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.

Ram 1500 wins Consumer Reports fullsize truck test

Vehicles that perform well in road tests by some of the most popular automotive publications, such as Car and Driver, Motor Trend and Automobile, don't always score well in in Consumer Reports' more regimented, practical test procedures, so the Ram 1500's climb to the top of CR's scoreboard is a boon for the well-received pickup truck, which CR also put on its "recommended" list.
To start off with, the freshened 2013 Ram 1500 has a lighter, stiffer chassis than before, and the four-wheel-drive Crew Cab that CR bought and tested performed flawlessly and achieved class-leading fuel economy (15 miles per gallon) with the 5.7-liter Hemi V8 - the most popular engine choice for the 1500 - and the new eight-speed automatic transmission. The unique-in-its-class rear coil spring setup endowed the truck with "one of the best rides of any pickup," CR reports. That helped it earn its class-leading road-test score of 78, well ahead of the nearest competition still in production, the Toyota Tundra (69) and the Ford F-150 (68). It's worth noting, however, that the Chevrolet Avalanche outscores the 1500 by two points (80), but production of that vehicle ends after the current 2013 model year.
About the only things the publication could find wrong with the truck were a heavy tailgate and a high step up into the cabin. Get ready for the next round later this summer when CR is finished testing the 2014 Chevrolet Silverado, which is doing well so far in the publication's tests.

Ram introduces 33-mpg Tradesman HFE EcoDiesel

Ram announced Tuesday that its 2021 1500 Tradesman HFE EcoDiesel trim goes toe-to-toe (tow-to-tow?) with the segment's most efficient diesels, offering 23 mpg in the city, 33 mpg on the highway and 26 mpg combined. That's good enough for a first-place tie in the segment, as those numbers now match those of Chevy's Silverado 1500 with the 3.0-liter Duramax oil-burner.  "Ram is committed to innovation and powertrain leadership, and as the no-compromise benchmark for efficiency and performance, we continue to listen to customer input by offering unsurpassed fuel economy," said Ram boss Mike Koval Jr. "The Ram 1500 is America’s most powerful half-ton diesel pickup with 480 lb.-ft. of torque and the most capable light-duty diesel with towing capability up to 12,560 pounds, and delivers up to 1,000 miles of range on a single tank of fuel." From a glance at Ram's specs table, it appears the HFE EcoDiesel configuration (based on a Crew Cab Tradesman with the 5-foot 7-inch bed) is good for 8,210 pounds of trailering and 1,780 lbs of payload. It's worth noting that the Chevy matches the HFE's fuel economy while also providing more towing capability. You can trade the HFE's small fuel economy gain for a bit more towing capability by going to a 3.92:1 rear axle. That will buy you another 1,700 lbs of towing. Even more towing capacity (specifically, the 12,560 lbs maximum quoted above) comes with the Ram 1500 Quad Cab EcoDiesel.  Standard equipment for the HFE includes 20-inch aluminum wheels, a black grille and bumper cover, a tonneau cover, step rails and some perfectly decent cloth seats. The HFE EcoDiesel is available in one of a whopping two finishes: black or white. Exciting. Ram says the HFE will start to appear on dealer lots in the second quarter, and the truck will start at $43,935 (including $1,695 for destination). Related Video:
