The 1.3-litre diesel engine that powered the Ertiga is also available in other Maruti Suzuki cars like the Vitara Brezza and Dzire. This engine won’t be upgraded to meet BS6 emission norms that come into effect from 1 April 2020. As a result, it will be removed from all existing Maruti Suzuki cars.

While Maruti Suzuki has announced that it will not upgrade the 1.5-litre diesel engine to meet the BS6 emission norms right away, the carmaker says that if it sees demand for diesel-powered cars in the BS6 era, it would upgrade the new 1.5-litre diesel engine to meet the emission standards.

Before the discontinuation of the Ertiga 1.3D, it was available in L, V, Z and Z+ variants. The price of these variants (barring the L, Ertiga 1.5D is not available in L variant) was lower than the same variants with the 1.5-litre diesel engine by around Rs 30,000. The diesel Ertiga now starts at Rs 9.87 lakh and goes up to Rs 11.21 lakh (both prices ex-showroom, Delhi).
The upcoming Maruti Suzuki XL6, which is essentially a spruced up version of the Ertiga, will come powered by the 1.5-litre petrol engine only. It is expected to be more feature-rich than the Ertiga, and, therefore, is likely to be priced higher.
