GMC is using an unusual method to make its latest SUV more fuel efficient: using adhesive. The car manufacturer makes use of aircraft-grade adhesives for the 2017 GMC Acadia. What this has done is reduce the use of rivets and welds and helped in the creation of a body so stiff, it made it possible to use thinner steel. The SUV drops over 700 pounds from its predecessor of while giving 23 miles per gallon with this change. The 2016 model only got 18 miles per gallon.
The change is essential because the US government wants its automakers to reach an average fleet goal of 54.5MPG by the year 2025. This means fuel economy has to happen across many models as possible—even gas-guzzling SUVs.
