Of the winter tires available, I think the Nokian R3s are your better choice. With the REx, the only winter tires that I've found are a square set, so you'd at least need to buy new rear wheels, if not a full set. I think Canadian i3s now come with TPMS, but if so, make sure the wheel you choose all...

As a percentage of people that have had a catastrophic battery cooling problem, it's miniscule, so putting that into the equation for average running costs is kind of flaky. That is not a wear item. If you take into account normal wear items (brakes, maintenance, oil change, filters, checks), the co...

Most of the batteries in use utilize somewhere in the high 300-400 volts fully charged. There are some out now, and probably more coming, that utilize up to 800-volts. So, while I haven't looked, I'm guessing the DC fast charging 'levels' may be tied to the voltages available. A CCS unit is a variab...

As I said earlier...BMW did think about the locking...it made the assumption that if it was unlocked, but you didn't open a door, it was a 'mistake', and after a delay, will relock them. There's no easy assessment of whether you wanted the windows down or not as instead of a single, short press, to ...

When DCFC is attempted, the ACV input plug pins get repurposed to be serial data lines that communicate with the CCS unit and are required to manage the charging of the vehicle. As was mentioned, the weight of the plug and (mostly) cable can distort the socket so that the serial data communications ...

Batteries degrade from temperature excursions beyond design and (mostly) the number of charging cycles. Given the same miles driven, a vehicle with a smaller battery will require more charging cycles. Note, one cycle is from 0-100%, not the number of times it is plugged in, so one from 0-100% is abo...

Most of what you can change on a BMW with something like Bimmercode is changing constants, you are not actually changing the operational code. YOu can think of the simple equation for the circumference of a circle...the formula is fixed. You change the Diameter value to account for different sized c...

As more and more EVs hit the roads, paying for the highway infrastructure based on fuel taxes will become way lopsided. Expect everyone to eventually end up paying a per distance tax and the fuel taxes at the pump may go away. The administration of that could be messy, but I think it will happen, ma...

The REx normally doesn't run, so there's a special diagnostic mode you have to put the vehicle in to run the REx so they can do tailpipe emissions checks. It's not hard, but it's not readily apparent unless you are familiar with the BMW i3's service instructions. I don't think it's in the user's man...

The first couple of years, they supplied 12A EVSEs in the US, then they dropped it to 10A units. The US electrical code says a device like an EVSE must derate the supply to NGT 80%, so the 12A would be okay on the nominal 15A circuits in the US. The hassle is, there could be lights, a garage door op...
