Chrysler's all-new 3.6-liter Pentastar V6 engine design features a double-overhead cam (DOHC), narrow included valve angle, cylinder head and high-flow intake and exhaust ports. This design, combined with dual independent cam phasing, allows optimum volumetric and combustion efficiency over the full speed and load range, resulting in an exceptional, flat torque curve along with high specific power — the engine's torque exceeds 90 percent of its peak value from 1,600 to 6,400 rpm — which will provide customers with outstanding drivability and responsiveness, without the need for premium fuel.
“Similar to what we did with the HEMI® engine, our engineers used the best combination of design features and technologies to create an engine that satisfies customer requirements,” Lee added. “The elegantly simple design maximizes the functionality of each design element rather than adding technology to claim a feature. The result gives our customers everything they demand from an engine today — class-leading levels of refinement, fuel-efficiency, performance and cost of ownership.”
The advanced oil filter system eliminates oil spills and contains an incinerable filter element — more efficient disposal than the typical spin-on filters, which are disposed of in landfill sites. The use of long-life spark plugs and a high-energy coil-on-plug ignition system also helps to reduce cost of ownership.
The Pentastar V6 is designed to run on regular gasoline, offering a 10 percent reduction in fuel cost compared with premium fueled engines. The engine also is fully flex fuel capable, offering consumers the choice of gasoline or E85 fuel without any degradation in performance or emissions.
The new state-of-the-art Trenton (Mich.) Engine South Plant will be the lead facility for production of the Pentastar V6 engine. A duplicate, new facility in Saltillo, Mexico, will ramp up for the 2012 model year.

I truly believe that engines that use alternative fuels like E85 are here to stay and for hot rod guys such as myself, it is nice to be able to get 105 octane fuel at the pump.
Thanks for the informative article about Chrysler's new breed of engines.
