The Sentra is only a standard “Top Safety Pick” for 2018.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Kia vehicles are more reliable than Nissan vehicles. J.D. Power ranks Kia first in reliability, above the industry average. With 60 more problems per 100 vehicles, Nissan is ranked 20th.

On the EPA test cycle the Rio gets better mileage than the Sentra:

The Rio has standard front and rear gas-charged shocks for better control over choppy roads. The Sentra’s suspension doesn’t offer gas-charged shocks.

For better maneuverability, the Rio’s turning circle is 4.6 feet tighter than the Sentra’s (33.5 feet vs. 38.1 feet).

The Kia Rio may be more efficient, handle and accelerate better because it weighs about 250 to 300 pounds less than the Nissan Sentra.

The Rio Sedan is 10.1 inches shorter than the Sentra, making the Rio easier to handle, maneuver and park in tight spaces.

The Rio has a much larger trunk with its rear seat up than the Sentra (17.4 vs. 14.3 cubic feet).

The power windows standard on both the Rio and the Sentra have locks to prevent small children from operating them. When the lock on the Rio is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Sentra prevents the driver from operating the other windows just as it does the other passengers.

Consumer Reports rated the Rio’s headlight performance “Good,” a higher rating than the Sentra’s headlights, which were rated “Poor.”

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Rio’s available headlights were rated “Good” by the IIHS, while the Sentra’s headlights are rated “Acceptable” to “Poor.”

The Rio’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Nissan only offers heated mirrors on the Sentra SV/SR.

The Kia Rio comes in sedan and station wagon bodystyles; the Nissan Sentra isn’t available as a station wagon.

Insurance will cost less for the Rio owner. The Complete Car Cost Guide estimates that insurance for the Rio will cost $1020 to $1560 less than the Sentra over a five-year period.

The Rio will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Rio will retain 45.24% to 45.96% of its original price after five years, while the Sentra only retains 38.28% to 43.99%.

According to The Car Book by Jack Gillis, the Rio is less expensive to operate than the Sentra because typical repairs cost less on the Rio than the Sentra, including $46 less for a water pump, $11 less for front brake pads, $134 less for fuel injection, $180 less for a fuel pump, $142 less for a timing belt/chain and $17 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Kia Rio will be $4274 to $6491 less than for the Nissan Sentra.
