number of ribbons

The material addressing the Tesla battery pack evolution did not specify which mode became the target for cooling improvement.
They had mentioned the inability to 'hot-lap' the 1st-gen Model S, at Laguna Seca, regardless of what they did to the car, including 17-bags of ice under the pack before the 'Track' driving. The car would automatically cut power to 50% in order to protect itself; which was on track to at least match the performance of the Dodge Charger Hellcat ( a 4.4-mpg car under 'race' conditions ).
For the 2nd-gen Model S, Tesla engineer's second ribbon doubled the heat conduction interface contact area. They also rewrote the software, allowing the 'hotter' motor to use the 'cooler' battery pack as a heat sink. Good for 4-laps.
The Model 3 can be 'raced' as long as there's battery capacity. It recently set a class speed record on the Pikes Peak hill climb.
