The Dodge Demon isn't the only way to a 10-second quarter mile

The Demon's rear tires smoke, the front tires lift – and in under ten seconds (after having spent $85,000) you've covered a quarter mile. In short, we fully get the attention shown Dodge's SRT Demonstrator. With disruption the operative word of the times, it's good to see a representative of the movement coming from Detroit. The SRT Demon delivers disruption in spades. There is, however, a viable alternative – and it doesn't require getting on the list at your Dodge dealer. If you want to do 0-60 in under three seconds or the quarter mile in around 10, the folks at Honda, Kawasaki, Suzuki and Yamaha – with any of their one-liter superbikes – have you covered. The gestation of what we now know as the superbike came roughly a decade after the debut of the muscle car. It was in the early '70s, as emission and safety regulations – along with rising insurance premiums – decimated the ranks of Detroit's fastest that motorcycle makers found their magical, almost mystical momentum. Honda's CB750 four was arguably the first, followed soon by Kawasaki's Mach III and Z-1. After that, it was Katie-bar-the-door, with more horsepower offered by Japanese OEMs until, invariably, insurance premiums went higher and, during the last recession, 20-somethings couldn't get affordable loans or insurance. Today, Japan's Big Four are once again engaged in a horsepower war, fueled by the rising interest in MotoGP, along with the rising profits available when selling a $20,000 motorcycle. And if that $20,000 - $10K per wheel – seems high, simple math tells you it's less than half of what you'll spend per corner if buying Dodge's Demon. The specs tell the tale. The Demon, fattened by both its flared fenders and a platform dating from the George Bush administration, supports its 4,200+ pounds on a wheelbase of 116 inches. That's in contrast to Suzuki's GSX-R1000 – redesigned for 2017 – which puts its 443 pounds atop a wheelbase of just 56 inches. To maximize its Hemi-supplied 800+ horsepower, Dodge diverts the air conditioning from the Demon's interior to the engine, which makes racing on a summer evening (you guessed it) devilishly hot. On Suzuki's GSX-R1000 – or similarly-equipped superbikes – almost all of the air at 100+ miles per hour is directed at you. To further underscore the differences, know that the GSX-R1000 and its like-minded competition can turn a quick corner, while the Demon is hard-pressed to execute a U-turn at the end of a quarter-mile straightaway.

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.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
