The Heart of a Champion: Engine Specifications
Modern Daytona 500 engines are highly regulated, pushing engineers to find every possible advantage within the rules.
- Engine Type: Naturally Aspirated V8
- Displacement: 358 cubic inches (5.86 liters)
- Horsepower: Approximately 650-700 hp (before restrictor plates)
- Torque: Around 500 lb-ft

Restrictor Plates: Balancing Power and Safety
Restrictor plates are a crucial part of Daytona 500 safety, limiting airflow to the engine and reducing top speeds.
Restrictor plates are metal plates placed between the air intake and the engine. They reduce the amount of air entering the engine, which in turn reduces horsepower and speed. This is done to keep the cars grouped closer together and reduce the chance of catastrophic crashes at Daytona’s high speeds.
Impact on Performance
The use of restrictor plates dramatically changes the driving style and strategy at Daytona.
Fact: Without restrictor plates, Daytona 500 cars could potentially reach speeds exceeding 230 mph.
