What you'll learn:
- What is acceleration and top speed performance what limits it?
- What is Handling performance and what are the factors which contribute
- What is Braking performance and the Importance of ABS
- What is NVH and Ride vibrations, how are they dealt with
- What do you mean by vehicle durability and aspects related to structural strength
- What constitutes the factors affecting Fuel economy of an IC engine vehicle?
Automotive Design is driven by the targets set for performance. Understanding these performance metrics and characteristics is a very important part of the overall Vehicle design process.
This course aims to provide an idea of each of these specific areas of performance related to the Typical IC (internal combustion) engine Vehicle.

The course is designed to be Beginner friendly and consists of minimal Math with a "First Principles" approach.
If you are a student, engineer working in Automotive industry or an enthusiast wanting to learn about Automobiles this course will give you a Holistic understanding of Performance Criteria which matters and build a conceptual intuitive understanding of underlying principles.
This course doesn't deal in-depth in any of the area only deals with "what matters" .
This course may not be for you if you are looking for a highly analytical approach .
This course is suitable for you if already know some basics of cars but want to know the engineering connections in performance.
Knowledge compiled in the course is partly academic and partly related to my experiences and learning throughout my working stint at an Automotive manufacturer as a mechanical design engineer .
