What strategies do F1 drivers use to optimize fuel efficiency during a race?
Quick fact
F1 drivers lose up to 5 kg (11 lbs) of fluid per race due to cockpit temperatures exceeding 50°C (122°F) and wearing a fireproof suit.
Why this is interesting
After a 90-minute Grand Prix, a driver can weigh 4–5 kilograms less than when they started—all from sweating.
