Class-leading power and fuel efficiency
High performance and low fuel consumption in a single engine

i-VTEC regulates the opening of air-fuel intake valves and exhaust valves in accordance with engine speeds

By regulating valve opening to match engine speed, the agile i-VTEC engine adjusts its characteristics to realize both superior power and low fuel consumption.

The new 1.3L i-VTEC engine is agile and intelligent: at low engine speeds one of the two intake valves is idled. The engine sips gasoline, using a lean fuel mix at low engine speeds for further improved combustion efficiency.
