Tata Nexon EV used to have a monopoly in the Indian EV space until recently Mahindra introduced XUV400 EV. The specifications and pricing made it the closest and strongest rival to the Tata EV. Here is a A/B comparison.
XUV 400 Power : 150 PS Torque : 310 Nm Battery Pack : 39.4 kWh
Nexon EV Max Power : 143 PS Torque : 250 Nm Battery Pack : 40.5 kWh
XUV 400 Range : 456 km 0-100 kmp : 8.3 s Regen : 3 level adjustable
XUV 400 Drive modes : 3 (fun, fast and fearless) Boot space : 368L
Nexon EV Max Drive modes : 3 (eco, city and sports) Boot space : 350L
XUV 400 AC charger : 3.3 kW & 7.2 kW AC charging speed : 13 hours from 16A AC socket
Nexon EV Max AC charger : 3.3 kW & 7.2 kW AC charging speed : 10-100% in 15 hours from 15A AC socket
Nexon EV uses LFP cells whereas Mahindra XUV 400's battery pack uses NMC chemistry. NMC can deliver more outright performance and faster charging times, but is older gen chemistry. LFP on the other hand, are more advanced, stable, durable and safe. There is a slight trade-off in performance & charging speed for more number of charge-discharge cycles and better reliability
The XUV 400 is priced from Rs. 15.99 lakh to Rs. 18.99 lakh (ex-showroom) 3 variants are available. Nexon EV is priced from Rs. 14.49 Lakh for the prime and from 16.49 lakh for the Max. 6 variants are available on Nexon Max.
