New York — Chrysler LLC introduced today an all-new line of V6 engines that will improve fuel efficiency across the Chrysler, Jeep® and Dodge lineup by 8 percent on average compared with previous Chrysler V6 engines. This more refined and fuel-efficient V6 engine will ultimately replace seven current Chrysler V6 engines.
The new 3.6-liter V6 engine — named Pentastar — is part of the company's overall $3 billion powertrain offensive. It will first be offered in the all-new 2011 Jeep Grand Cherokee, unveiled today at the New York International Auto Show and at the Jeep Safari in Moab, Utah.
“Chrysler's all-new 3.6-liter Pentastar V6 engine will offer our customers improved fuel economy, refinement and increased performance across the Chrysler, Dodge and Jeep vehicle lineup,” said Frank Klegon, Executive Vice President — Product Development, Chrysler LLC. “At the same time, replacing seven current engines with one engine will result in increased flexibility, more efficient operations and significant cost savings to the company.”
The Pentastar is an all-new design, featuring double-overhead camshafts (DOHC) and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration.
In the all-new 2011 Jeep Grand Cherokee, the all-new 3.6-liter Pentastar V6 engine will deliver 280 horsepower (209 kW) at 6,400 rpm and 260 lb-ft (353 Nm) of torque at 4,800 rpm — an increase of 33 percent in horsepower and 11 percent in torque over its predecessor — while providing an 11 percent fuel economy improvement.
“The all-new Pentastar is the most advanced six-cylinder engine Chrysler has ever offered,” said Bob Lee, Vice President — Powertrain Product Team. “This new family of engines uses an architecture conceived with future technology growth and integration in mind.”
The new Pentastar V6 also will contribute a 2 mpg increase to Chrysler's CAFE by 2015, resulting in fewer greenhouse gas emissions and a reduction in oil dependence.
Customers Benefit: Fuel Efficiency, Refinement, Quality, Low Cost of Ownership
During the initial goal setting for the Pentastar program, Chrysler engineers benchmarked the industry's leading engines to set functional targets. The result is an all-new engine that delivers truly world-class customer attributes.

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.
