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.

Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.
