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.

Lexus tops JD Power Vehicle Dependability Study again, Buick bests Toyota

It shouldn't surprise anyone, but Lexus has once again taken the top spot in JD Power's Vehicle Dependability Study. That'd be the Japanese luxury brand's fourth straight year at the top of table. The big news, though, is the rise of Buick. General Motor's near-premium brand beat out Toyota to take second place, with 110 problems per 100 vehicles compared to Toyota's 111 problems. Lexus owners only reported 89 problems per 100 vehicles. Besides Buick's three-position jump, Scion enjoyed a major improvement, jumping 13 positions from 2014. Ram and Mitsubishi made big gains, as well, moving up 11 and 10 positions, respectively. In terms of individual segments, GM and Toyota both excelled, taking home seven segment awards each. The study wasn't good news for all involved, though. A number of popular automakers finished below the industry average of 147 problems per 100 vehicles, including Subaru, (157PP100), Volkswagen (165PP100), Ford/Hyundai (188PP100 each) and Mini (193PP100). The biggest losers (by a tremendous margin, we might add) were Land Rover and Fiat, recording 258 and 273 problems per 100 vehicles. The next closest brand was Jeep, with 197PP100. While the Vehicle Dependability Study uses the same measurement system as the Initial Quality Survey, the two metrics analyze very different things. The VDS looks at problems experienced by original owners of model year 2012 vehicles over the past 12 months, while the oft-quoted IQS focuses on problems in the first 90 days of new-vehicle ownership. Like the IQS, though, the VDS has a rather broad definition of what a problem is. Because of that, a low score from JD Power is no guarantee of extreme unreliability, so much as just poor design. In this most recent study, the two most reported problems focused on Bluetooth connectivity and the voice-command systems. The former leaves plenty of room for user error due to poor design (particularly true of the Bluetooth systems on the low-scoring Fords, Volkswagens and Subarus), while the second is something JD Power has already confirmed as being universally terrible. That makes means that while these studies are important, they shouldn't be taken as gospel when it comes to automotive reliability.

Stellantis will build four electric vehicles in Italy, say union reps

MILAN — Stellantis will produce four medium-segment electric vehicles, of different brands, at its Melfi plant in southern Italy from 2024, the UILM union said on Tuesday. Since Stellantis was formed at the beginning of this year through the merger of Fiat Chrysler and France's PSA, production in Italy has been under scrutiny for costing more than elsewhere in Europe. "Stellantis announced that Melfi would be the first plant in Italy to get new models, based on post-2022 business plan," UILM said in a statement after workers' representatives met with the carmaker at Italy's industry ministry in Rome. Future production at Melfi will be based on a single enhanced production line that will merge the two existing ones, the union said, adding the restructuring will leave production capacity at the site unchanged at around 400,000 units. UILM's head, Rocco Palombella, said unions had not received all the answers they wanted as Stellantis was still working on its new business plan. "But the positive element is that the company has not absolutely called for structural redundancies," he said after the meeting. Stellantis Chief Executive Carlos Tavares has said the group would present its business plan late this year or in early 2022. Stellantis, the world's fourth-largest carmaker, gave no details about what was discussed at the meeting. In an earlier statement the company said it was working "with determination and speed" to support the energy transition of all its Italian sites. Italy's Industry minister, Giancarlo Giorgetti, however, said in a separate statement after the meeting that Stellantis had yet to decide where it would build its third electric battery plant in Europe. Stellantis, which already has two battery factory projects in France and Germany, has said adding gigafactories in Europe and the United States would be decided this year. The company is holding talks on this with Rome, as Italy is one of its main production hubs in Europe. Related video: Green Plants/Manufacturing Alfa Romeo Fiat Jeep Citroen Opel Peugeot Stellantis
