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.

What will Detroit do with the abandoned AMC headquarters?

As with so many other industrial and residential properties in Detroit, the former headquarters for the American Motors Corporation is having a hard time finding a reputable buyer. In October the Wayne County Treasurer held a tax foreclosure auction of 25,000 properties that included the AMC building, the starting bid being $500. Nicholas Casab won the building for $500, but the county voided the sale when Casab didn't pay the $232,000 in back property taxes. Detroit authorities haven't commented on the failed sale, but the city has until January 4 to decide if it wants to keep the building. If it doesn't want to hold onto it, the 1.5-million-square-foot property on 57 acres might be ceded to the Wayne County Land Bank Corporation. No matter who holds the deed come January 5, all anyone really wants is for someone to take possession of the building who will actually turn it into something useful and viable. The property opened in 1927 as a factory for the Kelvinator Corporation. Over the following decades, Kelvinator merged with the Nash Motor Company, and that merged entity merged with Hudson Motor Car Co, becoming American Motors. Chrysler took over the building in 1987 when it bought AMC, then shuttered it in 2009. The complex has produced refrigerators, Sikorsky helicopters, Jeeps, AMCs, and was used as an engineering center for Jeeps and other Chrysler products. Having been through several hands in the past six years, it is cited as part of the cycle of abandonment plaguing Detroit.

2021 Chrysler Pacifica First Drive | More features, better van

Ever since its introduction as a 2017 model, the Chrysler Pacifica has been one of our favorite minivans. It offers stylish looks inside and out, traditional minivan practicality, excellent infotainment and some of the most compelling powertrain options. For its 2021 model year refresh, the Pacifica smartly expands on all the things we already enjoyed and avoids ruining any inherent goodness, as evidenced by our test van, a new-for-'21 Pinnacle trim level. The Pacifica’s changes start on the outside with redesigned front and rear fascias. These changes are probably the least successful, by which we mean, theyÂ’re not bad, just different. The modest grille and simple bumper design have given way to a deeper main grille and large lower openings, plus a pronounced air dam. It gives the van a wider, lower and meaner look. We donÂ’t dislike it, but it seems different rather than better. We do like the revamped tail with its full-width taillights. And if for some reason you prefer the previous design, the entry-level Chrysler Voyager is just a decontented Pacifica with the old styling. Under the skin, the biggest change is the addition of all-wheel drive, something not shared with the Voyager. The feature has been absent from the Chrysler van lineup for several years, since Chrysler couldnÂ’t fit a driveshaft between the underfloor wells for the Stow ‘n Go second-row seats. That issue has been solved, and now you can have AWD without sacrificing any interior seating flexibility. The AWD system can send all power to the rear wheels as needed, and it also can disconnect the rear driveshaft to increase fuel economy. Our test Pacifica was equipped with all-wheel drive, and it was certainly effective in some of metro DetroitÂ’s snowy conditions, offering a bit more launch traction and some assistance powering out of slow corners. But in the dry, it doesnÂ’t change the driving experience at all. Also, despite the ability to disengage the rear driveshaft, fuel economy still takes a hit compared to the front-drive model, dropping from 19 mpg in town and 28 on the highway, to 17 in the city and 25 on the highway. That's a difference of 2 mpg combined, which works out to be $150 per year in annual fuel costs, according to the EPA.
