5 reasons to buy the 2020 GMC Acadia

1. Off-Road ready

If you enjoy going on occasional off-road trips, you can't go wrong with the 2020 GMC Acadia. It comes with available all-wheel drive on all but the base trim, which is great if you find yourself often driving over difficult terrain or in varied weather conditions. The all-wheel drivetrain provides better traction and makes the throttle much more responsive, ultimately helping you maintain control over tricky surfaces.

2. A nice selection of trim configurations

Another reason you might be attracted to the 2020 GMC Acadia is the versatile trim lineup that includes something for everyone. Starting at the base SL trim you'll enjoy a 2.5L four-cylinder engine and seating for you and six friends. Move up to the newly added AT4 trim that's specially designed for off-road driving and enjoy some extra adventure on the weekends. Finally, all the way at the top-level Denali trim you can expect lots of advanced tech features and upscale interior touches, ideal for those looking for a little luxury. With that many options, you can easily choose a trim that will fit your lifestyle.

3. Abundant storage space

Plentiful storage is often a big factor when it comes to buying an SUV. If you carry a lot of cargo, the 2020 GMC Acadia delivers in this area. With an interior cargo volume of 41.7 cubic feet, it offers plenty of space for your groceries, sporting equipment, a few suitcases, or any other robust and heavy items you might need to haul. The total cargo volume increases to 79.0 cubic feet when you fold down the rear seats, which means your DIY projects or trips to the garden center will be easy too.

4. Bold exterior

Although performance, convenience, and functionality are probably at the top of your list when searching for an SUV, a nice looking exterior is always a welcomed bonus. The Acadia boasts a bold and stylish design that helps it stand out from the crowd—and in your driveway. The newly-designed front end for the 2020 model year includes LED headlights with GMC's signature C-shape and an imposing grille that will leave a lasting impression as you drive on by.

5. Lots of technology

The 2020 GMC Acadia is equipped with lots of tech features that help provide a pleasurable riding experience. For starters, it comes with an intuitive and handy infotainment system featuring an eight-inch touchscreen as well as Apple CarPlay and Android Auto compatibility that keeps the driver and passengers connected and entertained. It doesn't hurt that it includes five USB ports and automatic temperature control as standard features, either.
