Jeep reveals annual Moab Easter Jeep Safari concepts

Jeep has unveiled its annual spate of concepts before the Easter Jeep Safari. Those start with the Grand Cherokee Trailhawk Concept (below left), complete with the company's EcoDiesel V6 engine. Designers threw in a set of 35-inch Mickey Thompson tires wrapped around 17-inch Rubicon wheels, and a set of custom fender flares help keep all that rubber under wraps.
Meanwhile, the Wrangler Mopar Recon (below right) packs a 6.4-liter Hemi V8 good for 470 horsepower. All that grunt gets to the ground via a five-speed automatic transmission and a set of a Dana 60 axles frond and rear with 4.10 gears. The Recon also makes use of a 4.5-inch prototype long-arm kit and a set of prototype eight-lug bead lock wheels.
The Wrangler Stitch (below left) builds on the momentum of the Wrangler Pork Chop Concept. Engineers once again set out to strike as much weight as possible from the vehicle, and actually managed to trim the curb weight down to 3,000 pounds. That effort has given the machine the same power to weight ratio as the Grand Cherokee SRT8. Plenty of carbon fiber, door deletes and a chrome moly roll cage all help trim those pounds, and a set of DanyTrac Pro Rock 44 axles with 4.88 gears and ARB lockers front and rear let this machine scramble over whatever is in its path.

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.

The Jeep Wrangler is finally getting modern headlights for 2017

Some of Jeep's headlights leave a lot to be desired – namely light output. In particular, the halogen lamps on the Wrangler and Cherokee have been called out by the IIHS as among the worst on the market. Things should improve for 2017, as Jeep is addressing the sorry illumination by adding LED or HID headlight options for the Wrangler, Cherokee, and Renegade. Thank heavens (or, you know, the IIHS for upping its lighting requirements). In the Wrangler's case, the decision to develop an LED for a single model year of the JK before its replacement arrives – or two if you count the extended run of the current model alongside the new one – might seem strange, but we aren't complaining. The current headlights are one retro cue that sorely needed eradicating, plus this almost guarantees LEDs for the next-gen model. Any 2017 Wrangler can be equipped with the new LED headlights and fog lights – the LED lighting group will be optional on the Sport and Sport S, and standard on Sahara and Rubicon. The Cherokee is a slightly different story – HID headlights are currently optional on that model's Limited and High Altitude trims and standard on the range-topping Overland. Next year, the brighter, more focused lamps will be standard on everything but the base Sport model, where they'll be optional. For the wee Renegade, meanwhile, HIDs are a "late availability" option as part of the safety and security group on Latitude, Limited, and Trailhawk trim levels. If you want a 2017 Renegade Sport with the better lights, though, you're out of luck. Jeep hasn't announced pricing for its 2017 offerings, so we don't know what sort of premium the LED and HID headlamps will add. We just know that whatever the price, it will be worth it. And you can bet each unit will have some sort of Easter egg Jeep design detail on it.
