The Jeep Grand Cherokee Trackhawk is the all-wheel-drive Hellcat you've been waiting for

If the Jeep Grand Cherokee SRT was the venerable SUV cranked to 10, the new Trackhawk goes to 11. Actually, make that 707, because the Grand Cherokee Trackhawk is a Hellcat by another name. Under the hood is the same 707-horsepower supercharged V8 from the sinister corporate cousins Charger and Challenger. The torque rating drops just a bit to 645 pound feet, versus the 650 of the Hellcats, but we don't think many people will be too upset. Especially since Jeep claims the Trackhawk is capable of a 3.5-second 0-60 mph run and a quarter-mile time of 11.6 seconds. The former is right in line with the Challenger Hellcat. View 24 Photos The Grand Cherokee Trackhawk also offers a unique difference to the Hellcats, and its not the SUV body style. The Trackhawk is all-wheel-drive. Power goes from the supercharged V8 to an 8-speed automatic and a single-speed transfer case. There's also an electronic limited slip differential at the back. Jeep beefed up the transfer case with a wider chain that features forged sprockets. The rear drive shaft and half shafts have been strengthened to handle the extra power. Power is split 40/60 front and rear in the default automatic setting, and becomes more rear biased in more aggressive driving modes. In the sportiest "Track" mode, power is split 30/70. In the least aggressive "Snow" mode, power is split 50/50. The sportier drive modes also firm up suspension and decreases shift times. This content is hosted by a third party.

The suspension lowers the SUV a full inch compared with normal Grand Cherokees. Wheels are 20 inches in diameter and 10 inches wide wrapped in 295-millimeter wide tires, either all-seasons or optional three-seasons. An optional forged set of wheels is available, too, which Jeep says will save 12 pounds of weight. The wheels are stopped by Brembo six-piston calipers and 15.75-inch rotors up front, and four-piston calipers and 13.73-inch rotors out back. Jeep says the front brakes are the largest ever fitted to one of its vehicles. Visually, you'll be hard-pressed to tell a Grand Cherokee Trackhawk from the current SRT variant. The bumpers and fender flares are roughly the same. But a tell-tale sign is the lack of fog lights.

Ram and Jeep diesel emissions allegations spur class action lawsuits

This shouldn't come as a surprise. Last week, the EPA issued a notice of violation to FCA after it determined that Jeep and Ram installed eight undisclosed auxiliary emissions control devices on diesel vehicles. Since then US law firm Heninger Garrison Davis, LLC and Canadian firm Sotos LLP have launched class action suits on behalf of owners. These latest lawsuits are unrelated to a previous class action suit brought against FCA and Cummins over NOx emissions in 2007 to 2012 Ram models. The violation notice – and the subsequent lawsuits – covers 2014 to 2016 Jeep Grand Cherokee and Ram 1500 models equipped with the 3.0-liter turbodiesel V6, a total of about 104,000 vehicles in the US. The EPA says that while the emissions control devices aren't necessarily illegal, installing them without disclosing them to the EPA is, as they produce more emissions in real world use than in testing. Skirting certification in this way might be a violation of the Clean Air Act. FCA could see fines of up to $45,000 per vehicle, depending on the outcome of the EPA investigation. FCA denies that these are cheat devices, and has proposed software updates to bring the vehicles into compliance. As for the lawsuits, Heninger Garrison Davis says that "Fiat Chrysler marketed those vehicles as environmentally friendly with enhanced fuel efficiency, better performance, and lower emissions. Although the diesel vehicles were successfully marketed as 'clean,' their environmentally-friendly representations were deceptive to consumers." The suit seeks an undisclosed amount of compensation for owners of these vehicles. In Canada, Sotos LLP is seeking $250 million in damages on behalf of owners. This suit, filed in the Ontario Superior Court of Justice, also claims deception on the part of FCA, "resulting in losses and damage" to owners. These are similar claims to group actions against Volkswagen with regard to its diesel emissions cheating scandal. While VW is fixing or buying back many of the affected vehicles, the company is defending itself against some suits on behalf of owners, saying it expects " no decline in the residual values of the affected vehicles as a result of this issue." Don't be surprised if FCA mounts a similar defense.

FCA plants skipping summer shutdown to keep up with demand

Hopefully, some FCA US factory employees don't have big plans for the usual summer shutdown, because the automaker is keeping several plants running this year. Demand is so high that the company wants to keep models rolling off the assembly lines. Four FCA US assembly plants, all the engine factories, and some locations that build transmissions are staying open throughout the summer, according to the Detroit Free Press. Usually, these sites would see a two-week shutdown for the company to retool and perform repairs. This year, factories are staying open for FCA to support its strong sales. The lines that remaining humming through the summer show an inclination toward the automaker's popular SUV's and crossovers. They include the Jefferson North Assembly Plant in Michigan that builds the Jeep Grand Cherokee and Dodge Durango; Saltillo Van Assembly in Mexico that constructs the Ram ProMaster; Toledo Assembly Complex in Ohio that produces the Cherokee and Wrangler; and Toluca Assembly in Mexico that makes the Dodge Journey and Fiat 500.
