Pushing Your Weight Around, Weight Management! or Heavy Tires! – The Racing Line Ep. 11


– My job as a race car driver is not as unique as you might think. There’s one occupation that
offers a striking resemblance. What is that? A sumo wrestler! (thundering) (swords piercing) I know what you’re thinking. What can a race car driver possibly have in common with a sumo wrestler? (smacking) We’re both experts in weight management. And that’s what we’re
talking about today on The Racing Line. (rock and roll music) Now most of you are probably thinking I’m crazy for comparing my skinny self to a sumo wrestler. I know, I know, the two careers could
not be more different. But hear me out. My job as a race car
driver is to win the race. A sumo wrestler’s job is to win the about. And how do we do that? (slamming) (slurping) Weight management. (burping) It’s my job to manage
the weight of the car for the fastest lap time. And it’s Beyama’s job to
eat 4,000 calories a day to maintain his physique. Now that you see what I’m gettin’ at, let’s get started. Not too long ago,
driver’s ed used to teach everyone about weight management. In particular, when you
encountered a deer on the road. (brakes screeching)
(screaming) What were you told to do? Hit the brakes, right? (metal crashing) No, because that would transfer weight to the front of the car
(screaming) and drop the nose
(squelching) increasing your chances of getting injured by creating a deer ramp
(screaming) into the car. Instead, they told you to hit the gas. (squelching) Hitting the gas would transfer weight to the rear of the car raising the nose and allowing you to effortlessly drive over the deer (squealing)
rather than join you inside the car. (yelling) In modern times, suspensions have become
far more sophisticated. More focus has been put on
safety through better handling. Because of this, cars
don’t pitch, roll, and dive like they used to. They stay relatively level and flat. You can no longer (brakes squealing)
see the weight transfer like you could in the good old days. For demonstration purposes, we’ve had to bring in
a much taller vehicle with more suspension travel so you can better see the
weight being transferred around. Now before I show you what
weight transfer looks like, let me show you where
it gets transferred to in the Tire Rack Minute. The only part of the car
that touches the ground is the bottom of the tire, the contact patch. As you can see, there’s
not a lot of rubber actually touching the pavement. Multiply this by four, and that’s the only thing
keeping you attached to the road. That’s why it’s important to
transfer load to the tires that need the grip. The more weight, or
load, you put on a tire, the better it sticks. Try this right now. Lightly brush your fingers
across whatever you have in front of you. Now do it again but push harder. (squeaking) What happens? Your finger sticks because
you’ve added more load to it. More load, more grip. Now, to demonstrate
weight transfer on track, we’re going to employ the
help of our sumo wrestler (gong ringing)
stunt double. Let’s do a lap on the track.
(door slamming) Now watch, wherever the balls go, that’s where the load is. Okay, we’re racing down the straightaway driving nice and straight and level, not transferring much weight, adding more speed. Heading for turn one where
we’re going to dive into this like now! (tires squealing) Okay! Little rough back there, hey buddy? Turning left, the load and the weight
transfers to the right. Turning to the right, the weigh and load transfers to the left. Shoot, this van handles great! (laughing) What do you think about weight transfer, mister sumo wrestler stunt double? (banging) Oh, that was a big one. Down the front straightaway we go. Accelerating sends
weight towards the back. Braking, weight moves forward. (crashing) Oh, it’s mayhem. Oh, the humanity, or the mannequinanity. Now let’s break it down at a slower pace. Coming into the corner, brake hard and straight. The load is now transferred
to the front tires. As you turn in, release the brake slowly and trail brake using that load to help steer the car. Then as soon as you know
you will make the apex, ease onto the gas, transferring to load to the
rear wheels for traction, and open the throttle as
you straighten the wheel, and rock it out of the turn. This is fastest way to
get around a corner. (Japanese koto music) (thundering) (tires squealing) So whether you’re a sumo
wrestler or a race car driver, learn to manage your weight. And should you encounter a deer, hit those brakes and use
those loaded front tires to steer safely around him. And on that note, transfer your weight
wisely, driving enthusiasts, and we’ll see you next time on The Racing Line. if you like watching the racing line here’s a teaser for the next episode live right now on Motor Trend On Demand (cars zooming) I’ll come to grips with the fact that I middle-aged veteran if you will ok so after 500 road races I’m a veteran but you’re never too old to learn something new so today I’ll be tackling a new racing line in a truck wait you really want me to drive a truck I don’t do trucks or do I they are kind of badass on second thought Lets drive some trucks Yee haw watch the latest episode of the Racing Line right now on Motor Trend On Demand

  1. I love this guy! when did he get some charismatic on camera? Not that he was bad before, he just owns the crap out of his character now! Love it!

  2. I was just thinking… Randy is a vegetarian, but judging from his voice, he's probably smoking those vegetables instead of eating them.

  3. Oh and forget the idiots&trolls livin in their momma's basement…u just keep doin what ur doin. And kick that mts ass in june. Thats an order soldier!!!!!

  5. oh deer, no srsly what's the matter with this series? The toppics make sense and I think a lot of people really learn something but it's pushed into this kids cartoon thing, is this just it's style or is it really a kids show? I really don't know.

  6. I'm pretty sure he eats more than 4,000 calories a day cuz some athletes and body builders eat triple that granted he's not doing intense excercise but just moving his body around and Tryna wrestle 500 pound men is a workout in itself

  7. Randy…I don't know if you notice but your walking is off. I'm not sure if it is because of your sitting/driving or because of your pedals/clutch/brake too much but please take great care of yourself. Don't want to lose such a great narrator for such an awesome series 🙂

  8. I love how this guys makes funny scenes, funny associations and jokes algong the video. Not only makes it easier to understand, but also it prevents the video from being boring to someone who doesn't work with cars making he/she lose interest. Now I see why this channel is so popular.

  9. I was told way back that when you turn into the corner it is not you (the crash dummy in this case) that moves but the car, you keep travelling forward but the car moves either to the left for the right, same thing with accelerating or breaking hard.

  10. Best and as far as i'm concerned, only show on Motor Trend worth watching. H2H sucks anymore, trying to do more "gimmick" than review.

  11. I just want to say a big thank you to you guys for this video. I had to significantly downsize my car a year ago, as my old truck was no longer road legal and all I could afford to buy way a nasty little 2004 Suzuki Alto (front wheel drive microcar with a 67 cubic inch inline four, don't think it made it to the US).

    After getting the thing if was fine for a little while but as I got used to it I was finding it was a bit unstable in bends. Then, one wet night in fall, the thing went sideways half way around a roundabout (traffic circle) at 20 miles an hour. TWENTY! The speed limit on this roundabout is 40. And then it happened again a couple of weeks later at maybe 15mph on a smaller roundabout. I got new tyres, that helped but didn't solve the problem, spun with those on too. Winter happened, though it wasn't very snowy here, then spring and summer were pretty dry.

    Then I saw this video a few weeks ago. After watching it a couple of times and having a bit of a think about it, I made a few changes to the way I drive and good god did it make a huge difference. The car may still be a tiny, cramped little P.O.S. but at least it feels like the rear end is actually touching the road now. It feels so much more stable in curves. I know these tips are intended for high speed driving but in crappy cars they can clearly make a huge difference at road speeds. My car may be garbage but at least I feel safe driving it now.

    Once again, big thank you guys.

  12. And Accelerating towards the deer works great if your car is made of good ol American steel, not the plastic crapboxes made today

  13. 4:50 You can see the Sumo wrestler's feet disappear under the front bumper right as the van pulls up. It was done in two different shots.

  14. It's a common misconception that the area of contact changes the force of friction, but this is incorrect. The small patch of tire contacting the road generates the same amount of frictional force as would a larger tank tread. This is because the force of static friction is equal to the coefficient of static friction times the normal force. Nowhere in that equation is anything to do with the area of contact.

  15. Uncle Jasper use to go out nights on them mountain roads, depending on that front / back weight transfer.
    Old, huge work truck with a nice, heavy front guard. Handled more like a boat than a car.
    You don't steer, you make course corrections. 😉 Massive nose lift / dive with sudden throttle actuation.
    See a deer in the road, high beams go on, and hit the gas! Food for the family for a week.
    (make sure one of your family is a good butcher, you ain't taking that venison to town.)

    Awesome info as always. And yah, it sure ain't like it was in them ol' days. 😉

  16. I dont brake or swerve for deer. If you hit them it instills it in the others that seen it to stay away. It's when people stop, slow down or swerve for them that it teaches them that we are afraid of them. Not my truck with a push bar. 4 deer and counting
