Pentastar V6 tech, Ram launch

by David Zatz on

Pentastar V6

A new article published by the Society of American Engineers, written by Paul Weissler, notes that the 3.6 liter Pentastar V6 has four variants, three for varying drive systems (AWD, RWD, FWD) and one for the Dodge Challenger; all use the same internals, including the camshaft and pistons. The differences are the intake manifolds and heads, and there are only two varieties of each so far. The article notes that the Challenger’s 13 horsepower increase is due to “a more aggressively designed intake air system” which increased airflow from 214 to 220 g/s.

The article also confirmed reports at Allpar and pentastars.com that the project was temporarily dropped by Cerberus, and that the future holds a 3-liter turbocharged version and possibly Multi-Air. Weissler reported the capacity of the twin engine plants at 440,000 each, with volume rising sharply in calendar-year 2012 (which presumably dates the use of the engines in Ram trucks).
