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.

Auto critic calls out Corvette, Mustang and Cherokee faithful

Most automotive purists fear change, but not without reason. Change, after all, did kill big-block V8s, along with most station wagons and manual transmissions. But change has also brought with it far more performance, safety and fuel economy - not to mention ridding the world of shag carpet interiors, bias-ply tires and those horrible motorized seatbelts of the early '90s.
By this time next year, the Chevy Corvette, Jeep Cherokee and next-generation Ford Mustang will all be on sale and will all, in some way, have angered or offended purists. To those critics, Mark Phelan of the Detroit Free Press is preemptively telling them to stop complaining - at least until they've all been driven. From the Corvette's square taillights and the Cherokee's radical nose to whatever pony car purists will harp on the 2015 Mustang for, Phelan's column points out the positives of automotive evolution and the negatives of staying the course for too long. That's fair enough, but do you think Phelan is on point, or all wet? Head on over to the Detroit Free Press to read his words, then have your say in Comments.

Chrysler readying 20 Moparized vehicles for SEMA

The Las Vegas Convention Center has plenty of space for aftermarket companies and automakers to show off their wares, and it looks like Chrysler is taking advantage of the spacious floor plan. At next month's SEMA Show, Chrysler will have a full 20 cars from its six brands decked out with Mopar gear.
As a hint of what is to come, Chrysler released a handful of teaser sketches showing glimpses of modified Jeep Cherokee, Ram 1500, Fiat 500L and Chrysler 300 concept vehicles. The automaker will also use the venue to show off a new line of Jeep Performance Parts offered by the all-new Mopar Off-Road Division. In addition to the images, Chrysler also issued a brief press release - posted below - breaking down some of the "industry-first features" that Mopar has offered in recent years.
