Kia has launched factory-fitted CNG versions of the Carens and Carens Clavis, priced from Rs 12.11 lakh, ex-showroom — the first time CNG has been offered on the Carens directly from the factory rather than as a dealer-fitted kit.

It also arrives days after Kia’s Sorento launch, part of a broader wave of factory CNG additions across the industry this month. Here’s what buyers actually get with these new variants, and where the trade-offs lie.
