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.

Fiat board makes Chrysler merger official, approves $5.4B bond sale

Fiat's board of directors has officially approved the merger plan that will see the conglomerate's automotive operations merged with Chrysler into the new Fiat Chrysler Automobiles.
The plan essentially provides a road map for the structure of the new company. It includes provisions for Fiat shareholders - one Fiat share will translate to one share of FCA common stock. The new company will also include a loyalty voting structure, which will provide for shareholders of Fiat stock or those that have held FCA stock for at least three years. According to the plan, these shareholders would see their voting power double, with two votes for every share of FCA's common stock. The overall merger plan still needs to be approved by the company's shareholders.
In other Fiat-related news, the company's board has announced a bond issuance of four billion euro ($5.4 billion). The new bonds should provide the company with a degree of flexibility in refinancing debts associated with the merger plan.

2015 Chrysler 200 snags EPA ratings of 18 mpg city and 29 highway

While Chrysler hasn't officially announced fuel economy figures for its new 200 sedan, the information for one model has just leaked out thanks to the US Department of Energy's FuelEconomy.gov website. It certified the 200 with the 295-horsepower and 262-pound-feet 3.6-liter Pentastar V6, nine-speed automatic and all-wheel drive as getting 18-miles-per-gallon city, 29-mpg highway and 22-mpg combined.
Last year's front-wheel drive 200 with a less-powerful version of the Pentastar was rated at 19-mpg city, 29-mpg highway and 22-mpg combined. That means that buyers are getting more power and all-wheel drive traction at almost no loss in economy. However, compared to current, all-wheel drive sedan competitors, the Chrysler comes in the middle. The Ford Fusion with all-wheel drive with the 2.0-liter EcoBoost four-cylinder has 240 hp and 270 lb-ft of torque is somewhat down on power but bests it in economy at 22-mpg city, 31-mpg highway and 25-mpg combined. The current Subaru Legacy 3.6R loses in both metrics with 256 hp and 247 lb-ft and a rating of 18-mpg city, 25-mpg highway and 20-mpg combined. However, Subaru claims the next generation with the same engine will boast 20-mpg city, 28-mpg highway and 23-mpg combined. But these numbers are just estimates from the automaker at the moment, and they haven't yet been certified by the EPA yet.
The numbers for the four-cylinder and front-wheel drive 200 drivetrains are not yet available, but Chrysler has been promising the sedan gets an estimated 35-mpg highway with the 184-hp and 173-lb-ft Tigershark 2.4-liter four-cylinder engine. We won't know for sure until it's certified, but we'll keep you posted.
