Part of one platform

One software stack

All four series share the same software core, so a vehicle platform can move up in power without starting again.

Tuned to your vehicle

Torque maps and regeneration strategy are set in firmware for each programme.

Built for India

Optimised for Indian drive cycles and rated for heat, dust and vibration.

Local engineering

Hardware, firmware and algorithms are our own, supported by engineers in India.
