Why the 2018 Jeep Grand Cherokee Trackhawk really exists

"But really, what do we do for Jeep? We listen to our customers, that's our job. We give them what they want. So the reason why is, they ask. Lots of them asked." – Darryl Smith "Why not?" It's a simple-enough explanation and one that should resonate with any car lover who views the absurd and the gloriously pointless as fundamental principles of their passion. And putting a ridiculously powerful engine into a vehicle that would normally not have one is perhaps the pinnacle of that. It's the reason that so many of us view a Mercedes-AMG E63 wagon as far cooler than an SLS AMG with roughly the same engine. With that in mind that we sat down with two of the men responsible for the 2018 Jeep Grand Cherokee Trackhawk, the latest entry into the absurd and gloriously pointless segment. We wanted to find out from Darryl Smith, director for SRT engineering, and Paul Mackiewicz, vehicle development manager, if there were actual market-based reasons for the Trackhawk's creation. Effectively, why'd they actually do it? "Why not?" Smith immediately offered during an interview at the New York Auto Show, clearly possessing a similar mindset. "But really, what do we do for Jeep? We listen to our customers, that's our job. We give them what they want. So the reason why is, they ask. Lots of them asked." View 24 Photos If "lots" of people are asking for a 707-horsepower, 645-pound-feet, off-road-capable, luxury-lined, five-person SUV, then perhaps we shouldn't be too worried about the demise of the human-driven automobile after all. "There is a very defined customer base out there that want a sport SUV," Mackiewicz said. "They want a sports car with the capabilities of having an SUV, of being able to tow, of being able to drive their sports car all year round. And that's what this car enables. It is ultimate performance, all year round, in any condition." If BMW, Mercedes-Benz, Porsche, and even Maserati can produce high-performance SUVs, doesn't it seem fitting that the father of all SUV brands should top them all under the hood? Of course, expanding the 6.2-liter Hellcat engine beyond the Challenger and Charger is clearly a smart business case in the current SUV-obsessed marketplace. FCA had a lust-worthy engine, and it had a solid performance base in the existing Grand Cherokee SRT, so it can be argued that marrying the two made sense and that it could be done with minimal fuss — even if in practical terms, it's absurd.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

Chrysler recalling 630k Jeep models worldwide

Despite its refusal to recall 2.7 million Jeep Grand Cherokee and Liberty models this week over a gas tank fire risk, Chrysler will be recalling 630,000 Jeep Compass (pictured), Patriot and Wrangler vehicles around the globe for a pair of entirely different reasons.
The affected Compass and Patriot models are all from the 2010 to 2012 model years - 254,000 in the United States, 45,400 in Canada and 109,000 elsewhere in the world. In these models, a software error may result in the late deployment of the side airbags and seatbelt tensioners. In the event of a crash, failure of these systems could result in more serious injuries for the vehicle's occupants.
Jeep's go-anywhere Wrangler also faces a separate recall due to power steering fluid lines that can possibly wear a hole in the transmission oil cooler line. According to Chrysler, the vehicles could then leak fluid, possibly damaging the transmissions. Roughly 221,100 Wrangler models are being recalled because of this issue, all of which are fitted with Jeep's 3.6-liter Pentastar V6 engine. In the US, 181,000 vehicles are affected, with an additional 18,400 in Canada and 21,700 additional units worldwide. A Chrysler spokesperson said that no crashes or injuries have been reported with either case, according to the Associated Press.
