GENERAL DISCUSSION Kerala

Why does Kerala still avoid diesel cars? Genuinely asking.

Was chatting with a dealer in Kochi last week who said diesel bookings have quietly dropped to almost nothing on his floor compared to five years ago, and it got me thinking about why, specifically here. The obvious answers are the ones everyone already knows — BS6 Phase 2 pushed diesel engine costs up close to petrol-hybrid pricing, the fuel price gap between petrol and diesel has narrowed a lot compared to a decade ago, and resale on diesel hatchbacks has softened noticeably. But Kerala also has its own local reasons that don't apply the same way in, say, Delhi or Mumbai — we don't really do the kind of high-annual-mileage highway driving where diesel's efficiency edge used to pay for itself, most commutes here are short and urban, and diesel particulate filters apparently don't love constant short-trip city driving (something about not reaching regeneration temperature often enough, a mechanic explained it to me once but I didn't fully follow it). Is that the real reason, or is there something more specific to Kerala buyers I'm missing? Curious what people who've actually owned both are seeing — anyone switch from diesel to petrol or hybrid recently and regret it, or not regret it at all? Also curious if the ghat-road crowd (Munnar/Wayanad regulars) still swear by diesel torque for those climbs, since that's the one argument I keep hearing in favour of sticking with it.
