Chrysler announced today that the 2011 Dodge Challenger will receive its brand new V6 Pentastare engine. According to the manufacturer, the 2011 Challenger will be equipped with a higher horse power version of the 3.6-liter V6 Pentastar capable to deliver 305 hp at 6350 rpm (with 55 more hp than the current 3.5-liter V6) and a maximum torque of 268 lb.ft. at 4800 rpm. “From day one, our objective with the new Pentastar V-6 engine always was to develop an engine that was capable of producing more than 300 horsepower,” according to Lee. “What we’ve done is adapt proven technologies to this new V-6 engine to bring even more power to Challenger for 2011”.
Regarding the new engine, the new 60-degree 3.6-liter V6 is actually with 94 mm shorter than the 3.7 engine that was previously used in the Jeep Grand Cherokee. This means that on the Challenger, Chrysler engineers were allowed to improve both the intake flow and exhaust flow resulting in more power.
Exhaust valves are 30mm in diameter and canted at 18.8 degrees. Combustion chamber volume is 52.7cc. The new engine will also be found on the 2011 Dodge Charger, but on this vehicle it will deliver “only” 292 hp.
