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.

Weekly Recap: GM scales back as Russian auto market teeters

General Motors' extensive plans to scale back its Russian operations are the latest sign the automotive market in the former superpower is collapsing – and there are few signs of recovery. GM said Wednesday it will stop selling mainstream Chevrolets and shutter the entire Opel brand in Russia. The moves leave GM with a luxury-focused presence consisting of Cadillac and Chevrolet's Corvette, Camaro and Tahoe. The cutbacks will be completed by the end of the year. The automaker will also idle its factory in St. Petersburg and end a contract-assembly agreement with Russian manufacturer GAZ. "We had to take decisive action in Russia to protect our business," Opel Group CEO Karl-Thomas Neumann said in a statement. "We confirm our outlook to return the European business to profitability in 2016 and stick to our long-term goals." GM is the latest automaker to scale back in Russia as the economic conditions, volatile currency and uncertainty over the conflict in the Ukraine all have sandbagged new car sales. Last month, vehicle sales collapsed 38 percent in Russia to 128,298 units, according to the Association of European Business, which records sales. Joerg Schreiber, chairman of the AEB automobile manufacturers committee, didn't even feign optimism in a statement announcing the figures. "The market is entering a very difficult phase now, and February is only the beginning," he said. "Industry sentiment is the next few months will be extremely difficult and the market bottom has yet to be found." The dovetails with industry experts, who predict the Russian auto sector will remain in the doldrums. IHS said earlier this year it expects Russia's sales to slip to just 1.8 million units in 2015, which is a 40-percent drop from 2012. Other News & Notes Chief leads Jeep's Easter Safari stable Jeep is bringing seven attention-getting concepts to Moab for its annual Easter Safari off-roading celebration in Utah, but the Chief is perhaps the standout of the group. It salutes the 1970s Cherokee with a throwback appearance and surfer styling cues. The Chief has a custom modified razor grille made famous by the Wagoneer, and it rolls on 17-inch slotted mag wheels. The surf theme comes in with ocean blue paint, floral cloth and leather seats and a tiki-style shifter handle. Based on the Jeep Wrangler, the Chief has removable sides, a 3.6-liter V6 engine and a six-speed manual gearbox.

Car Club USA: Moab Jeep Jamboree

Today Autoblog is excited to premiere its latest original video series, Car Club USA. Car Club USA's debut episode features the Just Jeeps club of Omaha, including a father-son duo traveling to Moab, UT to brave the treacherous trails. Brian is behind the wheel, as his father guides him through the most dangerous geographical features Moab's red desert has to offer. Joining them are Gene and Jean, an older married couple from Minnesota whose modified Jeep Wrangler – like its owners – knows no bounds. "We're in our seventies now," explained Jean. "We could be sitting at home in a rocking chair watching TV, but we'd rather do this." Also hitting the trails is Matt, a Californian who looks to pay homage to his father by exploring southern Utah in a World War II-era Jeep Willys. "This was our stomping ground," said Matt. "That's why I chose to come to Utah for my big vacation this year, in his memory, to see some of the places we used to go together, and have fun and do some Jeeping."
