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.

eBay Find of the Day: 1977 Jeep J20 time capsule

Is it just us or has eBay really become, of late, a surprising time capsule of older, barely used automobiles? We've had the 2005 Porsche Carrera GT with 83 miles, the 2004 Ferrari Enzo with 175 miles, the 1987 Shelby Lancer with 22 miles, the 1989 Shelby Dakota with 23 miles - none of those four cars ever even registered - and the 1975 Cosworth Vega with 191 miles. You can add to that list a 1977 Jeep J20 - the kind of Jeep that enthusiasts point to when they beg the brand to make another pickup truck.
Listed on eBay by Masterpiece Classic Cars in Whiteland, Indiana, the Brandywine and Alpine White truck has used its 360-cubic-inch V8 paired with a three-speed automatic to go just 3,940 documented miles. Not surprisingly, it's listed in excellent condition and the images appear to bear that out. The three-quarter-ton pickup comes with its original manual and pamphlets, the Quadra-Track four-wheel drive probably just as ready to tackle the terrain as it was 36 years ago. If only it came with some John Denver to play in that AM/FM/8-Track stereo...
At the time of writing it hasn't garnered a single offer or bid, probably due to the above-top-dollar Buy It Now price of $34,900. Still, since this is likely the closest you'll get to a Jeep pickup for some time, we'd recommend admiring it in the gallery of photos above.

2014 Jeep Cherokee: Introduction

When we look back at some of the more shocking product launches of recent yeras, the Jeep Cherokee is certainly high up on the list. And we aren't just talking about its off-the-wall, polarizing design.
For starters, it brought back the iconic Cherokee nameplate - something Jeep enthusiasts have coveted for ages. But beyond that, it brought a new evolution for the Jeep brand. After all, the Cherokee is car-based - using the same compact platform that underpins the Dodge Dart and Chrysler 200. It has a greater focus on technology and refinement than ever before, in an effort to appeal to a new crop of Jeep customers. And powering it all is a new (optional) V6 engine paired with an equally new nine-speed automatic transmission.
Can the Cherokee's car-based roots still allow for a vehicle that's superb when the going gets tough? Will its design still be a love/hate affair in one year's time, or will it start to blend in? Is the powertrain strong enough to not only support the needs of daily driving and road trips, but blaze a few trails as well? We're aiming to answer all these questions, and more, over the next 12 months. Welcome to the Autoblog long-term garage, Cherokee.
