EPA posts 2018 Jeep Wrangler Unlimited fuel economy

When Jeep loosed a trio of 2018 Wrangler photos in October, Jeep cognoscenti parried over details like radio antenna placement and painted tailgate hinges, while every other viewer merely noted, "It's still a Wrangler." Now that the Environmental Protection Agency's listed fuel economy ratings for the 2018 Wrangler Unlimited with the 3.6-liter V6, Jeep savants will again parry over details. Every other viewer will merely note, "It's still got Wrangler gas mileage." According to the EPA, the current Wrangler Unlimited with the 3.6-liter V6 and six-speed manual clocks 16 miles per gallon in the city, 21 on the highway, and 18 combined. The 2018 version with the same six-speed manual comes in at 17/23/19. Switching transmissions, the current model with the five-speed automatic hooks up 16/20/18, the 2018 model with an eight-speed automatic does 18/23/20. Those numbers might not jump off the page, yet according to the EPA's cost calculator, you'll save $250 per year on gas with the eight-speed auto 2018 Wrangler Unlimited, $150 per year with the coming six-speed manual. The eight-speed auto option also exceeds Chrysler's prediction from 2014 of a nine-percent improvement in fuel economy over the five-speed auto. Now we wait for numbers on the dark horse four-cylinder, which we'd expect to best the sixer's numbers, unless the rumors are true and the four-pot really is packing every wild horse it can handle. In that case, we'll turn to the EcoDiesel for frugal kicks. If we don't find out beforehand, we can expect those goodies and more at the LA Auto Show in December.

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.

The List: Best of proving grounds

Proving grounds are where automakers and enthusiasts alike go to push their vehicles to their mechanical limits. The Rubicon Trail, located in the Sierra Nevada, is the ultimate off-road test, while Germany's Nurburgring is a grueling 13 mile road and track course.
