2019 BMW i3

The 2019 BMW i3 is a unique electric vehicle known for its distinctive styling, agile handling, and use of lightweight materials like carbon fiber reinforced plastic (CFRP) in its construction. The standard i3 features a fully electric powertrain, while the i3 with Range Extender (REx) adds a small gasoline engine to act as a generator, extending the car’s range. The electric motor in the 2019 i3 produces around 170 horsepower and 184 lb-ft of torque, offering quick acceleration and a fun driving experience in urban environments. Some owners appreciate the i3 for its eco-friendliness, innovative design, and nimble handling. Common complaints include limited range (especially in the standard model), a firm ride, and polarizing styling. The REx model adds complexity and potential maintenance concerns related to the small gasoline engine, though the range is increased.
