Over the weekend, I used my R1T to tow a car hauler with my Land Rover 110 on it from Austin to San Antonio. I used about 53% of the battery pack on the way there and about 38% of the battery on the way back with an empty trailer. Overall, it towed like a dream.
Since this was my first time towing with the truck I charged the battery to 100% overnight. As you probably know, battery regen turns off when they battery is in a high state of charge which made for an interesting start. The first part of my trip was hilly and I used a lot of battery dragging the trailer up these hills and got zero regen back down. From memory, I think I averaged .73 miles/KWH for the first 15 minutes. It was enough where I was doing the math to see if I needed to stop mid-trip to charge. Thankfully, the trip leveled out and the regen turned back on as the state of charge came down.
The other thing to note is that I hit a fair bit of traffic both ways on this trip. Saturday on I-35 between Austin and San Antonio isn't a fun drive.
Trip there
Distance: 82.8 Miles
Average speed: 43 MPH
Efficiency: 1.18 mi/KWH
Total Energy: 70 kWh
Total weight: ~6700 pounds - (Trailer weight: 2200 pounds, Land Rover weight: ~4500 pounds)
Fast Charge in San Antonio
Energy added (according to EA): 66 kWh
Time: 37 minutes
Max charging speed: 157.6 kW
Cost: $9.63
State of charge: 39% to 86%
Note: I didn't need to charge to 86%. We stopped for lunch and wrapped up our charging session when we finished. The session went great but it was a little annoying that I had to block part of the parking lot with the trailer. Thankfully, the last charger on the end was available so I was only blocking empty parking spaces. I probably would have had to disconnect the trailer if I had to use a charger in the middle.
Return trip
Distance: 84.6 Miles
Average speed: 45 MPH
Efficiency: 1.73 mi/KWH
Total Energy: 49 kWh
Total weight: 2200 pounds - (Trailer weight: 2200 pounds)
