Don't buy used

Word on the street is that Ford has (again) lowered pricing on its Mustang Mach E electric car. The base real-wheel drive version can now be had for (just) under $40,000. Ford is also throwing in $7,500 on leases. Combining with the federal EV tax credit of another $7,500 makes the base Mach E a highly attractive option if you just need a simple electric runabout. I would consider one if I actually needed a car.

And because I wouldn’t want to buy a used electric vehicle. You simply cannot trust it. The thing no one seems to be talking about is battery degradation. Much like the battery in our smartphones, the cells in electric cars degrade with use and time. But how much it degrades does not scale linearly with mileage. Depending on the usage pattern - how often it’s charged, how fast, to what level, etc - an EV with 50,000 miles can potentially have a healthier battery than a 20,000 miler.

This is a critical piece of information in electric vehicles because the battery is everything. A degraded battery cannot motivate the car to the same number of miles as new on once charge. At least with a combustion car you can expect the same range in a high-mileage gas engine.

The problem is we have no way of knowing about battery degradation. The electric cars (currently) don’t show the health percentage (our smartphones do). Venturing into the vast menu of a Tesla Model 3 doesn’t reveal this information. I think manufacturers should include battery health indicators, plus showing how much maximum range has been lost as well. As I said, range in an electric car is everything.
