What Is 2018 24 Hours of Daytona

Overview

The 2018 24 Hours of Daytona, officially known as the Rolex 24 at Daytona, was a premier endurance sports car race that kicked off the 2018 IMSA WeatherTech SportsCar Championship season. Held at the 3.56-mile Daytona International Speedway road course in Daytona Beach, Florida, the event attracted top manufacturers, professional drivers, and international teams.

As a 24-hour endurance race, it tested teams' mechanical reliability, driver stamina, and strategic execution under pressure. The race featured multiple classes of vehicles competing simultaneously, with the overall winner determined by the greatest distance covered in 24 hours.

• Start Time: The race began at 2:40 PM Eastern Standard Time on January 28, 2018, under overcast skies with mild temperatures.
• Track Length: The Daytona International Speedway road course spans 3.56 miles and includes 12 turns, combining the oval and infield sections.
• Entry Count: A total of 41 cars were entered across four classes: DPi, GTLM, GTD, and Prototype Challenge (PC).
• Winner: The #5 Mustang Sampling Racing Cadillac DPi-V.R, driven by Filipe Albuquerque, João Barbosa, and Christian Fittipaldi, completed 725 laps to win overall.
• Historic Note: This was the 56th running of the Rolex 24 at Daytona, one of the most prestigious endurance races in North America.

How It Works

The 24 Hours of Daytona is structured around endurance racing principles, where teams of drivers rotate behind the wheel across a full day and night to maximize distance covered. The race tests not only speed but also mechanical durability, pit efficiency, and driver adaptability to changing conditions.

• Endurance Format: The race runs for 24 consecutive hours, requiring teams to manage fuel, tires, and driver changes without stopping the clock.
• Driver Rotations: Each car has a team of 3 to 5 drivers, with mandatory minimum drive times and maximum stints regulated by IMSA rules.
• Refueling Strategy: Pit stops for refueling occur every 45 to 60 minutes, depending on fuel capacity and engine consumption rates.
• Class Competition: Cars compete in four classes—DPi, GTLM, GTD, and PC—with separate championships awarded per class.
• Scoring System: The overall winner is the car that completes the most laps in 24 hours, regardless of class.
• Safety Protocols: The race features full-course cautions and safety cars to manage incidents, with strict night-driving regulations for visibility.
