In *Need for Speed Heat* (NFS Heat), muscle cars play a significant role in the game, offering a blend of raw power, aggressive styling, and a distinct driving experience. These cars are known for their heavy, powerful engines, typically with rear-wheel drive, making them ideal for straight-line speed but more challenging to handle in tight corners.

**Key Characteristics of Muscle Cars in NFS Heat:**

1. **High Torque and Power**: Muscle cars in NFS Heat often come with high torque, making them beasts in drag races or straight-line pursuits. Their powerful engines give them an edge in races that require quick acceleration.

2. **Customization**: Like other cars in the game, muscle cars can be extensively customized. Players can modify everything from the engine, exhaust, and turbo to visual upgrades like body kits, spoilers, and decals. This allows players to tune their muscle cars to either improve handling or further emphasize their raw power.

3. **Handling**: While muscle cars are powerful, their handling can be more challenging, especially at high speeds. They tend to be heavier and can have a propensity for oversteer, making them a bit tricky in sharp turns or drift events. Players often need to adjust their driving style or tune their car's suspension and tires to improve handling.
