Estimate the number of cars sold in India in 2023

Estimate the total number of new passenger vehicles (cars, SUVs, sedans, hatchbacks) sold in India in the year 2023.

Context

India recently surpassed Japan to become the 3rd largest automotive market in the world behind China and the US.

Clarifying questions to ask first

• Are we including commercial transport vehicles (taxis/trucks) or passenger cars only? (Passenger vehicles).
• Are we counting new car registrations or used car transactions? (New car retail sales).

How to approach it

1. Demand-side: Population (1.4B) -> Middle/Upper class car-buying households (~60-70M) -> Annual purchase/replacement rate (~6-7%)
2. Supply-side: Top Automakers market share (Maruti ~42%, Hyundai/Kia ~21%, Tata Motors ~14%, Mahindra ~10%, Others ~13%)
3. Segment by Body Type: Entry Hatchbacks (28%), Compact/Mid-size SUVs (50%), Sedans (12%), Luxury/EV (10%)
4. Cross-check against known industry milestone (~4.1 Million units)

Framework: Total Annual Car Sales = (Car-Buying Household Base × Annual Purchase Rate) OR Sum of (OEM Production Capacities)

Sample answer

• Automaker Capacity Approach: Maruti Suzuki sells ~1.7M cars/year (~42% share)
• Total Market = 1.7M / 0.42 = ~4.05 Million passenger cars
• Household Demand Approach: 65M upper-middle class homes × 6.5% annual buy/upgrade cycle = ~4.2M cars

1. Supply calculation: Maruti (1.7M) + Hyundai/Kia (0.85M) + Tata (0.55M) + Mahindra (0.45M) + Toyota/Others (0.55M) = ~4.1 Million cars

Executive estimate: ~4.1 Million passenger cars sold in India in 2023 (~$50B revenue; SUVs representing ~50% of all sales).
