I was there at the Bharat Expo 2024 and will let the pictures do most of the talking. The auto expo and the parts expo were together and there was a separate registration process for the parts expo. Spread across the entire pragati maidan, the expo was really large and had something of interest for everyone.
Key observations - The entire ecosystem - cars, two wheelers, three wheelers, buses, trucks, parts, ancillaries, tyre manufacturer - was present. There were stalls for car care products too. All technologies and fuels showcased - fossil fuel, electric, hybrid, hydrogen, flex fuel. Side events like road safety and go karting were also there. India and foreign both players were equally present. Some of the stalls were really B-I-G and lot of space to move around and get the feel of the vehicles.
Compared to previous years, it was very well organized, well spread out, well managed and weather also supported the event with nice bright sunshine on a cold day.
