The Sierra EV runs purely on electricity with 63 kWh and 75 kWh LFP packs. Single-motor rear-drive versions deliver claimed MIDC ranges of 565 km and 665 km. The dual-motor AWD version is rated at 624 km. Real-world figures are quoted around 440-460 km for the smaller pack and 510-530 km for the larger one. DC fast charging at up to 120 kW can add around 263 km in 15 minutes or take the battery from 20 to 80 percent in about 26 minutes. V2L and V2V power sharing are available.
Servicing follows a 10,000 km or one-year interval, whichever comes first. Visits cover multi-point checks, brake fluid, battery coolant, cabin filter, software updates and the 12 V battery. There is no engine oil or many traditional wear items. Brake pads last longer thanks to regenerative braking. Tyres see more wear due to the vehicle weight. Lifetime high-voltage battery cover applies for the first private owner for 15 years with unlimited kilometres, dropping to 10 years or 200,000 km for subsequent owners.
Six airbags, ABS with EBD, electronic stability control, electronic parking brake with auto-hold and ISOFIX anchors come as standard across the range. Higher grades add TPMS, 540-degree camera with transparent underbody view, blind-spot monitoring and Level 2+ ADAS with 22 functions. The petrol-diesel Sierra earned a full five-star Bharat NCAP rating with strong adult and child scores. The EV has not been crash-tested separately but shares the same platform structure.
Daily ownership centres on the battery warranty and longer service gaps. Keep records of authorised services and follow charging guidelines to protect cover. The car includes connected features for remote monitoring and OTA updates. A puncture repair kit replaces the spare wheel. Ground clearance stays at 205 mm.
