The Racing Line: The Only Line You Need! – The Racing Line Ep. 4

it’s the fastest way around the track
and also happens to be the name of the show yes you guessed it on this episode the racing line we’re talking about
the racing line every corner on earth has three ideal
placement points targets at which to aim your car the beginning of a corner is called
the turn in next we have the holy grail of the racing line the almighty Apax and finally exiting the corner we’ve got the track out proper racing line should look
something like this start at the turn in come down to the apax and
continue to the track out outside to the inside of the pavement back to outside
simple enough for racing line really the fastest way around the corner well lets get in our track capable Cadillac ATS and find out first I’m gonna take the inside
line the shortest route then I’m gonna take the outside line the longest route next I’ll
take the racing line to see which one is the fastest ready here we go the inside line
now the inside route around a corner is the shortest way but is it the fastest the outside line the outside route is the
longest way around the corner which allows for greater speed than the
inside route racing line now for the racing line it’s the best of both worlds outside inside outside using all
available payment to make the corner as wide as possible as you can see from the
results the racing line is much faster than the other two routes that allows
you to carry more speed into the corner maintain a high speed throughout and
edged higher velocity but why is that it’s simple the larger the radius and
more speed can be carried through the corner now I’m driving a small diameter
circle right at the limit of grip and I’m able to maintain twenty miles per
hour now I’m driving a wider circle again right on
the limit of grip and I’m able to go thirty miles an hour now I’m drifting because it’s more fun and that’s what your doing when driving the racing line more radius equals
more speed equals less lap time it’s simple geometry speaking of simple
geometry let’s look at how tires relate to the racing line on today’s
Tire Rack minute you can get the most from your tires by isolating their
functions and not overloading them and you’re racing line is the key sometimes later and races tires start
feeling greasy isolate your loads more to save them cornering loads distort the side walls
in contact patch and cause them to easily slide too much so use a late apex
to straighten breaking accelerations zones to capitalize on the
better grip under vertical loads when the contact patch is less tortured what
I’m trying to say is tires need love too big good to them so what we’ve been
looking at so far are constant radius turns now let’s look at some other
corners around the track to see how the racing line varies help in this is a
hairpin it’s a slow corner and the fastest way around a slow corner believe
it or not is slow cars turn better when slowing because it puts more load on the
front tires be patient wait on the gas and get to the inside and apex late in
the corner this will straighten your line to the track out allowing better
acceleration and higher speeds going on to the straight increasing radius this is
an increasing radius corner it’s the most forgiving of corners it starts tight
then opens up these corners allow you to get on the power early as you pour on
the coals with plenty of room to slide wide there are lots of fun decreasing radius and this is a large
decreasing radius corner it tightens up on you as you go through this most
difficult and dangerous corner on a racetrack planning ahead pays dividends
here enter with lots of speed but think ahead
and inside apex very late in the corner wait for the road to start
opening up before squeezing on drugs or you’ll end up doing agricultural work
off the road so far we’ve been looking at the ideal line in a perfect world but there are
some times when you need to adjust it for maximum speed corner with bump
take this corner for example from the apex on the track out it’s very bumpy
on the normal racing line so I take a later Apax a tighter exit to avoid the
bumps and get the power down off-camber corner and in this corner the road is crowned on the exit going off camber so again I apex late to
straighten the exit and keep from sliding off the racing line we didn’t name is show
after it for nothing you know it can make the difference between being a
winner and being a sorry loser chump and on that note Apax responsibly driving
enthusiasts I will see you next time on the racing line when I was a kid I
started in all across and I drove flat out like a raving maniac is good on the
very first he would tell me with more experience Randy slowdown you go faster
but they’re crazy arms beating that what do they know until one event I tried to
go slower on purpose and I want to check the time it was faster in the region was
I was using the racing line I didn’t understand it before

  1. How stupid and simple minded do they think we are? This is so basic they may as well give instructions on how to start a car. Ugh

  2. wonder if there will ever be a HUD that will show the racer the best racing line? I heard something about 2 years ago that someone was working on putting HUD in motorcycle racer's helmets that would show the track, where they are on the track, and where everyone else is.

  3. Anybody know what the song is that they use when he's talking (usually used throughout the videos)? The one with the whistling?

  4. I only have one question for Randy…
    How many takes did the first corner demonstation take? I guess you really had to work hard to keep your racing instinct in check when driving the full inside and outside line demonstration 😛

  5. I'm glad I found this channel. I just like listening to Randy 🙂 . What track are you guys running? I'm guessing in Cali, somewhere. It doesn't look like Chuckwalla or Willow Springs, and I know it isn't Buttonwillow….

  6. I am very intrested to see how you can use the handbrake (e-brake for some) in mid corner to go turn faster. I saw Keiichi Tsuchiya doing it in a fwd honda!
    If anyone is intrested video title is
    [ENG CC] Spirits Integra R vs. Nissan GT-R R34 vs. K-Shift CR-X HV45 at 5:05

  7. With plenty of horsepower and braking capacity; have some racers found it to be quick – to race to the corner, brake hard and blast it out?

  8. Whilst it may be true that racing lines are more relevant than ever, in this day and age, I feel that reading in-between the lines to be far more fruitful and practical

  9. Shit…. He would be much more greater as the new TopGear presenter…. I feel sick when I hear Evans.

  10. after years of GT and Forza, I finally understand the point of why the racing line is the way it is. Thank you. Great series

  11. A bit late but these are great and very informative videos.

    5:25 had me laughing so hard with the over the top consequence! Thanks Motor Trend and Randy.

  12. video >9000 <^.^>

    This video has everything. ATS-V, Randy Pobst, math, physics, humor, infographics, cinematography and editing wizardy, no shitty music, whatever else, and did I mention Randy Pobst driving a badass Cadillac? 🙂

    But wait, there's more:
    3:42 Is this a "videoinfographic"?

  13. 2:37 velocity is straight like displacement so velocity equals zero on a circular track every time you pass the place you started

  14. Funny thing – I don't know how it is in other countries but in this one, cornering outside to inside to outside is a normal thing tought to drivers in driving ed (within one lane of course). Maybe there's something to it outside of racing too after all.

  15. Dude its obvious! Why the heck would they call it “the racing line” if it wasn’t fast! 🤦‍♂️

  16. i hate decreasing radius corners
    like the first on suzuka oder the last on monza and tsukuba
    you roll around thinking everthing is fine and then you just get carried off the track

  17. Noooo. There are some faster lines that you can take. Coke / amphetamine / mdma. Easilly faster than that. Try it, you will see.

  18. Remember, during the day on a mountain road, the double yellow IS the apex. During the night however, apex is the apex
