Difference Between Mazda 3 and Mazda 6

Mazda 3 vs. Mazda 6

Among the many types of cars from Mazda, the Mazda 3 and Mazda 6 are probably the most popular among ordinary buyers. The main difference between the Mazda 3 and the Mazda 6 is their classification and size. While the Mazda 6 is a midsize car, the Mazda 3 is compact, which means the Mazda 3 is slightly smaller than the Mazda 6.

It may not be very apparent when looking at the front of the cars, as the Mazda 6 is only 3 inches wider than the Mazda 3, but the 13-inch difference in length would leave no doubt as to which car is bigger. This difference is very apparent with the volume you get inside the car. The interior of the Mazda 6 has an additional 7 cubic feet of space, which translates directly into more headroom, shoulder room, hip room, and legroom. The size difference is also reflected in trunk space because the Mazda 6 has approximately 5 cubic feet of additional trunk space. And even the Mazda 6’s fuel tank is bigger. About 3 gallons of extra fuel capacity is really good for those long drives.

Everything really is bigger with the Mazda 6, including the engine. Engine options for the Mazda 6 only include 2.0L and 2.5L 4-cylinder engines. In contrast, you can get a 2.5L 5 4 cylinder engine with the Mazda 6 or you can get a 3.7L V6. Both options for the Mazda 6 offer much more power than their counterparts. Even when you compare both 2.5-liter engines, the Mazda 6’s engine may put out a bit more.

Surprisingly, the Mazda 6 can achieve better fuel mileage over the Mazda 3. Comparing the fuel mileage of 2.5L models, the Mazda 6 can get 21 cities and 30 highways, while the Mazda 3 can only manage 20 and 28 respectively. Of course, you’ll get better mileage if you go with the smaller Mazda 3 engine or worse, if you get the larger V6 engine from the Mazda 6.
