The BMW i4 xDrive40 presents a significant upgrade compared to its predecessor, the 430i. This electric vehicle (EV) showcases impressive figures with a power output of 395 horsepower (295 kW) and 442 lb-ft (600 Nm) of torque, coupled with a starting price of $62,300. This positions the i4 as a more potent and pricier option within BMW’s line-up.
One of the standout features of the i4 is its use of BMW’s fifth-generation electric motors. Unlike many automakers that opt for permanent magnets, BMW utilizes electrically excited synchronous motors. In terms of performance, the front motor is rated at 255 horsepower (190 kW) and 243 lb-ft (330 Nm), while the rear motor boasts 308 horsepower (230 kW) and 295 lb-ft (400 Nm). These motors draw power from an 84 kWh battery pack, with 81 kWh being usable, enabling the vehicle to achieve an EPA-rated range of 287 miles (462 km) when equipped with 18-inch wheels.
Opting for 19-inch wheels, as seen in some test models, results in a slightly reduced EPA range of 269 miles (432 km). For those prioritizing longer distances, the single-motor eDrive40 variant, when fitted with 18-inch wheels, can achieve an impressive range of 318 miles (511 km), illustrating how wheel size and motor configuration significantly influence range efficiency.
An interesting aspect of the i4’s design is the easy transition between driving modes. Drivers can shift between regenerative braking when lifting the throttle by using a simple lever located on the center console. This feature lets the car either slow down and recover energy through regenerative braking or coast freely. Regardless of the selected mode, the vehicle employs regenerative braking when the brake pedal is pressed, efficient enough to achieve up to 0.3 G of deceleration before relying on traditional friction brakes.
Performance-wise, the i4 offers rapid acceleration, capable of reaching 62 mph (100 km/h) from a standstill in just 5.1 seconds. While this may not be extraordinary by car enthusiast standards, it is more than enough for everyday driving needs, enabling smooth merges and overtaking maneuvers.
During testing, the i4’s real-world range slightly fell short of official EPA estimates. Despite experiencing a milder winter, temperatures hovered around freezing during the evaluation week, leading to an average efficiency of 3.1 miles per kWh (20 kWh/100 km). Interestingly, toggling between Sport and Eco driving modes did not substantially affect energy consumption, even over various driving conditions, including urban streets and highways.
In summary, the BMW i4 xDrive40 represents a remarkable step forward in electric vehicle technology for the brand. With its promising performance, innovative motor technology, and the flexibility of driving modes, it appeals to both fans of the brand and potential EV buyers looking for a blend of efficiency and dynamic driving capabilities. Whether it’s the impressive power or the thoughtful engineering that defines its electric motors, the i4 showcases BMW’s commitment to shaping the future of driving.
