Buy this instead of a Wrangler | 2017 Jeep Grand Cherokee Trailhawk Review

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.

What's really going on with the 2014 Jeep Cherokee's transmission issues?

On September 23, Automotive News reported that Chrysler had idled the second shift workers it hired just five weeks prior at its Toledo Assembly Complex to build the 2014 Jeep Cherokee. At the time, Chrysler said it had "built the critical number of vehicles we need to stock dealerships once containment is released" and did not want "to put additional strain on our logistics partners ... upon release." That reasoning was not only unusual, it didn't seem to make sense.
It appears the center of the nine-speed issue is software, not hardware.
That same day, the Detroit News ran a piece claiming workers at the Toledo factory said the halt was due to issues with the Cherokee's transmission. It put the number of already-built Cherokees needing fixes at 1,000 and said that some of the workers not laid off had been instructed "to take the Jeep on long test-drives." That made more sense. Three days later, on September 26, Automotive News reported that the 500 workers laid off had been reinstated, with engineers "speeding repairs on the SUV's powertrain software." The AN piece didn't put a number on how many units are being fixed, but it did say that 12,000 have been built and are awaiting delivery to dealers. The best it could say about when dealers will get them, however, is that "progress on a fix is being made. It's unclear when shipments to dealers will start."

Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.
