The GMC Acadia Denali has more interior space than the XC90. The Acadia also takes up less space in the garage than the Volvo. I reviewed the 2017 GMC Acadia Denali for a week and found something interesting: it's actually better than the Volvo XC90. Granted, the GMC isn't perfect, but it's 310hp V6 engine and smooth ride quality make it enjoyable to review.
