Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

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.

Dodge Dart pushed toward the grave with simplified lineup

FCA announced a while back that the Dodge Dart and its Chrysler 200 half-sibling are on the way out due to lack of interest. The 2016 model year will be the Dart's last, and Dodge has just reconfigured the lineup mid-year to lower (relative) pricing and streamline ordering. Streamlined is a nice way of saying there will be fewer choices, with three models (down from five) and limited customization beyond choosing the paint color. The odd thing is that the Dart continues to offer three different engines. And while the prices of the individual models have decreased, the former SE base trim is now gone. That means an early-2016 Dart was available for as little as $17,990, while the late-2016 Dart starts at $18,990. For that sum you get the new base model, the SXT Sport, which replaces the SXT and comes with the 2.0-liter Tigershark four-cylinder (160 horsepower, 148 lb-ft of torque) and a six-speed manual; a six-speed automatic is an available option. Standard equipment includes normal entry-level car stuff, black cloth upholstery, 16-inch wheels, and grille shutters that help improve fuel economy. The SXT Sport can be dressed up with one of three different appearance packages; Chrome adds bright accents to parts including the grille and door handles, Rallye has a black grille and a touring suspension, and the Blacktop package makes pretty much everything on the exterior black and includes a sport-tuned suspension. All three packages come with bigger wheels, too. From there it's on to the new Dart Turbo, for $20,490. It comes with the 1.4-liter turbo four (160 hp, 184 lb-ft of torque) and comes exclusively with a six-speed manual transmission. This is supposed to be the model for enthusiasts, which is how Dodge is selling the switch to manual-only. Ditching the disliked dual-clutch automatic that was previously offered with this engine doesn't hurt. This engine was also used in the former Aero model, as it's the most fuel-efficient in the lineup. The Turbo gets the Rallye appearance stuff and a different hood. At the top is the Dart GT Sport, starting at $21,900. It has the 184-hp, 2.4-liter Tigershark four-cylinder and a choice of six-speed manual or automatic transmission. This is the one with features, including a power driver's seat, the 8.4-inch Uconnect infotainment unit, digital reconfigurable gauges, dual-zone auto climate, keyless start, and a rearview camera. The latter-part-of-2016 Dart will be available in eight colors.
