We now offer dual motor support for the P85/90/100D powertrains. In the winter of 2018 we installed a dual motor powertrain in our 818 test car. We ran a 9.5 second quarter mile in the spring of 2018 and then this summer we went back to the track and ran a 9.3 second quarter mile at 138 mph. The dual motor firmware for the controller implements traction control, and is available now.
