- 2022 2.5GT
Change is a constant these days in the automotive world. It should be reminded to all that the 17 came with improvements to the engine including assymetric pistons and new oil control rings that are bi-directional and total new design. I saw the video with Dave Coleman describing all this but I cannot find it now. The crankshaft is offset as well.
Major changes? It depends on your perspective. Cylinder deactivation can be called major but since Mazda did it, Ford and another brand are doing the same with some of their 4 bangers. So it seems to be a growing attribute in four cylinder engines.
Ive got some PDFs you might find interesting. Quite interesting how they achieve CD.
