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.

Dodge Durango SRT Pursuit packs the 797-horsepower Hellcat Redeye engine

When the Jeep Grand Cherokee SRT Trackhawk launched we were stunned that it featured both the 707-horsepower Hellcat engine and all-wheel drive. But SRT has one-upped itself with a custom Durango for the One Lap of America motorsports event. It's called the Dodge Durango SRT Pursuit — nicknamed "Speed Trap" — and it has the 797-horsepower Hellcat Redeye engine, and it still has all-wheel drive! Besides the 90-horsepower advantage over the stock Trackhawk, the Durango SRT Pursuit race SUV gets improved handling via concept lowering springs and 11-inch wide wheels with 305-mm wide tires that are shared with the Challenger Hellcat Widebody. It has improved stopping ability from 15.75-inch brake rotors up front with 6-piston calipers, and 13.78-inch rotors with four-piston calipers. This is the same kind of setup as the Trackhawk uses. Oddly enough, Dodge left the factory heated and cooled front seats, but removed the two rear rows of seats for weight savings. The Durango also gets a roll cage and racing harness. The finishing touches include a cat-back exhaust and the low-profile police light bar and paint scheme. Now before you ask, there don't appear to be plans to put a Redeye-powered Durango into production. With that being said, the company clearly has the capability to mate that engine to an all-wheel-drive system, and it would be hard to imagine the company not capitalizing on that. Even if the powertrain didn't make it to a Durango, it would seem like a great complement to the existing Grand Cherokee Trackhawk, or even an updated version of it. Hint, hint, wink, wink, FCA.

How fracking is causing Chrysler minivans to sit on Detroit's riverfront

It's fascinating the way that one change to a complex system can have all sorts of unintended consequences. For instance, there are hundreds of new Chrysler Town and County and Dodge Grand Caravan minivans built in Windsor, Ontario, sitting in lots on the Detroit waterfront because of the energy boom in the Bakken oil field in the northern US and parts of Canada.
The huge amount of crude oil coming from these sites mostly use freight trains for transport, and that supply boom has resulted in a shortage of railcars to carry other goods. According to The Windsor Star, North American crude oil transport by train has gone from 9,500 carloads in 2008 to 434,032 carloads in 2013. Making matters worse, some North American rail infrastructure is still damaged because of this year's harsh winter, and that's slowing things down even further.
Chrysler admits to The Star that it has had some delivery delays due to the freight train shortage. In the meantime, it's using more trucks to deliver its vehicles. Trucking is a far less economical solution, partially because a train can carry so many more units at one time, but alternatives are slim. The Windsor plant alone has a deal for 33 trucks to distribute the minivans around Canada and the Midwestern US.
