Next-gen Jeep Wrangler to get 8-speed automatic and 3.0-liter EcoDiesel

Following up on previous reports, an anonymous source within FCA has confirmed to Autoblog that the next-generation Jeep Wrangler will come to market with both a 3.0-liter, EcoDiesel V6 and ZF's critically acclaimed eight-speed automatic transmission. While this pairing makes a lot of sense (we'll explain why in a minute), until now, we only had limited reports that either item would arrive in the next-generation Wrangler. This is the first time we've heard that the eight-speed automatic and the diesel would be paired together. That said, we shouldn't be surprised by this news. FCA currently sells the Jeep Grand Cherokee and Ram 1500 with the diesel/eight-speed gearbox combo, making its inclusion in the next-gen Wrangler far from an Apollo 11-caliber feat of engineering. Naturally, we reached out to Jeep for an official comment. Spokesperson Gabrielle Schulte gave us the expected response to this kind of inquiry, telling Autoblog that FCA does not comment on future product. Jeep has flirted with the idea of a diesel Wrangler for some time, with CEO Mike Manley telling Ward's Auto just over two years ago that a Wrangler diesel was "on the radar," although at that time, we weren't certain whether it'd be the 3.0-liter EcoDiesel showing up in the rough-and-tumble off-roader. As for the eight-speed, SEC filings back in November revealed that it'd be coming to the Wrangler in 2018. Our source could not confirm which model year the 8AT/diesel would arrive in.

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.

2017 Jeep Grand Cherokee Trailhawk Quick Spin

Jeep won't come out and say it, but the 2017 Grand Cherokee Trailhawk exists to bloody the nose of the Toyota 4Runner TRD Pro. America's off-road brand hasn't built a wheeling-specific version of its Grand Cherokee flagship in years, and the last GC Trailhawk was mostly stickers and tires. It was time for a true trail-spec Grand Cherokee again. We took a quick spin (two of them, actually) in the latest Trailhawk model, which joins Renegades and Cherokees with the same badge and off-road bent for 2017. Our time was limited, and so were our initial findings. After driving on and off pavement at Fiat Chrysler's proving grounds in Chelsea, Michigan, we can tell you that on the road, this Grand Cherokee has the same refined driving dynamics as any other. As for off-roading, the capability is still somewhat of an open question. Driving Notes The suspension and off-road system tuning are what really set the Trailhawk apart from other Grand Cherokees. Jeep tweaked the four-corner Quadra-Lift air suspension to improve articulation and suspension travel, while retaining the 10.8 inches of ground clearance of lesser Quadra-Lift Grand Cherokees. Paired with the standard Quadra-Drive II four-wheel-drive system, rear electronic limited-slip diff, and 20-inch Goodyear Adventure off-road tires, the Trailhawk is not short on capability (at least on paper). Unfortunately, paper is almost where this stops. The Trailhawks we drove were pre-production models with unfinished software calibrations. The throttle on the 3.6-liter V6 Trailhawk we took on the off-road course was super touchy and hard to modulate, regardless of which Selec-Terrain off-road mode was selected. Without a reliable throttle, we were bounding over obstacles instead of negotiating them patiently. This was back in June, and Jeep's PR reps assured us at the time that the engineers knew about the oversensitive throttle and have since confirmed that the issue has been fixed for production models, which are rolling off the line in Detroit now. We're planning to get into one of those vehicles as soon as one becomes available for a full review. Like the standard model, the Trailhawk's air suspension offers more comfort than the double-wishbone front and four-link rear suspension on the 4Runner.
