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.

This incredibly detailed toy Jeep will set you back $2,300 [w/video]

When I was a kid, I desperately wanted one of those Power Wheels Ford-badged Big Foot impersonators. They were far cooler than my lousy, plastic Big Wheel trike. This 1/8-scale electric Jeep takes the Power Wheels idea to a fanatical level. For one, the Capo Racing Jeep is as true to the real Wrangler as is possible in a 1/8-scale vehicle. Everything works, from the three-speed automatic transmission to the transfer case to the locking differentials. It uses a body-on-frame design with a real, metal multi-link suspension. In the cabin, the seats recline and the instruments light up. It has to be one of the most remarkable miniatures we've ever laid eyes on. Of course, that all comes at a price. As our chums at Jalopnik point out, for $2,300 you could pick up a full-size Wrangler. It'd be battered, sure, but it'd be something you could take on actual roads.

Watch this R/C Jeep Wrangler plow snow

There's no denying the fact that the Jeep Wrangler is one tough and rugged vehicle, and there is apparently little lost when the SUV is shrunk down for a 1:10th scale radio-controlled version. Proving that the Axial SCX10 Jeep Wrangler is not your run-of-the-mill R/C car, YouTube user Andrew Dykiel posted a pair of videos showing it clear about an inch of snow from his sidewalk and driveway during a snow storm last month.
Starting at $379.99, the Axial SCX10 costs more than most budget snowblowers, but other than paying a neighbor kid to shovel your snow, this might be the best way for a car guy to clear snow without the need for hot chocolate and ibuprofen. Better yet, it's electric, so it's zero-emission answer to snow removal! Scroll down to see how this R/C Jeep can help "shovel" snow from the warmth of your sofa. We've also thrown in a bonus video showing the mini Jeep negotiating the Rubicon Trail.
