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.

Next Jeep Wrangler spotted with 8-speed and EcoDiesel

Although it may not look like it, there are big changes coming to the next-generation Wrangler. The 2018 model will use aluminum for weight savings, spawn a pickup version, and offer new engines. This latest set of spy images brings confirmation of two new powertrain items. The spy photos below show a Wrangler mule with the current interior and an eight-speed automatic shifter fitted in place of the old five-speed unit. (There's a comparison photo in the gallery.) The shifter design matches that of the refreshed Dodge Charger and Challenger; the final Jeep version is likely to differ, but this clearly indicates what kind of transmission is underneath. Chrysler builds eight-speed automatics from a ZF design and also uses some transmissions built by ZF. View 4 Photos While it's not visible in the photos, the unmistakable sound of a diesel was heard coming from this Jeep. The EcoDiesel V6 is expected to be available alongside a new turbocharged four-cylinder engine that is rumored to have the code name "Hurricane." The turbo four may completely replace the current gas V6 or be offered in addition. There's a good chance the eight-speed will also be paired with the Hurricane engine, since improved fuel economy is a goal for the new model across the board. We don't yet know whether a manual transmission will be offered again, but it's a pretty good bet for one of the gas engines since many diehard off-roaders prefer the ultimate control.

2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.
