Reviews of the BMW i3 REx are rather limited in number compared to those of the fully electric BEV i3.
Here MotorTorque tests the BMW i3 REx.
As MotorTorque states:
"This model, the pricier range extender version, promises a range of 180 miles - eighty miles more than the pure electric version."
"There's lots of neat touches here like satnav which shows you charging points in a hundred mile radius, and there's the option to switch to petrol mode and conserve the electric range."
"You'll only find two seats in the back and the boot is okay at 300 litres but doesn't offer the same practicality as a conventional family hatchback."
So, some pluses and some minuses. Check out the video for more on MotorTorque's i3 REx test drive review.
