Electric carmaker Tesla’s Model S is a four-wheeled technology showcase. Not only is the Model S a performance-focused electric car — with the ability to rocket from 0 to 60 in 5.6 seconds — it packs one of the slickest interiors in the biz. The Model S eschews traditional physical instrument clusters in favor of a completely digital layout. That starts with a massive 17-inch touchscreen display, which provides all manner of info, including navigation, media and climate controls. Want to surf the Web? The Model S is Wi-Fi-ready, so you can get online from the in-dash display as long as the car is in park.
