Hyundai has launched a new window tint, called Nano Cooling Film, which is said to offer a “significant improvement in interior cooling performance” when compared to conventional tint films, which in turn can potentially reduce the use of air conditioning.

The film significantly reduces the interior temperature in a vehicle, making occupants more comfortable and reducing energy consumption. The film is transparent and Hyundai said it won’t violate local regulations, as can happen with too-dark tint.

The film is expected to work best in hot, dry climates. The automaker is testing it on some 70 vehicles in Lahore, Pakistan, where temperatures can exceed 50°C (122°F) in the summer. Hyundai said the film’s cooling effect is optimized at hotter ambient temperatures.

The transparent film consists of three layers. The outer layer radiates heat at mid-infrared wavelengths from the vehicle’s interior to the outside, while the two inner layers “reflect incoming heat at near-infrared wavelengths,” the automaker said, which reduces the heat entering the vehicle. In addition to blocking the driver’s vision at night, dark tint can “release absorbed heat into the vehicle,” Hyundai said.

In testing, the Nano Cooling Film reduced the interior temperature near the driver’s head by up to 10.98°C when compared to conventional tint film. Compared to a vehicle without any window tint, the film reduced the temperature by up to 12.33°C.

When comparing the temperature of the dash pad, the film reduced the temperature by 15.38°C compared to regular tint, and up to 22°C for no window tinting. And note that those are the temperature reductions, not how warm it was in the car.

The film has been applied to customers’ cars at no charge to them, and Hyundai will use data from the pilot project to gauge its quality before putting the film into mass production. The automaker first showed the window film at a media event in July 2023, with plans to test it in real-world conditions as part of its development of advanced material technologies.

Education

Jil McIntosh graduated from East York Collegiate in Toronto, and then continued her education at the School of Hard Knocks. Her early jobs including driving a taxi in Toronto; and warranty administration in a new-vehicle dealership, where she also held information classes for customers, explaining the inner mechanical workings of vehicles and their features.

Experience

Jil McIntosh is a freelance writer who has been writing for Driving.ca since 2016, but she’s been a professional writer starting when most cars still had carburetors. At the age of eleven, she had a story published in the defunct Toronto Telegram newspaper, for which she was paid $25; given the short length of the story and the dollar’s buying power at the time, that might have been the relatively best-paid piece she’s ever written.

An old-car enthusiast who owns a 1947 Cadillac and 1949 Studebaker truck, she began her writing career crafting stories for antique-car and hot-rod car club magazines. When the Ontario-based newspaper Old Autos started up in 1987, dedicated to the antique-car hobby, she became a columnist starting with its second issue; the newspaper is still around and she still writes for it. Not long after the Toronto Star launched its Wheels section in 1986 – the first Canadian newspaper to include an auto section – she became one of its regular writers. She started out writing feature stories, and then added “new-vehicle reviewer” to her resume in 1999. She stayed with Wheels, in print and later digital as well, until the publication made a cost-cutting decision to shed its freelance writers. She joined Driving.ca the very next day.

In addition to Driving.ca, she writes for industry-focused publications, including Automotive News Canada and Autosphere. Over the years, her automotive work also appeared in such publications as Cars & Parts, Street Rodder, Canadian Hot Rods, AutoTrader, Sharp, Taxi News, Maclean’s, The Chicago Tribune, Forbes Wheels, Canadian Driver, Sympatico Autos, and Reader’s Digest. Her non-automotive work, covering such topics as travel, food and drink, rural living, fountain pen collecting, and celebrity interviews, has appeared in publications including Harrowsmith, Where New Orleans, Pen World, The Book for Men, Rural Delivery, and Gambit.
