Greenway Jeep,Chrysler,Dodge First Look at The New 3.6L V6 Pentastar Engine for 2011 Grand Cherokee

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) April 14, 2010 --

Ever since the Chrysler Corporation was organized in 1925, Chrysler has made a quality product with quality engines. Engine technology has come a long way since 1925 and Chrysler is right on top of the new technology coming out. You can see this very clearly in the new 3.6L Pentastar V6 engine from Chrysler, the engine going into the 2011 Jeep Grand Cherokee. The new Phoenix / Pentastar engines a generation ahead of anything currently available. Power ratings for the Jeep Grand Cherokee will be at least 280 horsepower and 260 lb.-ft. of torque @ 4,800 rpm; the engine uses a chain drive instead of a timing belt for greater longevity and accuracy. The engine features high-flow intake and exhaust ports, which in combination with Variable Valve Timing via dual independent cam phasing, allows optimum volumetric and combustion efficiency over the full speed and load range. This results 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 provides outstanding drivability and responsiveness.

The idea was to achieve a quiet yet powerful engine with convenience for the consumer in mind. The engine accessories have no brackets; they are bolted directly to the block, cutting vibration. Since the air conditioner compressor and alternator are both bolted to the block, a tensioner is used with the serpentine belt to maintain appropriate tension. The Pentastar V6 is an interference design; it has valve reliefs but only for clearance under normal conditions. It does have a timing chain, reducing the possibility of heavy damage from a snapped belt. Spark plugs are installed at the end of a length tube. There is a spring running through the length of the tube, from the conventional-looking plugs up to the coils. The Phoenix engine was designed to be used in either a North-South and East-West configuration. Refinement was achieved with the help of advanced computer-aided engineering. Structural, intake, and exhaust areas deliver low levels of noise. Idle quality was improved through the dual independent cam phasing. A twin turbo and single-turbocharger version are planned, for introduction by 2014; both would be based on the smallest size (3.0 liters) and might be slated for limited-production models (e.g. a new Viper based on a Maserati or an SRT mid-sized car). The twin-turbo version appears to be projected for a whopping 420 horsepower while the single-turbo appears to be set for 370 hp.
