2018 Jeep Grand Cherokee Buying Guide | Popular SUV questions and answers

The Jeep Grand Cherokee is several SUVs rolled into one. When equipped with the standard 3.6-liter V6, the Grand Cherokee is a refined and well-mannered sport-utility that delivers a comfortable ride, a handsome cabin, along with Jeep's legendary off-road prowess. At other end of the spectrum is the Trackhawk, a Grand Cherokee with the heart of a 707-horsepower muscle car. Powered by the same supercharged V8 found in the ferociously quick Dodge Challenger Hellcat, the Grand Cherokee Trackhawk is one of the fastest and wildest SUVs of all time. Between these extremes there are plenty of other options, including two somewhat less powerful (but still potent) choices of V8. An available air suspension not only helps to make the ride smoother, it can significantly raise the ride height for any rock-crawling moments you encounter. Here you'll find all the information needed to make an educated buying decision if you're considering a 2018 Jeep Grand Cherokee, including safety and reliability ratings, engine specs, horsepower, fuel economy ratings and pricing. We'll also summarize what Autoblog's professional auto reviewers think of the Jeep Grand Cherokee. Is the 2018 Jeep Grand Cherokee Safe? The Jeep Grand Cherokee scores four out of a possible five stars in the National Highway Traffic Safety Administration's overall crash-test rating system. The Grand Cherokee was tested in both rear- and all-wheel drive format. The two Grand Cherokee models tested earned four-star ratings in frontal impact tests, and five stars in NHTSA's side impact tests. The only difference between the two is regarding their resistance to rollover, with the rear-wheel drive Grand Cherokee scoring a three-star rating, versus four stars in the all-wheel drive model. The Insurance Institute for Highway Safety, which provides ratings for new vehicles based on its own comprehensive crash tests, found room for improvement when it comes to the Grand Cherokee's performance in its crash test regime. While it earned top marks in some categories – such as side impact crash tests, and front crash avoidance (when fitted with optional safety equipment) – the Grand Cherokee registered a "Marginal" and "Poor" rating for its performance in the Small Overlap Front test. This simulates a vehicle hitting a static object, such as a utility pole, with only a fraction of its front end.

In Michigan, car hackers could face life imprisonment

Car hackers may not want to mess with vehicles in and around the Motor City. A pair of Michigan lawmakers introduced legislation Thursday that would punish anyone who infiltrates a vehicle's electronic systems with penalties as harsh as life imprisonment. Senate bill 927 says that "a person shall not intentionally access or cause access to be made to an electronic system of a motor vehicle to willfully destroy, damage, impair, alter or gain unauthorized control of the motor vehicle." Offenders will be deemed guilty of a felony, and may be imprisoned for any number of years up to life in prison. The proposed legislation is one of the first attempts nationally to address the consequences for car hacking, which has become a top concern throughout the auto industry. Critics have accused executives of being slow to respond to the threats, which were first known as long as six years ago but gained attention last July when a pair of researchers remotely controlled a Jeep Cherokee. In January, the industry established an Information Sharing and Analysis Center to collectively evaluate security measures and counter breaches. But the Michigan bill isn't noteworthy only because of the life penalty prescribed; it's noteworthy for what's missing in its details. Language in the bill doesn't delineate between independent cyber-security researchers and criminals who intend to inflict harm or havoc. Under its provisions, it's possible Charlie Miller, pictured below, and Chris Valasek, the researchers who demonstrated last summer that the Cherokee could be remotely commandeered and controlled, could face life behind bars. Provisions of the legislation that prevent a person from "altering" the motor vehicle could ensnare car enthusiasts or gearheads who tinker with electronic systems to boost performance, increase fuel efficiency or add aftermarket features. In that context, Senate Bill 927 seems like the latest measure in a running feud between independent researchers, gearheads and big automakers. Car companies don't like third parties poking around their electronic systems and would prefer the researchers not reveal security weaknesses. Researchers, on the other hand, say many carmakers are either slow to fix or unwilling to repair security holes unless they're able to publish their findings.

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.
