What are the key differences between front-wheel drive (FWD), rear-wheel drive (RWD), and all-wheel drive (AWD) vehicle configurations, and what are their advantages and disadvantages

Front-Wheel Drive (FWD):

1. Configuration: In FWD vehicles, the engine's power is transferred to the front wheels, which also handle steering.
2. Advantages:
   • Better traction in inclement weather conditions like snow and rain, as the weight of the engine is over the drive wheels.
   • Typically more fuel-efficient because of lighter weight and simpler construction.
   • Better space utilization in the vehicle's cabin since there's no need for a driveshaft running to the rear wheels.
3. Disadvantages:
   • Less balanced handling, as all the power is directed to the front wheels, leading to understeer in high-performance situations.
   • Can struggle with excessive torque steer, where power delivery causes the vehicle to pull to one side during acceleration.

Rear-Wheel Drive (RWD):

1. Configuration: RWD vehicles transfer power from the engine to the rear wheels. The front wheels handle steering only.
2. Advantages:
   • Balanced handling dynamics, with more even weight distribution between the front and rear wheels.
   • Ideal for performance-oriented driving, as it allows for better weight transfer during acceleration and braking.
   • Generally preferred for towing and hauling heavy loads due to better weight distribution.
3. Disadvantages:
   • Potentially poorer traction in slippery conditions since the weight distribution shifts towards the rear, reducing grip on the drive wheels.
   • Historically, RWD vehicles have been less fuel-efficient compared to FWD counterparts, although modern designs have narrowed this gap.

All-Wheel Drive (AWD):

1. Configuration: AWD vehicles use a system that delivers power to all four wheels either full-time or automatically when needed.
2. Advantages:
   • Improved traction and stability in various driving conditions, especially on slippery surfaces like snow, ice, and mud.
   • Enhanced performance capabilities, especially in off-road or high-performance situations, as power can be distributed to wheels with the most grip.
   • Increased safety by reducing the likelihood of wheel slippage and loss of control.
3. Disadvantages:
   • Generally more complex and expensive to manufacture and maintain compared to FWD or RWD systems.
   • AWD systems often add weight to the vehicle, which can negatively affect fuel efficiency.
   • Some AWD systems may exhibit understeer or oversteer characteristics depending on their design, potentially affecting handling dynamics
