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.

Stellantis will enter joint venture with Samsung SDI for EV batteries

SEOUL — South Korean battery maker Samsung SDI Co Ltd and global automaker Stellantis NV have agreed to jointly produce electric vehicle (EV) batteries for the North American market, a person familiar with the matter said on Tuesday. Samsung SDI, an affiliate of South Korean tech giant Samsung Electronics, already has EV battery plants in South Korea, China and Hungary, which supply customers such as BMW and Ford. "The two companies (Samsung SDI and Stellantis) have struck a MOU (memorandum of understanding) to produce EV batteries for North America," the person with knowledge of the matter told Reuters. The source spoke of condition of anonymity because of the sensitivity of the matter. The person said the location of the battery joint venture is under review and will be announced later. In July, Reuters reported that Samsung SDI may build a battery plant in the United States, citing a company source. South Korea's Yonhap news agency earlier reported the two companies plan to build a factory in the United States, citing industry sources. Samsung SDI and Stellantis did not have immediate comment when reached by Reuters. Stellantis on Monday struck a preliminary deal with battery maker South Korea's LG Energy Solution (LGES) to produce battery cells and modules for North America. Shares of Samsung SDI were up 2.6% as of 0300 GMT, versus a 0.6% rise in the KOSPI benchmark index.

Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.
