Model S P90DL
DragTimes recently tested its Tesla Model S P90DL (Ludicrous) with the latest Launch Mode update.
Launch Mode is a special feature, which puts motor torque against brakes for a while (up to 4 seconds), so that after releasing the brakes, the car accelerates from a slightly different operating point for the motor.
Most people wondered whether Launch Mode would bring some benefits to acceleration times and it seems the answer is yes.
The car is quicker, although the difference is thin. In 0-60 mph (90.5 km/h) you will not feel the difference:
"Software Version 7.0 release 2.7.77 (without Launch Mode)
0-60 MPH: 2.86 seconds 0-100 MPH: 7.56 seconds 1/4 Mile: 11.32 @ 118.3 MPH
Software Version 7.0 release 2.9.40 (with Launch Mode)
0-60 MPH: 2.82 seconds 0-100 MPH: 7.46 seconds
1/4 Mile: 11.26 @ 118.7 MPH"
Moreover, DragTimes notes that some runs were similar and points out that the car itself is equipped with lighter wheels:
"We also did some back to back 0-60 MPH testing with and without launch mode and while the best 0-60 MPH time obtained was using Launch Mode some of the runs were dead even between using Launch Mode and not using it. Wheels on the car are lighter than stock by Pulse a division of Speed Design GmbH."
