Key facts

  • Punch EV Rs 9.7L to Rs 6.5L
  • Creta Electric Rs 18L to Rs 11L
  • BaaS Rs 2.3-5/km
  • eC3X min 2,000 km/month Rs 4,520
  • e Vitara min 1,800 km Rs 7,200/month
  • MG BaaS 12-15% of EV sales

Why this matters

With Tata, Hyundai, Maruti, Citroen and MG all launching BaaS, battery leasing platforms and per-km billing infrastructure become strategic acquisition or partnership targets to capture the emerging recurring-revenue layer of EV retail.

What to watch

  • First wave of high-mileage BaaS owners reporting cost overruns (12-18mo out)
  • Regulatory action on TCO disclosure or usage-clause caps
  • Battery cell price declines that erode BaaS upfront-discount rationale
  • Resale/second-owner friction on BaaS-locked vehicles
  • Competitor pricing response and any BaaS fee revisions
  • Publish transparent TCO comparison tools showing BaaS vs. outright ownership break-even km
  • Introduce flexible per-km tiers and buyout options to defuse min-usage lock-in criticism
  • Bundle battery warranty/health guarantees to justify recurring fees
  • Segment BaaS marketing toward low-mileage urban commuters where economics favor it
  • Competitors without BaaS to push 'no hidden per-km fee' messaging as differentiator
