The 2015 jeep patriot engine 2.0l 4 cylinder has Dual Variable Valve Timing (VVT) technology, which optimises the timing of the intake and exhaust valves to maximise fuel efficiency and power output. This VVT technology enables the engine to react to driving conditions, changing performance based on acceleration or cruising speed. This blend of power and efficiency is appropriate for the Patriot's role as a practical, flexible SUV that can handle a wide range of driving situations.
