Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.

2014 Jeep Cherokee musters 22 MPG city, 31 highway

Production and media drive delays included, there has been no lack of press surrounding the 2014 Jeep Cherokee. With the most recent delay reportedly due to powertrain calibrations, we've been waiting to see how the Cherokee's fuel economy looks against the highly competitive compact CUV segment. Thanks to the EPA, we now know the fuel economy figures for the newest member of the Jeep family.
Arguably, the Cherokee has the most modern powertrain in its class with an updated base engine, all-new V6 and all-new nine-speed automatic transmission, but its fuel economy figures are simply on par for the segment. Still nothing to scoff at, though. According to fueleconomy.gov, front-wheel-drive Cherokee models with the base four-cylinder mill will top out the lineup with 22 miles per gallon in the city and 31 mpg on the highway; opting for four-wheel drive with this engine drops the figures to 21 city and 28 highway. Get even crazier with the option list, and the new 3.2-liter Pentastar V6 will get you 19 mpg city and 28 mpg highway in two-wheel-drive form or 19 city and 27 highway for 4WD.
If you're wondering how that stacks up among compact CUVs, head on over to Automobile Magazine for a full fuel economy breakdown for the segment. The controversially styled crossover hits dealers this month, and we'll be driving it in just a couple of weeks.

AEV Jeep Wrangler Unlimited Rubicon

After their rented 2007 Hummer H3 failed them during the brutal Rallye Aicha des Gazelles in Morocco, Amy Lerner and her sister Tricia Reina were on a quest to find the most capable production off-roader for their next competition - they chose a 2012 Jeep Wrangler Unlimited Rubicon. Their next mission was to find a company with the competence to configure it to win. After poring over Internet forums and perusing countless magazines for an outfitter who could meet their demanding requirements, they sent their bright orange JK ("Crush" is the official color) to American Expedition Vehicles (AEV) for some modifications.
The Michigan-based team at AEV kept the Jeep's 3.6-liter V6 and automatic transmission stock, but replaced the hood with a tall AEV Heat Reduction Hood and added an AEV Snorkel Kit for water crossings (it serves double-duty as its raised height helps to keep the air intake out of the kicked-up dust on the trail). Front and rear off-road bumpers were bolted in place, and AEV skid plates were added to provide additional undercarriage protection. A pair of IPF-900 off-road lights improve visibility, while a 10.2-gallon AEV Fuel Caddy (located behind the exterior spare) added some range. The suspension was upgraded with a 3.5-inch lift kit with Bilstein remote reservoir shocks, and 35-inch Falken Wildpeak A/T tires (LT285/70R17) were mounted at all four corners on AEV's beadlock wheels.
