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.

Chrysler recalling 278,222 trucks and SUVs over bad rear axles

Chrysler has issued a recall of 278,222 light trucks and sport utility vehicles here in the United States. The reason: bad rear axles. Specifically, according to the National Highway Traffic Safety Administration, the rear axle pinion nut may lack a necessary adhesive patch, which could cause the nut to loosen. If this happens, the axle can lock up, which could cause all sorts of havoc on the road.
This is an expansion of the rear axle recall announced in October of last year, where 44,300 Ram 1500 and Dodge Dakota models were being called in. At that time, 12 accidents had been reported due to the faulty axle pinion nut.
Affected vehicles include Ram 1500 trucks from the 2009 to 2012 model years, Dodge Dakota models from the 2009 to 2011 model years, and both the Chrysler Aspen and Dodge Durango SUV twins, both from the 2009 model year only.

Chrysler may be testing a Hellcat 300

Another day goes by, and another mysterious, undisguised SRT prototype comes out of FCA. This time we have a Chrysler 300 SRT that looks nearly stock except for its footwear. Our spy photographer got up close and personal with this machine, and found that it has the same wheels with 315-mm tires that were on the early Dodge Demon prototypes. The only difference is the wheels on this 300 have Chrysler-branded center caps. All that extra width means these wheels stick pretty far out from the wheel wells, which would suggest that any production car running this setup would have flares to cover the wheels. Behind those wheels are four-piston Brembo calipers and slotted discs that looks similar to those on the current 300 SRT. We doubt that Chrysler is building a Demonized version of the 300, but the tires do suggest that this is a much more potent 300 than the current SRT, which was discontinued in the US in 2015 but is still sold in the Middle East and Australia. That's not all we have to go on, though, since our spy photographer says it sounded like it had Hellcat power under the hood. Equipping a 300 with a Hellcat engine would be a breeze, too, since the engine is already in the Charger, which is virtually identical mechanically. What you may be wondering is why Chrysler is adding a Hellcat version of the 300 SRT when that model hasn't been available in the US since 2015. One possible reason is that this would finally allow Aussies access to the 707-horsepower machine. Dodge is not a brand offered Down Under, so it doesn't get the Charger Hellcat, leaving the 300 as the only V8, rear-drive Mopar available. And for the Middle East, if the normal 300 SRT was selling well, it would only make sense to offer another variant. It shouldn't cost Chrysler too much to develop this model either, since the 300, mechanically, is virtually identical to the Charger.
