Is the 2022 Toyota Tundra Going to Get a Diesel Engine?

As 2021 is almost nearing its end, while and we’re preparing to welcome another new calendar year 2022, there will also be a lot of new changes being made in automobile manufacturing. For one, it seems most car manufacturing companies that also develop engines are now looking forward to introducing diesel engines, which will replace the long-adopted petrol (gasoline) engines in several hundreds of consumer and commercial vehicles that are still used today. In diesel vs petrol engines, diesel engines are longer last & efficient.

Likewise, the all-new 2022 Toyota Tundra pickup is rumored to get a diesel engine, says the Japanese automobile manufacturing company. The off-road compact pickup truck will also get new designs and looks, color options (which will vary with models and prices), accessories, and most importantly, an internal combustion engine for power.

Here, we will take an in-depth look at the next-generation Tundra diesel pickup from Toyota and share with you insights about this new consumer off-road truck for heavy-duty work.

Highlights of 2022 Toyota Tundra TRD Sport

Toyota’s new model of the 2022 Tundra off-road compact pickup truck will now be powered by a diesel engine, instead of a petrol (gasoline) engine. However, the release date of the new Tundra model has not yet been disclosed by the company, but it is speculated that many fans of compact off-road pickups will be greeted with a surprise.

Let’s now look at the engine specifications of the 2022 Tundra diesel model.

Power Under the Bonnet

The upcoming third-generation Tundra pickup 2022 diesel model is going to get two variants of the i-FORCE 3.5L V6 engine. One of the variants is the i-FORCE MAX Powertrain hybrid engine (electric motor), while the other is the fuel-only powered i-FORCE Twin-Turbo engine. However, both engine variants will get a 10-speed AWR10L65 “ECTi Direct Shift” automatic transmission system. The electric motor is placed between the engine & transmission that allowing more power to be transferred efficiently without causing any lag. Whether it is about charging up the trail or merging onto the freeway, the moment you drive this next-gen compact truck, you’d feel the instantaneous torque across the power-band, and you’ll be ready to keep the adventurous driving simply going.

The i-FORCE MAX Powertrain is an electrified hybrid engine model which can deliver power up to 437 HP and torque up to 583 lb-ft. On the other hand, the i-FORCE is a twin-turbo V6 engine model which will have a bit less power, up to 389 HP, and torque up to 479 lb-ft.

It appears that Toyota is upgrading its i-FORCE Max engine that is currently powered by a 5.7L V8. Their documents include a reference to a “compressed self-ignition type internal combustion engine”. However, this ignition system could apply to a diesel-cycle engine or an HCCI (homogenous charge compression ignition) engine that runs on petrol (gasoline) or diesel. The documents also frequently mention a “glow plug”, but these may only appear to be pieces that are used to heat fuel rather than air as they do in a conventional diesel engine.

Although no indications could be found whether there is a spark plug or not. Or, if there is a conventional glow plug in the accompanying line drawings, and the only materials named are an aluminum head with some chromium steel hardening points. A sketch of the engine’s model does show a couple of arrangements, one with ducts fitted to the chamber side of the cylinder head. And depending on the assembly it could be a part of the injector that inserts from the chamber side. And another that depicts ducts inside the head in the roof of the chamber.

In one section, the fuel is injected at a compressible charge, which is more indicative of a diesel engine wherein the combustion takes place when there is fuel fed to the engine. Now, this process is not the same concerning an HCCI petrol (gasoline) engine. In this process, fuel is injected during the intake stroke and then starts to combust impromptu when compression drives the temperature and density is quite high enough. However, in the past, HCCI has been tested on diesel fuel. Hence, Toyota may configure a way to make that workable over a wider sense in both speed and scope of load.

The other section frequently mentions the suppression of smoke. Smoke is usually made as a reference to diesel engines and that are rich-tune hot rods. However, that will not guarantee that both diesel and particulate matter doesn’t either. In Europe, many cars that run on petrol (gasoline)-fuel power have particulate traps, the majority of them having a direct fuel-injection system.

Is Having a Diesel Engine Worth the Choice?

The pre-heated fuel mixed with air causes an automatic ignition within the combustion chamber. It eliminates the need for spark plugs, reduces emissions, and improves fuel economy. The Toyota needs tight controls on blocking the temperature & other factors to make such engine work.

A quite fascinating application of this method is in a diesel engine though. This engine would eliminate one of the after-treatment systems currently on a diesel engine. As of now, you may have to add diesel exhaust fluid, then go through a regent process and replace your diesel particulate filters as well as keep an eye on your injectors. As many may see it, the diesel engine has been gutted by emissions equipment and is now a very costly engine to maintain. So, eliminating just one of those after-treatment systems would allow for reduced costs to purchase. Also, it could help in reduced maintenance, better fuel economy through reducing unspent fuel as well as possibly improving performance by eliminating one of the airflow restrictions off the engine. In other words, we could see a Toyota Tundra diesel engine that is more superior to petrol (gas), more efficient to operate, and less costly to buy.

How Much Will 2022 Tundra cost?

The price of the 2022 Toyota Tundra diesel engine model pickups will start from $35,950.


Toyota is going to use the V6 diesel engine for both the rear-wheel-drive and four-wheel-drive models of their new 2022 Tundra pickup trucks. Having a high-compression engine that will run on diesel fuel could bring a new turn in the US in the years to come.
