The near-700-mile driving range of the 2016 Jeep Grand Cherokee EcoDiesel is an enticement to drive – any direction, the possibilities are endless.

We headed east, and after a lengthy drive to a remodeled farmhouse north of Oberlin, Kan., and to the 73-year-old Ford dealership building at Wray, Colo., on the double-back in direction, we had gallons of clean-diesel fuel still in the tank.

The driving range of 688 miles for the Grand Cherokee Overland EcoDiesel 4X4 is based on the SUV’s estimated highway fuel mileage of 28 and its 24.6-gallon fuel tank. We averaged 27.4 miles per gallon in 655 miles.

The fairly remarkable fuel mileage is achieved with a turbocharged 3.0-liter V-6 diesel engine, same as that used in the Ram 1500 EcoDiesel, and mated to a ZF-designed 8-speed automatic transmission from Germany. The engine, built by Italian-based VM Motori, develops strong torque of 420 lb.-ft. and provides maximum tow capacity of 7,400 pounds, equal to the Ram or Grand Cherokee with a bigger Hemi V-8 gasoline engine.

The trip to Oberlin was to visit friends Rich and Linda Gaber, associates during working years at the Denver Post/Rocky Mountain News. The Gabers, Evergreen residents, acquired the remote farmhouse several years ago to add convenience to Rich’s many pheasant-hunting trips to Kansas. We call it their “mountain cabin.”

The Grand Cherokee, finished in an all-dark granite exterior/all-black interior, was a contrast when parked last Friday afternoon outside the former Bank of Oberlin (built in 1886), and its lighter red brick. The structure now houses Jerry Anderson’s Landmark Inn.

“This is like riding in a Cadillac,” said Gaber of the Jeep, as I drove them and Jan back to the farmhouse. Jeep uses a Quadra-Lift air suspension, which can raise the Grand Cherokee 2 inches to a ground clearance of 10.8 inches, or lower it an inch for easy entry and exit.

Saturday morning, at Wray, Jan and I stopped by Bonanza Ford, my first time in the dealership since I was in high school many years ago. My dad, Dale Wells, was Ford dealer at Wray when the building was constructed in 1943.

Bob Bledsoe, owner, and Phil Riggleman, sales manager, were out of town; we got a tour of the Ford building, though, by Casey Blake, sales associate, and enjoyed visiting  with Jessi Lippert, office manager. Riggleman was in Las Vegas at the National Automobile Dealers Association annual convention, where Glenwood Springs Ford dealer Jeff Carlson was installed as national chairman for the coming year.

Parked out front, the Grand Cherokee looked at home with nearby 2016 Ford Explorers in the $50,000 price range. It reminded me of the fierce competition between Explorer and Grand Cherokee in the mid-1990s.

To drive the ecodiesel, consumers will pay a $4,500 premium. That pushed the sticker price of the fully equipped Grand Cherokee to $56,180.

Navigation and a Harman Kardon sound system with 19 speakers and subwoofer, along with voice command and Bluetooth, highlight the many amenities. Also included are leather seats with edge welting, heated and cooled in the front and heated in the back seating; heated steering wheel, active cruise, dual-zone automatic temperature control.

A driver-selectable dial on the center console offers, in addition to automatic setting for normal driving, a choice of Sand, Mud, Snow and Rock, for throttle, brake and suspension response for optimum traction. Paddle shifters on the steering wheel are tied to the transmission’s manual-mode system.

Over the first three months of this year, the Ram 1500 pickup is the runaway best-seller among light-duty diesel vehicles. Behind the Ram’s 11,999 sales through the end of March are the Chevrolet Colorado with 1,089 diesel sales, the Range Rover Sport with 988, the Jeep Grand Cherokee with 941, the full-sized Range Rover with 906, the GMC Canyon 519, the BMW X5 with 457, Mercedes GL-Class 406, BMW X3 with 382 and BMW 3-series 348. Volkswagen and Audi TDI diesel models are conspicuously absent from the leader list; sales of their TDI diesel products were halted last fall over an emissions-testing scandal.

There is no wrangling from me over the opportunity to drive a Wrangler, which I did several weeks ago.

Prominent rock rails along the sides identified it as the 2016 Jeep Wrangler Rubicon Hard Rock 4X4.

The Wranglers remind me of the tough, little CJ-5, the first Jeep I reviewed in the late 1970s.

The Hard Rock edition, besides the rock rails, includes steel bumpers front and rear, power dome hood, red tow hooks in front and rear and polished semigloss black wheels. Tires are BF Goodrich Mud-Terrain LT 255/75R17.

The two-door Wrangler’s 95.4-inch wheelbase, short overhangs and tight turn radius lend offroad opportunities in most any type terrain. Removable end wings on the front bumper increase access in rugged territory.

The Pentastar 3.6-liter V-6 engine and 5-speed automatic transmission suit the Wrangler’s capabilities just fine; not to the strength of a Hemi V-8, but more than adequate. Performance was good, on the road and offroad when the shifter was pulled into four-wheel drive. Overall fuel mileage was 17.4.

The removable hardtop, leather interior and impressive audio, along with the Hard Rock package, boosted sticker price to $43,325.
