Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.

The Dodge Demon's massive drag tires are just barely street legal

Despite the gaffe that was the Vin Dieselgate leak (no, not that one), Dodge and SRT are soldiering on with the twelve-part Dodge Demon rollout in the lead up to the car's reveal at the New York Auto Show. The Vin Diesel video showed what is almost assuredly the car's front, but now we get an official view of the Demon's rear in this week's video, "Wide Body." Along with the new view, Dodge shows off a cryptic license plate (Michigan #2576@35) and details on the Demon's tantalizing wheel and tire combo. That wheel and tire combo, meant to fill out the Demon's new wide wheel arches, is frankly impressive. Lightweight 18- by 11-inch wheels are wrapped in special Demon branded Nitto NT05R tires measuring an astounding 315/40R18 at all four corners. Not only does that trump the old Camaro Z/28's 305 section tires, it makes the Demon the first production car to come equipped from the factory with drag radials, claims Dodge. Presumably, the goal with the Demon is to provide enough power and grip to rotate the Earth underneath the car rather than propelling the car itself down a dragstrip. Beyond that, few other details were revealed. Dodge provided some vague information about how the "wide-body is laser clearanced, and the entire chassis is e-coated for durability before final assembly," but doesn't actually explain what that really means. We do know now that the flared fenders add 3.5 inches to the Demon's overall width. Overall, the car looks mean and purposeful, especially wrapped in just barely street-legal rubber. Follow along at www.ifyouknowyouknow.com and see if you can find and decipher all the hints. Related Video: Design/Style New York Auto Show Dodge Coupe Performance tires dodge demon dodge hellcat

Dodge Durango could get eTorque mild hybrid system in 2020

The 2020 Dodge Durango appears slated to get a mild-hybrid powertrain option. That's the word from moparinsiders.com, which unearthed the news from documents relating to contract negotiation between the FCA and the UAW. Although the documents give no further details, it's a pretty safe bet that we're talking about Chrysler's eTorque mild-hybrid system, which was introduced on the Ram 1500 pickup and has since been extended to the Jeep Wrangler. Currently, the Wrangler offers the eTorque system on the 2.0-liter inline-four and the 3.6-liter Pentastar V6, both on the Sahara model only, while the Ram 1500 makes the mild-hybrid system standard with the 3.6-liter V6 and an option with the 5.7-liter Hemi V8. The V6 eTorque powertrain makes 305 horsepower and 269 pound-feet of torque (Ram) or 285 horsepower and 260 pound-feet (Wrangler). The Wrangler's four-cylinder eTorque is good for 270 horses and 295 lb-ft. The V8 version in the Ram is good for 395 horsepower and 410 lb-ft of torque. In all cases, the eTorque system does not increase peak output over the standard version of the gasoline engine. The mild-hybrid system does provide a minor fuel-economy boost. In the Wrangler, the 3.6-liter with eTorque has EPA city estimates that are 1 mpg better than without the system. On the Ram's V8, eTorque adds 2 mpg city and 1 mpg highway. (The 2.0-liter sees no improvement in its EPA ratings.) It's not known whether the Durango will add eTorque to its V6, or V8, or both. Either engine could do with a fuel-economy boost, as the V6 is EPA rated at 19/26 mpg city/highway (RWD) and 18/25 mpg (AWD), while the V8 version has estimates of 14/22 mpg. Related Video:
