How are engines mounted in a vehicle and why?

Answer 1

Engines are mounted to the car using bolts to secure the engine to a set of special mounts.

The mounts are made of different materials (Usually steel and rubber bonded together) to keep the noise and vibration down, yet built so the engine is securely fastened to the car.

Engines are mounted in the front, middle or rear of the car.

They are also mounted transversely or longitudinally ( Crosswise or front to back )

These different combinations produce weight distribution differences and allow designers to make interiors and bodies more ideal from styling and purpose considerations.

A small car with a mid engine transversely mounted allows for a small nimble well balanced sports car. ( The Toyota MR2 is a good example )

A longitudinally mounted engine of large displacement mounted over the front wheels is an almost ideal situation for a large commercial van or pick up truck.

I think if you look at any car on the street you will see what the designer was trying to accomplish with how the engine is mounted.
