# 2013-2016 BMW i3 REx 60 Ah The BMW i3 REx is a pioneering urban electric vehicle featuring a small gasoline "range extender" engine that generates electricity when the 60 Ah battery depletes. With approximately 72 miles of electric range and an additional 80 miles from the REx, it addressed early EV range anxiety. Reviewers praise its futuristic carbon-fiber construction, nimble handling, and unique interior with sustainable materials. However, the cramped rear seats, firm ride, and limited REx fuel tank (1.9 gallons, legally restricted) draw criticism. It's infamous for its polarizing styling and the REx's limited utility—it can't maintain highway speeds indefinitely under gasoline power alone. **Best for:** Urban commuters and eco-conscious drivers seeking a premium city car with backup range. The limited overall range makes it less suitable for frequent long-distance travel.
The i3 REx combines electric drivetrain with a small gas range extender. Battery degradation is relatively minimal. The REx engine requires infrequent but specialized maintenance. Depreciation was steep initially but has stabilized. Insurance costs are moderate despite being a BMW. Carbon buildup in the REx engine occurs if not exercised regularly with sustained highway driving.
