I don't know. Any article that starts with something like "We did, however, speak with Mazda bosses who hinted at the following interesting information" immediately raised the speculation red flag. I also see lots of "litres" and references to the British pound (currency), which says if any of that is true it applies to Europe and what we see may be markedly different.
I wonder how closely the 2.0L will resemble the 2.0L in the 3. I can assume the 2.0L and 2.5L in the 3 have the same engine mounting points so perhaps it stands to reason a 2.5L swap into the new MX-5 is feasible? Anyone know how the 2.0L or 2.5L Sky-Activ engines are taking to power mods?
