when it first appeared in November 2011. Honda's stated goal at the time of introduction was to have the most fuel efficient engines in every class in which they are present by 2014 and to achieve a 30 percent reduction in CO₂ emissions across all of their vehicles by 2020 – which is why the engine family was marketed under the "Earth Dreams" Technology moniker. The second generation (S07B) appeared in 2017; it has the same overall displacement but is of a long-stroke design.

S07

Thanks to a lesser bore pitch, the engine could be made shorter. Combined with thinner walls in the block and elsewhere, such as the camshaft, the weight of the S07A was reduced by about 15 percent compared to the preceding P engine. Two versions of the S07A were available, one naturally aspirated and one

turbocharged In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the ...

S07B

The S07B first appeared in the second generation N-Box in September 2017. It has a significantly longer stroke of , which combines with a narrower, bore to provide a near identical displacement to that of the S07A. While power outputs are also near identical, the naturally aspirated engine is equipped with an i-VTEC variable valve timing and lift mechanism and continuously variable valve timing control mechanism, and the turbo engine is equipped with an electric wastegate valve.
