I got an i3 with a range extender and a 2 gallon gas tank. The gas tank range can't exceed the battery range and still be an EV. I use the battery almost all the time but knowing I can gas and go 80 miles is great. I drove 1,400 miles to Florida and back. It wasn't noticeably worse experience than an ICE.
- bumby 3y agoI'm curious if they recommend purging the tank (or using the gas) periodically? Gas does expire.
- avidiax 3y agoThey have a maintenance cycle that forces the engine to run sometimes. That uses up some of the fuel and keeps all the parts lubricated.

- detourdog 3y agoIt depends on the model year/battery size. That was a US only implementation and as you know there is a work around. The other European feature that should be available in the USA is the ability to set when the REX starts to kick in. The USA requires the REX to kick in at 6% charge. The problem at that level is that the battery can't compensate during short high power drawls. There is a cheat code that enables the REX to kick in a 25% charge remaining. This seems to provide more on demand amperage but I'm not sure what is happening. Hills and wind have a larger effect on speed when off the REX. The REX is just a tiny motor that maintains the battery level but doesn't connect directly to the electric drive train.
