The sixty-sixth day had begun in sunny Phoenix, AZ. We made a pit stop at Discount Tire in Phoenix. They serviced our EV specific tires and let us know that we were all good to go. Interestingly, specific tire compounds are also necessary to support the unique driving experience of an EV. Compounds that contain raw materials such as high-loading resin and silica extracted natural resources are key components to developing EV-specific tire products. With inherent durability improvements, the stronger and more durable compound better assists the power delivery and driving characteristics of an EV over conventional compounds. It was a necessary stop for us and we would like to thank them for the quick and efficient service. The Phoenix heat made us quite thirsty so we made a stop at a local juice bar that displayed a T2 bus with a large smiling face over the top. We then stopped at an Electrify America station and got to see first hand what the people at ABB have to do in order to service these stations. There was also a Tesla taking advantage of the CCS combo adapter made specifically for Tesla vehicles. Water is also a very scarce resource in the desert. We got to see what how it was actually displayed in a nice local neighborhood, and it served as almost a status symbol for the area. Next we visited VW’s Arizona Proving Grounds, where they test things like charging vehicles in extreme conditions. We would like to thank the lovely employees for coming out to take a photo. Later when the hot sun receded we made our way down to Tucson, AZ. We got a nice shot of the ID.4 in front of a large Mormon Church and concluded the day in Tucson.
