DZire

Maruti Suzuki launched the third generation DZire sedan in India on 16 May 2017. It is based on the fourth generation Swift but, for the first time ever, it drops the Swift badge from its name. The second-gen DZire will still be in production and will be sold exclusively to fleet operators, while being rebadged as the next generation Swift DZire Tour.

The third generation Maruti DZire is based on the HEARTECT lightweight platform derived from the Maruti Baleno and the fourth generation Swift. This platform uses Ultra-high tensile and high tensile steel in its construction, so as to not comprise on structural rigidity. Despite being lighter, Maruti claims that the new DZire is compliant with frontal and side impact regulations, as well as meets pedestrian safety regulations. The car is also wider and offers increased space for the occupant. Maruti claims that the third generation DZire has 55 mm better rear legroom, as compared to the previous model. Moreover, the boot space has been increased to 378-litre.

The engine options on offer at launch include a 1.2 L K12B motor producing 82 bhp and 113 N m of torque, while the diesel gets the 1.3 L DDiS motor with 74 bhp and 190 N m of torque. Both engines can be had with a 5-speed manual or 5-speed AMT (from V grade onwards), meaning there will be no drop in the fuel efficiency of the automatic variants, as compared to the manual variants. The petrol models deliver 22 km/L and the diesel models are rated at 28.40 km/L in the fuel economy department.

The third generation DZire was launched for sale on 16 May 2017 in India. It will rival the recently launched Hyundai Xcent, Tata Tigor, Tata Zest, Honda Amaze, Toyota Etios, Mahindra Verito, Ford Aspire and VW Ameo.

Of the four million units, units sold in India account for approximately half of them. Also, approximately 19% were sold in Europe, and approximately 11% were sold in Japan. By June 2008, cumulative sales of the Swift reached 1 million and in January 2011, cumulative sales totaled at 2 million.
