How much does your car engine and transmission weigh?

Both engine and transmission play important roles powering your vehicle. Without them, all you would have is a stagnant vehicle frame. Because these parts are so important, it is necessary to regularly question issues surrounding them and how such issues influence the engines performance. One such issue is weight. Is a heavy engine okay? How heavy is too heavy for your combined engine and transmission weight?

General engine weight

On average, car engines weigh a total 350 pounds, that’s 158 kilograms. Depending on the type of engine, the weight could fluctuate between 300 pounds for a small engine or up to 600 pounds for a large one.

These weights are inclusive of the transmission. This number is influenced by several factors including the material used to construct the engine, cylinders on the engine, volume of the engine etc.

How you can reduce your car weight

Some people prefer to reduce their overall car weight by eliminating unnecessary parts. Research suggests that you will experience reduced car fuel consumption in every one hundred pounds shed from your overall car weight.

Additionally, reducing the weight engine saves you from having to change your tires to accommodate extra weight and have good traction. There are several ways you can reduce your overall car weight even with a heavy engine.

  • Drilling holes

This is an extreme resort for anyone who really wants to drop the total car weight. It is achieved by drilling holes in metal part. Consequentially, the vehicle becomes less rigid

  • Change the windows

Instead of glass windows, you can choose the lighter polycarbonate option.

  • Swap exterior parts

These contribute the largest part of weight savings. Because most of these exterior parts are made of metal substance, they are pretty heavy. You may opt to swap them out for a glass fiber plastic, which is way lighter. You can do this for your doors, bonnet roof or front wings

TIP: when you choose to go with polycarbonate and carbon fiber replacements, ensure you get the best possible quality to complement the rest of your vehicle.

The engine block

To a newbie, at first glance the engine block looks like a mould with a bunch of holes in it. It is an important part of the engine that comes with holes molded to correspond to the number of cylinders of the engine.

Because it commonly made of a blend of aluminum or iron, the engine block is quite a heavy engine part. It is basically a bed upon which several other components of the engine sit.

Common weight for a transmission

On average a transmission model weights typically between 100 to 400 pounds. The final weight is dependent on the make and the model of your vehicle. This is because big cars cannot rely on the same size transmission as a smaller model.

As you scale up car sizes, the weight and size of an appropriate transmission increases. Before we can look at the difference and significance of weight on transmissions, take a look at the types of transmissions available and their differences.

Automatic vs. Manual transmissions

From the heading, you can tell there are two types of transmissions. Manual transmissions that require more work to use compared to the automatic transmissions. Manual transmissions require you to use a clutch to physically shift the gears.

You will need to apply shift knob and clutch pedal to move forward and achieve higher speeds. Automatic transmissions on the other hand will make these gear changes, you need only push the gas pedal.

You must be wondering why anyone would choose a manual transmission with the convenience that comes with an automatic transmission. Well apart from the difference in control, there are other differences including fuel economy, control and price points that influence the decisions.

Unfortunately, an automatic transmission means greater fuel consumption. Additionally, manual transmissions offer more control however they are bothersome to use unlike automatic transmissions that promise comfort and convenience. Cost of purchase and maintenance for automatic transmissions supersedes that of manual transmissions.

Bonus CTV

This is t the third type of transmission available. Continuously variable transmissions rely on a bet-pulley system that provides infinite ratios. Meaning, the transmission never shifts. Some drivers find this concept bizarre but CTV equipped cars are comparatively smoother to drive and can improve gas mileage.

Final Word

Total engine and transmission weight evidently has an effect on performance and fuel economy. While there is nothing wrong with getting upgrades and fitting your car with the best engine available, you must consider the negative implications of having a heavy car.

At the very least, try and maintain your engine and transmission weights at recommended weight so as to avoid the extra expense that comes with running a heavier car. If not? The tips above should help you decrease your total car weight significantly.
