MORE THAN JUST SPIN

Wheels (Australia) - - 2017 Car Of The Year -

In mak­ing the change to a turbo-petrol four for CX-9, Mazda’s en­gi­neers needed so­lu­tions to en­sure vir­tu­ally zero lag and ap­pro­pri­ately crisp throt­tle re­sponse. It came with the in­tro­duc­tion of a raft of mea­sures, in­clud­ing a man­i­fold de­sign that, at low revs, har­nesses the en­ergy of the in­di­vid­ual ex­haust pulses from each cylin­der to keep the tur­bine spin­ning, thus re­duc­ing lag. Also help­ing is a su­per-high 10.5:1 com­pres­sion ra­tio, which re­quired in­no­va­tive cool­ing tech­niques to avoid det­o­na­tion. Up­shot? It works: this is a bril­liantly re­spon­sive en­gine.
