New Rav4 Engines to be Ultra-Low Friction

by Benjamin Jones on March 3, 2009

Toyota has been stepping up the fuel efficiency game recently, and not just with flashy hybrid models like the new Toyota Prius. Some of their efforts have been to inch up the mileage across their entire fleet with some advanced fuel efficiency upgrades incorporated into their engine design.

The new Rav4 engine is a perfect example Toyota’s advanced engine technology:

  • Dual indepedent variable valve timing (VVT-i)
  • Offset crankshaft
  • Roller rockers
  • Three-stage variable oil pump
  • Reduced-tension piston rings
  • Auxiliary belt drive

Perhaps the neatest upgrade, however, is the Acoustic Control Induction System (ACIS), which changes the length of the intake runners based on operating conditions to deliver the most torque and fuel economy at any given time.

The new engines from Toyota not only promise better fuel economy, but also more power.

I want to buy a new Rav4 and want the new engine, but no Toyota distributor seems to know about it or the date it will be available. I need to change my car very soon – can you let me know when it will be available
