What Is 2017 24 Hours of Le Mans

Overview

The 2017 24 Hours of Le Mans was the 85th running of the endurance race and a key event in the 2016–17 FIA World Endurance Championship season. Held at the Circuit de la Sarthe in Le Mans, France, the race attracted global attention for its dramatic finish and intense manufacturer rivalry.

Competing in the LMP1 class, Porsche, Toyota, and Rebellion Racing fielded prototypes designed to endure 24 hours of continuous racing. The event drew over 260,000 spectators and millions more through live broadcasts, highlighting its status as one of motorsport’s most prestigious events.

• June 17–18, 2017: The race began at 3:00 PM local time and concluded 24 hours later, following the traditional midday start format used since 1923.
• Porsche #2 victory: The winning car completed 388 laps, covering approximately 5,000 kilometers, marking Porsche’s 19th Le Mans win in history.
• Toyota’s heartbreak: The #7 Toyota TS050 Hybrid led for over 23.5 hours before retiring due to a sudden engine failure with just under 10 minutes remaining.
• Manufacturer competition: Porsche and Toyota were the only factory-backed LMP1 teams remaining after Audi’s 2016 exit, intensifying the rivalry.
• Driver lineup: The winning trio—Earl Bamber, Timo Bernhard, and Brendon Hartley—combined experience and precision to manage tire wear and fuel strategy over the full duration.

How It Works

The 24 Hours of Le Mans is an endurance race where teams of three drivers share a single car over a 24-hour period, aiming to complete the most laps. Success depends on reliability, fuel efficiency, pit strategy, and driver stamina.

• LMP1 Class: The top prototype category featured hybrid powertrains. In 2017, only Porsche and Toyota competed at this level, with cars producing over 1,000 horsepower.
• Hybrid Systems: Both Porsche and Toyota used kinetic energy recovery systems (KERS) to boost acceleration, with 6 MJ of energy per lap allowed under FIA regulations.
• Driver Rotations: Each driver typically spends stints of 1.5 to 2 hours behind the wheel, with mandatory rest periods between shifts.
• Pit Stops: Teams conduct refueling, tire changes, and minor repairs every 45–60 minutes, aiming for minimal downtime.
• Full Course Yellow: When incidents occur, a safety car period is initiated, reducing speed and freezing positions for 5–20 minutes until cleared.
• Headlights & Night Driving: The race runs through the night, requiring functional headlights and visibility management, with 6 hours of darkness during the event.
