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 are the cars with the best and worst depreciation after 5 years

The average new vehicle sold in America loses nearly half of its initial value after five years of ownership. No surprise there; we all expect that shiny new car to start depreciating as soon as we drive it off the lot. But some vehicles lose value a lot faster than others. According to data provided by iSeeCars.com, trucks and truck-based sport utility vehicles generally hold their value better than other vehicle types, with the Jeep Wrangler — in both four-door Unlimited and standard two-door styles — and Toyota Tacoma sitting at the head of the pack. The Jeep Wrangler Unlimited's average five-year depreciation of 30.9% equals a loss in value of $12,168. That makes Jeep's four-door off-roader the best overall pick for buyers looking to minimize depreciation. The Toyota Tacoma's 32.4% loss in initial value means it loses just $10,496. The smaller dollar amount — the least amount of money lost after five years — indicates that Tacoma buyers pay less than Wrangler Unlimited buyers, on average, when they initially buy the vehicle. The standard two-door Jeep Wrangler is third on the list, depreciating 32.8% after five years and losing $10,824.

On the other side of the depreciation coin, luxury sedans tend to plummet in value at a much faster rate than other vehicle types. The BMW 7 Series leads the losers with a 72.6% drop in value after five years, which equals an alarming $73,686. BMW's slightly smaller 5 Series is next, depreciating 70.1%, or $47,038, over the same period. Number three on the biggest losers list is the Nissan Leaf, the only electric vehicle to appear in the bottom 10. The electric hatchback matches the 5 Series with a 70.1% drop in value, but since it's a much cheaper vehicle, that percentage equals a much smaller $23,470 loss.

2018 Jeep Wrangler will keep classic hood style

One of our spy photographers caught some FCA employees poking around under the hood of a 2018 Jeep Wrangler prototype. They had the hood open wide, and because of that, we can catch a couple little details that tell us a bit more about the exterior styling of the Wrangler. Mainly that some of the Wrangler's signature hood details will remain for the new generation. The first details we caught were the bolt holes in the hood at the base near the hinges. These show that, as with the previous model of Wrangler, the 2018 model will feature chunky, rugged-looking external hood hinges. We can also infer that if these hinges remain, the doors will likely have matching ones, and those will hopefully still be removable. The second details we spotted were a bit more subtle. On the sides of the hood towards the leading edge, there are some indentations. Based on the positioning, and their small size, we believe these are the indentations for external tie-down latches for the hood, just like the old model. Actually, just like pretty much every Wrangler-style Jeep back to the military models used in World War II. Based on a report last week from JL Wrangler Forums, we are expecting to see the fully revealed 2018 Jeep Wrangler and its classic hood details at this year's LA auto show. It is then expected to arrive at dealers in December with both V6 and four-cylinder engine offerings.
