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.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).

SUV lifts you up where you belong and leapfrogs traffic jams

So, you're at a dead stop, stuck in traffic, when it pulls up behind you. It appears to be a garden-variety Jeep Grand Cherokee. That is, until its undercarriage lifts the Jeep 9 feet into the air, and the whole rig straddles you and the cars ahead of you in a bid for open road. The car is called the Hum Rider, and no, you can't buy one at the Jeep store. It's a one-off publicity stunt intended to promote Verizon Telematic's Hum platform, which plugs into a car's OBD port and for $10 a month provides vehicle diagnostics, roadside assistance, location tracking, and speed and geo-fencing alerts. (Not sure if Hum tracks vertical leaps.) Verizon enlisted viral marketing agency Thinkmodo to promote the Hum, and this idea was head and shoulders above the rest. "We saw this one [and said], 'Wow, that is crazy,' said Jay Jaffin, Verizon's VP of marketing. "We loved the idea." Thinkmodo co-founder James Percelay told Mashable that they wanted to represent the upgrade Hum brings to cars. So the car goes up. Get it? Here's the star of this story: Hum Rider's designer, Scott Beverly, has done visual effects for Hollywood in The Dark Knight, Inception and Interstellar. He works for A2Zf, a Lancaster, Calif., design and engineering firm that keeps the world filled with Batmobiles, Red Bull Can Cars and beautifully designed VWs and Audis. A2Zf has also worked with NASA on X-planes and with Northrup on the B2 bomber, so compared to those projects, a car-straddling car is hardly a stretch. So what does it take to make a car do this? How about: Over 300 feet of hydraulic lines that operate everything - the lift mechanism, steering, braking and power to the drivetrain. A gas-powered Honda generator under the hood that powers hydraulic pumps pushing out 900 pounds of pressure. A lot of mechanical structure. Hum Rider weighs 8,500 pounds, almost double a standard Grand Cherokee. Heavy-duty truck tires to support all that weight. Four undercarriage cameras that allow the driver to see and clear what's beneath him. What did it cost? They're not saying. What would it be worth, the next time you're stuck in traffic? Priceless.
