Down on the factory floor.
48
00:02:36,991 --> 00:02:38,924
Because of their decades
of experience
49
00:02:38,926 --> 00:02:41,460
Building formula one race cars,
50
00:02:41,462 --> 00:02:45,531
This individual craft-based
approach to car manufacturing

Lies deep in mclaren's dna.
52
00:02:48,602 --> 00:02:51,069
Breece mclaren, the founder,
was from new zealand.

00:02:51,071 --> 00:02:54,206
He built his first
formula one car in 1966.
54

Only ferrari has been
in the racing game longer.
55
00:02:57,211 --> 00:03:01,480
In the early '90s, they got into
road cars with the seminal f1.
56

A lot of the lessons
of the racetrack
57
00:03:02,950 --> 00:03:06,385
Are then brought over
into their production cars.
58
00:03:06,387 --> 00:03:07,920
Narrator: This is
the main building block,
59
00:03:07,922 --> 00:03:10,455
Or chassis of a mclaren car.
60
00:03:10,457 --> 00:03:13,258
It's called
a monocell or cage
61
00:03:13,260 --> 00:03:16,128
And the rest of the car
is built around it.
62
00:03:16,130 --> 00:03:19,498
The monocells are
premanufactured in austria
63
00:03:19,500 --> 00:03:21,366
And are made
from the same material
64
00:03:21,368 --> 00:03:25,270
Used in the modern
formula one race car.
65
00:03:25,272 --> 00:03:27,539
One of the major parts
or major materials we use
66
00:03:27,541 --> 00:03:28,707
Is carbon fiber.
67
00:03:28,709 --> 00:03:31,109
Carbon fiber is at the heart
of every mclaren.
68
00:03:31,111 --> 00:03:33,245
Mclaren revolutionized
formula one
69
00:03:33,247 --> 00:03:36,748
When they brought
in carbon fiber in 1981.
70
00:03:36,750 --> 00:03:40,285
It made the chassis five times
lighter and 10 times stronger
71
00:03:40,287 --> 00:03:43,555
And it is a key component
in the road cars today.
72
00:03:43,557 --> 00:03:44,823
If you compare carbon fiber
73
00:03:44,825 --> 00:03:46,825
To something like aluminum
or steel,
74
00:03:46,827 --> 00:03:50,596
That can be strong, actually
the strength to weight ratio
75
00:03:50,598 --> 00:03:52,698
Of carbon fiber
is what's so important.
76
00:03:52,700 --> 00:03:55,734
You don't need very much of it
to get the equivalent strength
77
00:03:55,736 --> 00:03:58,604
Of a much bigger amount
of another material.
78
00:03:58,606 --> 00:04:02,007
Narrator: But what exactly is
this wonder material,
79
00:04:02,009 --> 00:04:03,609
Carbon fiber?
80
00:04:03,611 --> 00:04:05,944
Carbon fiber is really
high-performance
81
00:04:05,946 --> 00:04:07,713
Composite material.
82
00:04:07,715 --> 00:04:11,583
It's something which contains
thin fibers of carbon,
83
00:04:11,585 --> 00:04:13,585
Which on their own
would be sort of floppy,
84
00:04:13,587 --> 00:04:16,321
But they have a certain
tensile strength to them.
85
00:04:16,323 --> 00:04:19,424
And then those fibers
are embedded in a polymer resin,
86
00:04:19,426 --> 00:04:22,728
Which is strong and has
a certain flexibility to it.
87
00:04:22,730 --> 00:04:24,296
But actually,
when you combine the two,
88
00:04:24,298 --> 00:04:26,832
You get something that's greater
than the sum of its parts.
89
00:04:26,834 --> 00:04:31,370
You get a super lightweight
high-performance material.
90
00:04:31,372 --> 00:04:33,872
Narrator: Just like their
formula one cars,
91
00:04:33,874 --> 00:04:38,243
Mclarens road cars are designed
with the driver in mind.
92
00:04:38,245 --> 00:04:40,045
They are built and designed
around the driver,
93
00:04:40,047 --> 00:04:42,614
So the driver is literally
at the center of the action.
94
00:04:42,616 --> 00:04:44,549
And then the monocage
and monocell
95
00:04:44,551 --> 00:04:47,619
Designed around the occupant.
96
00:04:47,621 --> 00:04:49,121
Narrator:
As soon as the monocage
97
00:04:49,123 --> 00:04:51,256
Chassis arrives
on the production line,
98
00:04:51,258 --> 00:04:54,226
The team starts to assemble
a car around this
99
00:04:54,228 --> 00:04:57,229
One essential building block.
100
00:04:57,231 --> 00:04:59,898
The first stage
is to add crumple zones
101
00:04:59,900 --> 00:05:03,468
And crash protection
around the car's interior.
102
00:05:03,470 --> 00:05:06,104
It's then taken for
what they call geometric
103
00:05:06,106 --> 00:05:08,273
And surface validation.
104
00:05:08,275 --> 00:05:12,344
Here, over 450 different
points of the car
105
00:05:12,346 --> 00:05:15,614
Are measured
to make sure every curve, line,
106
00:05:15,616 --> 00:05:18,550
And corner
is perfectly aligned
107
00:05:18,552 --> 00:05:20,152
And in proportion.
108
00:05:20,154 --> 00:05:22,187
We ensure
each mclaren car is perfect
109
00:05:22,189 --> 00:05:23,422
In every detail.
110
00:05:23,424 --> 00:05:24,790
Really, right from the off,
right from when we start
111
00:05:24,792 --> 00:05:28,894
The whole project
it's almost like watchmaking.
112
00:05:28,896 --> 00:05:30,095
Narrator:
Once the body has passed
113
00:05:30,097 --> 00:05:32,664
The surface validation test,
114
00:05:32,666 --> 00:05:36,668
The team can then start to build
up the car's exterior --
115
00:05:36,670 --> 00:05:40,439
The wing panels, side panels,
116
00:05:40,441 --> 00:05:43,942
And for non-convertibles --
the roof.
117
00:05:43,944 --> 00:05:46,645
Now it's ready to be painted.
118
00:05:46,647 --> 00:05:48,213
Before spraying,
119
00:05:48,215 --> 00:05:50,682
The whole body is wrapped
in plastic
120
00:05:50,684 --> 00:05:53,352
And the individual panels
are exposed,
121
00:05:53,354 --> 00:05:56,321
Primed, and sanded flat.
122
00:05:56,323 --> 00:06:01,793
Any contaminants are removed
with an anti-static gun
123
00:06:01,795 --> 00:06:05,197
And mclaren's secret
to their supercar's high speed
124
00:06:05,199 --> 00:06:10,302
Can be found
in the painting process.
125
00:06:10,304 --> 00:06:12,270
By using special particles
within the paint
126
00:06:12,272 --> 00:06:13,638
And a special paint process,
127
00:06:13,640 --> 00:06:15,107
We're actually able to decrease
the amount of paint
128
00:06:15,109 --> 00:06:16,408
We have to put on the car.
129
00:06:16,410 --> 00:06:21,313
And essentially deliver...
[ speaks indistinctly ]
130
00:06:21,315 --> 00:06:25,584
Narrator: It takes 24 hours to
paint a typical mclaren car
131
00:06:25,586 --> 00:06:29,554
And another 40 minutes in a hot
oven for it to fully dry.
132
00:06:29,556 --> 00:06:33,191
Finally, it's time to start
putting the car together.
133
00:06:33,193 --> 00:06:35,394
A loom of wires
is fed through the car
134
00:06:35,396 --> 00:06:37,195
To provide it with power.
135
00:06:37,197 --> 00:06:40,866
A typical mclaren is made up
of over a mile of cables
136
00:06:40,868 --> 00:06:43,802
And 2,000 individual circuits.
137
00:06:43,804 --> 00:06:46,605
Next, the beating heart
of the car.
138
00:06:46,607 --> 00:06:48,340
The most common engine type
139
00:06:48,342 --> 00:06:53,412
Is the m83018, a 3.8 liter
90 degree twin turbo
140
00:06:53,414 --> 00:06:55,881
Charged flat plain v8.
141
00:06:55,883 --> 00:06:59,518
The mclaren 720 s goes from
not 62 miles per hour
142
00:06:59,520 --> 00:07:01,787
In 2.9 seconds.
143
00:07:01,789 --> 00:07:05,190
Top speed --

Narrator:
Like most of the other parts
146
00:07:10,364 --> 00:07:14,699
That make up the mclaren,
the engine is made offsite.
147
00:07:14,701 --> 00:07:17,536
For mclaren,
outsourcing the parts
148
00:07:17,538 --> 00:07:20,639
Makes the most economic sense.
149
00:07:20,641 --> 00:07:24,009
To try to actually build
every single little bit of a car
150
00:07:24,011 --> 00:07:26,478
As well as assemble
the cars themselves
151
00:07:26,480 --> 00:07:28,647
Would be inefficient
from a process perspective,
152
00:07:28,649 --> 00:07:31,116
But also from
a cost perspective.
153
00:07:31,118 --> 00:07:33,118
Narrator:
Back on the assembly line,
154
00:07:33,120 --> 00:07:35,554
The brake discs and pistons
are installed.
155
00:07:35,556 --> 00:07:38,223
The brakes will slow
these high-performance wheels
156
00:07:38,225 --> 00:07:40,892
From 124 miles per hour
157
00:07:40,894 --> 00:07:45,630
To zero in just 4.6 seconds.

Now, a second groove slat
516
00:26:56,916 --> 00:26:59,650
Is placed
exactly on top of the first.
517
00:26:59,652 --> 00:27:04,121
The workers here call this
das sandwich and each sandwich
518
00:27:04,123 --> 00:27:06,590
Then goes into the drying wheel.
519
00:27:06,592 --> 00:27:09,193
The sandwiches are in the drying
wheel for one hour.
520
00:27:09,195 --> 00:27:12,696
The wheel rotates, squeezes
the sandwiches together,
521
00:27:12,698 --> 00:27:15,099
And this way leaves no gap.
522
00:27:15,101 --> 00:27:19,670
Just two pieces of wood
glued together.
523
00:27:19,672 --> 00:27:22,606
Narrator: A planing machine now
cuts them into pencils,
524
00:27:22,608 --> 00:27:27,945
Round, hexagonal, or triangular,
depending on the time.
525
00:27:27,947 --> 00:27:32,750
Up to 10 pencils can be cut
from a single sandwich.
526
00:27:32,752 --> 00:27:34,151
Faber prides themselves
527
00:27:34,153 --> 00:27:37,821
On producing strong
and durable pencils
528
00:27:37,823 --> 00:27:44,428
Qualities they ensure by putting
each one through a stress test.
529
00:27:44,430 --> 00:27:47,431
To figure out
if a pencil is good or not,
530
00:27:47,433 --> 00:27:51,568
A quick way of doing so
is to take a pencil,
531
00:27:51,570 --> 00:27:55,172
Hold it at a 45 degree angle,
and push down onto the scale.
532
00:27:55,174 --> 00:27:59,243
And the pencil will not break
before 2 1/2 kilos of pressure.
533
00:27:59,245 --> 00:28:00,711
If it would break before,
534
00:28:00,713 --> 00:28:02,613
We'd know there's
something wrong with it
535
00:28:02,615 --> 00:28:05,616
And test a couple of more to
figure out what's wrong with it.
536
00:28:05,618 --> 00:28:09,319
Let's see if the pencil
that we've just made
537
00:28:09,321 --> 00:28:10,954
Is of good quality.
538
00:28:10,956 --> 00:28:13,590
So 45 degrees
push down onto the scale
539
00:28:13,592 --> 00:28:18,962
And two and a half.
540
00:28:18,964 --> 00:28:21,098
Way past four or five kilos.
541
00:28:21,100 --> 00:28:23,901
So that pencil
is definitely good.
542
00:28:23,903 --> 00:28:26,003
Narrator: The pencils that pass
the stress test
543
00:28:26,005 --> 00:28:28,305
Move on to the next stage --
544
00:28:28,307 --> 00:28:29,973
The paint shop.
545
00:28:29,975 --> 00:28:35,145
This is where the pencils get
their first coating of paint.
546
00:28:35,147 --> 00:28:38,582
The pencils come through
the machine like that.
547
00:28:38,584 --> 00:28:42,453
So basically from here to here,
the felt ring would remove
548
00:28:42,455 --> 00:28:44,922
All the leftover dust
on the outside.
549
00:28:44,924 --> 00:28:46,824
In here then is the paint.
550
00:28:46,826 --> 00:28:50,127
In this case, dark green.
551
00:28:50,129 --> 00:28:51,962
The blue ring here
removes all the paint
552
00:28:51,964 --> 00:28:54,465
Except for the pencil
that has soaked into the wood
553
00:28:54,467 --> 00:28:57,568
And the pencils that come out
on the other end
554
00:28:57,570 --> 00:29:00,370
Go onto the band
and go through the drying tunnel
555
00:29:00,372 --> 00:29:03,407
To have the paint dry.
556
00:29:03,409 --> 00:29:07,111
Narrator: The graphite pencils
are painted faber green
557
00:29:07,113 --> 00:29:08,378
And the colored pencils
558
00:29:08,380 --> 00:29:12,316
Are painted to match
whatever color is on the inside.
559
00:29:12,318 --> 00:29:15,185
Once the paint's dried,
the pencils come back
560
00:29:15,187 --> 00:29:16,587
And do this again.
561
00:29:16,589 --> 00:29:19,690
They come back and do this again
and they do this up to six times
562
00:29:19,692 --> 00:29:22,893
Because the pencils need
numerous layers of paint
563
00:29:22,895 --> 00:29:27,464
To have
a really nice finished coat.
564
00:29:27,466 --> 00:29:30,801
Narrator: The company's logo,
two jousting knights
565
00:29:30,803 --> 00:29:35,339
Is stamped in gold leaf
on every pencil,
566
00:29:35,341 --> 00:29:37,374
And the colored pencils
are also stamped
567
00:29:37,376 --> 00:29:40,043
With their color identification.
568
00:29:40,045 --> 00:29:44,948
In this case, cadmium red.
569
00:29:44,950 --> 00:29:46,850
So the last thing that
we're now missing
570
00:29:46,852 --> 00:29:48,552
Is only the sharpening.
571

It's now being referred to
as a fifth flavor.
608

In the west,

Four flavors -- bitter,
sweet, salty, and sour.

We also acknowledge
a flavor called umami,

Which roughly translates
as savory or brothy.
613

00:36:40,499 --> 00:36:43,300
And the sodium chloride
is dissolved in water
689
00:36:43,302 --> 00:36:47,003
To produce a huge pool
of 20% salt brine.
690
00:36:47,005 --> 00:36:50,106
The brine is pumped
through the koji mix.
691
00:36:50,108 --> 00:36:53,877
It prevents the growth of
any undesirable microorganisms
692
00:36:53,879 --> 00:36:57,380
And acts as a preservative
for the koji.
693
00:36:57,382 --> 00:37:01,017
Once that's done,
lactic acid bacteria,
694
00:37:01,019 --> 00:37:05,021
Which is brine-friendly,
is added along with yeasts
695
00:37:05,023 --> 00:37:08,792
That further promote
the fermentation process.
696
00:37:08,794 --> 00:37:12,963
This transforms the koji
into moromi.
697
00:37:12,965 --> 00:37:16,666
The moromi mash is then
transported by spiral pumps
698
00:37:16,668 --> 00:37:18,401
Through a network of pipes
699
00:37:18,403 --> 00:37:21,938
Into gigantic
steel fermentation vats.
700
00:37:21,940 --> 00:37:25,976
This plant alone has
50 in constant use,
701
00:37:25,978 --> 00:37:29,212
It's stored for six months
and watched over as the soy
702
00:37:29,214 --> 00:37:32,282
And wheat paste turns
into a semi-liquid,
703
00:37:32,284 --> 00:37:35,118
Reddish brown, mature mash.
704
00:37:35,120 --> 00:37:37,821
A lot of soy sauce you buy
in shops will be made
705
00:37:37,823 --> 00:37:39,589
Using chemical processes.
706
00:37:39,591 --> 00:37:43,460
But the traditional method
uses mold and is natural.
707
00:37:43,462 --> 00:37:46,296
And in order for it
to be called natural soy sauce,
708
00:37:46,298 --> 00:37:49,232
It has to use mold.
709
00:37:49,234 --> 00:37:52,302
Narrator: Aspergillus mold has
broken down the grain protein
710
00:37:52,304 --> 00:37:54,571
Into free amino acids
711
00:37:54,573 --> 00:37:57,440
And the protein fragments
into starches
712
00:37:57,442 --> 00:37:59,876
And then into simple sugars.
713
00:37:59,878 --> 00:38:03,546
Now the lactic acid bacteria
ferments those sugars,
714
00:38:03,548 --> 00:38:04,881
Which gradually develops
715
00:38:04,883 --> 00:38:08,151
