Powertrain & Engine Architecture
The i4 M50 utilizes a dual-motor, all-wheel-drive (xDrive) powertrain. Each motor employs synchronous excitation technology, known for its high efficiency and power density. The front motor produces 258 horsepower and 430 Nm (317 lb-ft) of torque, while the rear motor generates 313 horsepower and 365 Nm (269 lb-ft) of torque. Combined, these motors deliver a total output of 544 horsepower and 795 Nm (586 lb-ft) with Sport Boost activated. The 83.9 kWh battery pack, positioned low in the vehicle floor, provides a usable capacity of 80.7 kWh. BMW’s integrated cooling system manages the battery and powertrain temperatures, optimizing performance and longevity. The single-speed automatic transmission delivers power to all four wheels. The car supports DC fast charging at up to 150 kW, allowing for a 10-80% charge in approximately 31 minutes.
Driving Characteristics
The i4 M50 offers exhilarating acceleration, achieving 0-60 mph in approximately 3.7 seconds. The instant torque delivery characteristic of electric motors provides a responsive and engaging driving experience. The xDrive system intelligently distributes power between the front and rear axles, optimizing traction and stability in various conditions. Compared to the i4 eDrive40, the M50 exhibits a noticeably firmer suspension setup and more aggressive throttle mapping. While the eDrive40 prioritizes efficiency and comfort, the M50 leans towards a more performance-oriented feel. The low center of gravity, thanks to the battery pack’s placement, contributes to confident handling and reduced body roll. Regenerative braking is adjustable, allowing drivers to customize the level of deceleration when lifting off the throttle.
Equipment & Trim Levels
The i4 M50 came standard with a comprehensive suite of features, including BMW’s Curved Display – a 12.3-inch information display and a 14.9-inch control display merged into a single unit. Other standard equipment included sport seats, a panoramic sunroof, premium audio system, and a full suite of advanced driver-assistance systems (ADAS) such as lane departure warning, automatic emergency braking, and adaptive cruise control. Optional extras included Vernasca leather upholstery, M Sport package (adding more aggressive styling elements), and Driving Assistance Professional package (enhancing ADAS functionality). Interior trim options included various wood and carbon fiber accents.
Chassis & Braking
The i4 M50 features a MacPherson strut front suspension and a multi-link rear suspension, with air suspension available as an option on the rear axle. The air suspension provides adjustable ride height and damping characteristics, enhancing both comfort and handling. Braking duties are handled by ventilated disc brakes on all four wheels. The M50 benefits from a more robust braking system compared to the eDrive40, featuring larger rotors and calipers to cope with the increased performance. The electronic power steering system offers precise and responsive steering feel.
Market Reception & Comparison
The i4 M50 was generally well-received by automotive critics, praised for its impressive acceleration, refined handling, and luxurious interior. However, some reviewers noted that the ride quality could be firm on rough roads, even with the optional air suspension. Compared to the i4 eDrive40, the M50 offered a significant performance upgrade but at the cost of slightly reduced range. Against competitors like the Tesla Model 3 Performance, the i4 M50 was often lauded for its more premium interior and more engaging driving dynamics, while the Tesla offered a more extensive charging network. The Porsche Taycan, while more expensive, provided a more focused and track-capable driving experience.
Legacy
The BMW i4 M50 established BMW as a serious contender in the high-performance electric vehicle market. The powertrain, while complex, has proven relatively reliable in early ownership reports. The i4 M50’s success paved the way for further electric performance models from BMW. On the used car market, the i4 M50 holds its value well, reflecting its desirable combination of performance, luxury, and technology. The battery’s longevity remains a key consideration for potential buyers, but BMW’s battery warranty provides some peace of mind. The i4 M50 represents a significant step in BMW’s transition towards electrification, showcasing the brand’s ability to deliver a compelling electric driving experience without sacrificing its core values of performance and luxury.
