Chrysler Launches Pentastar V6 at Trenton Engine

Although we’ve been noting lately the investments in electric vehicle powertrains (e.g., this), we would be remiss if we didn’t point out that actions are continuing apace in the more conventional engine arena.

Case in point: Today Chrysler Group launched the 3.6-liter Pentastar V6 engine in the Trenton South Engine Plant (TSEP) in Trenton, MI.

The engine launch represents a $730-million investment. The 822,000-square foot manufacturing facility will have an annual capacity of approximately 400,000 engines when in full production.

“The Pentastar engine is a cornerstone of Chrysler’s efforts to re-invent its business model with strong-brand-focused, world-class quality products,” said Scott Garberding, head of Manufacturing, Chrysler.

The Pentastar engine will debut later this year in the 2011 Jeep Grand Cherokee. In that application it will provide a 33% increase in horsepower and an 11% increase in torque compared to the existing V6 in the current-generation Grand Cherokee.

The Pentastar producess 280 hp @ 6,400 rpm and 260-lb-ft of torque @ 4,400 rpm.

The engine is designed so that it can accommodate technologies including Multiair, direct-injection, and turbocharging. The Pentastar is replacing seven current V6 engines, thereby providing Chrysler with flexibility, efficiency and significant cost savings.
