Jeep Wrangler diesel likely after 2015 model refresh

We automotive journalists aren't always the right people to ask about whether a US-spec vehicle should or should not be offered with a diesel powertrain (hint: the answer is usually "YES"). But when it comes to the iconic, off-road-ready Jeep Wrangler, we aren't the only ones who have been clamoring for an oil-burning engine behind that famous seven-slat grille. To that end, it appears there's good news on the horizon, as Jeep CEO Mike Manley recently told Ward's Auto that the "Wrangler is on the radar to get (a) diesel."
"I'm confident that the Grand Cherokee will show just how large a demand there is for diesel, and I think what that will do is reinforce the need for us to target Wrangler as a vehicle that can take a diesel," Manley told Ward's. The most rugged of Jeeps is scheduled to get an overhaul around 2015-16, and the diesel powertrain will likely be introduced around that time.
This year alone, Chrysler will be adding a diesel engine to the Grand Cherokee SUV, as well as the Ram 1500 pickup and Promaster utility van.

Five automakers now being investigated by NHTSA for airbag woes

It appears that Toyota's renotification to owners of recalled vehicles from last year is just the tip of the iceberg for what could potentially be a much larger industry-wide recall. The National Highway Traffic Safety Administration is opening a preliminary evaluation investigation into roughly 1.1 million vehicles from Chrysler, Honda, Mazda, Nissan, Toyota and parts supplier Takata regarding faulty airbag inflators in several models.
NHTSA has received six reports - three directly, two from Takata and one from Toyota - of vehicles with ruptured airbag inflators from 2002-2006, which resulted in three injuries. So far, all six incidents have occurred in high humidity areas like Florida and Puerto Rico. According to Toyota's latest recall announcement, the inflators may have an improper propellant that could cause it to rupture in a crash and the bag to deploy abnormally.
This new investigation follows a previous recall from April 2013 of about 3.4 million vehicles worldwide for the airbag inflators from Takata. As Autoblog reported, Toyota jumpstarted the new situation when it found that the original list of serial numbers for the faulty part was incomplete and discovered more cars in need of replacement. Honda and Nissan told us that they were investigating whether further models would need called in again as well. Mazda told Autoblog: "Regarding the current Takata situation, we're working closely with NHTSA and investigating the situation, but nothing else to report at this time." Chrysler Group responded to us with the statement: "Chrysler Group engineers are conducting the appropriate analysis. The Company will cooperate fully with the National Highway Traffic Administration."

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
