How much does a car engine weigh when placed on a scale? The actual weight of a car engine is dependent on the design and style of the engine.

For example, a V8 engine may weigh more than a typical V6 engine because of the additional cylinders in the V8. Similarly, a 10-or -12 cylinder engine would weigh more than a V8 engine.

But generally, car engines weigh around 200lbs to 1200 lbs based on the design, number of cylinders, and other factors that may affect the engine’s weight.

In this article, we would consider the weight of various common types of car engine!

How Much Does a Car Engine Weigh?

Typically, diesel engines weigh higher than their gasoline counterparts. Also, it is important to understand that there are different factors that determine the weight of an engine.

Cars with the biggest/heaviest engine include the 1910 Fiat S76, SRT Viper, and Bugatti Veyron; there are other cars with heavy engines.

However, the heaviness of an engine does not mean the engine would perform better than a lighter one. What determines the efficiency and performance of an engine include the type of oil used in the engine, the torque capability, and pretty many other factors.

Notwithstanding, smaller engines such as 2-cylinder, 4-cylinder, and 6-cylinder engines weigh from 160lbs – 500lbs, while bigger engines from 8 cylinders to 12 cylinders, or more, weigh from 400lbs – 1000+lbs.

It is safe to assume that the number of cylinders in an engine can directly affect its overall weight on a scale. To better understand the weight of your car engine, we’d further break this down to discuss the weight of popular car engine types.

How Much Does a V6 Engine Weigh?

A typical V6 engine would weigh between 300 – 550 lbs; however, some V6 engines may weigh more than 550 lbs. The Chevy V6-90 229, 4.3L weighs 425 lbs, while the Chevrolet Citation Sedan 2.8 V6 weighs 2,491 lbs; as you can see, the difference is quite huge.

This proves the fact that the final weight of an engine is based on different factors, which are explained towards the end of this article. Vehicles with V6 engines typically include sedans, minivans, cars, and some SUV rides.

How Much Does a V8 Engine Weigh?

Place a V8 engine on a pounds scale and expect to see anything from 500 lbs to 800 lbs. V8 engines are found in trucks, pickup vans, and many other vehicles that are used for heavy-duty activities.

How Much Does a Truck Engine Weigh?

Most trucks drive with a V8 engine, but there are some that drive with 10-cylinder or 12-cylinder engines. The weight of truck engines falls between 600 lbs – 1200 lbs; this is just the average, some truck engines are much heavier and weigh up to 2000 lbs.

Again, the weight of an engine is based on different factors, including the number of pistons, cylinders, and other engine components.

How Much Does An Engine And Transmission Weigh?

Engines weigh from 200 – 1000 lbs and transmissions weigh from 100 lbs – 400 lbs depending on the vehicle type and purpose.

If you decide to put a transmission and an engine on the same scale, expect to see around 300 – 1500 lbs as the weight outcome, and this depends on the type of transmission and engine being put on the scale.

How Much Does a 4 Cylinder Engine Weigh?

4-cylinder engines are among the lightest engines you’d see out there and that’s because they are not sophisticated. In the same vein, they are the engines that output the lowest power, and as such, you’d find 4-cylinder engine is old vehicles.

Some new vehicles still come with V4 engines, but they are very few. The average weight of V4 engines is between 165 lbs to 250 lbs.

Car Engine Weight Chart

The table below shows the weight chart of different car engines:

Engine TypeWeight
4 cylinder165 – 250
6 cylinder300 – 550
8 cylinders500 – 1000
10 cylinders650 – 1200
12 cylinders700 – 1500

Factors that Affect Car Engine Weights

1. Engine Model

The engine model is also one of the factors to determine the weight of an engine. Newer engine models are typically lighter than older ones, thanks to newer auto technologies.

2. Material Used

Apparently, the material used in manufacturing an engine has a part to play in the engine’s weight. An engine made from cast iron would be heavier than an engine made from aluminum.

3. Number of Cylinders and Displacement

The more the number of cylinders in an engine, the heavier the engine would weigh. Also, the displacement of an engine would affect the weight. An engine with a smaller displacement would be lighter than an engine with higher displacement.


In conclusion, how much does a car engine weigh? The weight depends on the type of engine; on average, car engines weigh from 165 lbs to 1,200 lbs while transmissions weigh around 200 lbs on average.
