Powertrain & Engine Architecture
The 2017-2018 i3 facelift utilized a single, rear-mounted synchronous electric motor producing 170 horsepower and 250 Nm (184 lb-ft) of torque. This motor, designated IB1P23M0, delivered its peak power at 4800 rpm and maximum torque instantly, a characteristic of electric motors. The 33.2 kWh lithium-ion battery pack, positioned low in the vehicle’s floor, provided a usable capacity of 27.2 kWh. The battery management system (BMS) was crucial for optimizing battery life and performance, monitoring cell voltages, temperatures, and state of charge. The i3 featured a single-speed automatic transmission, simplifying the driving experience and maximizing efficiency. Regenerative braking, capable of up to 50 kW of recuperation, further enhanced range by converting kinetic energy back into electricity during deceleration.
Driving Characteristics
The i3 33.2 kWh offered a noticeably improved driving experience compared to earlier iterations with smaller battery packs. Acceleration from 0-60 mph took approximately 6.9 seconds, making it brisk for a compact city car. The instant torque delivery of the electric motor provided responsive acceleration, particularly at lower speeds. The rear-wheel-drive configuration contributed to a unique handling balance, although it required some acclimation for drivers accustomed to front-wheel-drive vehicles. The single-speed transmission meant there were no gear changes, resulting in smooth and linear acceleration. While not designed for high-speed cruising, the i3 felt stable at highway speeds, although range diminished significantly at higher velocities.
Equipment & Trim Levels
The i3 with the 33.2 kWh battery was typically offered with a generous level of standard equipment. This included features like automatic climate control, a 6.5-inch infotainment system with navigation, BMW ConnectedDrive services, and a suite of safety features such as lane departure warning and collision mitigation. Interior upholstery was typically a combination of cloth and recycled materials, reflecting BMW’s commitment to sustainability. Optional extras included larger infotainment screens, premium audio systems, leather upholstery, parking assist, and adaptive cruise control. The “Deka” interior trim was a popular option, featuring contrasting stitching and unique surface materials.
Chassis & Braking
The i3’s chassis was a defining feature, utilizing a CFRP passenger cell bonded to an aluminum drive module. This construction resulted in a remarkably lightweight vehicle, contributing to its efficiency and agility. The front suspension employed a McPherson strut design, while the rear featured a multi-link setup. Both front and rear brakes were ventilated discs, providing adequate stopping power. The electric power steering offered precise and responsive control. The relatively low weight of the vehicle meant that the braking system didn’t require excessive force to bring the car to a halt.
Market Reception & Comparison
The 2017-2018 i3 facelift was generally well-received by critics, who praised its innovative design, engaging driving dynamics, and improved range compared to earlier models. However, some criticisms remained regarding its limited rear passenger space and unconventional rear door configuration. Compared to other electric vehicles of the time, such as the Nissan Leaf and Volkswagen e-Golf, the i3 offered a more premium driving experience and a more distinctive design. Its fuel economy, measured in MPGe, was competitive with other EVs, and its reliability proved to be generally good, although battery degradation remained a concern for some owners.
Legacy
The BMW i3 33.2 kWh played a crucial role in establishing BMW as a leader in electric vehicle technology. It demonstrated the viability of CFRP construction in mass production and paved the way for future electric models from the brand. On the used car market, these i3s remain relatively sought after, particularly those with well-maintained batteries. While battery degradation is a factor to consider, the i3’s unique design, engaging driving dynamics, and commitment to sustainability continue to appeal to a niche but dedicated group of buyers. The powertrain, while not without its limitations, has proven to be reasonably durable, and parts availability remains good.
