Christmas trees create more drag for SUVs

Engineers at the University of Vermont have proven that strapping Christmas trees to the top of sport utility vehicles burns extra gas. UVM associate professor of engineering Darren Hitt and a PhD student discovered that SUVs topped with trees have 26 percent more aerodynamic drag than tree-less SUVs.

They say that results SUVs using an extra 53,000 gallons of gas a year – about $100,000 in extra fuel costs nationwide. They based their research on a 2004 Ford Explorer, a seven-and-a-half-foot tree wrapped in plastic netting, and a ten-mile round trip to a tree lot.
