Overview of the BMW I3
As you consider the BMW i3, you’ll notice it’s a car that stands out due to its unique features and design.
The BMW i3 is a funky-looking electric car that debuted ahead of its time, offering an odd 2+2-door configuration and eco-conscious interior panels made from hemp-reinforced plastics.
Its carbon-fiber passenger cell sits atop an aluminum skateboard platform that houses the suspension, motor, battery, and, in the REx version, a small two-cylinder petrol engine.
This setup powers the rear wheels, making the i3 both visually distinctive and innovative in structure.
Powertrain Variations
As you delve into the powertrain variations of the BMW i3, you’ll find that it’s equipped with a single electric motor driving the rear wheels, providing impressive torque.
The i3s offer a power boost, delivering 181 horsepower compared to the standard model’s 170 horsepower.
Additionally, the Range Extender (Rex) version includes a small engine similar to those used in BMW scooters, which adds about 70-80 miles of range to the car’s electric capability.
Powertrain Variations
In the BMW i3 lineup, how do you choose the right powertrain to suit your needs?
It depends on your preferences for range, performance, and handling.
Some key options include:
- Pure electric model with 170 hp.

Electric Motor
The BMW i3’s electric motor is a key component of its powertrain variations, offering different levels of performance across its models.
You’ll notice the motor drives the rear wheels, providing a nimble feel typical of electric vehicles.
The standard i3 delivers 170-hp, while the i3s variant offers slightly more power.
Both models use a hybrid synchronous motor, ensuring efficient energy use and good acceleration.
This setup makes the i3 well-suited for city driving, thanks to its responsive torque delivery.
Range Extender
BMW’s innovative Range Extender (REx) model offers a practical solution for those needing more distance from their i3.
The REx pairs a small gas engine from a BMW scooter to act as a generator when the battery is low, adding 70-80 miles of range.
Key features include:
- Heavier weight and slightly reduced speed versus all-electric i3
- Lightweight curb weight under 3000 pounds maintains agility
- 184 lb-ft torque for responsive driving in traffic
- Low maintenance with just a yearly $139 oil change
- Available on select trims like the 2018 i3s REx with a 27.2-kWh battery priced around $24,759
This setup balances electric driving with extended range flexibility.
Value Retention and Pricing
When buying a used BMW i3, you’re likely looking at a vehicle that holds its value relatively well compared to other luxury electric cars.
The 2019-21 i3s fetch over $30,000, making them a good investment for those seeking a used electric vehicle. Well-used early models can be more affordable, with clean cars selling in the teens.
For instance, a 2015 model might start at $16,598, while a 2020 model costs around $28,763, offering good value for a more modern used BMW i3.
The 2015 model provides an affordable entry into the used electric vehicle market.
Problem Areas and Common Issues
When you’re evaluating a BMW i3, be aware of common issues such as electrical system failures, which can stem from problems like a worn-out 12V battery or faulty modules like the Electric Motor Electronics (EME) module.
Suspension component wear is another area to examine closely, particularly in the front strut bearings and motor mounts.
Additionally, you might encounter defects in interior accessories, including issues with the navigation system and other electrical components that can lead to frustrating malfunctions.
Electrical System Failures
As you excavate into the electrical system of the BMW i3, you’ll find several problem areas that can impact your driving experience.
