Additional Notes
- The Tata Harrier 2.0 TD (125 kW) DPF, from 2020, carries an AdBlue (DEF) tank capacity of 15 liters, which is a relatively generous reservoir size for a passenger SUV and reflects the demands of the selective catalytic reduction (SCR) system installed on the vehicle.
- A 15-liter AdBlue capacity means refill intervals can be extended compared to smaller tanks, since DEF consumption typically runs at roughly 3-5% of diesel fuel consumption under normal driving conditions.
- The capacity figure of 15 liters is listed under a normal use condition, meaning the specification applies to standard on-road driving rather than severe or heavy-duty operating cycles.
- The presence of a selective catalytic reduction system on the 2.0 TD (125 kW) DPF variant indicates the engine uses DEF injection into the exhaust stream to convert nitrogen oxides into nitrogen and water, making the AdBlue tank an integral part of the emissions control architecture rather than an optional addition.
