The MG Hector Tomahawk PHEV is India's first mainstream three-row plug-in hybrid: a 1.5L petrol engine plus a 20.5 kWh battery for 303 PS combined, 115 km of electric-only running and a claimed 1,100 km total range. At ₹25.70–27.80 lakh it costs SUV-flagship money, but for daily commutes it can run as a pure EV and still road-trip without charging anxiety.
