(car engine revs)
- This Rezvani Tank is 1000 horsepower,
street legal,
apocalypse-ready truck that has some absurd features.
It's bulletproof, it's got night vision,
it even has electrified door handles.
(electricity crackles)
But, it's got a whole lot more,
and today we're gonna look at some of those wild features
and the engineering behind them.
(upbeat music)
Thanks to Keeps for sponsoring
this episode of Bumper to Bumper.

some form of male pattern baldness
by the time they're 35.
Now if you still have hair
and you're worried about losing it,
prevention is key.
Now, Keeps treatments really work
to help it stay there
and the sooner you start using it,
the more hair you'll save.
You've gotta save all this hair.
Oh, I love you, hair, stay there!
We'll see if that works. (laughs)
One of the great things about Keeps
is you can visit a doctor online
and get hair loss medication
delivered right to your front door every three months.

Thank you, guys, so much for supporting the companies
that support us here at Donut,
we love you.
Rezvani Motors has been around since 2014,
designing and manufacturing custom cars.
You may have heard about them
when they hit the scene with their Rezvani Beast,
an Ariel Atom disguised as a super-car.
Well, they have now moved into the truck-making game
with the world's most sophisticated doomsday truck,
the Tank.
(upbeat music)
Now, the tank is a military-inspired,
extreme utility vehicle that, believe it or not,
started off as a Jeep Wrangler,
and Rezvani takes the base Jeep Wrangler,
strips it down
and builds it back up to what you see here.
But this thing is far from your standard Wrangler.
In fact, the frame is the only remaining part left.
So, let's jump in with the first feature
that makes it so different from its Jeep pen,
and that's that it's bulletproof.
(upbeat music)
Now, bulletproofing a car is nothing new.
Notorious gangster Al Capone
had his Cadillac fitted
with one inch thick bulletproof glass
all the way back in 1928.
So what makes this glass different?
Well, first is the type of glass.
This is glass-clad polycarbonate.
Now unlike Al Capone's Caddy,
which just used really thick standard glass,
this glass is a laminate,
and laminate is just the science equivalent of a lasagna.
You have your multiple layers of glass,
those are the noodles,
and then you have your inner layers of various plastic,
that's the red sauce,
and then you have a final layer of polycarbonate,
and that prevents all the shards of glass
and plastic from splintering off
and hitting you in the face,
that is the cheese.
Now regardless of the type of glass,
they all work in a similar way.
When a bullet hits the glass,
the energy spreads out throughout the layers.
The layers absorb the energy over a large area,
slowing the bullet down to the point
where it doesn't have enough energy
to penetrate through the entire sheet.
And there are different classifications
of bulletproof glass,
depending on the mass of the bullet
and the velocity that it's traveling.
There are nine different ballistic classes
to be precise,
from level one, which can stop shots from a 22 rifle,
to BR2, which can withstand a 357 handgun blast,
all the way up to SG2,
which can take three direct shotgun blasts
from a 12 gauge shotgun.
Now this Tank uses B7 rated glass,
the highest rating for a long rifle,
which is capable of withstanding a 9.8 gram AK47 round
10 meters away at 820 meters a second.
Fun fact:
Tesla actually uses their own simplified version
of bulletproof ratings
for their glass on the Cybertruck.
It's pretty easy,
it's can it withstand the impact
of a metal ball being thrown by a hipster
or can't it?
(metal ball hits glass)
- Oh my-- (cheering)
- Cybertruck burn!
I frickin' want one though.
I pre-ordered, they got $100 from me,
so can't make fun of 'em too much.
(laughs)
But what if someone decides to not shoot at the glass
but at any other part of the truck?
Well, the military edition uses ballistic armor,
it's capable of deflecting bomb shrapnel
and sniper rifles firing armor-piercing rounds.
To do this, the Tank adds roughly 4000 pounds
of added protection using steels.
But not all steels are the same.
The Tank uses hardened blast protective steel,
and hardened steel uses iron
and carbon in various amounts
that give it its blast-proof properties.
And if that isn't enough protection,
Rezvani uses Kevlar around critical components
like the radiator
and the fuel tank.
And the fuel tank is even self-sealing.
You have an inner liner,
which is usually vulcanized rubber,
which is unaffected by the fuel in the tank.
It's called vulcanized
because the rubber goes through a process
called vulcanization.
If you wanna know about that, good,
because I'm about to tell you.
Now, in 1839 this self-taught chemist
by the name of Charles Goodyear
was messing around with natural rubber,
trying to alter its properties
so that it would become a more useful material.
Like all great scientists,
he just made a mistake one day during an experiment,
he spilled a rubber-sulfur mixture on a hot stove
and instead of turning into goo,
it formed a stronger rubber.
He had created vulcanized rubber.
And when you heat up sulfur,
the atomic structure breaks apart,
and when you add in all the polymer chains of the rubber,
it bonds those chains together
and they become cross-linked,
and when that happens,
it improves the rubber's strength and elasticity,
and elasticity is just the ability
for something to go back to normal shape
after it's been stretched or compressed.
Now, it's not as easy as just mixing sulfur
and natural rubber
and then throwing it in the oven.
Goodyear spent years optimizing
the amounts of each substance, the temperature,
and the time.
By the way, this is years before Goodyear Tires was formed.
But the company is named in honor of him,
fun little fact.
Now, the layer outside of this vulcanized rubber
is a layer of untreated natural rubber.
Natural rubber comes from trees in the form of liquid latex,
it's basically white, sticky tree-juice.
Mm.
And we extract it from the tree in a similar process
to how we get maple syrup from trees,
the rubber gets withdrawn from the tree
by making cuts in the bark
and where the sticky rubber then drips down into a bucket.
It's called tapping.
Now, if a bullet were to somehow
get through the Kevlar-wrapped tank
and puncture it,
this is where the natural rubber works its magic.
When the fuel begins to leak out of that hole,
it comes in contact with that second layer
of untreated natural rubber,
and that rubber swells
and it gets sticky
and it expands, sealing the hole
and stopping the leak.
Pretty freakin' smart.
Speaking of rubber, why don't we talk about these wheels?
(upbeat music)
They have military run flat tires mounted on them.
So civilian-style run flat tires
have a reinforced sidewall,
which means if you puncture your tire
and it loses air,
the sidewall is strong enough
that you can still drive on them.
The tires stay rigid without any air pressure.
But military run flats, on the other hand,
they use a hard polymer insert inside the tire,
a run flat ring.
Now, these rings can withstand
the weight of an armored vehicle.
Remember, this Tank weights 6500 pounds,
so if the tires get shot up,
it can keep on rolling.
Baby.
♪ Oh oh oh ♪
♪ Oh oh ♪
So the Tank is bulletproof, it's blast-proof,
it's bomb-proof.
But is it EMP proof?
Now, for all my non-Modern Warfare Two buffs,
EMP stands for Electro Magnetic Pulse.
Basically, an EMP creates surges of voltage
and current inside electronics,
and that's bad,
it causes all the microchips
and circuitry to burn out,
and considering cars these days
are basically just big robot computer,
during an EMP strike,
it turns your car
or truck into an inoperable pile of steel.
So what causes EMPs?
Well, lightning strikes
and nuclear bombs.
Now, those aren't the only ways
but the two people worry about the most.
And for the builders of this car,
they were taking into account an EMP strike
from a nuclear bomb.
Now, the Tank uses the world's first EMP protection
for the entire electrical system.
It uses radioactively-charged gases
that help shield the initial strike of electricity
in 500 trillionths of a second.
To give you an idea how fast that is,
let's go back to 1995
and the closest finish in NASCAR truck-racing history.
- [Announcer] He pushed the fender
right in the door of Butch Miller.
Here they come out of four,
side by side,
to the line and--
- At the 11th race of the season
at Colorado National Speedway,
Butch Miller beat out Mike Skinner,
two dudes with sweet-ass names,
by one one thousandth of a second.
That's 0.001.
So how can we equate that amount of time
into distance,
a measurement that's easier for our brains to comprehend?
How far behind was the second place truck
when it crossed the line 0.0001 seconds later?
Well, to make the math easy,
let's just assume both trucks
were going 100 miles an hour
when the first truck crossed the line,
which is 146 feet per second.
Well, in one one thousandth of a second,
Butch's truck crossed the line 0.146 feet
ahead of Skinner's truck,
which is only 1.76 inches.
Like this,
that's how much he beat him by.
Now let's say Butch won by one 500 trillionths of a second,
how close would the two trucks be then?
And it turns out he would only win by .00000000035 inches
or 3.5 times 10 to the minus 10 inches.
We're talking Ant-Man
going down where you need an electron microscope
to even see stuff.
So I hope that helps.
Now, you can't call it a tank
unless it looks like a frickin' tank.
(upbeat music)
(siren wails) The sharp edges
and the larger fenders are by design.
One, because you need that space
to add in all the extra protective equipment
that comes in the Tank.
And two, because it just looks mean.
The front bumper, for example, is a ram bumper.
It's designed literally to ram (beep).
It's just a big hunkin' piece of steel.
There's also some cameras
and special lights in the front of the Tank.
You have your regular headlights
and next to them are blinding lights,
and they're meant to blind attackers
coming at you from the front.
Now, there are also a set of strobe lights
and they have one main function,
and that's to disorient potential enemies
who are prone to seizures.
(laughs)
That's so (beep) up.
(laughs)
There's also a sensor right next to it
and that's not your typical, everyday car sensor.
Because this Tank has radar.
Now, Rezvani uses FLIR thermal night vision,
and the word "FLIR" is a US military acronym
that stands for Forward Looking Infrared Radar,
and it detects thermal energy or heat.
Side note: these systems work
by detecting differences in heat.
So if you ever wanna try to trick the radar,
just try to match the temperature
of your surrounding area.
But given the sensitivity of this device,
that might be hard to do.
They can measure temperatures
down to a fraction of a degree fahrenheit.
But one thing they can't detect
is what's underwater.
So just jump into a pool,
if you're getting chased by the cops
using an infrared system on their helicopter.
It's a little Southern pro tip
from your bro bro Cousin Jerry.
Now, the radar on this Tank
is just one of the James Bond, MI6-inspired features
that add to this being the craziest, apocalyptic vehicle
you could ever get your hands on.
But, it's not the last one.
And inside there are even more gadgets to help save you
from the outside world.
(upbeat music)
Now, while the exterior looks very tank-esque,
the inside is cush.
It retains the interior layout of the Wrangler.
The seats are leather-wrapped,
as well as the door panels, the console
and the instrument cluster.
A $7500 option.
And if you take a look up,
you can see what $6000 gets you,
that's the starry night headliner,
like in a Rolls Royce.
Because, you know, if you're on lockdown inside your tank,
you need to be able to look up at the night sky
and not feel claustrophobic.
Ugh.
I don't like that feeling.
(laughs)
Now, there are a few main things inside here
that I wanna talk about,
and the first is the panel of switches.
The first switch I'm gonna talk about
is the electrified door handle switch.
Ooh!
Now, you flip this switch on
and a power inverter converts the 12 volt battery voltage
into a 120 volts of electricity,
charging the exterior handles,
and if anyone tries to open the door,
they get zapped.
Now, you might be thinking,
that's not a lot of voltage.
Well, you'd be right.
I mean, a TASER gun, for example,
has 30,000 to 50,000 volts.
But those are powered by smaller batteries
with very little current,
and it's the current that can actually kill you.
Now, current is the rate of flow of electrical charge,
and think of it as the amount of electricity
that passes by a point per second.
Now voltage, on the other hand, is the pushing force
of that current.
If you think of the river with water flowing down it,
the slope of the river is the voltage,
and the steeper it is,
the more pressure it exerts down on the water
at the end of the river.
Now the current is how much water is flowing
along that river per second.
Now, going back to our current kill saying,
a few drops of water running down a very steep river
carries far less energy than a big (beep) river
with a lot of water
flowing down only a slightly sloping river.
Now imagine you standing under a waterfall,
under those two rivers.
Now, you'd be soaked under the one with the larger current,
and it's current that damages the cells in your body,
it only takes something like 50 milliamps of current
to pass through your heart
and cause cardiac arrest.
And a car battery is a great source
for delivering a lot of current in short bursts.
Starter motors require a lot of current to run
and lead-acid batteries are good at providing
those necessary, intense bursts of current.
Now, if you look at your car battery,
it'll usually have a number
stamped next to the letters CCA,
and CCA stands for Cold Cranking Amps,
and that's the number of amps
or current a 12 volt battery can deliver
at zero degree fahrenheit for 30 seconds
while maintaining a voltage of at least 7.2 volts.
So, while a car battery doesn't have much voltage,
it has a lot of current,
and this system takes that voltage,
it steps it up to 120 volts
and takes advantage of all that current
and it shocks the (beep) out of any unwanted people
trying to get into your Tank.
Next to the electrified door handle switch
is another James Bond-esque feature.
You get a smoke screen,
and yes, it does exactly what you expect.
(car engine revs loudly)
Using a smoke generator,
which I didn't even know that was a thing,
the machine heats a volatile material,
typically some sort of oil,
hot enough to evaporate it.
It then mixes that oil vapor with the outside air,
which is cooler,
and it condenses, turning into smoke.
It's then shot out the back of the Tank
and it shields you from any enemy fire
that might be behind you.
Pretty cool.
And next to that, we have the dead bolts switch.
Turn that on
and four magnetic dead bolts lock you into place.
You've got an intercom system here,
which is pretty cool,
a variety of sirens to play, (siren wails)
and my favorite feature:
road tacks.
Say you've...
driven down to Mexico to bust your wife
out of a drug lord's underground jail cell,
you did the impossible,
you infiltrated their secure facility
and you got her out
and into the safety of your Rezvani Tank.
But the drug lord and his lackeys,
they aren't gonna give up,
so they start chasing you
and they're firing all their AK47 rounds.
Bam bam bam!
And you activate your smokescreen
to get some distance between you and them
as you navigate the narrow roads of Los Cabos.
But they're relentless
and they want your wife
and they don't care what the cost is.
And you're starting to think to yourself,
was this worth it?
You told her not to go to that bachelorette party,
you said,
""Remember when I asked isn't that place dangerous?"
and you said, "No, not at all,
as long as you stay on the resort."
And then remember when I said,
"Well, are you planning on staying at the resort?"
and you said, "I think I have a few day trips planned."
And then, remember when I said,
"Well then, I guess it's not really safe then, is it?
And you told me to stop being such a worrywart.
You remember that, Teresa?
Do you remember that (beep) Teresa?"
Bullets are still flying
and Teresa starts in with waterworks.
You've absolutely had it,
you're ready to get back home
and watch episode seven of Tiger King,
so you hit the tack switch
and a hundred three inch long sharp (beep) little tacks
get dropped out the back,
and those drug bozos behind you run 'em over.
Three hours later, you're back in L.A. on the couch
and Teresa's on the phone with Betsy
talking about their trip to Cape Town, South Africa,
and you're watching Joe Exotic be (beeps) awesome.
(laughs)
Okay.
Anyways, you have all these cool gadgets
that wouldn't really matter unless you had an engine
with enough power to propel this 6500 pound truck
down the road,
and doing the job of that
is the 1000 horsepower Dodge Demon engine.
A 6.2 liter supercharged V8
making a thousand horsepower in 870 foot pounds of torque
Now, Rezvani has a custom tune
and a smaller supercharger pulley
to bump it up from the standard 840 horsepower Demon motor.
Now, last week we talked about Speed Corp
getting more power out of the Demon egine
by going twin turbos,
ditching the factory supercharger.
Well, the Rezvani team chose to keep that supercharger
and massage more power out of it.
With the supercharger,
one of the ways to increase power
is to increase the amount of boost.
When I say boost, I really mean air mass,
not air pressure.
So you can increase power
by increasing the total amount of air going into the engine,
and more air into the engine
means we can put more fuel into the engine,
and if we use our very favorite Donut equation
of more air plus more fuel,
we get more power.
And one of the simplest ways to do that with a supercharger
is to increase the speed of that supercharger,
and you can do that by swapping out the lower pulley
for a larger one
or the upper pulley for a smaller one.
Either one of these methods
causes the supercharger to spin faster,
which then increases the amount of air
the supercharger pulls in.
Now that you have more air,
you can tune your fuel system
to increase the amount of fuel
and now you have more horsepower.
And in the case of the Tank,
you get 160 more horsepower.
The Rezvani Tank is an insane apocalypse-ready truck
that's close to half a million dollars.
If you have one of these,
I'm guessing you're working in a profession
where you need this level of protection.
I mean, Chris Brown has one
and that makes sense. (laughs)
We can't end on that.
(laughs)
