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.

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:

Chrysler Recalling Nearly 907,000 Cars, SUVs

Nearly 907,000 Chrysler, Dodge and Jeep SUVs and cars are being recalled for alternators that can fail and heated power mirror wiring that can short and cause minor fires. The recalls, posted Thursday by U.S. safety regulators, push the total number of recalls so far this year 544, totaling a record of more than 52 million vehicles. The largest of Thursday's recalls covers nearly 470,000 Jeep Grand Cherokees, Chrysler 300s, and Dodge Chargers, Challengers and Durangos from the 2011 through 2014 model years. The alternators can fail, causing the 3.6-liter V6 engines to stall unexpectedly. The problem also can cause the electrical system to fail, as well as knock out power-assisted steering, antilock brakes and electronic stability control. It can even cause fire or smoke, according to documents Chrysler filed with the U.S. National Highway Traffic Safety Administration. NHTSA opened an investigation into the problem in July, and Chrysler began its own probe in August. The company analyzed warranty complaints and alternators that had failed. The alternator generates electricity to recharge the battery and run other devices. Chrysler investigators traced the problem to heat fatigue in an alternator diode. Chrysler said it received 322 complaints about the problem, while 55 people complained to NHTSA. The company said it knows of one crash related to the problem, but no injuries or fires. The company will replace the alternators with upgraded versions for free. Owners will be notified in November. The company says customers who see warning lights or suspect a problem should contact their dealers. The recall affects cars and SUVs sold mainly in the U.S. and Canada, but some were sold in Mexico and overseas markets. The second recall covers almost 437,000 Jeep Wranglers from 2011 through 2013. Water can find its way into the heated power mirror wiring harness and cause corrosion. That can cause a short and could cause a minor fire and smoke, as well as cause loss of function of the mirror. The problem was discovered in February after three Wranglers in Canada were damaged. Chrysler says it has 26 complaints about the problem, but it knows of no fires, crashes or injuries. Dealers will move the wiring and install a protective shield to keep water out at no cost to owners, starting in December. Most of the Wranglers are in the U.S., Canada and Mexico, but more than 78,000 were sold overseas.
