The new software update for Model Y includes a launch mode that is called “Cheetah stance”, which lowers the front axle and adjusts damping to improve traction.
Tesla described the new suspension: “We’ve also upgraded our air suspension system for Model S and Model X with fully adaptive damping, giving it an ultra-cushioned feel when cruising on the highway or using Autopilot, and a responsive, exhilarating confidence during dynamic driving.”
“The most surprising thing is that the new launch mode doesn’t just improve traction with the new stance, but it also unlocks more power in the Model S Performance Raven.
Over the last few years, Tesla started only allowing owners to get the full power output out of their performance cars through launch mode, which they claim was to “protect the powertrain.”
DragTimes now finds that with the new launch mode, he is seeing a peak power increase from 580kW to 614kW, which is the equivalent of about 45 more horsepower.
As for the times, the results are going down from 2.47 to 2.41 seconds for the 0 to 60 mph acceleration, 6.77 seconds at 102.23 mph to 6.71 seconds at 103.55 mph for 1/8 of a mile, and 10.67 seconds at 124.70 mph to 10.54 seconds at 127.5 mph for the quarter-mile.” (via Electrek).
