Tesla's more affordable Model S 60 is back, and it comes with a more attractive base price of $66,000 (£53,000). That's around $4,000 less for the 60kWh sedan that the automaker originally sold from 2012 to 2015 before it was replaced by the 70D. To sweeten the deal, Tesla added a 75kWh battery pack to the car and the extra power and range can be unlocked via a software update if the owner needs to do so. Of course, there's an added cost involved for the update, but exact pricing for that hasn't been revealed.
