- [Narrator] With the all-new 2022 Tundra,
Toyota's legendary truck expertise
has entered a whole new generation.
Designed and assembled in the US,
this incredible truck rewrites the book
on what a full-size pickup can be -
and this three-part video series will explain how
through a closer look at the amazing engineering
that powers Tundra.
In this video,
we'll answer the top question on everyone's mind:
What's under the hood?
(orchestral music)
It may share the same i-Force name,
but Tundra's new engine is light years ahead
of the previous 5.7-liter V8.
This all-new 3.5-liter V6 is not only more efficient,
but more powerful as well.
It's all thanks to a new turbocharged design.
Put simply,
turbocharging uses a process called forced induction,
which basically involves adding a compressor fan
that enables the engine to take in much more air
and fuel than it would naturally,
giving it an on-demand ability
to effectively become "bigger" than it really is.
Through this, we can get power output like a big V8
when it's needed, and the efficiency of a regular V6
when it's not.
In its core configuration,
this engine can produce 389 horsepower
and a whopping 479 pound-feet of torque.
More importantly, however,
is that this new mountain of torque also occurs much lower
in the power band -
with a flat torque curve that has peak torque coming in
at just 2400 rpm.
This low-end grunt makes it vastly more usable
for both everyday driving and heavy-duty situations,
since the engine doesn't need to be revved up to redline
to deliver its full power.
Part of the reason Tundra's turbochargers
can perform like this is thanks
to their electric wastegate system.
Wastegate valves are what determine
the turbochargers behavior,
and this electric design allows for precise operation
that ensures optimum responsiveness, power and efficiency,
whether the vehicle is starting up,
cruising under low load, or at maximum acceleration.

Naturally, a pair of high-tech turbochargers
isn't all this engine has to offer.
With an engine this advanced, cooling is everything.
Up on top of the engine,
there's a water-cooled intercooler system,
which uses radiators on either side of the primary radiator
to cool airflow and improve turbocharger performance.
Similarly, a water-cooled exhaust manifold is integrated
into the cylinder heads to help keep engine temperatures
under control,
as does an electronically controlled fan coupler.
Meanwhile,
a new D-4ST dual-injection fuel system
further enhances efficiency by using both direct
and port injection methods to handle fuel going in,
while a pair of catalytic converters mounted immediately
after each turbocharger helps manage exhaust gas emissions
as it comes out,
and even the piston structure itself has been redesigned
to reduce friction and improve longevity.
Naturally, performance and efficiency are kept in mind
for the engine itself,
which can be seen in the lightweight design
of key components like the hollow camshafts
and the aluminum diecast cylinder heads.
All told, this is one seriously advanced engine.
(upbeat music)
But what if that wasn't enough?
Well then, meet Toyota's first i-Force MAX.
It builds on the amazing i-Force engine
by adding an all-new hybrid electric power system.
But this is no hybrid vehicle as you know it -
this one-motor hybrid system is designed not just
for efficiency - but also power.
By adding a healthy helping of electric torque into the mix,
i-Force MAX puts Tundra's power output
into the stratosphere.
Ready for the numbers?
437 horsepower and 583 pound-feet of torque.
And yes, it's still served up at that perfect low-rpm range
for incredible usability and acceleration.
Plus,
thanks to the electric motor's immediate torque response,
there's no discernible "lag" as the turbochargers spool up,
so all that power feels instantaneous.
The icing on the cake is that, yes, it's a hybrid,
so efficiency figures are also incredible.
And don't forget,
that efficiency comes from the same powertrain
that also makes nearly 600 pound-feet of torque.
Again, this is a completely different design
from previous Toyota hybrids,
a parallel hybrid system with a motor/generator
and clutch located between the engine
and standard torque-converting automatic transmission.
Even the hybrid battery design is enhanced,
located under the rear seat
and featuring a comprehensive cooling system
that optimizes durability and cabin comfort.
But ultimately, this entire system is designed to deliver
that perfect balance of refinement, power, and efficiency
in any situation, whether that's pulling a boat up a hill,
or circling the parking lot using only the electric motor.

So that's a quick look at some of the thought
that went into design the all-new Tundra powertrains.
And its amazing design can be found
under the hood of every model,
whether it's an i-Force in Tundra SR5
or the mountain-moving i-Force MAX available on Limited,
Platinum, and 1794 - and standard on TRD Pro.
This careful approach to design is a big reason
why Toyota has the reputation it does
when it comes to delivering quality, durability,
and reliability.
These are truly trucks built for the long haul,
wherever that may lead.
Now combine that with ownership perks
like the ToyotaCare Maintenance Plan
with Roadside Assistance,
and it's obvious why owners swear by their Toyotas.
In the following video,
we'll take a look at the rest of Tundra's drivetrain,
including its ten-speed automatic transmission,
its available part-time four-wheel drive system,
and its range of available driving assistance features.
