If you’re a vehicle enthusiast or keen on Fiat Chrysler Automobiles (FCA) , you might have observed one engine, 3.6L Pentastar V6 engine, can be used on a number of vehicles produced by FCA.
Actually, ten FCA models varying in the Dodge Charger to Ram 1500 to Chrysler Pacifica to Chrysler Pacifica Hybrid towards the Jeep Wrangler, or even a couple of more, have the ability to a 3.6L Pentastar engine around the selection, but exactly how? All of individuals vehicles are extremely not the same as each other, and every one has another gas mileage and convey another quantity of horsepower and torque? We’ll explain.
The engine is definitely an award-winning 3.6-liter Pentastar V6 24-valve dual overhead cam (DOHC) gasoline engine that has been around since 2011 because the Chrysler Pentastar engine. The engine also offers VVT (variable valve timing), that is a newer engine technology that adjusts the timing from the intake and/or exhaust valves to enhance the engine’s efficiency.
Aside from the brand new Chrysler Pacifica and Pacifica Hybrid, the three.6L Pentastar engine has got the same bore and stroke (96 mm x 83 mm) and compression ratio (10.2:1) on all vehicles. The horsepower and torque each model’s engine is slightly various and these small changes could be related to the conventional transmission, and sizes from the stock exhaust and headers.
However, the three.6L engine within the new Chrysler Pacifica includes a compression ratio of 11.3:1 and also the 3.6L engine within the Pacifica Hybrid includes a compression ratio of 12.5:1, which raises the very first reason behind performance variations.
The rise in both engine’s compression ratios is a component that helps you to make both versions from the 3.6L Pentastar engine more fuel efficient compared to other 3.6L Pentastar engines.
Overall the Charger in general includes a better gas mileage, however the Pacifica’s engine is much more fuel efficient. The Pacifica is an even bigger vehicle compared to Charger, so its engine is really more effective so that you can provide it having a gas mileage that’s nearly as good as a vehicle that’s a lot smaller sized. Quite simply, should you remove both engines and insert them in the very same vehicle, the automobile using the Pacifica’s 3.6L Pentastar engine could be more effective compared to vehicle using the Charger’s 3.6L Pentastar engine.
