Powertrain & Engine Architecture
The i4 M50 utilizes a dual-motor, all-wheel-drive (xDrive) powertrain. The front motor produces 258 hp and 365 Nm (269.21 lb-ft) of torque, while the rear motor generates 313 hp and 430 Nm (317.15 lb-ft) of torque. Combined, these motors deliver a peak output of 544 hp and 795 Nm (586.36 lb-ft). Both motors are synchronous electric motors, known for their efficiency and power density. The 83.9 kWh battery pack, positioned low in the vehicle floor, provides a usable capacity of 81.3 kWh. The battery employs lithium-ion technology and operates at a nominal voltage of 398.5V. The LCI update included improvements to battery management for increased range and faster charging times. The single-speed automatic transmission is inherent to electric vehicle drivetrains, providing seamless acceleration.
Driving Characteristics
The i4 M50 delivers exhilarating acceleration, achieving 0-60 mph in approximately 3.7 seconds. The instant torque availability characteristic of electric motors provides immediate responsiveness. The xDrive system intelligently distributes power between the front and rear axles, optimizing traction and stability in various driving conditions. Compared to the standard i4 eDrive40, the M50 offers a significantly more aggressive driving experience, with sharper throttle response and a more firmly tuned suspension. While the eDrive40 prioritizes efficiency and comfort, the M50 leans towards performance. The low center of gravity, thanks to the battery pack’s placement, contributes to confident handling and reduced body roll.
Equipment & Trim Levels
The i4 M50 comes standard with a comprehensive suite of features, including BMW’s iDrive 8 operating system with a curved display encompassing a 14.9-inch information display and a 12.3-inch control display. Standard interior appointments include Sensatec upholstery, sport seats, and ambient lighting. Optional extras include Vernasca leather upholstery, a Harman Kardon surround sound system, and advanced driver-assistance systems like the Driving Assistant Professional package. The M50 also benefits from M-specific styling cues, such as a unique kidney grille design, aerodynamic enhancements, and M Sport brakes.
Chassis & Braking
The i4 M50 features a sophisticated chassis design optimized for both performance and comfort. The front suspension utilizes a spring strut design with a transverse stabilizer, while the rear suspension employs an independent multi-link setup with air suspension and a transverse stabilizer. The air suspension allows for adjustable ride height and damping characteristics, enhancing both ride quality and handling. Braking duties are handled by ventilated disc brakes on all four wheels. The M Sport brakes, available as an option, offer increased stopping power and fade resistance.
Market Reception & Comparison
The i4 M50 has been generally well-received by automotive critics, praised for its impressive performance, refined interior, and long-range capability. Compared to the Tesla Model 3 Performance, the i4 M50 is often lauded for its more luxurious interior and more engaging driving dynamics. However, the Tesla benefits from a wider Supercharger network. Against the Porsche Taycan, the i4 M50 offers a more accessible price point, although the Taycan typically delivers a more focused and track-oriented driving experience. Fuel economy, expressed as MPGe, ranges from 96 to 119, depending on driving conditions.
Legacy
The BMW i4 M50 represents a significant step forward in BMW’s electrification strategy. The powertrain, while relatively new, has demonstrated good reliability in early reports. The combination of high performance, long range, and luxurious appointments positions the i4 M50 as a compelling alternative to established electric vehicles. As the used market matures, the i4 M50 is expected to hold its value well, particularly among enthusiasts seeking a premium electric Gran Coupe with a sporty driving character. The advancements in battery technology and charging infrastructure incorporated into the i4 M50 will likely influence future BMW electric vehicle designs.
