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.

Watch this 840-hp Jeep Grand Cherokee SRT8 walk away from GT-Rs and M3s

This last-generation Jeep Grand Cherokee SRT8 does things that SUVs just shouldn't be able to do, like win drag races against tuned Nissan GT-R and BMW M3 coupes. Granted, the owner isn't coming into this fight with a stock Jeep – far from it. In addition to twin turbos whistling away, he says the engine is a 449-cubic-inch V8, which is nearly 7.4 liters of displacement. As it runs here, the driver claims that the turbos are pumping out around 14 psi of boost to give an estimated 840 horsepower. What's more, he further maintains the powertrain could reach around 1,200 hp with things fully cranked up. Even somewhat dialed back, this Jeep is ready to take on a breadth of formidable challengers, including a couple of Chevrolet Corvette models and a Lamborghini Aventador. Check out the video to see how this menacing Grand Cherokee fares in a day at the races.

Jeep's 3-row crossover SUV caught inside and out

Jeep is continuing to test its upcoming three-row full-size crossover, as evidenced by new spy photos shown above. Though the exterior doesn't reveal much new, we do get our first look at the inside of the new SUV. Unfortunately, the interior is well-camouflaged. We can tell it has the same corporate steering wheel and shifter as found on other Jeeps such as the Grand Cherokee. It also has highly-stylized gauges and needles, with an LCD display between the two main dials. The gauge cluster is interesting with a dial layout that is completely different from the two-row Grand Cherokee and the three-row Dodge Durango, indicating it doesn't borrow much on the inside from those vehicles. The tachometer is clearly visible, too, and it shows a redline of about 5,500 rpm. That redline corresponds with the turbocharged four-cylinder found in the Wrangler, Cherokee, and, in single-overhead-cam form, the Alfa Romeo Giulia and Stelvio. So it seems this big Jeep may have that four-cylinder engine, probably in the twin-cam Jeep iteration. This would also match previous reports, but we're sure if there will be other engine options. Based on leaked images of the SUV, it bears a passing resemblance to the Jeep Yuntu concept that was shown in China in April 2017. Those leaked images also reveal the name "Grand Commander." Many of the leaks and information about the big Jeep have been related to China, but with automakers such as Subaru and Volkswagen expanding into large three-row SUVs, we wouldn't be surprised if the big Jeep comes here, too. We could also see it carrying the old Grand Wagoneer name. Related Video:
