NEW YORK — Chrysler announced at the 2009 New York Auto Show that it will be putting an all-new lineup of V6 engines in its 2011 Jeep Grand Cherokee and other Chrysler products. The engine will be the eventual replacement for seven of Chrysler's V6 engines.
Chrysler's all-new Pentastar V6 is claimed to be the "most advanced six-cylinder engine in the history of Chrysler." It's a flex-fuel DOHC 3.6-liter engine that will improve fuel efficiency by as much as 8 percent — and will get Chrysler a 2-mpg increase in CAFE by 2015.
The Pentastar V6 gets a 60-degree die-cast aluminum cylinder block, narrow included valve angle, cylinder head and high-flow intake and exhaust. The engine makes 280 horsepower at 6,400 rpm and 260 pound-feet at 4,800 rpm. Chrysler calls that a 33 percent hp and 11 percent torque improvement over the engine it replaces.
The engine is flex-fuel capable for the use of gasoline or E85 but can also run on regular gasoline. It also gets an "advanced oil filter system" that includes a more efficiently disposable filter element, long-life spark plugs and a high-energy coil-on-plug ignition system, all intended to cut ownership costs.
The new engine will be built at Trenton, Michigan, and at a facility in Saltillo, Mexico, that will start building the engines for model year 2012.
