Accurate information on the lengths of straights in Formula One is hard to come by, often with very different lengths from different websites and sources, so I have done my best to find the real lengths of the longest straights from reliable sources.

However, the longest straight EVER used in Formula One is none of these, nor is it the 1475m straight at the Fuji Speedway (though that is the longest in recent years). The longest is at the Pescara Circuit, used once in F1 back in 1957, also the longest ever lap in F1, a massive 25.579km long lap. There is no precise length of the straight as it was a long time ago, but it was around 6 to 6.5km long, around six times that of India!
You may have noticed I haven’t added the straight at the Circuit of The Americas in this, but at the moment I can’t find any information I trust, only that it’s apparently 1.2km, but some sites also say China, Korea and Abu Dhabi are all 1.2km and they’re not.
What about the Bahrain main straight. I did measure it, and I also heard about it, it is about 1,160-1,200 m !
Not sure, I haven’t seen any data on it, doesn’t seem that long though
