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.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.

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.
