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.

Driving the Panamera and Mike's Rant | Autoblog Podcast #487

This week we cover some recent news like the upcoming Land Rover Discovery, updates to FCA's large car platform (including the Challenger), and talk about water injection. Then we go into what we've been driving - David just finished his time in the Porsche Panamera Turbo and Mike tried the GMC Acadia. And then Mike (who is still uncomfortable writing in the third person) goes on a rant about why automakers shouldn't specify which cars are aimed at women. The rundown is below.

2018 Jeep Grand Cherokee Trackhawk is more expensive than the Dodge Demon

Jeep has finally released pricing for its crazy, all-wheel-drive, Hellcat-powered Grand Cherokee, and it's seriously expensive. It starts at $86,995. That's a full $2,000 more than the limited-production, 840-horsepower Dodge Challenger SRT Demon. For 140 fewer horses, and a quarter-mile time that's 2seconds slower (11.6 seconds vs. 9.6), you'll spend more money. Then again, the Grand Cherokee can do things the Demon and the Hellcats can't. It's got more space than any of them, meaning you can carry quite a bit more. It's capable of towing up to 7,200 pounds of stuff. It also has all-wheel drive, which means you have a little extra traction in bad weather, and you have the opportunity to do spectacular four-wheel burnouts. And of course, the Trackhawk is still fast and capable by any measure. It's only a tenth of a second slower to 60 mph than the Challenger Hellcat Widebody. It also comes with massive Brembo brakes, with the largest front rotors fitted to a Jeep, to haul it down from 60 mph in a claimed 114 feet. Each corner features 295-mm tires that Jeep claims let the Trackhawk generate 0.88g circling a skid pad. If the Trackhawk sounds like just the absurd performance machine you've been waiting for, you'll be able to put your order in soon. Dealers will accept orders starting Aug. 10, and the vehicles will start arriving at dealer lots toward the end of the year.
