Engines may be placed in three main positions within the car:
- front engine mounted - the engine is mounted under the hood, over the front axle
- rear engine mounted - the engine is mounted where the trunk would normally be, over the rear axle
- mid engine mounted - the engine is mounted between the front and rear axles, where the rear seats would be located
