The One Design Change That Made NASCAR Races Faster

NASCAR is famous for speed — and that speed wouldn't be possible if not for the banked turns of NASCAR’s tracks. Banked turns, the parts of the track where the road slopes inward, keep NASCAR drivers safe and driving at faster, more exhilarating speeds. Here’s how NASCAR’s banked turns work.

The One Design Change That Made NASCAR Races Faster

[SupremeLeaderKimJong-un]

Lightning McQueen is the greatest race car of all time

[ChrisInvests]

If you ever see a track you'll be amazed at how steep it really is 😮👍

I feel like the explanation at 3:30 was quite vague.

The force of the car due to gravity is going straight down, however, the banked curve directs part of the force to the direction of the turn. If you were somehow driving on a perfectly vertical wall, you wouldn't need to worry about turning considering all the stress is being taken off the wheels.

I'm going to the 2020 Daytona 500, so I'm gonna get to see these Daytona banks with my own 2 eyes.

[HPayne]

I went to the Daytona 500 this year and during a caution, one of the cleaning trucks that was cleaning up oil cleaner broke down and actually SLID DOWN THE BANKING.

3:58 why tf they’re using a video of Paul ricard???

[Bigpimpdaddy]

“Daytona was unlike any racetrack before it” I guess Monza doesn’t exist

[cav]

I love how at 4:10 he’s talking about Talladega but they’re showing AutoClub speedway and just before that they were showing Paul Ricard in France lmao

[xavierd]

“Talleadega super speed way “ shows auto club

[christophermichael]

U don’t compare Daytona and Martinsville for bankings!

U use Bristols for that!

[AverytheCubanAmerican]

I remember watching Nascar with my dad and collecting the toy cars....Nascar's heyday is long gone

[NRF]

I want to the 2019 Daytona 500 earlier this year and it was pretty cool seeing those cars fly past me with my own eyes at over 200 miles per hour. I actually got to walk on the racetrack and almost fell down when I was trying to walk up the entrance to turn one.

[mesumnaqvi]

I would love to see a new circuit featuring a turn based on the Daytona banks in F1!

[Joopyter]

Short version
when you turn in a car you get pushed outwards
So put a bank and it pushes you into the bank
So you get more grip
Thats why it can go faster on a banked corner than a flat one

Nascar Cars: *I am speed.*

[Kinamod]

Bit of a half explanation in this video...
They skipped that centruFUGAL force also adds to the equal and opposite reaction from the track, meaning the cars can get more than one G through the track to use on additional friction to turn.
Also, a banked track literally straightens out the curve. So you don't have to turn the wheels as much to make the same amount of change in direction.

[aslatabistaalphonso]

Fernando Alonso did a qualifying lap here.

[chwarac]

not just momentum, you forgot about the drag created from each car, and how they use it to slow the other car down, thats what makes the biggest difference to have speed to overtake

[cooker-otk]

Well doesn’t nascar also do road course races?

I might not have all the tracks but here’s a few

Trucks:
Canadian Tire Motorsports Park

Xfinity:
-Watkins Glen
-Roval
-Road America
-Mid Ohio

Cup
-Roval
-Sonoma
-Watkins Glen

Therefore, nascar doesn’t always go to the left. Each series heads to 6 different types of road courses, so it’s not always ovals.

Also how about INDYCAR. Are we really not gonna mention how many oval races they do as well or no?

[potatosordfighter]

Your explanation is missing another important factor of banks. The steeper the bank gradient, the straighter you actually go through the corner, and the less you have to turn. If a turn went to a full 90 degree bank, you would be driving in a straight line on a wall.
