A New Era for the BMW i3: Beyond the City Car
BMW’s i3 is undergoing a transformation, stepping away from its origins as a compact city car and evolving into a more conventional saloon design. The original i3, introduced in 2013, boasted a futuristic, carbon-constructed design and chic interior, but its production concluded in 2022 after reaching a milestone of 250,000 units. While the new i3 adopts a traditional three-box saloon shape, it remains at the forefront of automotive technology.
A Sibling to the iX3
The new i3 shares its lineage with the acclaimed TopGear Car of the Year iX3. As part of BMW’s Neue Klasse lineup, this marks a significant shift for the 3 Series. Entirely electric, the i3 features BMW’s innovative ‘superbrains’ that enhance infotainment, automated driving, in-cabin comfort, and vehicle dynamics, offering 20 times the computing power of its predecessors while reducing cabling by 600 meters.
Innovations Under the Hood
The i3’s dynamics are controlled by the ‘Heart of Joy’ processor, which integrates the electric motors, brakes, steering, and stability control, offering faster response times. Developed entirely in-house, this technology is set to become a staple in BMW’s future models.
Design and Performance Insights
While the final design is under wraps until later this month, the Vision Neue Klasse concept gives a glimpse of the future. The i3’s dimensions are similar to the G20 3 Series, with a longer wheelbase and shorter overhangs. The initial model, the i3 50 xDrive, will feature twin motors, all-wheel drive, and a powerful 463bhp output, sharing a 109kWh battery with the iX3 but promising an extended range thanks to its aerodynamics.
Winter Testing in Arjeplog
The i3 has undergone rigorous testing at BMW’s winter facility in Arjeplog, showcasing its dynamic handling on icy terrains. Despite its two-tonne weight, the i3 feels agile, with precise steering feedback and Sport mode enhancing its rear-drive characteristics. The electric motors deliver ample power, ensuring a smooth driving experience.
Efficient Braking and Stability
The Heart of Joy excels in braking, with approximately 95% of deceleration managed by electric motor regeneration. This integration provides a consistent pedal feel, even under ABS activation. The processor also manages stability, offering impressive control during ice braking tests and ensuring seamless stops with the ‘soft stop’ functionality.
Ride Quality and Handling
The i3 opts for a passive spring and damper setup, maintaining minimal body roll through corners. While the ride is firm, it remains comfortable, and the cabin is notably quiet once the synthetic sound is disabled. In Dynamic Traction Control mode, the i3 demonstrates its sporty nature with controlled slides on icy surfaces.
Interior and Future Variants
BMW’s new Panoramic iDrive system, with its expansive display, dominates the interior, replacing traditional instrument clusters. Rear seating offers adequate leg and headroom, though taller passengers may find foot space limited. The i3, primarily electric, will have petrol and hybrid versions, incorporating Neue Klasse aesthetics with current 3 Series technology.
Performance Prospects
Looking ahead, the M division is developing both petrol and electric M3 models, with the latter anticipated to feature quad motors and potentially over 1,000bhp. With innovations like simulated gearshifts, the Heart of Joy will play a crucial role in managing the vehicle’s enhanced performance capabilities.
