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.

Sunday Drive: Trucks and SUVs of all shapes and sizes

The American automotive marketplace is dominated by trucks and SUVs, and so was the last week of coverage on Autoblog. By far, the most popular story of the week was our First Drive of the 2018 Lincoln Navigator. It may look like an old-school lumberer, but in reality Lincoln's flagship is a thoroughly modern, turbocharged-V6-powered, three-row, luxury people mover. The Jeep Wrangler is the world's most recognizable vehicle. So it's no surprise that the next version looks a whole heck of a lot like the last one, and the one before. It's all in the details, which is why we were so excited when Jeep decided to unleash a trio of images showing both two- and four-door Wranglers for us to dissect ahead of the SUV's official debut at the L.A. Auto Show later this year. Past that, spy photos of the next Chevy Silverado and Ram 1500 were predictably popular. See both of those below, and the cap it all off, check out the entire week's worth of SEMA coverage – including the bonkers Hennessey VelociRaptor 6x6 – in our mega image gallery at the bottom of this post. Enjoy! As always, tune in to Autoblog next week for a front-row seat to all the happenings worth following in the automotive industry. 2018 Lincoln Navigator First Drive | From black sheep to flagship 2018 Jeep Wrangler revealed: First photos released before L.A.

Texas student drives Barbie Jeep to school after DWI

A Texas college student who lost her license when she was charged with a DWI this spring found a creative way of getting around campus. Tara Monroe, 20, is a student at the University of Texas at Austin. She had her driver's license automatically suspended when she refused a breathalyzer test after leaving a Waka Flocka concert on March 4. He dad took her car away and left her with a bike. But that just wasn't classy enough for Monroe. "Riding a bike around campus sucks," she told MySA.com. "Like really sucks." She searched Craigslist to find an alternative and settled on a bright pink Fisher-Price Barbie Jeep Power Wheel toy to help lug her stuff around campus. She named it after the original owner, a little girl named Charlene. The unorthodox ride has turned Monroe into a minor celebrity. Pictures of her slowly making her way around campus in the toy car have been popping up on social media. "This is the best way I could have gotten my 15 minutes of fame," she said. "Basically, it was the best decision I've made in college, yet..." The Barbie Jeep has a 12-volt battery and only goes about five miles per hour. Monroe says she loves the attention she is getting from her immature hijinks.
