BMW i4 rescue in Descanso, CA.
The climb into the mountains near Julian tests the i4's range hardest, especially in the M50 trim, and it's one of our longest drives if a BMW strands out here. Fast charging is a long way off, so we usually add more than one charge block.
Rescuing a BMW i4 in Backcountry San Diego
The climb into the mountains near Julian tests the i4's range hardest, especially in the M50 trim, and it's one of our longest drives if a BMW strands out here. Fast charging is a long way off, so we usually add more than one charge block.
Descanso tucks into the hills off the 8, far from fast charging. A few charge blocks are usually needed to reach the nearest one. Expect a higher total plus a longer arrival window.
Why a BMW i4 strands
The i4 shares 12V battery management quirks common to BMW's electrical architecture, and the sportier M50 trim's extra power draw can catch drivers off guard on range, especially compared to the more efficient eDrive40.
The charge port is on the driver's side rear fender, in roughly the same spot BMW uses for a fuel door on its gas models, and it's a fully electronic release.
How we get your BMW i4 moving in Descanso
- We run our truck's NACS outlet through a J1772 adapter to connect with the i4's charge port.
- We jump the 12V system first when it is down, then confirm the high-voltage side wakes before adding range.
- Three or more 15-minute blocks add 30-plus miles to reach a distant charger. Out in Descanso an extra block is common before the nearest fast charger.
BMW i4 range and the drive out of Descanso
EPA range runs from about 227 miles on the M50 to 301 miles on the eDrive40, and the performance trim's extra power costs real range on hilly routes.
