How much does a car engine weigh? How heavy is a V6 engine?

How much does a car engine weigh? If you are someone who likes to work on your car, whether it is to save money or for fun, you most likely have a pretty good idea about what you can and can’t do.

Oil change? No problem. Minor repairs? No problem. Taking out the engine altogether? That’s just not going to happen. A car engine weighs so much you haven’t got a hope of moving it without some heavy machinery.

Even if you have the knowledge and know-how, you may need to leave it to someone who does have the required machinery to take care of it for you. But how much does a car engine weigh and why? This article has all the answers.

How much does a car engine weigh?

Most large engines, such as V8s, weigh between 400 and 700 pounds, whereas a smaller V6 engine typically weighs between 300 and 450 pounds. The average automotive engine weighs between 300 and 700 pounds (140 to 320 kg). Diesel engines, on the other hand, can weigh more than 700 pounds.

Two-Cylinder Engine

A combustion system containing just two cylinders might sound strange nowadays. Nonetheless, this kind of engine usually weighs 165-220 lbs. Cars like the Volkswagen XL Sport, the 2014 Alfa Romeo Mito, and the Honda N600 have 2-cylinder engines.

Three-Cylinder Engine

A three-cylinder engine can weigh between 145-240 lbs., similar to two-cylinder variants. However, Ford produced an 88-pound, 3-cylinder, 400-hp tiny turbocharged Ecoboost engine. Nissan’s Batmobilesque ZEOD RC uses this propulsion machine.

Four-Cylinder Engine

A four-cylinder aluminum block engine will weigh 200 to 350 lbs. If it’s a cast-iron variant, expect it to be heavier.

Five-Cylinder Engine

Typical 5-cylinder engines weigh 300 to 350 lbs. European products like Audi and Volvo have five-cylinder engines.

Six-Cylinder Engine

Six-cylinder engines usually measure 450 lbs. or less. Minivans, sedans, and SUVs usually have six-cylinder engines.

Eight (and Above) Cylinder Engine

The average eight-cylinder engine weighs between 400 lbs. and 700 lbs. Higher-end luxury vehicles and sports cars have this kind of combustion system. Furthermore, 10 and 12-cylinder engines weigh more than 800 lbs.

Diesel vs. Gasoline Engine Weight

Typically, Diesel engines are heavier than their gasoline counterparts. They work based on the principle of compression ignition. The combustion process within a gasoline engine is smooth and controlled compared to that of a diesel engine. Diesel-powered systems need a dense and robust structure to cope with noise and vibration.

Consequently, diesel engines have a high compression ratio (usually twice that of gas engines). Therefore, to sustain this pressure, they need a very thick and heavy block.

Also, note that diesel fuel has larger and denser molecules compared to gas. A gallon of gasoline weighs 6.3 lbs. while that of diesel measures 7.1 lbs. Overall, this factor also contributes to the bulkier mass of diesel combustion systems.

How much does the engine in an electric car weigh?

Electric cars do still have an engine. It’s is just powered by electricity, not gasoline. Because the engine on an electric car is so much simpler than that of a gas-powered car, it can be much smaller and lighter.

The best example of an efficient electric car engine is the one used by Tesla. The Tesla Model S engine weighs just 90 pounds! You might think this makes the Tesla Model S very light. Which it does. Sort of. The battery needed to power the engine ends up making the car weigh a whole lot more.

How much does the battery weigh in an electric car?

Using Tesla as an example again, since they are the only people making a decent electric car, we can look at how much their batteries weigh.

Despite losing a lot of weight by eliminating gasoline and a heavy engine, Tesla’s end up weighing a huge amount more than the average car. A Tesla battery will weigh about 1200 pounds. Twice as much as even the biggest gasoline engine.

For comparison, a standard car battery weighs just 41 pounds. Of course, it has a lot less to do than the battery of a Tesla. But the difference is still both interesting and impressive. You could easily change the battery in your car, it takes very little knowhow and very little time. Changing the battery in a Tesla means taking the whole car apart.

How much does engine weight affect speed?

Engine weight does play a big part in speed. A heavier engine will cause a car to go slower. If you can find a way to get a better power output while reducing the weight of your engine, your car will go faster. The best evidence for this is again looking at Tesla.

The engine weighs 90 pounds but the car can go 155mph. 0-60 in less than 3 seconds. Because it gets its power from the battery. The best way to increase speed is by losing weight in other areas. This is why rally drivers take out the back seats of their cars.

Will the engine weight affect its performance?

The performance of a vehicle is not truly determined in absolute terms by engine weight. An improved performance estimator is the power-to-weight ratio.

However, lighter engines have a marginally better impact on performance. Vehicles that are lighter typically handle better and use less fuel.

So it shouldn’t be surprising that automakers are choosing lightweight materials for engine construction. Jaguar, for instance, favors the use of aluminum, whereas BMW is very interested in the manufacturing of carbon fiber.

Do Heavier Engines Last Longer?

There is no evidence that weightier engines last longer. Research hasn’t indicated any positive correlation between engine size and longevity. Your vehicle brand, maintenance culture, and driving habits have more effect on your engine’s lifespan.

For example, when comparing between three engines of Dodge – 5.7 Hemi, 6.4 Hemi, and 5.9 Magnum, both Hemi engines are lighter than Magnum one but they can last longer than the 5.9 Magnum.

Precision manufacturing and quality engineering also determine engine lifespan. Nevertheless, larger engines can do less work to produce significant energy due to their greater displacement. But bear in mind that a bigger internal combustion system has poorer fuel efficiency.

Also, you must match an engine in a proportionate manner to the vehicle you want to drive. If your engine size is too small for your vehicle, there will be less efficient power transmission.

The engine might have to work twice as hard to move your vehicle. If the reverse is the case, fuel efficiency won’t be good. However, Ford, a top-notch manufacturer uses turbocharging to release more power from smaller engines with optimized fuel consumption.

What are the factors affecting how much a car engine weigh?

How much does a car engine weigh

There are certainly different factors affecting how much a car engine weighs, including:

Size

The motor’s size will have the greatest impact on its weight. The number of cylinders of an automobile engine has determined its class. Under the hood of the majority of passenger cars is a four-cylinder engine.

Though six- or eight-cylinder engines, many of which are grouped in a V-shape layout, will be standard on larger cars. The weight increases along with each additional cylinder.

Model Year

The engine’s model year has an effect on weight as well. The likelihood of improvements increases with engine age. In some circumstances, these innovations can make the weight lighter. However, because more equipment is required as a result of new technology, the weight may also increase.

Material

The construction material is another factor that affects weight. Compared to an aluminum-made motor, a cast iron engine will be heavier. An older engine might be constructed of cast iron and hence weigh more than an engine found in a more recent model made of aluminum. Because of this, several car models lose weight as they age.

Displacement

The weight will also depend on engine displacement. For instance, due to the lesser displacement, the GM 215 cubic inch engine weighs around 175 pounds less than the LS1 346 cubic inch engine.

You can anticipate a heavier engine if the cylinder holes are larger and the pistons have to travel a greater distance. This justification suggests that a huge four-cylinder engine might weigh more than a small six-cylinder engine.
