From the July/August 2023 issue of Car and Driver.
BMW’s funky-looking electric i3 never really caught on in the U.S. Its best sales year was 2015, when slightly more than 11,000 of the EVs (including the REx model, the one with the optional range extender) found homes. And yet, its odd looks and practical shape would fit right in with today’s electric cars.
The i3 may have wheels that look like pizza cutters, but there’s nothing cut-rate about it. A carbon-fiber passenger’s cell rides on an aluminum skateboard that carries the suspension, a single motor driving the rear wheels, the battery, and, in the REx version, a small engine borrowed from a BMW scooter. Equally odd is the 2+2-door configuration, and instead of typical materials, interior panels are hemp-reinforced plastics showing off a random fiber pattern.
Ahead of its time when new, an i3 today makes a remarkably affordable pre-owned second car. BMW never gave the i3 a long-range battery. Its smallest battery, found in the 2014–16 i3, offers 81 miles by the EPA’s measure, and its largest, in 2019–21 models, hits 153. If you can live with that kind of range, you’ll love an i3.
Powertrain
All i3 models are motivated by a 170-hp AC motor. In 2018, BMW added an i3s variant, which upped power to 181 horses and came with a firmer suspension tune. Battery size grew twice. After launching with an 18.8-kWh pack, the i3 got a 27.2-kWh pack for 2017 and then a 37.9-kWh unit for 2019. The electric motor has enough torque, 184 pound-feet (199 for the i3s), to feel fleet in traffic, thanks to a curb weight under 3000 pounds. We recorded a sub-seven-second 60-mph time in 2014. The heavier REx, with its 647-cc two-cylinder engine and generator, is a bit slower but gets you a 1.9-gallon safety net (2.3 gallons starting in 2017) that adds another 70 to 80 miles of range.
Value
Because the i3 got a steady flow of running changes (and because these cars are the newest), the 2019–21 i3s have the highest value and can fetch over $30,000. Well-used early models flirt with four-digit pricing, but a clean car with moderate mileage should sell in the teens. DC fast-charging capability was optional in 2014 and standard from 2015, so first-year models without it sell for less.
Problem Areas
Buying an EV with a bad battery is a costly error. Inspect an i3 when the battery is fully charged. If the indicated range is significantly less than the EPA label value, move along. But an eight- or nine-year-old i3 with an indicated max range still in the 70s is probably okay. Pre-2018 cars suffered from drive-bearing failures, which are audible at parking-lot speeds; models from 2018 on have updated bearings. If you value connectivity, avoid early cars (some 2017s and prior), which have obsolete 3G communications. With the REx, ask how often its oil was changed, and even take a look at and smell the oil on its dipstick.
