If you are shopping for a new mid-size SUV then be sure to look at the new GMC Acadia. The Acadia is a versatile vehicle with ample room for passengers and cargo alike. It is perfect for families, long road trips, or taking the boat to the lake for some weekend fun. The exterior is handsomely styled and will turn heads as you motor about the greater Aurora, and Denver areas. Inside you will find a spacious cabin with three rows of seating. The second and third rows can fold flat to accommodate extra luggage or bulkier cargo. The interior design is pleasant to the eye and features intuitive controls and tasteful accents throughout the cabin. A large infotainment center is featured prominently in the center console. With an intuitive menu system and a snappy touchscreen, you will find the system easy to use. The Acadia comes standard with all connectivity and features you will need, and Android Auto and Apple CarPlay enable you to effortlessly stream your music or take hands-free calls on the go.
When it comes to customizing your Acadia there are a multitude of options available. There are five trim levels, and multiple option packages such as the Elevation Edition, or Pro Safety Plus package that can be added onto certain trims to further customize your vehicle. Some of the available options include, but are not limited to, second-row captain chairs, heated seats, 20-inch wheels, head-up display, and 360-degree camera system. Depending on the trim you choose you will have one of three engine choices. The base engine is a turbocharged 2.0L engine that outputs 230HP and a 3.6L V6 that outputs 310 HP available. These are paired with a nine-speed automatic transmission. Front wheel drive is standard and all-wheel drive is an available option. Depending on which engine/trim you choose, the Acadia is rated to tow from 1,000 lbs. with the base engine. This amount goes up to 4,000 lbs. with the more powerful V6 engine. A robust package of safety features will keep you and your passengers safe as you motor around the greater CO area.
