on Wednesday, Tesla surprised everyone by unveiling the long-rumored refresh for its Model S sedan. ( The Model X SUV received major updates as well.) On the outside, the Model S has features a new front bumper with slightly different air intakes, a tweaked rear diffuser and new 19- and 21-inch wheel designs. All of the exterior trim is now finished in black to match the Model Y, but the paint color palette remains the same, with white being the only no-cost option. The overhauled interior is the star of the show, though. It's been completely redesigned, marking the Model S' first major update since its debut way back in 2012. There's a large 17-inch central screen much like that of the Model 3 and Model Y, but the orientation has changed -- it's horizontal instead of portrait. The S retains a 12.3-inch digital gauge cluster in front of the driver, as well. Tesla says the new center screen is basically a gaming computer with 10 teraflops of processing power, and the released images show it running the popular fantasy RPG game Witcher 3. Enlarge Image
