Tesla states that they improved 3x the thermal endurance of the Model S and Model X Performance vehicles due to the new software update. Tesla updated the Model S Performance 0-60 mph acceleration to 2.3 seconds on its website.
After Launch Mode, Tesla enables the full power of its performance vehicles, including Cheetah stance and using the new adaptative air suspension, which improves traction. According to an e-mail: “You asked for it. With our latest over-the-air software update to Model S Performance, we improved 0-60 acceleration to 2.3 seconds and quarter-mile time to 10.4 seconds. Go for more back-to-back runs with improved thermal endurance, and activate Launch Mode with a press of the pedals. Launch Mode’s new Cheetah Stance lowers the front axle and adjusts damping before entry for better traction and faster acceleration off the line. You’ll automatically receive this update based on your location and vehicle configuration—you can’t request the update. Connect to Wi-Fi or a mobile hotspot to download and install quicker.”
There are no specific details about the improvements, but now the Model S Performance is officially going from 0-60 mph in the time of the Dodge Challenger SRT Demon.
