Red Bull releases fascinating documentary on the history of pit stops

Here's how pit stops have changed since 1950.

Back in the early days of Formula 1, pit stops could take more than a minute and required mechanics to bang on a wheel nut with a hammer. In 2016, Williams tied the all-time record for the fastest four-tire pit stop at 1.92 seconds, matching Red Bull's incredible stop at the 2013 United States Grand Prix.

On Wednesday, Red Bull released a breathtaking 44-minute documentary exploring the history of pit stops, and it's a must-watch for Formula 1 fans. You can check out a trailer below, but you can stream the entire documentary online for free at Red Bull's website.
