Deciding on a used car is tough. You have to pick a brand as well as the size of your car. There are a lot of options out there and it is tough to know which is best. That is why we are going to look at two of your car options. The used Nissan Sentra and used Nissan Altima are two different size cars, and we are going to look at the features of each, so you can decide which is best for you in this used car comparison.

Size Comparison

The Nissan Altima and the Nissan Sentra are not the same size car. These cars are slightly different, so a size comparison is an important one. The Nissan Altima is a mid-size sedan, while the Nissan Sentra is a compact sedan.

However, just because the Sentra is compact, doesn't mean it is short on space. This vehicle is well-proportioned to give you a spacious interior. The Altima is 191.5 inches long with front legroom of 45 inches, while the Sentra is 182.1 inches long with front legroom of 42.5 inches. That isn't too drastic of a difference, but the Altima does give you a bit more space. In overall passenger volume, the Altima also gives you slightly more with 102 cubic feet to the Sentra's 96 cubic feet.

Size is definitely an important thing to consider, but both of these vehicles give you a comfortable and spacious interior.

Performance Differences

The engine options and performance is another factor that is a little bit different between the 2015 Nissan Sentra and the 2015 Nissan Altima. Let's take a closer look at what is under the hood and see those differences.

The 2015 Nissan Altima comes with a 2.5-liter four-cylinder engine that gives you 182-horsepower and about 38 highway miles per gallon. The 2015 Nissan Sentra has a 1.8-liter four-cylinder engine standard. This engine gives you 130-horsepower and about 39 highway miles per gallon.

The Altima gives you more horsepower, but it is important to remember, the Altima is a bigger vehicle, so it has the bigger engine and more horsepower to accommodate for that. A very interesting statistic is the highway miles per gallon. These two vehicles have very similar numbers here, meaning that both vehicles use their engine power effectively and efficiently.

Interior and Available Options Comparison

In addition to the size and engine differences, there are also differences in some of the features of the 2015 Altima and Sentra. Let's take a closer look.

Both the Used 2015 Nissan Altima and the Used 2015 Nissan Sentra come standard with a four-speaker audio system and Bluetooth. However, some of the technology options differ slightly. The 2015 Nissan Altima can come with a 7-inch touchscreen with NissanConnect, while the 2015 Sentra only has an available 5.8-inch touchscreen.


The 2015 Altima also has more available safety technology like lane departure warning, blind spot monitoring and rear cross traffic detection. The 2015 Sentra doesn't give you any of these safety features.

Which is Right for You?

The 2015 Nissan Altima and the 2015 Nissan Sentra are two great vehicle options. They differ slightly in size, engine performance, interior features and, of course, price. The 2015 Nissan Altima averages to be about $6,000 more expensive than the Sentra. The Altima gives you a bigger size and better engine performance as well as more technology options. The Sentra still gives you good space and great fuel efficiency and it is cheaper than the Altima.


Which vehicle you choose depends on your priorities. If you are looking for a well-priced compact car, the Nissan Sentra is for you. If you are looking for a bigger car with all the features, you should look into the Nissan Altima.
