Mazda is working on the second and third generation of its SKYACTIV-G engine, and the latter (expected to launch by 2020) will have even lower well-to-wheels CO2 emissions than current electric motors, according to the company.
Mazda's SKYACTIV engines already rank among the cleanest and most fuel-efficient on the market, and can help meet the new emissions standards without the use of a hybrid system.

Their compression ratio will reportedly increase from 14:1 to 18:1 with the second generation. Mazda will also employ homogeneous charge compression ignition (HCCI), a system that works pretty much like a diesel engine, using piston compression rather than a spark plug to ignite the mixture in the chamber.
Meanwhile, the third generation of SKYACTIV will adopt adiabatic combustion to prevent the loss of heat in combustion, dropping well-to-wheels CO2 emissions to around 60g/km on average.
But that's not all: Adding a mild hybrid system based on the current i-Eloop device could further reduce well-to-wheels CO2 emissions to just 50g/km, which is the equivalent of a pure electric model, according to Mazda’s calculations.
