Knowing the load of a vehicle engine once lifting it out of your vehicle can be interesting. Here is the typical weight that V6, V8 and also 4-cylinder auto engines and what come think about

Whether you room planning to replace your vehicle’s motor or you are simply curious, you can be asking yourself – how much does a auto engine weigh? with so many different engines ~ above the road, it’s an overwhelming to say that all motors weigh the very same amount.

Engine size is the largest aspect in weight, with most big engines choose V8s weighing in between 400 and 700 pounds and also a smaller V6 engine weighing between 300 come 450 pounds on average. However, diesel motors deserve to weigh more than 700 pounds.

We look at several types of engines and discuss how the load is determined. Ours article also determines if the engine size affects performance.

Factors Affecting car Engine Weight

1. Size

The dimension of the engine is walking to it is in the best determination the its weight. Automotive engines are classified through how many cylinders that has.

In many passenger cars, friend will find a four-cylinder engine in ~ the hood. However, bigger vehicles space going to it is in equipped through six- or eight-cylinder engines, many of which room arranged in a V-shape configuration. V each cylinder that’s added, more weight is tacked on as well.

2. Material

Another element determining the weight is the material used because that the construction. A actors iron engine is walk to it is in heavier 보다 a motor created from aluminum.

An larger engine can be make from cast iron, causing it to weigh much more than what’s uncovered in a newer design made from aluminum. It is why some automobile models weigh much less as they obtain newer.

3. Displacement

Engine displacement is likewise going to impact the weight. As an example, the GM 215 cubic inch engine weighs around 175 pounds less than the LS1 346 cubic customs engine because of the smaller sized displacement.

The larger the cylinder feet are and the additional the pistons need to travel, the an ext weight you have the right to expect. Therefore reasoning, a huge four-cylinder engine can weigh an ext than a compact six-cylinder motor.

4. Version Year

The model year that the engine likewise impacts weight. The more recent the engine is, the an ext likely breakthroughs were made.

In some cases, these advancements can lower the weight. However, brand-new technology can additionally lead come a higher weight as added equipment is needed.

Average V8 Engine Weight

The usual V8 engine weighs about 400 come 700 pounds (180 come 320 kg). In a large pickup or SUV, you will often find the most difficult V8 engines.

However, not all V8 engines are huge and heavy. In fact, both the Ford/Jaguar 3.9-liter V8 indigenous the 1990s and the GM 215 V8 were considered smaller eight-cylinder engines that weigh less than most.

Average V6 Engine Weight

The V6 engine looks similar to the V8 motor, but it contains two under cylinders, therefore you can expect the load to be reduced overall.

Most V6 engines will certainly weigh between 300 come 450 pounds (140 to 200 kg), but the same factors are in play.

Displacement no always change the weight dramatically. An example of this deserve to be seen v the Ford EcoBoost V6 engine. The 3.5-liter V6 engine weighs 449 pounds, contrasted to the 2.7-liter V6 that just goes under nine pounds even though the is smaller.

Average 4 cylinder engine weight

The average weight the a 4 cylinder modern-day aluminum automobile engine is 200 come 350 pounds (90 come 160 kg), quite much lighter 보다 a v6 or v8 engine. If it’s a cast-iron block you can expect it come be contempt heavier 보다 an aluminum engine.

Weight that Diesel vs. Gasoline Engine

The design of a diesel engine naturally makes that heavier 보다 a comparable gas motor. Diesel engines produce much more power 보다 the gas-powered variant, so it demands to be built differently. This included durability leader to much more weight.

Fun fact: Diesel fuel weighs an ext than gas since of the larger molecules. It additionally atomizes differently since of the viscosity and density. One gallon the diesel fuel weighs 7.1 pounds, while a pound of petrol only procedures 6.3 pounds.

Do more heavier Engines critical Longer?

Engine size won’t tell girlfriend the durability of the motor. Exactly how it is used and the vehicle it is put in will certainly have much more effect ~ above longevity than size.

Larger engines don’t occupational as tough as the smaller engine does, but it likewise contains more heavier parts, so much more fuel and also power is needed. A more heavier engine deserve to wear out just as quick as a lighter engine. However, the can additionally be an ext expensive come repair.

Engine weight vs. Performance

Years ago, that was for sure to assume that the bigger the engine was, the an ext power the output. However, that is no much longer the case.

Large engines are generally used in high-performance vehicles for far better speed and acceleration. However, these more heavier engines additionally reduce braking performance due to the fact that there is much more weight that should be stopped. Larger engines can also make that more difficult to readjust lanes and take turns.

Additionally, lighter engines can be more efficient. With a lower weight, less fuel is required to relocate the vehicle. It is why it’s necessary to evaluate the performance and also weight of one engine prior to deciding those best.
