As far as I know there have been three auto-related projects with the name ‘Phoenix’ so far. First and most important to us Malaysians is of course, Proton’s new engine range which will include a turbocharged variant. And then we have Mitsubishi’s Project Phoenix which was supposed to be a detailed plan to close Mitsubishi’s last plant in Australia. And then of course we have Chrysler’s Phoenix engine, now officially known as the Pentastar V6. Quite a popular name isn’t it? But none of these auto projects have anything to do with each other, especially Proton’s and Chrysler’s.
Chrysler claims the new Pentastar V6 is the most advanced V-6 engine in the company’s history, but is that really surprising considering pushrod V6 engines are still in use in the company’s fleet? It will replace as many as 7 current Chrysler V6 engines used in the group’s cars. The first application of this engine will be in the all-new Jeep Grand Cherokee, due out Q2 this year. More variants with better tech like Fiat Multi-Air, direct injection and turbocharging will come later in order for it to replace larger engines.
But for now what we have is a 3.6 litre normally aspirated V6 which makes 290 horsepower at 6,350rpm and 353Nm of torque at 4,300rpm, which represents an increase of 38 percent in horsepower and 11 percent in torque over its predecessor while providing an 11 percent fuel economy improvement.
It’s a twin cam engine with a high-pressure die-cast aluminum cylinder block in a 60-degree configuration and a redline of 7,200rpm. 90% of its peak torque (over 300Nm) is available between 1,800 to 6,350 rpm, which is pretty good and it’s also E85 flexfuel capable. This engine will also be used by larger Alfa Romeos and Lancias.
