Powertrain

All of the 2.0L and 2.4L World Engines feature a heavy dose of high-tech:

  • Intake manifold and exhaust flow control valves
  • Dual Overhead Camshafts (DOHC)
  • Four valves per cylinder
  • Forged crankshaft and connecting rods
  • Aluminum block
  • Acoustic oil pan

Green Alert! The 2.4L DOHC 16V dVVT PZEV I-4 engine is one of the greenest cars on the planet. A Partial Zero Emissions Vehicle (PZEV)[1] is a vehicle that meets Super Ultra Low Emission Vehicle (SULEV) tailpipe emission standards and has zero evaporative emissions from its fuel system. It also features a 15-year (or least 150,000 mile) factory emissions warranty. Rejoice!

There are three available transaxles on Patriot: a five-speed manual, second-generation Continuously Variable Transaxle (CVT2) with AutoStick®, or Continuously Variable Transaxle (CVT2L) with 19.1:1 overall first gear crawl ratio.

AutoStick allows you to tap the gearshift left or right for complete control of six simulated stepped-gear ratios. Or just leave it in drive and let the advanced CVT2 transaxle handle the rest.

    • /shared/2009/patriot/capability/powertrain/primary/engine_module/5speed_manual.jpg

      The five-speed manual transaxle gets a remarkable 23 city / 28 highway miles per gallon[2] when harnessed to either the 2.4L or 2.4L PZEV[3]World Engines.

    • /shared/2009/patriot/capability/powertrain/primary/engine_module/2.0_liter.jpg
  • Electronic Throttle Control

    Patriot now features Electronic Throttle Control (ETC), replacing the mechanical throttle linkage. ETC provides seamless and consistent engine response, improved fuel economy[4] and enhanced integration of vehicle systems — such as the transmission, variable camshaft timing, vehicle speed control and idle speed control.

  • Dual Variable Valve Timing

    The 2.4L and 2.0L World Engines feature dual Variable Valve Timing (dVVT) on both the intake and exhaust camshafts for better all-around performance. The electronically controlled timing produces more power, better fuel economy and smoother, quieter operation than engines without dual VVT. Smart.
