According to a report in Automotive News, Chrysler is preparing to adopt direct injection and turbocharging in an effort to improve fuel economy and enhance the output of its Pentastar V-6 family of engines. Referred to as the Pentastar Upgrade—or PUG for short—the revised engines are element of the maker’s strategy for meeting tightening CAFE requirements.According to the AN‘s source, the initial engine to benefit from the program will be Chrysler’s ubiquitous 3.6-liter V-6, the updated version of which is slated to debut in late 2015 as element of a mild refresh of the Grand Cherokee. Subsequent up will be a reworked 3.2-liter V-6, which is scheduled to arrive in the redesigned Chrysler Town & Country minivan sometime in 2016. Mated to a 9-speed automatic transmission and taking benefit of the new minivan’s (alleged) improved aerodynamics and weight reduction, fuel economy for the T&C is expected to improve by at least 25 percent more than the present model’s EPA ratings of 17 mpg city and 25 mpg highway.
The V-6 Jeep Grand Cherokee (2014 model shown) could soon pack direct injection.
It is not the least bit surprising that Chrysler would contemplate adopting technology that is grow to be basically commonplace across the industry, and the positive aspects of undertaking so will reach across the corporate umbrella. At present, the 3.6-liter V-6 Pentastar is accessible in the Jeep Wrangler, Ram 1500 pickup, Chrysler 200, Chrysler 300, and Dodge Charger, amongst other individuals. If the reworked engines can aid Chrysler achieve fuel-economy gains equivalent to the projected figure quoted for the Town & Country, they would go a lengthy way in keeping the automaker’s CAFE numbers on an upward trend. Plus the thought of a twin-turbocharged, 400-plus-hp V-6 Dodge Charger tends to make us a tiny giddy, even if it might cause havoc among the Dodge brand’s Hemi-dominated horsepower hierarchy.
The supply also indicated that Fiat’s MultiAir variable valve timing technologies will continue to be utilised elsewhere, but “other naturally aspirated engines in the Fiat-Chrysler lineup are also getting regarded as for turbocharging.” This news dovetails nicely with the anticipated arrival of the 2017 Dodge Dart SRT, which likely will pack all-wheel drive and a turbocharged version of the Tigershark 4-cylinder.
