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 may be testing a Hellcat 300

Another day goes by, and another mysterious, undisguised SRT prototype comes out of FCA. This time we have a Chrysler 300 SRT that looks nearly stock except for its footwear. Our spy photographer got up close and personal with this machine, and found that it has the same wheels with 315-mm tires that were on the early Dodge Demon prototypes. The only difference is the wheels on this 300 have Chrysler-branded center caps. All that extra width means these wheels stick pretty far out from the wheel wells, which would suggest that any production car running this setup would have flares to cover the wheels. Behind those wheels are four-piston Brembo calipers and slotted discs that looks similar to those on the current 300 SRT. We doubt that Chrysler is building a Demonized version of the 300, but the tires do suggest that this is a much more potent 300 than the current SRT, which was discontinued in the US in 2015 but is still sold in the Middle East and Australia. That's not all we have to go on, though, since our spy photographer says it sounded like it had Hellcat power under the hood. Equipping a 300 with a Hellcat engine would be a breeze, too, since the engine is already in the Charger, which is virtually identical mechanically. What you may be wondering is why Chrysler is adding a Hellcat version of the 300 SRT when that model hasn't been available in the US since 2015. One possible reason is that this would finally allow Aussies access to the 707-horsepower machine. Dodge is not a brand offered Down Under, so it doesn't get the Charger Hellcat, leaving the 300 as the only V8, rear-drive Mopar available. And for the Middle East, if the normal 300 SRT was selling well, it would only make sense to offer another variant. It shouldn't cost Chrysler too much to develop this model either, since the 300, mechanically, is virtually identical to the Charger.
