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 ready to kill brands and fix U.S. problems, CEO Tavares says

  MILAN — Stellantis is taking steps to fix weak margins and high inventory at its U.S. operations and will not hesitate to axe underperforming brands in its sprawling portfolio, its chief executive Carlos Tavares said on Thursday. The warning for lossmaking brands is a turnaround for Tavares, who has maintained since Stellantis was created in 2021 from the merger of Italian-American automaker Fiat Chrysler and France's PSA that all of its 14 brands including Maserati, Fiat, Peugeot and Jeep have a future. "If they don't make money, we'll shut them down," Carlos Tavares told reporters after the world's No. 4 automaker delivered worse-than-expected first-half results, sending its shares down as much as 10%. "We cannot afford to have brands that do not make money." The automaker now also considers China's Leapmotor as its 15th brand, after it agreed to a broad cooperation with the group. Stellantis does not release figures for individual brands, except for Maserati which reported an 82 million euro adjusted operating loss in the first half. Some analysts say Maserati could possibly be a target for a sale by Stellantis, while other brands such as Lancia or DS might be at risk of being scrapped given their marginal contribution to the group's overall sales. Stellantis' Milan-listed shares were down as much as 12.5% on Thursday, hitting their lowest since August 2023. That brings the loss for the year so far to 22%, making them the worst performer among the major European automakers. Few automotive brands have been killed off since General Motors ditched the unprofitable Saturn and Pontiac during a U.S. government-led bankruptcy in the global financial crisis in 2008. Tavares is under pressure to revive flagging margins and sales and cut inventory in the United States as Stellantis bets on the launch of 20 new models this year which it hopes will boost profitability. Recent poor results from global carmakers have heightened worries about a weakening outlook for sales across major markets such as the U.S., whilst they also juggle an expensive transition to electric vehicles and growing competition from cheaper Chinese rivals. Japan's Nissan Motor saw first-quarter profit almost completely wiped out on Thursday and slashed its annual outlook, as deep discounting in the United States shredded its margins. Tavares said he would be working through the summer with his U.S. team on how to improve performance and cut inventory.

Jeep gives a trio of customs an encore showing at SEMA

While Jeep certainly had some new customs on display at this year's SEMA show, it wasn't afraid to recycle a few that people might have missed from earlier this year. The maker of many beloved off-roaders already displayed the Jeep Cherokee Dakar, Maximum Performance Wrangler and Wrangler Mojo at the 2014 Easter Safari, but they all made it to SEMA for an encore.
Based around the Trailhawk, the Cherokee Dakar (pictured above) imagines an even more off-road-capable version of the crossover. The concept wears a mix of Silver Steel Stain paint with Flame Red graphics and rides on 17-inch wheels wrapped in 33-inch BFGoodrich Mud Terrain tires. To back up the rugged look, the Dakar is fitted with rock rails and skid plates protecting the oil pan, front suspension, fuel tank and other underbody parts. It also sports prototype parts from Jeep Performance Parts, including a lift kit and fender flares.
The Wrangler is one of the paragons of off-roading, and as the name suggests, the Maximum Performance Wrangler concept is meant to be the ultimate example of what it can do. The custom features locking Dana 60 axles front and rear, a 4:1 Rock-Trac transfer case, prototype 4-inch lift kit and 37-inch Mud Terrain tires over beadlock wheels. To stay on the trails well into the night, a bar of LEDs is mounted above the windshield. And finally, the Mopar Blue exterior kind of makes the vehicle look like the world's toughest blueberry.
