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.

Chrysler, Nissan minivans earn 'dire' crash test results, says IIHS [w/video]

First introduced in 2012, the Insurance Institute for Highway Safety's small-overlap frontal crash test has become the bane of many auto engineers' existence. It's a particularly steep design challenge because it forces just 25 percent of a vehicle's front end to take the brunt of a 40-mile-per-hour impact. The newly released results of four family-minded minivans underscore just how difficult the crash test is: only one scored an Acceptable rating, and the other three did very poorly. The 2008-2015 Chrysler Town & Country and Dodge Grand Caravan, plus the 2011-2015 Nissan Quest, all received Poor ratings in the test, the IIHS' lowest possible score. The three of them showed significant crash intrusion into the driver's area. The dummy in the Nissan actually had to be cut out of the vehicle, with an IIHS spokesperson remarking, "the structure collapsed like a house of cards." In the Fiat Chrysler Automobile vans, the steering wheels moved out of the way, making the airbag less effective and letting the driver's head hit the dashboard. While it was not actually crashed, the agency is also giving the 2009-12 Volkswagen Routan a Poor score because it shares a structure with the FCA models. The newly released results of four minivans underscore just how difficult the small-offset crash test is. The refreshed 2015 Toyota Sienna (shown), conversely, earned an Acceptable rating and is also a Top Safety Pick+ because of its optional forward collision warning and automatic braking system. While the crash test dummy moved around during the impact more than the agency would have liked, sensors showed a low risk of injuries. The IIHS tested the Honda Odyssey last year, and it earned a Good overall score, the agency's best ranking. It's also a Top Safety Pick+ vehicle. The only member of the minivan segment left to test is the latest Kia Sedona, and the Institute is reportedly waiting a little longer for Kia to make changes to improve the model's performance. When reached for comment, Nissan spokesperson Steve Yaeger provided Autoblog with the following statement: "Nissan is committed to vehicle safety and believes that consumers should have information about crash protection so they can make educated buying decisions. Nissan is proud of the 2014 Quest's "good" rating in the IIHS front moderate overlap and side impact tests as well as a "good" head restraint rating.

Big rig gets blown over on Wyoming freeway, flattens police cruiser

A big rig navigating a stretch of windy Wyoming highway last week was blown over by high winds and landed on a Wyoming Highway Patrol cruiser. According to CBS News, three Wyoming Highway Patrol troopers responded to an accident along Interstate 80 near Elk Mountain on February 7. While the troopers were out of their cars assisting the crash victims, a white Volvo semi-truck lumbered up I-80 toward them. Wind gusts in that part of Wyoming were clocked in at up to 90 miles per hour on Tuesday, and one of them caught the semi as it neared the parked cruisers. Video from one of the cruiser's onboard cameras showed the big rig drift to the right as a big gust hit the trailer. Slowly, the whole rig tipped over and flattened one of the parked cruisers. The truck then slid a few feet on its side and came to a stop just aft of the cruiser. None of the troopers were injured in the incident, and two people in the truck came out of it unhurt as well. Patrol Lieutenant David Wagener told KGWN that that stretch of I-80 was closed on Tuesday to lightweight, high-profile vehicles. The truck driver was cited for the incident. High winds are no joke, and vehicles getting blown around or even clean off the road is a pretty common phenomenon. Way back in 2011, a truck got blown over in Utah. Then there was a train that got blown off a bridge in Louisiana in 2015.
