Recently, Tesla's world has revolved around the Model 3. But there's more coming soon from the company. Rumors of an upgraded and pricier Model S began circulating last month, and now more details about that EV have emerged. According to CNET's Tim Stevens, the overhauled Model S could debut as early as next week, based on information from sources inside Tesla. The report claims Tesla is set to make "luxury-minded" changes to its flagship vehicle, internally and externally, as Elon Musk's team looks to compete against Audi, BMW and Mercedes-Benz.
