1
00:00:02,546 --> 00:00:05,015
[Tory] Okay, here we go.
Electric car...
2
00:00:05,015 --> 00:00:06,850
One hundred percent charge.
3
00:00:06,850 --> 00:00:08,985
- Ready?
- So, I'm going to put this
in sport mode.
4
00:00:08,985 --> 00:00:10,554
- Okay.
- 'Cause that's what I do.
5
00:00:10,554 --> 00:00:12,789
[Bisi] I hope Tory's wearing
some brown boxers.
6
00:00:12,789 --> 00:00:14,691
Three, two, one...
7
00:00:14,691 --> 00:00:16,793
- [Tory] Go.
- Go, go, go!
8
00:00:16,793 --> 00:00:18,462
[Tory] I know!
9
00:00:18,462 --> 00:00:20,231
- Come on!
- [Tory] Yeah...
10
00:00:20,231 --> 00:00:21,265
Oh, my God!
11
00:00:22,933 --> 00:00:25,035
- [laughs]
- That's a fast EV, sir.
12
00:00:25,035 --> 00:00:27,338
[Tory] But as the battery
starts dying...
13
00:00:27,338 --> 00:00:30,574
- "Decreases."
- See, you say "decreases,"
14
00:00:30,574 --> 00:00:32,343
- I say "dying."
- [both laugh]
15
00:00:32,343 --> 00:00:36,513
[Faye] Three, two, one, go!
16
00:00:42,119 --> 00:00:43,520
[narrator] Meet the team.
17
00:00:43,520 --> 00:00:44,988
[screaming]
18
00:00:44,988 --> 00:00:46,523
[Tory] This might be
the miracle coolant
19
00:00:46,523 --> 00:00:48,425
that everybody's
been searching for.
20
00:00:48,425 --> 00:00:50,161
Oh, no!
21
00:00:50,161 --> 00:00:51,995
[narrator] With the
mechanical expertise...
22
00:00:51,995 --> 00:00:53,897
[Faye] My main concern
is structural integrity.
23
00:00:53,897 --> 00:00:55,899
[narrator] ...to test
all things automotive.
24
00:00:55,899 --> 00:00:57,934
- Oh! [laughing]
- The engine died!
25
00:00:57,934 --> 00:01:01,172
[Bisi] The more air
we push through,
the more fuel siphon out.
26
00:01:01,172 --> 00:01:02,773
And boom!
27
00:01:02,773 --> 00:01:05,442
[narrator]
This is Motor MythBusters.
28
00:01:05,442 --> 00:01:07,278
- [Tory] Hit it!
- [engine revving]
29
00:01:07,278 --> 00:01:10,181
-[narrator] Where science...
-[Tory] Whoa!
30
00:01:11,182 --> 00:01:12,816
[narrator]
...meets the streets.
31
00:01:15,552 --> 00:01:17,688
[Tory] I'm starting to feel
differently about these
electric cars.
32
00:01:17,688 --> 00:01:19,022
[Bisi] Oh, stop it.
33
00:01:19,022 --> 00:01:21,358
I thought you said
we'll be able to get there
and back.
34
00:01:21,358 --> 00:01:22,759
All we need is ten minutes.
35
00:01:22,759 --> 00:01:24,027
I'mma charge up ten minutes,
36
00:01:24,027 --> 00:01:26,363
and we'll get back on the road
and we'll make it to the shop.
37
00:01:26,363 --> 00:01:28,765
It's not that long.
It's like getting coffee
or something.
38
00:01:28,765 --> 00:01:30,000
At least I brought
something to read.
39
00:01:30,000 --> 00:01:31,202
There's just no place
to get coffee.
40
00:01:31,202 --> 00:01:33,604
Hey, do you want to learn
about the metallurgy of iron?
41
00:01:33,604 --> 00:01:35,206
No.
42
00:01:35,206 --> 00:01:36,873
Okay, so, by heating
from 800 degrees,
43
00:01:36,873 --> 00:01:40,010
the structure will be changed.
To 1,300 degrees Fahrenheit,
44
00:01:40,010 --> 00:01:41,345
the metal will be softened.
45
00:01:41,345 --> 00:01:42,713
[yawns]
46
00:01:46,817 --> 00:01:47,918
[scatting]
47
00:01:49,220 --> 00:01:50,221
Okay, that's a maybe.
48
00:01:50,221 --> 00:01:53,023
Crush it, Tory! Kill it!
49
00:01:53,023 --> 00:01:54,791
[bird squawking]
50
00:01:54,791 --> 00:01:56,827
All right, so, can we
drive this thing home yet?
51
00:01:56,827 --> 00:01:59,996
- I'm at 25% charged right now.
- Will that get us home?
52
00:01:59,996 --> 00:02:01,298
Not very quickly.
53
00:02:01,298 --> 00:02:03,133
- [laughs]
- Ugh! Why not very quickly?
54
00:02:03,133 --> 00:02:04,701
Well, at 25%,
55
00:02:04,701 --> 00:02:07,571
I don't think I'll have
as much energy or power
as when I'm fully charged.
56
00:02:07,571 --> 00:02:08,705
No, that's not what they say.
57
00:02:08,705 --> 00:02:10,541
People think that
electric cars will perform
the same
58
00:02:10,541 --> 00:02:12,243
no matter what the state
of charge of the battery is.
59
00:02:12,243 --> 00:02:13,544
And you're saying that's not
what you're experiencing.
60
00:02:13,544 --> 00:02:14,745
No, that's not our experience.
Mm-mm.
61
00:02:14,745 --> 00:02:16,613
There's a myth here, folks.
Help me out.
62
00:02:16,613 --> 00:02:20,617
All right, so the myth is
an electric car
with 25% charge
63
00:02:20,617 --> 00:02:24,054
will not perform as well
when it's fully charged.
64
00:02:24,054 --> 00:02:25,756
- I would like to test that.
- All right.
65
00:02:25,756 --> 00:02:27,691
Sounds like we're going
to the race track.
66
00:02:29,159 --> 00:02:33,096
[narrator] Yep.
Testing this tall tale
will need speed and space
67
00:02:33,096 --> 00:02:35,131
to put the pedal to the metal.
68
00:02:35,131 --> 00:02:36,933
Ask any auto owner
69
00:02:36,933 --> 00:02:40,571
if their car's performance
fades as the fuel gauge falls
70
00:02:40,571 --> 00:02:42,539
and you'd be
laughed out of town.
71
00:02:44,808 --> 00:02:46,677
But when it comes to an EV,
72
00:02:46,677 --> 00:02:50,914
Bisi believes
battery depletion
decreases acceleration
73
00:02:50,914 --> 00:02:52,383
and reduces performance.
74
00:02:55,852 --> 00:02:58,789
To test that, a relatable
mid-range family EV
75
00:02:58,789 --> 00:03:02,726
will be put through its paces
at full charge and 25%.
76
00:03:04,928 --> 00:03:09,366
And for an objective baseline,
to its gasoline-powered twin.
77
00:03:12,969 --> 00:03:14,705
[Faye] All right, you guys.
So we got our cars.
78
00:03:14,705 --> 00:03:16,307
What do we know
about these cars?
79
00:03:16,307 --> 00:03:19,209
- These are the perfect chassis
to test this. It really is.
- Okay. All right.
80
00:03:19,209 --> 00:03:20,911
[Bisi] I have a lot
of information for you.
81
00:03:20,911 --> 00:03:22,212
[Tory] Is this gonna be
a long lecture?
82
00:03:22,212 --> 00:03:24,315
No. Very short, actually.
You'll find
it's quite appealing.
83
00:03:24,315 --> 00:03:25,882
- I don't like lectures.
- Nah, me neither.
84
00:03:25,882 --> 00:03:29,019
Before you get out of control,
I will share with you
85
00:03:29,019 --> 00:03:31,455
that these vehicles
are quite evenly matched.
86
00:03:31,455 --> 00:03:32,889
- Okay.
- That shows you how.
87
00:03:32,889 --> 00:03:35,559
The EV has 201 horsepower,
88
00:03:35,559 --> 00:03:37,361
the internal combustion, 175.
89
00:03:37,361 --> 00:03:42,533
However, the EV
is much heavier
at 3,770 pounds,
90
00:03:42,533 --> 00:03:46,770
while the gasoline chassis
is 3,276 pounds.
91
00:03:46,770 --> 00:03:48,705
However,
worst part of the weight,
92
00:03:48,705 --> 00:03:50,341
look at that ratio.
93
00:03:50,341 --> 00:03:55,879
0.0533 on the EV,
0.0534 on the petrol.
94
00:03:55,879 --> 00:03:59,850
That's only a tenth
of a thousandth
difference in that ratio.
95
00:04:03,354 --> 00:04:05,456
They're perfectly matched
for additional contacts
96
00:04:05,456 --> 00:04:08,359
while tackling
the hypothesis that
an EV's performance
97
00:04:08,359 --> 00:04:10,794
is compromised
by charge depletion.
98
00:04:10,794 --> 00:04:12,796
- Science!
- Right.
99
00:04:12,796 --> 00:04:16,633
[Bisi] To test it,
we'll track two key metrics
over a quarter-mile.
100
00:04:16,633 --> 00:04:18,969
Top speed
and for acceleration,
101
00:04:18,969 --> 00:04:21,838
the standard time
to go from zero to sixty.
102
00:04:24,508 --> 00:04:28,211
So this is
100% state of charge
in the battery pack,
103
00:04:28,211 --> 00:04:31,748
and I have data logging
equipment installed
using global positioning
104
00:04:31,748 --> 00:04:33,384
opposed to the vehicle speed
on the car.
105
00:04:33,384 --> 00:04:36,853
Because with the vehicle speed
on the vehicle, if I spin out,
106
00:04:36,853 --> 00:04:38,655
my tires will give me
a higher mile/hour.
107
00:04:38,655 --> 00:04:40,256
So this is a lot more accurate
108
00:04:40,256 --> 00:04:43,394
using global positioning
satellites to give us
accurate data.
109
00:04:43,394 --> 00:04:44,595
That's a great point.
110
00:04:44,595 --> 00:04:47,230
We'll be able to tell how long
it takes you to get down,
111
00:04:47,230 --> 00:04:50,434
and we'll be able to see
how quick
you get off the line.
112
00:04:51,635 --> 00:04:53,604
- You ready?
- So, I'm going to put this
in sport mode.
113
00:04:53,604 --> 00:04:55,271
- Okay.
- 'Cause that's what I do.
114
00:04:55,271 --> 00:04:56,607
- All right.
- All right.
115
00:04:56,607 --> 00:04:58,575
Okay, I'll need your help
with a countdown.
Let me know.
116
00:04:58,575 --> 00:05:01,845
Here we go.
I'm gonna give you a help.
Here we go.
117
00:05:01,845 --> 00:05:04,948
In three, two, one, go.
118
00:05:08,284 --> 00:05:10,621
You got a little bit
of slippage there.
119
00:05:10,621 --> 00:05:12,923
Oh, I definitely feel
the torque.
120
00:05:12,923 --> 00:05:14,090
Yes, It's nice, isn't it?
121
00:05:14,090 --> 00:05:16,527
Sixty miles an hour.
122
00:05:16,527 --> 00:05:18,429
Seventy miles an hour.
123
00:05:18,429 --> 00:05:20,697
All right,
here comes the quarter mark.
124
00:05:24,134 --> 00:05:27,270
- Ninety-six miles per hour.
- [Bisi] Not bad!
125
00:05:27,270 --> 00:05:29,172
That's fast, sir.
126
00:05:29,172 --> 00:05:31,642
- [Tory] But I mean, you know,
it is 100% charged.
- Yes.
127
00:05:31,642 --> 00:05:35,712
But as the battery
starts dying,
you start losing power,
128
00:05:35,712 --> 00:05:37,313
and especially at 25%,
129
00:05:37,313 --> 00:05:39,483
I have a feeling you're not
going to see these numbers.
130
00:05:39,483 --> 00:05:41,818
I wouldn't say,
"As the battery starts dying,"
131
00:05:41,818 --> 00:05:44,054
I'll say "As the state
of charge decreases."
132
00:05:44,054 --> 00:05:47,991
See, you say "decreases,"
I say "dying."
133
00:05:47,991 --> 00:05:50,727
[both laughing]
134
00:05:51,862 --> 00:05:53,229
[Bisi] Tory, funny guy.
135
00:05:53,229 --> 00:05:56,032
But seriously,
compared to your
standard SUV,
136
00:05:56,032 --> 00:05:58,902
off the line,
this EV is quick.
137
00:05:58,902 --> 00:06:01,838
Why?
It's all about the torque.
138
00:06:04,475 --> 00:06:06,477
Push the pedal
and within milliseconds,
139
00:06:06,477 --> 00:06:08,111
the controller
completes the circuit.
140
00:06:08,111 --> 00:06:10,881
And the motor,
the current
and electromagnetic field
141
00:06:10,881 --> 00:06:12,983
interact via the Lorentz force
142
00:06:12,983 --> 00:06:14,618
producing instant torque.
143
00:06:14,618 --> 00:06:17,621
With the motor coupled
directly to the drivetrain,
boom, you're off.
144
00:06:23,259 --> 00:06:26,663
[narrator] And to find out
how effective
that near-instant torque is,
145
00:06:26,663 --> 00:06:30,333
Tory's jumping in
the EV's sibling.
146
00:06:30,333 --> 00:06:35,071
The gasoline-powered partner
with near-identical
power to weight ratio,
147
00:06:35,071 --> 00:06:37,808
will provide an interesting
objective baseline.
148
00:06:39,175 --> 00:06:40,611
You do not trust me.
149
00:06:40,611 --> 00:06:43,914
You're right.
I don't trust you because
I feel like you might lift.
150
00:06:43,914 --> 00:06:45,248
- Why would I do that?
- I don't know.
151
00:06:45,248 --> 00:06:47,518
You're so excited
about the electric car.
152
00:06:47,518 --> 00:06:50,253
I am excited,
but I am a scientist first.
153
00:06:50,253 --> 00:06:51,988
Data collection
is very important to me.
154
00:06:51,988 --> 00:06:53,557
Especially
honest data collection.
155
00:06:54,625 --> 00:06:57,994
Okay, Bisi.
Speed, performance.
156
00:06:57,994 --> 00:06:59,863
Internal combustion engine.
157
00:06:59,863 --> 00:07:01,064
[Bisi] Yes.
158
00:07:02,132 --> 00:07:03,900
- We're in sport mode...
- Okay. Sport mode...
159
00:07:03,900 --> 00:07:05,368
- ...on the start line.
- ...on the start line.
160
00:07:05,368 --> 00:07:09,405
And on three, two, one, go.
161
00:07:11,141 --> 00:07:13,544
- [Bisi] Oh!
- Oh, my God.
Do you feel that lag?
162
00:07:13,544 --> 00:07:16,112
Does the car know
we're doing a test?
[laughing]
163
00:07:16,112 --> 00:07:19,382
Do you realize
we're trying to go fast here?
164
00:07:21,384 --> 00:07:22,586
[Bisi] Seventy miles an hour.
165
00:07:22,619 --> 00:07:24,454
- [Tory] I can't push the pedal
down any farther.
- [laughs]
166
00:07:24,454 --> 00:07:28,659
[Bisi] Eighty miles an hour.
Halfway, almost there...
And that's it.
167
00:07:29,593 --> 00:07:31,427
- Ooh!
- [Tory] 88 miles an hour.
168
00:07:31,427 --> 00:07:33,063
That's slower.
169
00:07:33,063 --> 00:07:36,066
[Tory] Yeah.
Despite having equal power
to weight ratios,
170
00:07:36,066 --> 00:07:39,069
top speed and acceleration
are way down.
171
00:07:39,069 --> 00:07:40,236
And you know why?
172
00:07:40,236 --> 00:07:42,939
- [Bisi] Oh.
- Oh, my God.
You feel that lag?
173
00:07:42,939 --> 00:07:48,044
A combustion engine takes time
to fire up, and get
those pistons cranking.
174
00:07:48,044 --> 00:07:53,083
Yeah, it was kind of obvious
that gas took a little bit
more time to get going.
175
00:07:53,083 --> 00:07:54,317
[Bisi laughs]
176
00:07:54,317 --> 00:07:57,287
The EV, it's gone
in 60 milliseconds.
177
00:07:58,922 --> 00:08:01,592
[narrator]
While the battery is being
drained to 25 percent for
178
00:08:01,592 --> 00:08:03,493
the most critical comparison,
179
00:08:03,493 --> 00:08:05,996
Tory, well,
he just wants to beat Bisi.
180
00:08:05,996 --> 00:08:09,866
His plan, lighten the load
to increase
power to weight ratio.
181
00:08:11,367 --> 00:08:13,904
The beauty is that
at a quarter tank of gas,
182
00:08:13,904 --> 00:08:17,507
You've instantly lost
85 pounds of weight.
183
00:08:17,507 --> 00:08:20,911
[narrator] Go mean and lean
by dumping gasoline.
184
00:08:20,911 --> 00:08:24,514
Yeah, it's like kicking out
a passenger. Small time. Yeah.
185
00:08:24,514 --> 00:08:27,851
[narrator] Solid theory,
unless Tory forgets
to do the math,
186
00:08:27,851 --> 00:08:30,621
but that would be fuel-ish.
187
00:08:33,223 --> 00:08:34,090
[Tory] All right, Bisi.
188
00:08:34,090 --> 00:08:35,626
- [Bisi] Okay.
- We ready?
189
00:08:35,626 --> 00:08:37,260
Quarter tank.
Ready when you are.
190
00:08:37,260 --> 00:08:38,294
- All right. Here we go.
- You ready?
191
00:08:39,129 --> 00:08:42,032
Three, two, one, go.
192
00:08:43,399 --> 00:08:44,868
Oh, that's good.
193
00:08:44,868 --> 00:08:47,003
- It's--
- That's good.
194
00:08:47,003 --> 00:08:48,438
A little sluggy.
195
00:08:48,438 --> 00:08:49,673
That was good though.
196
00:08:49,673 --> 00:08:52,776
You hit the gas
and it takes a second
for to wake up.
197
00:08:57,447 --> 00:08:58,682
[all exclaiming]
198
00:08:58,682 --> 00:08:59,816
- Right there.
- That's it.
199
00:09:01,184 --> 00:09:03,186
- Eighty nine.
- Eighty nine miles an hour.
200
00:09:03,186 --> 00:09:04,788
Wow!
201
00:09:04,788 --> 00:09:08,058
[narrator] Turns out
Tory's plan wasn't sound
in the pound department.
202
00:09:08,825 --> 00:09:10,961
The fueled up attempt tanked.
203
00:09:14,130 --> 00:09:17,033
The numbers
torque for themselves.
204
00:09:17,033 --> 00:09:20,971
Yeah, it was kind of obvious
when we were doing those runs.
205
00:09:20,971 --> 00:09:24,775
- The gas took a little bit
more time to get going.
- [laughs]
206
00:09:24,775 --> 00:09:27,210
You, look at
how happy you are.
207
00:09:27,210 --> 00:09:28,845
Allow me to bask in the glory.
208
00:09:30,747 --> 00:09:33,349
[narrator] But the myth
in question
remains unanswered.
209
00:09:33,349 --> 00:09:37,153
Let's run the test again,
but with battery down to 25%.
210
00:09:37,153 --> 00:09:39,522
[narrator]
Will the undercharged EV's
performance
211
00:09:39,522 --> 00:09:42,092
be adversely affected
over the quarter mile?
212
00:09:44,094 --> 00:09:45,361
- Okay, here we go.
- Here we go.
213
00:09:45,361 --> 00:09:50,366
This is 25% capacity
of the electric car.
214
00:09:50,366 --> 00:09:51,501
Make sure I'm in sport mode.
215
00:09:52,568 --> 00:09:54,337
- Let's go.
- Okay, here we go.
216
00:09:54,337 --> 00:09:56,406
In three, two, one.
217
00:09:56,406 --> 00:09:57,507
Hit it.
218
00:09:59,109 --> 00:10:02,378
- Not as much kick
as 100% capacity.
- Absolutely not.
219
00:10:05,015 --> 00:10:07,417
Seventy five miles an hour.
80 miles an hour.
220
00:10:08,351 --> 00:10:10,053
We made it. [cheering]
221
00:10:11,054 --> 00:10:13,323
And we're...
222
00:10:13,323 --> 00:10:15,525
All right, you guys,
I'm really stoked
for these results.
223
00:10:15,525 --> 00:10:16,827
What do we got?
What do we got?
224
00:10:16,827 --> 00:10:19,863
This is EV
with 100% state of charge.
225
00:10:19,863 --> 00:10:23,099
Versus 25% capacity,
0 to 60.
226
00:10:23,099 --> 00:10:26,169
- And top speed.
- Numbers don't lie.
227
00:10:26,169 --> 00:10:27,570
No, they do not.
228
00:10:29,639 --> 00:10:32,275
So far, all we've done
is like straight line stuff.
229
00:10:32,275 --> 00:10:34,110
- Yeah.
- And that's cool and all.
230
00:10:34,110 --> 00:10:36,880
But what about windy,
twisty road course?
231
00:10:36,880 --> 00:10:38,949
- I'm game for it.
- That sounds
like a great idea.
232
00:10:40,116 --> 00:10:42,285
[man] This is going
to be interesting.
233
00:10:42,285 --> 00:10:44,687
Quarter mile,
industry standard
performance test
234
00:10:44,687 --> 00:10:47,390
focuses on
off the line acceleration.
235
00:10:47,390 --> 00:10:49,025
But what about
a more relatable drive
236
00:10:49,025 --> 00:10:52,062
for the average owner
of a car like this?
237
00:10:52,062 --> 00:10:55,899
A trip to the store
or commute over, say,
three laps.
238
00:10:55,899 --> 00:10:59,235
Seven half miles.
Will the performance
variables change?
239
00:10:59,235 --> 00:11:01,204
Will the distance
make a difference?
240
00:11:01,204 --> 00:11:03,539
And if fully
and undercharged EVs even out.
241
00:11:04,674 --> 00:11:06,042
I think we should do
three laps,
242
00:11:06,076 --> 00:11:08,845
and then we'll just average
the times and see
which one's better.
243
00:11:08,845 --> 00:11:10,680
Okay, sounds good.
244
00:11:10,680 --> 00:11:14,017
So, that will be the metric
we use in the final test.
245
00:11:14,017 --> 00:11:17,387
Compare the under charge
and fully charged EVs.
246
00:11:17,387 --> 00:11:19,122
But first up for a baseline
247
00:11:19,122 --> 00:11:23,359
and to help BC
set consistent lap times
in the real test,
248
00:11:23,359 --> 00:11:26,162
let's take my old gas
guzzling friend for spin.
249
00:11:28,564 --> 00:11:33,036
Thing is internal combustion
engine lap time test.
250
00:11:33,036 --> 00:11:35,538
Here we go in three, two, one.
251
00:11:39,042 --> 00:11:42,012
- Man, off the line.
- I know,
it's not the same as a--
252
00:11:42,012 --> 00:11:43,479
No, the electric car
has way more torque.
253
00:11:43,479 --> 00:11:46,582
- Are you actually--
- My foot's on the floor.
254
00:11:46,582 --> 00:11:48,718
This thing,
1.6 liters of fury.
255
00:11:51,021 --> 00:11:52,455
- Foot's on the floor.
- I have a feeling.
256
00:11:53,556 --> 00:11:55,025
My foot's on the floor!
257
00:11:55,025 --> 00:11:57,327
- My God!
- How dare you.
258
00:11:57,327 --> 00:12:01,131
Your time is better
on this second lap, though.
That's for sure.
259
00:12:01,131 --> 00:12:03,166
- Push it, push it.
- Final lap, final lap,
final lap.
260
00:12:05,368 --> 00:12:08,304
See, it's good to have us here
to keep you through.
261
00:12:08,304 --> 00:12:10,473
I feel like you wouldn't
be pushing so hard.
262
00:12:11,307 --> 00:12:12,442
Almost there, almost there.
263
00:12:17,113 --> 00:12:18,281
That's good.
264
00:12:18,281 --> 00:12:21,184
It was pretty consistent
unlike the electric vehicle.
265
00:12:21,184 --> 00:12:22,452
That's kind of
what you would expect.
266
00:12:22,452 --> 00:12:26,322
You would expect to see
that just consistent power.
267
00:12:26,322 --> 00:12:28,591
[man] Okay, now have a feel
for the track.
268
00:12:28,591 --> 00:12:30,593
And we have
a lap time benchmark.
269
00:12:30,593 --> 00:12:36,199
You came away with
an average time of 1:45:01
270
00:12:37,667 --> 00:12:40,303
[man] It's time
for the fully charged EV.
271
00:12:40,303 --> 00:12:42,572
I hope Tory's wearing
some brown boxers.
272
00:12:43,139 --> 00:12:44,540
Okay, here we go.
273
00:12:45,175 --> 00:12:49,712
[Tory] Three, two, one, go!
274
00:12:49,712 --> 00:12:51,781
Oh, look at that.
There's so much torque.
275
00:12:51,781 --> 00:12:53,683
- Oh, yeah!
- We've lost traction.
276
00:12:56,086 --> 00:12:57,320
Oh!
277
00:12:57,320 --> 00:12:58,721
The torque is amazing.
278
00:12:58,721 --> 00:13:00,723
It's like
there's no lag whatsoever.
279
00:13:02,225 --> 00:13:04,127
I came in full throttle...
So much torque!
280
00:13:04,127 --> 00:13:05,428
He's got it in full throttle.
281
00:13:06,496 --> 00:13:09,232
You're such a good driver.
Oh, my God.
282
00:13:10,934 --> 00:13:11,902
This is all power.
283
00:13:14,470 --> 00:13:15,771
Lap two!
284
00:13:15,771 --> 00:13:18,108
- Wow, that was pretty fast.
- Yeah, that was pretty good.
285
00:13:19,309 --> 00:13:22,178
- You're came back there?
- I am doing good.
286
00:13:22,946 --> 00:13:24,114
One more lap to go.
287
00:13:25,581 --> 00:13:27,417
- Is this good?
- You're good.
288
00:13:28,618 --> 00:13:29,819
- I'm drifting.
- Yes, yes, yes.
289
00:13:31,487 --> 00:13:33,957
- Oh, my God, that's--
- That was awesome.
290
00:13:37,928 --> 00:13:40,796
Well, BC,
that was incredible driving.
291
00:13:40,796 --> 00:13:42,232
I had so much fun
with that thing.
292
00:13:42,232 --> 00:13:44,634
It was peeling out and just--
Oh, my God.
293
00:13:44,634 --> 00:13:47,003
So responsive. I love EVs.
I really do.
294
00:13:47,003 --> 00:13:50,140
Now it's time to go on
to 25% capacity.
295
00:13:50,140 --> 00:13:52,575
And just like before,
we'll do three laps.
296
00:13:52,575 --> 00:13:53,977
Keep it consistent,
297
00:13:53,977 --> 00:13:57,413
and see how it performs
compared to when it was
at full capacity.
298
00:13:57,413 --> 00:13:58,448
Sounds good.
299
00:13:59,182 --> 00:14:00,683
Okay, here we go.
300
00:14:00,683 --> 00:14:03,086
This is electric car.
301
00:14:03,086 --> 00:14:06,022
25% battery capacity.
302
00:14:06,022 --> 00:14:07,523
[narrator] With BC amped up,
303
00:14:07,523 --> 00:14:09,792
will the longer distance drive
make a difference?
304
00:14:10,726 --> 00:14:12,228
On the flat quarter mile.
305
00:14:12,228 --> 00:14:16,599
the fully charged car
significantly outperformed
the depleted EV.
306
00:14:18,734 --> 00:14:19,735
This is it.
307
00:14:19,735 --> 00:14:22,738
- Okay, three...
-The final countdown...
308
00:14:22,738 --> 00:14:26,709
- ...two.
-...to test the definitive
real world scenario.
309
00:14:27,643 --> 00:14:28,711
One, go!
310
00:14:30,113 --> 00:14:32,415
Yeah, that felt so different.
311
00:14:32,415 --> 00:14:35,451
- There was no like
off the line...
- No.
312
00:14:35,451 --> 00:14:37,620
- I mean, I gotta say--
- In nearly spinned tires.
313
00:14:37,620 --> 00:14:39,689
Oh. This is not good.
314
00:14:39,689 --> 00:14:41,992
- Go, go, go.
- I know.
315
00:14:41,992 --> 00:14:44,660
All right, so we're going
into the first lap.
316
00:14:45,828 --> 00:14:47,630
Oh, my God!
317
00:14:47,630 --> 00:14:50,700
You can do it, you can do it.
Come on! Come on!
318
00:14:50,700 --> 00:14:54,070
Oh, I can feel it.
Struggling in the uphill.
319
00:14:56,006 --> 00:14:57,473
I feel like
my foots on the floor.
320
00:14:57,473 --> 00:14:58,908
You're not coming.
321
00:15:00,276 --> 00:15:02,012
Wait, you're going.
That's not that bad.
322
00:15:03,879 --> 00:15:06,882
- Come on!
- Oh, my God!
323
00:15:06,882 --> 00:15:09,485
I wonder if we're gonna
make it to that third lap.
324
00:15:09,485 --> 00:15:10,853
Oh, my God!
325
00:15:11,921 --> 00:15:13,623
As the battery is dying,
326
00:15:13,623 --> 00:15:16,292
we tend to be doing
a similar interesting.
327
00:15:16,292 --> 00:15:17,560
You can do it, one more!
328
00:15:19,362 --> 00:15:20,596
Come on!
329
00:15:23,699 --> 00:15:25,401
- Well that was the worst?
- Yeah.
330
00:15:25,401 --> 00:15:29,705
The performance kept getting
less and less after each lap.
331
00:15:29,705 --> 00:15:32,875
Yeah, 100%. Jumping off
the starting light,
332
00:15:32,875 --> 00:15:34,444
you instantly
feel that torque.
333
00:15:35,745 --> 00:15:37,180
All right, let's take a look
at some data here.
334
00:15:37,180 --> 00:15:39,882
Electric car. 100% charge.
335
00:15:39,882 --> 00:15:45,055
You came away
with an average time
of 1:42:65.
336
00:15:45,055 --> 00:15:47,223
- Nice.
- That's a pretty
respectful time.
337
00:15:47,223 --> 00:15:52,095
But more importantly,
what is that compared to
the 25% EV?
338
00:15:52,095 --> 00:15:55,331
Okay, electric vehicle
did extremely well
with high state of charges.
339
00:15:55,331 --> 00:15:58,701
You came away with
an average time of 1:46.
340
00:15:59,969 --> 00:16:02,172
As the battery state
charge went down,
341
00:16:02,172 --> 00:16:05,241
and hence the voltage
to the motors went down,
342
00:16:05,241 --> 00:16:07,177
the performance
suffered accordingly.
343
00:16:07,177 --> 00:16:08,478
With a full charge,
344
00:16:08,478 --> 00:16:11,414
we were almost three and
a half seconds faster per lap.
345
00:16:11,414 --> 00:16:14,984
And that shows the beauty
of energy density
which gas didn't cause.
346
00:16:14,984 --> 00:16:17,520
You don't suffer when you have
a full tank or partial tank
347
00:16:17,520 --> 00:16:18,954
is still the same.
348
00:16:18,954 --> 00:16:21,491
While with electric cars,
at least with
today's technology,
349
00:16:21,491 --> 00:16:23,493
the chemistry dictates
that we have less energy
350
00:16:23,493 --> 00:16:25,828
as our battery state of charge
goes down.
351
00:16:25,828 --> 00:16:27,263
But, you know,
I think the lesson here is
352
00:16:27,263 --> 00:16:31,201
don't drive around with
a 25% charged electric car.
353
00:16:31,201 --> 00:16:33,303
So this myth is confirmed.
354
00:16:33,303 --> 00:16:36,772
All right, um, I'm taking
the gas powered car
back to the shop.
355
00:16:36,772 --> 00:16:38,608
Yeah, I'll join you with that.
356
00:16:38,608 --> 00:16:40,810
Fay. You're about technology.
You suppose to come with me?
357
00:16:40,810 --> 00:16:43,679
Hey, it's gonna take you twice
as long to charge this thing
358
00:16:43,679 --> 00:16:45,014
- and I'm hungry.
- I just need ten minutes.
359
00:16:45,014 --> 00:16:46,816
Oh, my--
Just tell me an answer.
360
00:16:47,683 --> 00:16:49,685
Call us if you need any help.
361
00:16:49,685 --> 00:16:50,720
Ha-ha-ha.
