers fell out of fashion as gas prices rose and emissions regulations tightened. But in the past few years, some of the most iconic American truck nameplates have been brought back to life with electric motors, like the GMC Hummer. In other cases, as with the Ford Bronco, improvements in engine technology and more interest in rugged adventure vehicles made a gas-powered revival possible. Even some revivals that started as gas-powered, like the Chevy Blazer and the Jeep Wagoneer, are now getting electrified spinoffs. (Even if they don't always look quite as sleek as their original inspiration.) Here are side-by-sides of five classic American trucks and their modern counterparts. The Jeep Wagoneer 1975 Jeep Wagoneer and 2024 Electric Jeep Wagoneer SStellantis After a long wait, Jeep released its revival of the classic Wagoneer and Grand Wagoneer in 2020. Starting later this year, an electric version of the luxury Jeep SUV will join the Wagoneer lineup. The Chevrolet Blazer A 1973 Chevrolet Blazer and a 2024 Chevrolet Blazer EVGetty Images, General Motors The Chevrolet Blazer was first rebooted in 2019 as a sporty family SUV. The modern Blazer shares zero resemblance to its boxy, off-roading older sibling, but it has still managed to become one of Chevy's more popular SUVs in recent years. The Blazer EV came later, and was one of the first models GM built on its new Ultium battery platform. The Hummer A Hummer H2 and the 2023 Hummer EV pickup truckGetty Images, General Motors Once the poster child for Detroit's big, bad gas guzzlers, the Hummer got new life as an electric pickup truck in 2021. The Ford Bronco A 1971 Ford Bronco and a 2022 Ford BroncoFord Motor Co. After a rouge group of engineers and designers inside Ford spent years trying to breathe life back into the Blue Oval's boxy off-roader, the Ford Bronco was finally resurrected in 2020 amid a rise in popularity for rugged adventure vehicles.
