A side-by-side comparison of the 2018 GMC Terrain vs. 2018 Subaru Outback

2018 GMC Terrain vs. 2018 Subaru Outback

GMC vehicles are lauded for their overall performance, high-quality interiors made from premium materials and a wide array of the latest technology. The new GMC Terrain, currently available at the Billion Auto Group showroom, is one of the most impressive examples of what the automaker has to offer. However, this long-standing success has certainly drawn attention from the automaker's rivals. In order to help car buyers get a stronger understanding of what is available to them, let's take a look at the 2018 GMC Terrain vs. 2018 Subaru Outback. To be sure, the Outback has a lot going for it – but will it be enough to overtake the radical changes made to the Terrain this year, which include a complete redesign and new engines? Our initial thought is, no.

Among the areas where the 2018 GMC Terrain is able to outshine its Subaru competitor is in overall drivability and convenience. The comfortable interior of the 2018 Terrain is perfect for growing families with diverse interests which also require plenty of space. Lots of today's SUVs come with an infotainment system which is compatible with smartphone applications for Android- and Apple-based devices. In fact, both the 2018 Terrain and 2018 Outback have such interfaces. However, Terrain owners will be able to have even more connectivity thanks to GMC's innovative 4G LTE Wi-Fi hotspot. Several phones, tablets and laptops can be connected to the high-speed internet connection while on the road.

Performance specs: 2018 Terrain vs. 2018 Outback

It's not uncommon for automakers to retain powertrain equipment in a vehicle when it's redesigned. If GMC is anything, it's uncommon. In addition to a more refined interior and a more aerodynamic exterior, the 2018 GMC Terrain is also available with three brand new engine options. Base models are outfitted with a turbocharged, 1.5-liter, four-cylinder engine making 170 horsepower and 203 pound-feet of torque. By comparison, the 2018 Subaru Outback starts out with a naturally aspirated four-cylinder engine of its own, that makes about five more horsepower. This advantage is quickly mitigated by the additional towing capacity the Terrain has over the Outback.

The big performance news for the 2018 GMC Terrain is the introduction of a turbocharged diesel engine. Buyers choosing the diesel option will be able to use 240 pound-feet of torque as well as being able to record as much as 40 miles per gallon on the highway, according to Environmental Protection Agency fuel economy estimates.
