55-75 is a perfect example of the superiority of EV over ICE.
In a gasser, cruising at 55 will usually have the car lugging around in top gear, turning relatively few revs to optimize fuel economy. Pressing on the accelerator usually just results in a bog or a downshift.
When suddenly called upon to make a pass the pedal is pressed to the floor, the electronice determine that the driver wants to accelerate and will call for multiple downshifts like from 8th gear down to 3rd. The transmission will make those shifts and the engine will be accelerated to higher revs to effect the torque multiplication necessary to move the heavy car as fast as possible.
The higher revs will cause the turbos to also engage and speed up to maximize torque. (for naturally aspirated gassers, this step will be eliminated). The boost will build and the revs will rise until maximum safe revs are attained.
The car will then pause, shift up to the next gear, and torque will then be re-engaged to provide addition thrust as it again moves up into the more powerful area of the revs.
This adds tremendous shock and strain to the drive train. The tires may break loose on the shifts if the road is wet or slick.
After the pass is finished, things will once again quiet down as the transmission once again shifts into top gear to reduce engine wear and increase fuel consumption. All this output varies considerably depending on elevation and air density.
At full throttle and full revs, maximimum wear and damage is done to an ICE. The temperatures are at maximum and all drive line components are at maximum stress.
For an EV it is exquisite simplicity. The electric motors already have the driveline torque loaded and flooring the pedal simply adds the maximum torque available to the drive wheels. No shock, jolt, shifting or massive differentials of torque load. The car simply accelerates forward at the maximum torque that the batteries and motors can provide.
Little overt drama, but the driver has constant control of throttle, and the computer adjusts for any traction issues in a smooth and efficient manner. In an ICE the driver is committed to full throttle. Lifting just a little will cause a upshift and maximum acceleration will be lost. Hard to modulate between 80% thrust and 100% thrust.
For most drivers, the EV will give a far safer and better controlled passing event than the jerky gasser. The driver maintains precise torque application with his foot and can stay at max or cut to anything else at any point in the pass.
As speeds go up, the benefits will switch over to the multi speed transmission of an ICE. Believe this is one of the reasons that Taycan has been engineered with two gears. This will allow better performance on the unlimited speed of the Autobahn and Autostrata.
But to answer the OP, in most cases, the 55-75 passing events will still be more easily accomplished in the EV.
A side benefit is that the pass can be made without triggering anxiety to all the passengers, annoying the Wife and waking the baby
. Passengers will most likely not even look up from their cell phone screens.
Model 3 performance will accomplish this maneouver better than most other similarly priced 4 door sedans.
