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.

25,000 Jeep Grand Cherokee, Dodge Durango SUVs recalled over brake feel

Chrysler has announced that it is recalling over 25,000 Jeep Grand Cherokee and Dodge Durango SUVs from several markets over concerns about brake feel under hard braking. The affected models are from the 2012 and 2013 model years, although the actual dates of production aren't available. 18,700 are in the US, while 825 are in Canada, 530 are in Mexico and a further 5,200 outside of North America.
According to a statement, Chrysler was informed of the issue by a component supplier for the Ready Alert Braking system, which primes the brakes in anticipation of an emergency stop. A component in the system was restricting the flow of brake fluid too much.
As Chrysler is quick to point out, the way the brakes functioned was in compliance with regulations and there are no reported cases of drivers losing braking power. Instead, the issue rests with what Chrysler calls a pedal feel that "was not consistent with customer expectations." So it would seem Chrysler is being proactive and fixing a problem not because there's a legal issue at work, but simply because it doesn't feel the way the manufacturer wants it to. Well done.

Chrysler touts Pacifica Plug-in minivan's lower emissions

Put the words "Chrysler" and "minivan" together, and the concept of lower greenhouse-gas emissions may not immediately come to mind – especially given today's news about FCA sister brands Ram and Jeep. Among mass-market automakers, Chrysler and its sister companies (namely Dodge and Ram) have long lagged its competitors in fuel economy, with little in the way of drivetrain electrification. Now, though, Fiat Chrysler says it's taking steps to make some green-vehicle progress via its new Chrysler Pacifica Plug-in Hybrid minivan. Namely, the automaker says the minivan, which can go 33 miles on electric power alone, generates 31 percent less emissions than previous-generation Pacifica, and 24 percent less than the 2017 model-year gas-powered variant. The Pacifica Plug-in, which will be the first hybrid minivan to be sold in the US, has a fuel-economy rating of 84 miles per gallon equivalent, and can go as far as 566 miles on a full tank and full electric charge. That full charge takes about two hours with a 240-volt charger, and 14 hours from a standard, 110-volt outlet. That means that over the lifecycle of the vehicle (estimated at 120,000 miles), the plug-in minivan, which will compete against models such as the Toyota Sienna and Honda Odyssey, may cut emissions by 21 metric tons of carbon dioxide relative to the gas-powered version. That is the equivalent to the annual emissions of about 22 US households, or, as Chrysler put it, 14 commercial flights to Los Angeles from Detroit. Chrysler is pricing the minivan at about $43,000 (or about $35,000 once the $7,500 federal tax credit for plug-in vehicles kicks in) and will start selling the model by the end of March.
