The 2018 Dodge Demon sounds like nothing else on the road

The Dodge Demon seems to have a torque problem, if making too much to easily contain can be considered a problem. In order to keep all that twist under control, the Demon has a new torque reserve launch system that works all sorts of engineering black magic to build boost without overloading the rear tires and brakes. That system, combined with the sticky Nittos and the fancy new suspension, should lead to some pretty spectacular 60-foot and 1/4-mile times. The way the system works is relatively straightforward. A bypass valve on the supercharger closes, "prefilling" the blower. In order to balance revs and torque, the computer can adjust fuel flow and spark on individual cylinders. The torque reserve kicks in when Launch Mode is initiated and the engine is turning at least 1,000 rpm. The goal is to reach peak boost quicker while efficiently putting down power. The side effect is a distinct exhaust note, which Dodge admits may make it seem like the Demon is broken. That seems to be the root of the "If you know, you know" tagline that the automaker has been using since the first teaser. Those interested can even download a ringtone, which might make it seem like you have a blown-out speaker on your phone. You can get a brief taste in the latest teaser video. In addition to the new info on the Launch Mode, Dodge released a couple of new teaser images. We briefly glimpsed one of these last week. It's a shot of the Demon's performance pages. The number 757 has appeared before, and all the talk of torque leads us to conclude that this is the Demon's torque output. The number 815 was seen in a separate teaser (shown below), which we feel may be the horsepower rating. If those numbers are correct, that would mean an increase of 108 horsepower and 107 lb-ft of torque, totally reasonable numbers given all the Demon's modifications. The license plate photo is another equation or code. This one, 3.9+221=405, is just as cryptic as the others. Look for more news and hints at ifyouknowyouknow.com in the weeks leading to the Demon's reveal.

NHTSA is investigating FCA shifters for roll-away accidents again, this time the rotary units

It seems FCA's shifter troubles aren't over yet. Now, just a few months after issuing a recall to resolve user-related issues with its monostable shifters, the company is again under investigation by NHTSA. The issue is related to the potential for cars to roll away when the rotary-style shifter is not properly placed in park. Two FCA models are the subject of this investigation: the 2013–2016 Ram 1500 and the 2014–2016 Dodge Durango. NHTSA estimates about 1,000,000 vehicles would be affected if a recall is issued. The investigation was started following 43 complaints of vehicles rolling away while supposedly being in "park." Among the complaints were reports of 25 crashes and 9 injuries. NHTSA does point out that in every incident, the parking brake was not engaged. A representative from FCA also gave us an official statement regarding the investigation: "FCA US is cooperating fully with NHTSA's investigation, the scope of which is limited. Other vehicles equipped with rotary shifters are not included. In accordance with prudent practice, the Company joins NHTSA in urging all drivers to use their vehicles' parking brakes."

One of the key differences, as the representative told us, is that these vehicles have electronic parking brakes that automatically engage if the driver does not select park and then opens the door with the seatbelt unbuckled. The Ram 1500 and Durango feature mechanical, manually operated parking brakes and therefore cannot activate the brake automatically. Because this is currently an investigation, an exact cause for the incidents has yet to be determined, and none of the vehicles have been recalled. It's possible there could be a mechanical defect. However, the issue could be a confusing interface causing user error, as was the case with FCA's monostable shifters, where drivers think they've put the car in park but actually haven't. Something that indicates it could be a case of confused users is that NHTSA also opened an investigation into 2012–2014 Jaguar XF and Land Rover Range Rover Evoques for similar issues. Both vehicles use a rotary shifter and have had roll-away complaints levied as well. Even if it is a case of user error, FCA and Jaguar Land Rover may still have to recall their vehicles.

Hellcat no help to Fiat-Chrysler's bottom-of-the-pile mpg average

What, you expected the "fastest muscle car ever" to help fleetwide fuel economy? Nope, don't think that's going to happen. That means Fiat Chrysler will likely to continue to languish at the bottom of the heap when it comes to fleetwide fuel economy among the largest automakers serving the US, especially as the automaker starts to sell its Dodge Challenger SRT Hellcat. A few hundred Fiat 500E electric vehicles aren't going to turn the trend around. See, Chrysler has once again finished at the bottom of the list when it came to fleetwide fuel economy among automakers for 2014 model-year vehicles, according to a preliminary study by the US Environmental Protection Agency. Chrysler and Fiat had an average of 21.1 miles per gallon. That substantially lagged the overall 24.2 mpg average, but it was an increase from the company's 20.9 mpg average last year and the 20.1 mpg average two years prior. For 2014, General Motors had the second-worst fleetwide fuel economy at an even 22 mpg. Fiat Chrysler does say it's working on improving its fuel economy, according to Automotive News. The company plans on making its inline-four-cylinder and V6 engines smaller, and will sell more vehicles with eight- and nine-speed transmissions. Heck, there's even a plug-in hybrid version of the Chrysler Town & Country minivan in the works for late 2015, and the company can tout fuel-efficiency gains with the Chrysler 200 and Jeep Cherokee. We would be remiss if we didn't note that, compared to its muscle-car forefathers, the Hellcat actually performs pretty well at the pump. Last month, word got out that the 2015 Challenger Hellcat, equipped either with a six-speed manual or an eight-speed automatic transmission, got a combined fuel economy of 16 mpg. Heck, the automatic-tranny version got 22 mpg on the highway. And that's for a car with 707 horsepower and a 10-second quarter-mile time. Still, with the pedal floored, the car can burn a gallon and a half of fuel per minute. Ouch.
