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 will build old Wranglers next to new ones in Toledo

Jeep made a lot of people happy when it confirmed that the next-generation Wrangler would continue to be built in Toledo, OH. Now, news is breaking about the lengths the automaker will go to in updating its northern Ohio factory. There's good news for Jeep dealers (more Wranglers to sell!), Jeep fans (more JKs to buy!), and Jeep itself (more money to be made!). According to a report from Automotive News, capacity at the factory will be increased to 350,000 units per year. That's around a 50 percent increase over what the Toledo complex can currently manage and is, according to Jeep boss Mike Manley, part of a move to keep production "at the right place" so "supply [stays] just behind demand." The other big news revealed by the AN report focuses on the future of the current Wrangler. Yes, the current JK has a future. It'll continue to be built at the Toledo factory up to six months after it successor arrives in showrooms, a move that's partially down to the way Jeep is shuffling production about. Toledo currently builds the Cherokee on a unibody production line – it'll continue to do so until March of 2017, when production will move to Belvidere, IL. The unibody line in Toledo will then be converted for body-on-frame production, which should take about six months. But during that time, the current JK (likely rebadged as a "Wrangler Classic") will continue to be built alongside another line of next-generation Wranglers, keeping dealers supplied with the today's Wrangler through March of 2018. The two Wranglers will overlap for about six months. This is all very good news if you've been waiting to pull the trigger on today's Wrangler. But move quickly – the clock is officially ticking.

MotorWeek reviews '83 American Motors lineup

The 30th anniversary of American Motors' 1987 sale to Chrysler by Renault is just a few years away. AMC is long dead, but for its latest peek in the archives, MotorWeek winds back the clock to somewhat happier times. Take a look at the entire AMC lineup from 1983, including its models from Jeep and Renault. The Jeeps, and to a lesser extent, the AMC Eagle, enjoy a cult following today, but it's amazing how many of these other vehicles are now practically forgotten. Even the big debut in '83 of the Renault Alliance is largely ignored. Although with a ludicrous amount of body roll and a 55-horsepower 1.4-liter engine, it's probably rightly buried.
