2018 Jeep Wrangler Rubicon Alaska Cannonball | Into the West

Our man Jonathon Ramsey is driving a Jeep Wrangler Rubicon on a 14-week, 14,000 mile journey across North America. Check out his first and second installments. DOVE CREEK, Colo. – Last week I hopped off the Oklahoma panhandle into Grenville, New Mexico. After a tight right-left on Grenville's Lake Road, the tarmac fell away into immense, scrub-filled valleys rimmed by rock spires and elevated mesas. Pushing into Colorado from the southeast, elevation and high-plains beauty come quickly. It's like driving through the imaginary Arcadias on bottled water labels, or one of those 5,000-piece puzzle sets that grandparents and aunts devote months and bottles of gin to. I'm shacked up in Dove Creek's surprisingly quaint Country Inn because rain. Here are some notes from the road. For lack of time and space, I only mentioned the Jeep Collection in Suwanee, Georgia in passing last week. Once more: if you're a fan of Jeeps and you get to the Atlanta metro area, I highly recommend a visit — and look at the pictures at the bottom of this article. The 2018 Wrangler Rubicon I'm driving now sports Willys icons on the gear shift lever, windshield, and wheels, and when you turn the rig on, a graphic in the dash cluster morphs from a Willys into a JL Wrangler. Jeep insists on carrying the torch of its origins, so I found it edifying to sit in all four of those origins at the Jeep Collection. I can tell you this: the Americans who fought WWII were a lot smaller than we are. What am I driving? The Monroney titles it a 2018 Jeep Wrangler Unlimited Rubicon 4X4, with a base price of $40,495. It's been plumped with these options: Leather ($1,495), Customer Preferred Package 24R (Cold Weather Group, $895), Trailer Tow HD Electrical Group ($795), LED Lighting ($895), Electronic Infotainment System Group with 8.4-inch Uconnect and Alpine Premium Audio ($1,295), Steel Bumper Group ($1,295), Trail Rail Management System ($195), All-Weather Floor Mats ($130), 8-Speed Automatic Transmission ($2,000), Premium Black Sunrider Soft Top ($595), and 17-inch black wheels with polished lips ($895). Add the $1,195 destination charge, and a customer paying MSRP would need to pony up $52,175 to take it home. Regarding my previous list of aftermarket bits, the Mopar rock rails are so well integrated that I forgot to mention them. They have come in handy. The Mopar grab handles, however, aren't so handy. The hard rubber grips hang from the roof by nylon straps, next to the front windows.

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid

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.
