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.

2015 Chrysler 300 First Drive [w/video]

When Chrysler last updated its 300 in 2011, the fullsize sedan market was a very different place than it is today. Ford's redesigned Taurus was in showrooms, sure, but segment stalwarts like the Toyota Avalon and Chevrolet Impala were languishing at the tail end of their model cycles. And still, the second-generation 300 (not counting the "letter series" cars from the 1950s and '60s, of course) failed to recapitulate the booming success of the model reboot in 2004. Something in the combination of the down economy, higher gas prices and great product from front-wheel-drive entries in the class kept the 300 from the six-digit sales numbers it saw in the early 2000s. For the 2015 model year, Chrysler hopes that a more clearly defined purpose for its big sedan, combined with liberal dipping into the corporate tech toy box, will rekindle buyer interest. Considering the mild characters and front-driver dynamics of its mainstream competition, the promise of V8 power and rear-wheel drive should at least turn the heads of those looking for a car with a little edge. I grabbed the keys of the edgiest of the bunch, the sport-intended 300S, and found a big sedan that gives away some practicality to the rest of its segment mates. The trade-off for the dip in pragmatism is an uptick and driving fun and attitude that should make all the difference for the right buyer. Even though the hard-to-miss face of the 300 has come in for another nip and tuck, that attitude is still clearly on display, too. The grille of the 300 is some 33-percent larger than the outgoing model, though it's still far less brutal than the throwback styling of the 2005 "Baby Bentley" car, at least to my eyes. The cheese grater insert is metallic in most trims of the 300, though the 300S you see in my photo set gets the meaner blacked-out treatment. A quick scroll through our gallery will show you that the rest of the 300 has been similarly changed but not reinvented. Light clusters front and rear are revised, the rear clip has been re-forged with less busy styling, and the whole car has been de-chromed to a large extent (this 300S is wearing the least blingy outfit of the bunch). That rear spoiler is S-model specific. I held the existing 300 interior in fairly high regard, and this new car improves on that base.

2017 North American Car, Truck, and Utility of the Year entries announced

Over 40 vehicles will compete for the 2017 North American Car, Truck, and Utility of the Year awards. If that name looks a little strange, it's because the competition added a third category. In years past, pickup trucks, crossovers, SUVs, commercial vans, and minivans competed for the same award. That's why there were occasionally weird comparisons, like last year's competition between the Volvo XC90 and Nissan Titan XD. The new format separates pickups and commercial vans into the truck contest and CUVs, SUVs, and minivans into the utility competition. A complete list of eligible vehicles is below, but here are a few highlights. For one, the entire list of entries has a luxurious lean. Of the 43 vehicles, nearly half of them are from premium brands. There are two eligible Bentleys – the Bentayga and Mulsanne – the Rolls-Royce Dawn, Jaguar F-Pace, Audi Q7, and the Mercedes-Benz GLS-, E-, and S-Class Maybach. The performance ranks are lofty, too, with the Audi R8, Acura NSX, Alfa Romeo Giulia, Mercedes SL- and SLC-Class, Porsche 718, and F-150 Raptor. The mainstream entries are just as comprehensive. From the Chrysler Pacifica to the Chevrolet Cruze to the Fiat 124 Spider to the Mitsubishi Mirage, NACTOY has covered an enormous price range with this year's contestants. Of course, these are only the eligible vehicles. They'll need to run through three rounds of judging, starting in September at NACTOY's traditional Hell, MI, test drive. The Canadian and American journalists involved in the judging will announce this year's nine finalists – three in each category – on December 6.
