2018 Toyota Highlander vs 2018 GMC Terrain

When it comes to choosing a family SUV, things can get a bit tough. There are so many options out there and it makes wading through the potential vehicles very difficult. Thankfully, there are a few vehicles that stand above the crowd. One of these vehicles is the 2018 Toyota Highlander. To prove it, we’ve done a bit of research on the Highlander and one of its greatest competitors; the 2018 GMC Terrain. Now, we’ve taken what was found and organized it into a side-by-side comparison to see just what SUV comes out on top.

In an effort to make this as fair as possible, we’ve taken the specs and features of the lowest trim of each vehicle. This means that you’ll be looking at the specs and features of the 2018 Toyota Highlander LE with the 2.7L 4cyl engine. It is compared to the 2018 GMC Terrain SL with the 1.5L 4cyl Turbo engine.

Now, let’s take a look at what these 2 SUV vehicles have to offer their potential drivers.

Advantages of the 2018 Toyota Highlander

As you can see in the table above, the 2018 Toyota Highlander offers just a bit more when it comes to the horsepower. While the 2018 GMC is not a slouch by any means, the Highlander still has 15 hp more than the Terrain does.

The Terrain makes up for it with better gas mileage, getting an EPA-estimated 26 miles per gallon in the city and 30 on the highway, compared to the 20 mpg in the city and 24 on the highway for the Highlander.

However, the Highlander evens things out again by having a much larger fuel tank. This means that, while you might have better gas mileage in the GMC Terrain, you’ll still potentially find yourself going farther in the Toyota Highlander before you need to stop for fuel, depending on your own driving style and the driving conditions.

If you have a larger family, or frequently find yourself needing to cart around more than 5 people, then the Highlander is definitely a vehicle you’ll want to choose over the Terrain. The GMC Terrain seats up to 5 people, while the Toyota Highlander can seat up to 8.
