When Honda developed their first VTEC engine, it came from their racing heritage: we saw the technology implemented in the legendary Integra Type R, as well as several other high-speed vehicles. When the RSX hit the market, we saw the emergence of “intelligent VTEC”, or i-VTEC for short. Honda is getting ready for the next generation, as they are working on what they call “advanced” VTEC, an engine technology that “combines continuously variable valve lift and timing control with the continuously variable phase control of VTC (Variable Timing Control).”
This development is said to not only provide optimal power delivery and efficiency, but also a 13% improvement in fuel economy. Moreover, this new engine is “exceptionally clean”, with 75% lower emissions that those required by 2005 standards. The plan is to see this new a-VTEC engine in a production car within the next three years.
