Pentastar 3.0 revealed

by David Zatz on

Chrysler revealed the 2997 cc version of its Pentastar V6 engine in China, where it will power the Jeep Grand Cherokee and Wrangler, with other vehicles presumably on the list to use the new engine later. Just-Auto revealed that, as Allpar wrote earlier, 3.0 production has been going on for some time, starting on July 3. The engine is made in Trenton, Michigan.

The new engine is rated at 230 horsepower at 6,350rpm, with peak torque of 210 lb-ft at 4,400 rpm. The 3.2, in comparison, 271 hp and 239 lb-ft.

The primary purpose of the 3.0 liter V6 is to avoid displacement taxes; in the Europe Union and China, where oil supplies are limited for various reasons including lack of domestic production, vehicles with engines of 3.0 liters and more are penalized with higher taxes. Thus, the new variant was designed to be 2.997 liters, falling below the cutoff.

Like its bigger siblings, the 3.0 has a die-cast-aluminium cylinder block, structural windage tray and oil pan, directly mounted accessories, timing drive with inverted teeth, and select-fit pistons with polymer graphite coated skirts. A new intake manifold has “low-rumble tuning,” according to Just-Auto.  The connecting rods are forged steel.  ( Just-Auto article. Pentastars.com details on the engines. Thanks, “humdrum.”)
