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

April 10, 2010 - PRLog -- 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.

Chrysler wrote that: “The new Phoenix of V-6 engines will feature cylinder deactivation (MDS)...the engine will operate efficiently on three cylinders when less power is needed, and in V-6 mode when more power is needed. This optimizes fuel economy when V-6 power is not required – without sacrificing vehicle performance or capability. The new family of V-6 engines will feature an aluminum die cast block, dual variable valve timing (VVT) and a two-stage oil pump, among other technologies. The end result is an expected across-the-board V-6 fuel efficiency improvement of six to eight percent – in addition to new levels of V-6 power, performance and refinement.”

   Chrysler incorporated convenience for DIY oil changes with the new advanced oil filter system which eliminates oil spills and contains an incinerable filter element instead of the typical spin-on filters, which are disposed of in landfill sites; the filter is conveniently located on top of the engine. The use of long-life spark plugs, regular gasoline, and a high-energy coil-on-plug ignition system also helps to reduce cost of ownership. The engine also is fully flex fuel capable, offering consumers the choice of gasoline or E85 fuel without any degradation in performance or emissions. Running on regular gas, the Pentastar engine is estimated for 16 mpg city, 23 highway on the Grand Cherokee — vs 16/20 for the Hemi. It meets California LEV II+ evaporative emission requirements, Tier 2, meets Federal Bin 4+ emission requirements, and Clean Fuel Fleet Certification (CCF-LEV) in all other states.

   According to Chrysler presentations, even the most powerful Phoenix, displacing 3.6 liters and producing (in preliminary tests) over 280 horsepower, is quieter than Toyota’s 3.3 liter V6 - and far quieter than the Toyota 3.5 liter V6. Gas mileage is said to be good, partly due to the use of high-pressure, die-cast blocks, which save on labor and allow for thinner walls and less use of aluminum. These blocks are 20 pounds lighter than General Motors‘ V6 blocks, saving around $40 per engine on aluminum alone; an independent firm estimated that these engines are at least $300 cheaper to build than GM’s current V6 line. The new state-of-the-art Trenton (Mich.) Engine South plant will be the lead facility for production of the Pentastar V-6 engine. A duplicate facility in Saltillo, Mexico, will ramp up for the 2012 model year. Production is scheduled for 2010. At this point, it appears that 440,000 Pentastar engines are to be made this year. Point in case Chrysler has been making engines for 85 years now and their experience is proven with their new Pentastar engines and all the technology has research that was put into them. Chrysler remains a top of line engine designer and manufacturer.
