Assumptions:
1. the Leaf has 100 mile highway range and the Model S has a 160 mile highway range at the same speed ( 55mph )
2. Both cars start full.
3. Chademo charges at 50kW and stops at 80% ( thus a Chademo charge gives the Leaf 80 miles of range )
4. The Model S charges at 20kW and charge starts tapering at 85% linearly down to 100% ( so you stop charging shortly after current tapering starts unless charging a little more helps you avoid a stop )
5. There is a 15 minute overhead to pull off the highway, into the charge area, start charging, walk back to your car when charging is done, disconnect and get back on the highway
6. Charging stations are placed so you can stop at the optimal spot for each car along the highway but you keep 10 miles of safety when you stop to charge.
( So the Leaf stops at 10% and continues at 80% using 70 miles between charging stops )
Clearly any race less than 90 miles is a tie.
Any race between 90 and 150 miles the Tesla wins handily.
To drive 230 miles the Leaf will take 250 minutes of driving time and 72 minutes of charging time.
To drive 230 miles the Tesla will take 250 minutes of driving time and 75 minutes of charging time.
To drive 270 miles the Leaf will take 295 minutes of driving time and 99 minutes of charging time.
To drive 270 miles the Tesla will take 295 minutes of driving time and 105 minutes of charging time.
However the Tesla can charge at a J1772 at its destination ( if one existed there ) and be ready to return home after a 2 hour stop if it arrives empty, the Leaf would take up to 8 hours on J1772 so to do a quick turnaround would require an extra 30ish minute QC stop.
To drive 400 miles the Leaf will take 436 minutes of driving time and 168 minutes of time stopped to charge. Total time 604 minutes. 10 hours and 4 minutes.
To drive 400 miles the Model S will take 436 minutes of driving time and 218 minutes of time stopped to charge. Total time: 10 hours 54 minutes
Over a very long distance the Leaf advantage grows.
If the charge stops are not optimal and you have to average 25 miles of range remaining when you stop:
To drive 230 miles the Leaf will take 250 minutes of driving time and 87 minutes of charging time.

To drive 270 miles the Leaf will take 295 minutes of driving time and 114 minutes of charging time.
To drive 270 miles the Tesla will take 295 minutes of driving time and 110 minutes of charging time.
To drive 400 miles the Leaf will take 436 minutes of driving time and 183 minutes of charging time.
