5 Pickup Trucks That Do Not Have Spark Plugs | Why they don’t?

We may get commissions for purchases made through links in this post. Thanks for the support! 👍

There are a few pickup trucks on the market that do not have spark plugs. These vehicles either have a diesel engine or are electric vehicles, which means there is no need for spark plugs. In this article, we will discuss why these trucks do not have spark plugs and what benefits they offer consumers. Stay tuned to learn more!

Spark plugs are used on gas vehicles, so that means that vehicles that don’t use gas will not have spark plugs! That leaves trucks with diesel engines and electric vehicles like the trucks that don’t have spark plugs. This list includes a mixture of those!

It should be noted that I included mass-market pickups on this list such as the Ram 1500 and the GMC Sierra 1500 as examples, however, there are plenty of larger pickups like 2500 and 3500 series trucks that also have diesel engines and are not equipped with spark plugs.

1. 2022 Ram 1500 EcoDiesel

The 2022 Ram 1500 EcoDiesel one of the best bets for a workhorse pickup. With an impressive 33 highway MPG, this truck can help you get the job done without breaking the bank at the pump.

Plus, the available 3.0L EcoDiesel V6 engine provides plenty of power, while Active Air Grille Shutters keep things running quietly and efficiently. So if you’re looking for a tough and fuel-efficient pickup that won’t let you down, the Ram 1500 EcoDiesel is a perfect choice.

As this is a diesel pickup truck, it is also one of the main pickups on the market that don’t come equipped with spark plugs, and instead combustion happens by pressure, rather than ignition.

2. 2022 Rivian R1T

If you are wanting something a bit different than a diesel pickup truck, and a bit more acceleration, then an electric pickup is worth a look.

The 2022 Rivian R1T is more of a lifestyle pickup rather than a work truck. However with 835 horsepower and 908 lb-ft of torque, this pickup’s lifestyle is a massive amount of performance, and this vehicle can take you anywhere you want to go.

The battery capacity of 135 kWh gives you a range of up to 70 mpge, making it the perfect choice for long-distance driving.

As this pickup is an electric truck, it does not utilize combustion, and spark plugs are not needed!

3. 2022 GMC Sierra 3.0L Duramax Turbo-Diesel

The Turbo-Diesel GMC Sierra 1500 may not have the most amazing horsepower when compared to the competition, but it does have an incredible amount of torque for a 1500 series pickup.

With its 277 horsepower and 460 torque, this truck is sure to take on whatever you need it to – whether that’s heavy hauling or long-distance towing.

Plus, with its 10-speed automatic transmission and high-pressure common-rail direct injection system, this truck is as efficient as it is powerful.

4. 2022 Jeep Gladiator EcoDiesel 

With its 3.0-liter EcoDiesel V6, it puts out 260 horsepower and 442 pound-feet of torque, so you can tackle any job with ease. Plus, the 8-speed automatic transmission ensures smooth shifting and great performance on the road.

So if you’re looking for a truck that can handle anything, the Jeep Gladiator EcoDiesel is the one for you.

If you are wanting a diesel (which doesn’t have spark plugs), but also want to go off-roading, the Jeep Gladiator with the 3.0L Diesel is a fantastic option (and can be flat towed).

You will get that low end torque to get you out of off-road situations, and get the gas mileage on the pavement as well.

This truck can also benefit heavily with something like a DECKED bed system.

5. 2022 GMC Hummer EV

While the GMC Hummer EV truck may just now be delivering (at the time of this writing), it does offer some crazy specifications. Not to mention, in light of this article, it also does not have spark plugs due to its electric drivetrain.

This truck can go from 0-60 in just 3.5 seconds and has up to 1,000 horsepower. Plus, it comes with an exclusive GM lowering kit that gives you a 2″ advantage over the competition and enhances your center of gravity.

And if that’s not enough, the Hummer EV comes with a multi-sensory experience package that will make you feel like you’re driving in luxury.

Why wouldn’t a pickup truck have spark plugs?

There are two different reasons why pickup trucks may not have spark plugs!

The first, and historically the main reason why a truck wouldn’t have spark plugs, is because it uses a diesel engine. Diesel engines don’t have spark plugs, because they rely on compression to ignite the fuel-air mixture instead. These trucks instead use glow plugs, which heat up and help the engine start in cold weather.

The second reason is that an increasing number of pickup trucks are now electric vehicles. Electric vehicles don’t have spark plugs for a different reason; they don’t use combustion to power the engine, so there’s no need for spark plugs! Instead, they have electric motors at the wheels themselves that pull power from massive battery packs. Without the need for any combustion, spark plugs are not needed.

Why would you want a vehicle without spark plugs?

Diesel engines are more efficient than gasoline engines, so you’ll get better fuel economy with a truck that uses one. Electric vehicles also generally have more power than any combustion engine pickup can have.

On the other hand, spark plug vehicles have been the standard for the world for years, this means there has been tons of development on those vehicles, meaning that they have a trusted backing from that development.

Frequently Asked Questions

Why do diesel trucks last longer?

Diesel engines combust at a much lower temperature and work at a much lower heat and workload. This means that cylinder walls, among other things, are worn out at a much lesser rate than their gasoline counterparts. While diesel engines may be more expensive, they can last much longer and get you better gas mileage.

How can you tell if a truck is a diesel?

There are a few giveaways when it comes to identifying if a truck has a diesel engine. One giveaway is the sound – diesel engines tend to be much louder than gasoline engines, and have a “tick” that their counterparts don’t have. Another great way to tell if a truck is a diesel is to check behind the fuel door, this will show what gas (or diesel) is needed for that vehicle.

Why are electric trucks so fast?

Electric trucks have a ton of torque that is available from 0 RPMs. This means that they can get up to speed very quickly. Electric trucks also have very good traction because of the way that the weight is distributed in the vehicle.


In conclusion, there are a few reasons why pickup trucks may not have spark plugs. The first is that some trucks use diesel engines, which don’t need spark plugs to ignite the fuel. The second is that an increasing number of pickup trucks are now electric vehicles, which don’t use spark plugs because they have electric motors at the wheels themselves.

Whether you’re looking for a powerful diesel truck or an efficient electric one, there’s sure to be a pickup without spark plugs out there that meets your needs.
