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.

Auto critic calls out Corvette, Mustang and Cherokee faithful

Most automotive purists fear change, but not without reason. Change, after all, did kill big-block V8s, along with most station wagons and manual transmissions. But change has also brought with it far more performance, safety and fuel economy - not to mention ridding the world of shag carpet interiors, bias-ply tires and those horrible motorized seatbelts of the early '90s.
By this time next year, the Chevy Corvette, Jeep Cherokee and next-generation Ford Mustang will all be on sale and will all, in some way, have angered or offended purists. To those critics, Mark Phelan of the Detroit Free Press is preemptively telling them to stop complaining - at least until they've all been driven. From the Corvette's square taillights and the Cherokee's radical nose to whatever pony car purists will harp on the 2015 Mustang for, Phelan's column points out the positives of automotive evolution and the negatives of staying the course for too long. That's fair enough, but do you think Phelan is on point, or all wet? Head on over to the Detroit Free Press to read his words, then have your say in Comments.

2013 AEV Brute Double Cab

These are the guys who bring an M777 howitzer to a knife fight. In terms of overall rugged utility, the all-new 2013 Brute Double Cab from American Expedition Vehicles (AEV) is about as overkill as they come, and we can't seem to get enough of the beasts that this company produces. Unlike most aftermarket firms, always striving to lower cost and increase volume (but at the expense of quality), Michigan-based AEV takes pride in its OEM-quality design, engineering, manufacturing and testing. Everything is as good, or better, than the stuff from the factory, and they have been doing it this way for more than 15 years.
Launched at the recent 2012 SEMA show was the 2013 AEV Brute Double Cab. Its debut marked the company's expansion to a four-door Brute on the newer JK platform (drawing inspiration from the Land Rover Defender 130). I recently spent a few hours with the new truck in sunny Southern California, though unfortunately, due to time constraints, I was limited to pavement-only driving impressions.
