While it may sound hard to believe, there’s actually some sense to be made in what was said by Mazda, when they announced that next-gen SKYACTIV engines will be so green that they will emit less CO2 than what is emitted in order to charge an electric vehicle.
As
you’d imagine, the statement itself is so vague that it could be made
to sound true, even if it wasn’t. However, we don’t need to do that,
because it can be backed up with actual arguments, according to GreenCarReports.
They
explain that if these new engines really do emit 30 percent less than
what we’re measuring now, then in some cases, where the local power grid
is run by burning coal, for instance, then yes, the statements holds
true.
It all depends on how the power
is produced, and it should be something to be considered if you want to
go out and buy an EV. If all you’re doing is simply moving the source
of the pollution to the power plant, that’s obviously not really what
the dictionary would call a solution.
However,
making such statements official is a bit too much, and Mazda should
concentrate on actually reaching its efficiency and emissions goals,
instead of telling us that they’re aiming for them years in advance. It
plans to increase the current compression ratio of its SKYACTIV engines
from 14:1 to 18:1 and try to make the unit run more like a diesel by
incorporating elements of homogenous charge-compression ignition (HCCI).
These new SKYACTIV units will make their global debut around the year 2020.
