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.

Jeep Wrangler Copper Crawler is our idea of a restrained Mopar shopping spree

According to a recent report, the Jeep Wrangler is the most popular SUV for customization, and this is backed up by the fact that the iconic off-roader was just named the Hottest 4x4-SUV at SEMA for the fourth year in a row. Looking for ways to keep its customers in-house rather than going aftermarket, Jeep and Mopar are always teaming to offer exciting new parts and pieces for the JK Wrangler.
Compared to most other Wranglers on display at SEMA - as well as other Chrysler Mopar SEMA concepts - the Jeep Wrangler Copper Crawler is surprisingly reserved, but should be no less exciting for owners to give their Wrangler a distinctive look. Starting off with an eye-catching copper paint scheme, the Jeep then goes on a Mopar catalog shopping spree with its matte black grille, black beadlock wheels, two-inch lift, Rubicon bumper (with a winch and aero end caps up front) and rocker panel and taillight guards.
Jeep also upgraded the Wrangler's transfer case for low-speed rock crawling (hence the vehicle's name) and cold-air intake for extra measure.

2015 Jeep Renegade Sport 4x4 Quick Spin [w/video]

Which is the most entertaining Jeep Renegade you can get? While one might make an argument for the Trailhawk model and its accompanying off-road hardware and consequential go-anywhere ability, that car comes with one glaring flaw – its 2.4-liter engine and nine-speed automatic transmission just aren't very entertaining. Instead, I submit the turbocharged, 1.4-liter base engine and its accompanying six-speed manual, a position that was reinforced after a recent stint behind the wheel of a very basic Sport 4x4. Not only do you get a fair amount of the Trailhawk's off-road ability – the Selec-Terrain system and a 4WD Lock mode are standard, but you'll be without the 20:1 crawl ratio and Rock off-road mode – you'll also enjoy a more dynamically interesting powertrain. Read on to see why the force-induced Renegade might just be the way to go. Driving Notes My first date with the Renegade was on the mostly empty, winding roads of northern California. There, the 1.4-liter turbocharged inline-four with 160 horsepower and 184 pound-feet of torque felt fine – with no traffic and few stoplights along the drive route, it was easy to keep the engine on boil. But this engine isn't as enjoyable in day-to-day suburban traffic. Power arrives suddenly – peak torque comes between 2,500 and 4,000 rpm – and if you don't use it, you lose it. There's not much oomph in the higher end of the rev range. With such a peaky powerband, it's easy to get caught flat-footed if you're not paying attention. Thankfully the manual transmission makes it simple to stay engaged and in the correct gear. The stick-shift is enjoyable to use, with a firm clutch that's easy to modulate and shift action that isn't sloppy or vague. The 1.4-liter engine sounds good. Turn down the stereo, stomp on the throttle, and you'll be treated to a delicious turbo whistle and a smooth exhaust note. I've said it before and I'll say it again: I want Mopar to offer the Fiat 500 Abarth's exhaust on the Renegade. It'd be fun. If you do prefer the stereo, know that the Renegade's standard four-speaker unit is weak. Base models don't offer Bluetooth or satellite radio, but you can add both of those luxuries, two extra speakers, and a five-inch touchscreen for just $695. Not a bad bargain. The Koni frequency selective dampers do an excellent job of managing both small, frequent imperfections (like freeway expansion joints), and the bigger potholes that still haven't been fixed after the havoc of Detroit's winter.
