Japanese Technology Eliminates The Need For Film With Windows That Switch Between Transparent And Opaque In Toyota’s Luxury SUV
Have you ever thought about not having to apply film anymore? This technology has the potential to become a ‘digital film’. Toyota caught attention by incorporating a sleek and discreet technology in its luxury SUV, the Century.
The model, available only in Japan, features rear side windows that use electrochromic glass — a feature that allows the level of transparency of the material to change at the touch of a button.
Silent But Powerful Technology
Although electrochromic glass is not new to the automotive industry, its application in the rear windows of the Century represents a unique use.
-
A French brand placed a car on four huge red balloons to prove that its suspension made the vehicle “float,” and the surreal scene became one of the most iconic and unusual images in automotive history.

Jeep Avenger begins production in Brazil, debuting as the brand’s new entry-level SUV and inaugurating an unprecedented phase by becoming the first national Jeep manufactured outside of Goiana, as part of a R$ 3 billion plan.
-
Costing R$ 12,490, the new Shineray Urban Lite 150 “cheap one” arrives in Brazil with a CVT transmission, digital dashboard, and LED lights, making it more affordable than the Biz and targeting those who want to abandon the bus.

Ducati brings to Brazil the Superleggera V4 Centenario: 228 hp that become 247 with a track kit, carbon fiber and carbon-ceramic brakes, estimated price between R$ 1.5 and 2 million, deliveries only in 2027.
Until now, this type of glass was more common in sunroofs to protect occupants from excess sunlight.
In the Century, the focus is on the comfort and privacy of passengers.
Instead of simply darkening, the rear windows become frosted, allowing soft light to enter while completely blocking outside visibility.
Toyota reports that the windows can switch between three modes: transparent, translucent, and opaque. In all cases, light continues to pass through, but with no visibility from the other side. The effect is compared to being “in a Japanese-style room,” creating a reserved and elegant atmosphere.
Development And Innovation
The technology was developed by the Japanese company AGC.
According to the manufacturer, the Century is the first car to feature electrochromic glass in its doors.
This required additional testing, as the doors are moving parts and subject to more mechanical stress than fixed areas of the roof, where the system was typically used.
The operation is based on a special film with particles arranged in a random manner.
When a voltage is applied, these particles align and make the glass transparent. Without energy, the material returns to its original state, scattering light and generating the frosted effect.
Silent Luxury In The Japanese Market
Although the Century was introduced two years ago, the highlight for the windows has emerged only now, after other vehicle innovations gained focus.
The SUV features rear seats that recline almost completely, with electric foot support, and even a special driving mode for rear occupants. The message is clear: those traveling in this car are usually not driving.
While consumers outside Japan still do not have access to the model, the success of the Crown in international markets keeps the expectation alive that the Century, along with its sophisticated windows, will also gain the world.
