NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

Inner Demon revealed: 840 hp and other jaw-dropping details

After months of teasers, rumors, cryptic messages, and veiled hints, the 2018 Dodge Challenger SRT Demon is finally here, and it's as wonderfully insane as we hoped it would be. Finally we know the facts and figures that Dodge has been hinting at for so long. 840 horsepower. 770 lb-ft of torque. 2.3 seconds to 60 mph. A quarter-mile run of 9.65 @ 140 mph. While pricing hasn't been announced, Dodge is trying to keep it under $100,000. That horsepower figure makes this the most powerful production V8 ever. With those 0-60 and quarter-mile times, it's also NHRA certified as the quickest production car ever. Someone with the means needs to line a Demon up against a Tesla Model S P100D. All that power and all of the Demon's trick launching software and hardware will throw a driver back against their seat with 1.8 Gs. Drivers will be seeing a bit of sky, as the Demon is the first production car to pull a wheelie from a dead stop. Yes, this is all totally and 100 percent street legal. View 48 Photos In order to make all this power, the red-painted supercharged 6.2-liter Hemi V8 has been significantly improved over the Hellcat. It's equipped with a larger 2.7-liter supercharger that turns the boost up to 14.5 psi, redlines at 6,500, and has what Dodge is calling SRT Power Chiller, a system that uses the air conditioning to cool the air coming in through the new Air Grabber hood scoop. In order to keep your engine running time and time again, there is an after-run cooler than cools the supercharger after the car is shut off. The pistons and connecting rods have been strengthened to deal with the higher load. In order to feed enough juice into the engine, the Demon uses dual fuel pumps. We assume that a decent EPA rating wasn't on the top of the engineer's list. Oh, and the Demon can run on 100-octane with the press of a button. With the traditional SRT black and red keys, the Demon actually has three horsepower ratings: 500 with the black key, 808 with the red key, and the full 840 with the red key and 100-octane fuel. Don't worry, even if you have the black key, the Demon will drop the 1/4 mile in 11.59 seconds, still quicker than almost anything around. Most of the rest you already know from the seemingly endless teasers. The Demon wears lightweight wheels with sticky 315/40R18 Nitto drag radials at all four corners.

The Dodge Demon's massive torque wrinkles its massive tires

Horsepower doesn't mean a damn thing if a car can't properly put the power down. That's why Dodge has fitted the upcoming Demon with some of the stickiest road-legal rubber available. Those Demon-branded Nitto NT05R drag radials skirt by regulations with just the smallest of margins, and in order to maximize the potential of the 315/40R 18 size tires Dodge increased the car's torque multiplication with a higher stall speed for the torque converter and a 3.09 rear axle. The 12.6-inch-wide tires are fitted to 18x11-inch wheels at all four corners, and they're fatter than those 305-section front tires on the Camaro Z/28 that we raved about years ago. Dodge says the combination of soft, gooey rubber and the new gear ratio gives the Demon about a 15 percent larger tire contact patch, more than twice as much grip, and roughly an 18 percent increase in both converter torque and rear-axle torque multiplication. Simply put, the Dodge Demon moves. You can see the results in the teaser video above, which is titles "Multiplication" and shows the crazy wrinkling of the sidewall that results from putting that torque to the road. We wouldn't be surprised if the inner rim of the wheel needs some grip to keep the tire seated, something Chevy had to do on the last Z/28. There is something wonderful about Dodge's approach to performance cars. While the Ford Mustang and Chevrolet Camaro have moved on from their muscle car upbringings with proper track-focused models, Dodge has stayed true to its roots by developing a machine that's sole intent is traveling a quarter-mile quicker than anything else on the road. Twisty roads may be fun, but there is something wholly and deeply satisfying about going deep into the accelerator with a comical amount of power at your disposal. We can't wait.
