Ford says that sales of its Vista Roof have increased since it was introduced on the Edge in 2007. Sales are up four percent over 2010 and up 16 percent overall on the Edge. The Vista Roof was added to the option lists of the Mustang, Flex, and all-new 2011 Explorer.

According to Ford 32 percent of Flex CUVs, 48 percent of new Explorers, and 56 percent of Edges are sold with the Vista Roof. Sheryl Connelly, manager of Ford's Global Trends and Futuring, credits the high take-rate to customers who have been requesting more light in their vehicles over the last five years.

"We are seeing more buildings utilizing glass structures because letting natural light in is a popular architectural trend," Connelly said in a press release. "This trend has crossed over to the automotive industry, and Ford's Vista Roofs open the car to more sunlight which keeps drivers energized and gives the luxurious feel customers desire."

Ford says its "panoramic glass roofs filter the sun's heat-generating infrared (IR) rays and burn-causing ultraviolet (UV) rays" -- comparing its protection to sun screen with an SPF rating of 50. Ford also claims the Vista Roof increases exposure to sunshine allowing the body to release Vitamin D and regulate the body's synthesis of melatonin.

"It is important to be cautious when exposing yourself to the sun because IR and UV rays are dangerous for your skin," said Dr. Douglas J. Arends, a Psychiatrist from Royal Oak, Michigan, in Ford's press release. "But exposing yourself to the light is good because it releases Vitamin D which actively improves your mood."

"The Vista Roof is great because it's like getting a convertible with added benefits," said Amy Marentic, Ford Group Marketing Manager, in the release. "It is a unique feature that offers consumers open-air-like driving without the need for sunscreen."
