1. About Virtual BAJA

The Virtual BAJA SAEINDIA is a filtration criterion, through which all the registered teams are scrutinized for their knowledge and capability to participate successfully in the main event. Virtual BAJA started in the year 2009 and is supported by working professionals as judges and volunteers across the country.

The Virtual BAJA SAEINDIA acts as a pre‐qualifier to participation in the BAJA SAEINDIA event.

The objectives of the Virtual BAJA event are as follows:

1. To acquaint the teams completely with the objectives of the BAJA SAEINDIA event.

2. The teams are required to familiarize themselves with the technical guidelines and limits for the design of the BAJA vehicle.

3. To design the complete CAD Model of the BAJA Vehicle. The design should be complete in all respects to the extent of being considered ready‐to‐manufacturing.


Based on the performance in the Virtual BAJA, the teams would be selected for participation in the main event.

- Any content about SAE Collegiate Club or past activities

- Any CAD / CAE videos are not allowed. Instead, teams should present the data in the form of mathematical or meaningful data. For E.g.: boundary conditions Crash test analysis values, present deformation value, g‐ values, FOS, etc.

- Any content that tries to influence the judging panel for favourable consideration of team in the selection process

- No report or other documents are to be submitted before or during Virtual BAJA SAEINDIA 2019.
