Recently I bought a second EV, a BMW i3-REx, so I could work on my Tesla Model 3 when something might take more than a day:
- 2017 BMW i3-REx
- $15,000 (add taxes and fees)
- 57,000 mi (battery warranty 60,000 mi or 8 years)
- 27 kWh (28.3 kWh new)
- Fixed gear, no transmission
- 106 mi range at @65 mph
- 88 mi range on mid-grade gas @65 mph
It is an EV around to and from the nearest towns with highway privileges, ~36 MPG. Cross country is like a motorcycle with stopping every ~1.5 hours to top off the 2.3 gallon tank and drain the used coffee. Enclosed, there is no helmet, bugs, rain, cold, or heat in a comfortable four seater.
It is very hard to retro-fit any kind of EV drive into an ICE car. The body structure is wrong and inserting a 'power assist' has no friendly power take-off or add-shaft interface. The alternator/motor systems have been a mess and you're adding parts that always reduces reliability.
