Originally known for its budget performance and rather drab appearance, the old Kia Niro wasn’t the most exciting of cars. With the release of the all-new Niro, however, it’s clear that the Korean manufacturer has got the message. They’ve given the family SUV a more attractive look inside and out, without sacrificing the low running costs that made its predecessor an enticing option for those keeping an eye on their wallet.

But with all the different trim options available, the question on the lips of many a motorist is “how do the new variations differ exactly?” To help make that decision easier and clear up any confusion, we’ll break down the differences between the Kia Niro 2 and the Kia Niro 3 for you below.

How big is the Kia Niro?

Before we get to comparing the 2 and the 3, let’s take a look at one of the most noticeable things about the new models: their size. Compared to the old Niro, the new versions are taller, wider and longer at 1,585mm, 1,825mm, and 4,420mm respectively.

And considering the previous version was no slouch when it came to space, the larger size of the new Niro makes for plenty of legroom, headroom and space for passengers in the back. Likewise, the plethora of storage bins, the low window lines, and the high ceiling add to the overall spaciousness too.​

How reliable is the Kia Niro?

The second-gen Niro hasn’t been around long enough for any data on its reliability to have come to light. With that said, the previous generation, as well as Kia itself, tends to score highly on customer satisfaction surveys.

Likewise, the new Niro’s bevy of safety technology, including Highway Driver Assist, Forward Collision Avoidance, Lane Keep Assist, Emergency Stop Signalling and a Blind Spot Detection system with Rear-Cross Traffic alert, suggests that it’s likely to perform well in terms of safety and reliability.

Having said that, these safety features are only found in the Niro 3 – time will tell how the reliability differs from trim to trim in this regard.

What is the difference between Kia Niro 2 and 3?

The first thing to keep in mind when it comes to the new Niro range is that, whether you go for 2 or 3, both are available in electric, hybrid and plug-in hybrid electric vehicle (PHEV) models.

The 2 and the 3 refer to the vehicle’s trim, i.e., the differences in terms of features and equipment that help buyers differentiate between different cars in the same family. It’s these differences that we’ll be taking a closer look at over the course of this article.

So, let’s get started…

Wheel size 

All Niro 2 models come equipped with 16” alloy wheels, whereas 3 models feature 18” alloys.

Audio, communication and information

Both the Niro 2 and 3 feature a 4.2" Supervision Colour Cluster Display, while the Niro 2 features an 8-inch Touchscreen Display in its infotainment system, although you’ll need a third-party navigation system if you want to get from A to B. The 3, on the other hand, upgrades this to a 10.25-inch Touchscreen Display, complete with built-in navigation.

Tend to make a mess of parking? It’s probably best to go for the Niro 3: it’s equipped with Front Parking Sensors, so you can take care of any blind spots and obstacles with ease.​


When it comes to the inside of the new generation models, the upholstery differs between the two trims. The Niro 2 is finished with cloth upholstery, whereas the Niro 3 comes equipped with cloth and vegan leather upholstery.


The 2 and the 3 are fairly similar when it comes to storage, with both featuring overhead console and second-row storage, along with front and rear door storage, and a luggage compartment. Where they differ, however, is in the 3’s front seatback pockets to the driver and passenger seats; these are both lacking in the 2 Niro.


Good news for drivers with dodgy backs: the Niro 3 has seats with Aircell lumbar support which help to take the pressure off the spine, and delivers some much-needed relief from lumbar and coccyx pain. Both the passenger and driver seats are heated in the 3 too, as is the steering wheel, which makes for some toasty winter-time drives. Unfortunately, both the heat and support features are not available in the 2.


Both the Niro 2 and Niro 3 come with a 7-year or 100,000-mile warranty – whichever of these comes first.
