Tata Motors reported a three-fold spike in group net at Rs 2,502 crore for the September quarter, driven by a one-time excise gain of around Rs 535 crore, cost-reductions at the planning and strategic levels and better margins and volumes at its British arm JLR.
However, on a standalone basis Tata Motors still remained in the red but with hugely narrowed losses.
