This Ram ProMaster van comes standard with a fuel tank that holds up to 24 gallons of gasoline. A non-locking cap for the fuel tank provides extra convenience for stops at gas stations. The gasoline is burned by a six-cylinder engine block that runs on the Pentastar technology. When pushed to its maximum, the V6 powertrain whips out 280 hp and 260 lb-ft of torque. If you drive this vehicle during the winter season, you should purchase the optional engine block heater that mitigates thermal problems under the hood. Using an oil-based reservoir, an auxiliary cooler works in sync with the automatic transmission system, which creates six fixed speeds.
