2014 Jeep Grand Cherokee

Jeep appears to have nailed it this time. After two decades of assembling its Grand Cherokee sport utility vehicle, the American automaker has finally delivered a world-class off-roader capable of taking on everything in its segment - and more - with a high likelihood of coming out on top.
And if you drove last year's model, it's time to climb behind the wheel again as Jeep has significantly updated the SUV for 2014 with a bold new exterior appearance, an upgraded interior with enhanced electronics and a new transmission that completely transforms the way it drives.
We recently spent a full week with a dark blue 2014 Jeep Grand Cherokee Overland 4x4, a well-optioned model fitted with the standard gasoline-fed V6. While it didn't have the punch of the range-topping V8-powered SRT8, or the fuel-sipping economy of its new EcoDiesel sibling, the high-volume variant left us quite impressed.

500+ hp Stellantis 'Hurricane' I6 previews a world without Hemis

After years of rumored development, Stellantis has revealed its new six-cylinder engine family. The 3.0-liter, twin-turbocharged "Hurricane" I6 will offer V8 power, forced induction torque and six-cylinder efficiency in a package designed to fit into any of the company's North American rear-wheel-drive platforms.  What is "V8 power," exactly? Well, in standard output guise, the new I6 cranks out more than 400 horsepower (the specific figure will vary by application) and 450 pound-feet of torque, while the high-output variant is good for more than 500 horses and 475 lb-ft. The final figures will be dependent on the application. We'll save you a little legwork: In current Ram, Jeep and Dodge products, the 5.7-liter Hemi tops out at about 395 hp and 410 lb-ft, give or take, and the 6.4-liter around 485 hp and 475 lb-ft.    This is a clean-sheet design that is only related to the company's turbocharged four-cylinder by some common measurements. The I6 is exclusively direct-injection (no hybrid/port-injection here) and the two I6 variants share 96 common parts, including the block and oil pan design. The differences are found in their internals, intake plumbing, valvetrain components and the turbochargers themselves. Stellantis is not yet ready to share specs or supplier info for the turbos but says announcements will come from its partners soon.  The standard-output I6 has a compression ratio of 10.4:1 and revs to 5,800 rpm. It will run on regular fuel, albeit with reduced performance; 91 octane is recommended for maximum output. The high-output variant has a compression ratio of 9.4:1 and will rev to 6,100 rpm. That one will require premium. The new I6's advantages go beyond basic power output. Every Hemi family engine currently in production is based on an iron block design, so they're heavy. The aluminum-block I6 shaves weight off the total engine package, even if some of that gets added back thanks to the turbos and their associated plumbing. The standard-output I6 weighs 430 pounds, Stellantis engineers told us; the high-output adds just another 11. Fully dressed 5.7-liter V8s are in the 550-560-pound ballpark, and 6.4-liters close in on 600 pounds.  You may be wondering, "Why a clean-sheet gasoline engine now, when the industry is moving toward battery-electrics?" A valid inquiry, and one Stellantis was prepared to address. While the company will be pivoting to electrification over the next decade, it won't be instantaneous.

Jeep Grand Commander three-row crossover SUV revealed in Beijing

Jeep has finally revealed its first three-row SUV since the Commander, and the new one is called, as we expected, Grand Commander. And it looks just like we expected from leaked images and patent drawings. It pulls a bit of inspiration from the Jeep Yuntu concept, but it generally looks like a much bigger, stretched-out Compass. We do see a bit of Renegade inspiration in the D-pillar, though. Interestingly, the Grand Commander isn't really bigger than our Grand Cherokee. The Grand Commander is just under 192 inches long, which is only 2 inches longer than the Grand Cherokee. But the Grand Commander's wheelbase is four inches shorter. It's also about two inches narrower than the Grand Cherokee. This is all interesting considering the Grand Commander's greater passenger capacity. Also interesting is the Grand Commander's powertrain. It's only available with a turbocharged 2.0-liter four-cylinder, likely lifted from the Jeep Cherokee and Wrangler. If so, it's been detuned, and it now makes just 231 horsepower and 258 pound-feet of torque as opposed to the 270 horsepower and 295 pound-feet in the other Jeeps. The Grand Commander's four-cylinder is also paired to a nine-speed automatic, and it can be had with either two-wheel or four-wheel drive. The question of course is, will the Grand Commander come to America? It would fill a gap in the Jeep lineup, since the brand has no three-row vehicles. There have been many rumors of a three-row Jeep, possibly called Grand Wagoneer, as well as Grand Commander prototypes running around the U.S. But the size of the Grand Commander has us questioning whether it would be brought here, or if Jeep would develop a larger three-row, maybe based on Durango, for our market.
