Difference Between Mazda 3s and Mazda 3i

The automotive industry, or in fact the entire mechanical engineering industry, is a very dynamic, diverse, and ever-changing one.

Every now and then, we see a new piece of technology, or equipment making its way to the market and eventually to the customers.

And not only that, a single piece of technology can be modified to present itself in different forms, and that is very widely seen in the subcategories different car models have under the same product line.

That is also valid for the Mazda 3 series. Here, we specifically talk about two cars, the Mazda 3s and the Mazda 3i.

The Mazda automotive company is a well-known car company based in Japan. They are well known to produce cars which are well suited for city travel, as well as some high performing ones. Their 3 series has two cars under it, the 3s and the 3i.

What is Mazda 3s?

The Mazda 3s is a more higher-end trim option of the Mazda 3 series. The 3 series has always been a very successful product line for the Mazda automotive company.

Since the 3s is a more expensive variant, hence it is easy to conclude that the 3s has way more features than the 3i, thus resulting in the price gap.

The 3s has a bigger engine, as well as more horsepower. However, it lacks in the mileage department. This is understandable since a bigger engine produces more power, which means more consumption of fuel.

The engine size of a standard Mazda 3s is 2.5 liters, which is capable of producing a total of 167 horsepower. 

It also has a 6-speed transmission. This means that the car operates using 6 gears within the transmission system. Each gear helps the car attain a certain speed, after which it shifts to a higher gear.

The more the number of gears, the faster is the car able to travel. This is understandable in the Mazda 3s, as it already has a large engine, and produces more horsepower.

As a result, it is obvious that the car will be able to travel at a higher speed than the less powerful models in the same product line.

Moving on from the engine and power output terms, there are other small areas where Mazda has given the 3s a significant upping as compared to the 3i.

The presence of side airbags in the 3s is one such example. The Mazda 3s has side airbags, while the 3i lacks any. This is a handy safety feature that might come in use in times of need. Another feature which the 3s has is keyless entry.

This is a very convenient feature, which is not necessary, but very useful. This comes to use especially when one is approaching the car with their hands holding bags full of different items, and cannot reach for their keys.

They can also open the boot space without using the keys. Needless to say, the start and stop are keyless too.

What is Mazda 3i?

The Mazda 3i is the more affordable version of the 3 series product line of the Mazda automotive company. When we say affordable, it is natural that it is a lower-end version when compared to the more expensive Mazda 3s.

However, when we say lower-end, we do not mean to imply that the car lacks in anything, or in any such way. One will find all necessities present and in fact, more than the necessities to be present too.

But, one will find a bit more features in the 3s that push it into the luxury segment, which brings about more convenience, and a price too.

The 3i has a smaller engine compared to the 3s, at only 2.0 liters, and produces only 148 horsepower. However, one big advantage of having a smaller engine is that the 3i gives better mileage as compared to the 3s.

This is because a smaller engine consumes produces lesser power, which means that it consumes lesser fuel and thus, making energy consumption efficient.

This is ideal in the case of small city travel or traveling to places where there might not be fuel stations for long distances.

The Mazda 3i also lacks AFLs, or Adaptive Front Lighting, which is when the headlights sway in motion with the turning car to help the driver get a better view of the road.

It also has 16-inch steel rims, which are relatively heavier compared to the aluminum rims present in the 3s.
