Difficulty: 0

- Right, so rally racing,

arguably the craziest motorsport event

that one could be a part of.

You've seen the videos, I've seen the videos,

these drivers are just not human.

When it comes to the sport of rally racing,

not only does it take absolutely massive cojones,

but it takes a car that is capable

of taking the absolute beating

that they will see on the rally course.

What is goin' on, everybody, Gels from Fitment Industries,

and today, on this episode of The Build Sheet,

we're gonna take a quick dive into the crazy truth

about rally cars, how they are built,

and how they are able to handle everything

that their drivers throw at them.

Before we get right into it, wheels, tires, suspension,, you know, like the whole thing,

and we are still in the middle of doing the giveaway

with Konig wheels for the month of July,

so pick up a T-shirt, this T-shirt right here,

I'll show the back,

(engine screaming) Drift Mode, it's a Supra.

It's a buncha cool stuff.

Month of July, pick up a T-shirt,

easiest way to get entered in to win.

You can check the description,

All right, so originally what started as a race

between a few Frenchmen who were competing head-to-head

in a 127-kilometer race from Paris to Rouen

eventually set a pace for the A to B-style race

that we now know today as rally racing,

eventually evolving into the Monte Carlo Rally

that started in 1911, and all the way up to the 1980s,

in the now-called World Rally Championship,

when all-wheel drive took over, and Audi was the king.

They were out there

just slaying everybody with their Quattro,

and everyone else was sittin' on the sides, like, "(bleep),

"I guess we need to make our cars all-wheel drive."

And they did, and it launched a new wave of rally racing.

As Group B was in their golden age,

we saw cars like the Lancia Delta S4, and the 037,

and the Ford RS200, and even Porsches

bombing through rally courses.

As Group B came and went,

and eventually leading into the 90s,

and up to where we are today,

with turbocharged, all-wheel drive,

fire-breathing hot hatches.

Today, we see drivers competing in cars

such as the Ford Fiesta, Toyota Yaris,

the Hyundai i20, and a Citroen C3,

and now you're like Gels' brother.

A Toyota Yaris?

What is a Toyota Yaris going to do?

And I'm just gonna have Dakota

throw in some quick clips here, just real quick,

just check it out.

(rhythmic digital music) (engine screaming)

Isn't that (bleep) nuts?

I don't know about you, but I (bleep) love

every bit of that.

Anyway, now obviously, these cars

are nowhere near where they were

when they came off the assembly line.

So what is involved in taking

that little unsuspecting Toyota Yaris

and turning it into an absolute monster?

Well, let's go ahead and take a little look

into what is all needed.

So, first thing's first,

these cars are completely stripped down

and gutted right down to their bare bones.

Usually, they have custom panels made

to make them wider so they fit everything,

they get a massive roll cage,

a bunch of expensive racing gear on the inside,

and are converted to all-wheel drive,

but that's not really news to you,

you probably already knew that.

Like, it's a rally car, obviously,

that's pretty common sense,

but we're gonna be going to talk about today

is some more technical stuff.

It's some science-y stuff,

because I like that kind of stuff,

I like making your guys' brains hurt, so let's get into it.

The suspension on these cars is by far

one of the most engineered,

and arguably over-engineered portions of the car.

It is what is going to keep the driver and the car planted,

and let the driver have complete faith

in pushing the car to its absolute limits.

The suspension is arguably the part of a rally car

that makes it a rally car.

For the most part,

you'll see inverted strut or shock-absorbent designs

in most rally cars.

During a race, there are things like mud,

and gravel, and sticks, and sometimes small animals

that can be flung up into important components

underneath the race car.

This plus something known as side-loading

can really start to beat up a shock absorber.

In a perfect world, a strut would sit

centered directly over the wheel,

and travel only up and down

without any angle to it whatsoever.

But it's not a perfect world, is it, bud?

And there are things called camber, and caster,

and our friend that we just mentioned, side-load,

and a whole bunch of other stuff that come in to play,

so they really just kinda (bleep) everything up,

but by using an inverted shock absorber

you are protecting the damping components

by relieving what is usually a single point of stress

that is affected by all these things,

and expands that area over the rest of the housing

of the entire strut.

Paired with longer suspension arms

and the geometry of the rest of the suspension

being altered, these cars can typically have

up to 14 inches of suspension travel,

and now, if you need suspension,

not saying, like, we have inverted shocks

or anything like that, or things with 14 inches

of suspension travel, you know,

you can go check out

The second key factor into making rally cars what they are

is, of course, their engines and drivetrains.

So let's go ahead and take a look

at the Ford Fiesta that will be used

in the 2019 World Rally Championship this year.

The 1.6-liter turbocharged fire-breathing

four-cylinder monsters that power these cars pump out

a whopping 380 horsepower, (record scratching)

which, if you were to think about it,

you thought they produced a lot more,

but actually, this one,

it was just increased in 2007

from 315 horsepower up to 380.

Building these engines with upgraded camshafts,

forged internals, and a turbocharger,

these little cars can pack a serious punch.

You pair that with a six-speed sequential gearbox,

an all-wheel drive system

with an active center differential,

and you've got yourself

one hell of a little off road rollerskate.

With all this power and the rugged capabilities

offered by the suspension, these things

frickin' move at a good clip,

and when you're flying down the middle of the woods

or on the side of a mountain,

you're probably going to want to think about safety,

and yes, believe it or not, these crazy mo-fos

are takin' safety into a little somewhat of a consideration,

from the brake calipers, to the roll cages,

right down to the suits that the drivers wear,

all of the equipment made for these cars

are highly tested, ensuring the highest quality of safety.

Things like FIA-approved racing seats,

harnesses, spill kits, first aid kits,

fire extinguishers, all are the things you can find

in the cockpit of a rally car.

To keep the possibility of a fire from happening

in the event of a crash, regular gas tanks

are usually replaced with fuel bladders,

or cells made from Kevlar,

or carbon fiber-reinforced rubber,

and then next to that, all the glass is usually removed

and replaced with a plastic replacement

that is usually just somewhat taped into place

in case the driver needs to perform a Fast and Furious move

and kick out the window panel to get out

in case they roll over or somethin' like that,

which brings us to our last point

that we are gonna go over today,

and our quick breakdown

of what makes a rally car a rally car,

and that is, of course, the wheels and tires.

The wheels and tires,

just like every other aspect of these cars,

need to be rugged.

They need to be able to withstand the rough conditions,

the amount of stresses that they will be put through.

There are companies out there

that have the rally scene on lock,

companies like OZ, Sparco, fifteen52 have become staples

in the rally scene as far as the wheels

that these cars are running,

but even with that, if you are lookin' at

just getting into rallying, and you show up

to your first event, whether it be a class

or some beginner event, don't be surprised

when you see people start showing up

rocking a set of steelies, because the reason being

is that if they bump into something,

especially at an entry-level point,

steel wheels aren't going to crack

or break for the most part.

They're just going to bend,

and that's gonna allow them to at least

get back to the start point and not be stranded

in the side of the woods.

Other times, you'll see even OEM wheels on some cars,

just because they're able to give the performance

of what is needed right off the bat,

and when it comes to the tires that are being run,

just like any other type of motor sport,

you're going to have a specific-style tire

that you're going to be running

depending on what style of rally

the cars are going to be competing in.

These tires, for the most part,

are going to feature thicker sidewalls

than your normal street tires,

thicker, larger tread blocks,

and a harder tire compound,

so depending on if the cars are gonna be running on gravel,

asphalt, or even snow, it's going to determine

which tires are going to be ran that day.

Companies like Michelin and even Hoosier

specialize in manufacturing tires

rated for each type of condition.

So what it all comes down to,

is that the truth is that there is a lot

that goes into making a professional rally,

or rallycross-capable car, and they are

the furthest thing from stock that is even possible.

All the things that we talked about today

paired with aggressive aero, a crazy wrap,

and an even crazier driver behind the wheel

is why these cars are so frickin' spectacular.

So go ahead and let us know down in the comments

what your thoughts are on the whole rally racing thing,

and if you were to ever do it or not,

but that's gonna wrap it up for today,

don't forget, wheels, tires, suspension,, go pick up a shirt,

get entered to win a free set of Konig wheels.

I'm Gels from Fitment Industries,

we will see you later, peace.
