Comparison Review

Comfort
Passengers in the back seat will feel a little more squished in the Kia Rio than in the Mazda Mazda3, due to the Kia Rio's smaller rear head- and legroom. As far as headroom and legroom go, there's not much difference between the Kia Rio and the Mazda Mazda3 in the front seats.

Convenience
The Kia Rio will require fewer stops at the gas station than the Mazda Mazda3, making it more convenient to drive.

Cost
There are a lot of factors to consider when calculating the overall cost of a vehicle. The main consideration is Manufacturer's Suggested Retail Price (MSRP). Based on MSRP, the Kia Rio is clearly a better financial choice over the Mazda Mazda3. Another consideration is the Destination Charge, which is a standard charge for transporting the vehicle to the dealer from where it's built. The Kia Rio and the Mazda Mazda3 have similar Destination Charges.

Dimensions
Since the Kia Rio is much slimmer than the Mazda Mazda3, it'll be much easier to find a wide enough space in a crowded parking lot. If you go with the Kia Rio, you'll have a much easier time finding a large enough space to park than you will with the Mazda Mazda3.

Handling
The Kia Rio has a smaller turning radius than the Mazda Mazda3, allowing you to more easily maneuver in and out of tight spots.

Performance
When it comes to horsepower, the Kia Rio is significantly less powerful than the Mazda Mazda3. The good news is that, reportedly, cars with lower horsepower engines often have lower insurance premiums.

Powertrain
The Kia Rio has much less torque than the Mazda Mazda3, which generally means that it won't feel as fast or powerful.

Utility
In terms of seating you'll be able to fit the same number of people in both the Kia Rio and the Mazda Mazda3. The Kia Rio has significantly less cargo room than the Mazda Mazda3, which may be a concern if you do a lot of warehouse shopping.

Warranty
You'll have greater peace of mind with the more generous basic warranty of the Kia Rio than that of the Mazda Mazda3.
