It has to be the K10B in the new WagonR. The main reason for these heart transplants maruti is doing now is the BS-4 enission norms it will have to meet from April next year.
So i dont think Maruti will ever plonk the K12B inside the WagonR and pose a threat to the Ritz.
The exterior dimensions up front may change a little. To accomodate the new engine. I heard the K series engine is taller than the WagonR's current 1.1Lt engine. (same must be reason for the Estilo's facelift) |
