THE biggest single change in the CR-V is the increase from a 2.0-litre non-VTEC engine to a 2.4-litre i-VTEC engine. Apart from the increase in capacity, the difference is really the i-VTEC technology. Variable valve timing gives the engine a greater power and torque range as well as improved fuel economy and lower emissions. The i-VTEC engine employs two technologies: VTEC - a mechanism for switching cams between low and high-speed ranges and VTC - a cam phase control system based on engine speed and load. The result is an engine that performs well under most situations. Around town there is plenty of torque available to move with the traffic, without the need to work the gears hard, and on the highway there is plenty of top-end power to overtake safely. The engine is quiet and revs freely to the higher end of the scale with no noticeable vibration.
