Maruti Suzuki is planning to introduce its newly developed 1.5-litre diesel engine in the Ciaz in February 2019. Select Maruti Suzuki’s Nexa dealerships are already accepting bookings for the Ciaz 1.5D models for Rs 11,000. The bigger 1.5-litre engine won’t be on offer on the Ciaz Sigma for now, so the entry-level diesel Ciaz will be powered by the 1.3-litre engine only. The 1.5-litre diesel engine will eventually replace the current 1.3-litre diesel engine, but Maruti Suzuki has no plans to immediately discontinue the smaller engine on the Ciaz.
The new 1.5-litre diesel engine will be called the DDiS225, as it will produce 95.1PS of power at 4000rpm and 225Nm of peak torque between 1500-2500rpm. That’s a marginal increase of 5.1PS/25Nm over the existing 1.3-litre (90PS/200Nm) unit, which is called the DDiS200. The new diesel engine will return a claimed fuel efficiency of 26.82kmpl, which is 1.27kmpl less than the existing 1.3-litre diesel, but more than that of its rivals.
Sources aware of the development have informed CarDekho that the 1.5-litre diesel engine on the Ciaz will not get the mild-hybrid SHVS system. Both the current 1.5-litre petrol and the 1.3-litre diesel units on the Ciaz and the Ertiga are available with SHVS mild hybrid system. But while the 1.3-litre unit gets the older single-battery hybrid system, the 1.5-litre petrol engine is equipped with a dual-battery (one is Li-ion) hybrid system.
The new 1.5-litre diesel engine will be paired with a new 6-speed manual transmission. At present, all manual transmissions on Maruti cars are 5-speed units only. Even though the new 1.5-litre unit won’t be BSVI-compliant at launch, Maruti will upgrade it post April 2020 to comply with the latest emission norms. After Maruti debuts the new 1.5-litre engine with the Ciaz next month, expect to it make its way to the Ertiga and other cars later this year.
