2023 BMW i4 Evaluation, Pricing, and Specs

We prefer the higher-performance M50 over the less expensive—and less powerful—eDrive35 and eDrive40 trims. The M-badged model comes standard with a more assertive appearance, including 19-inch wheels. It also has a beautifully tuned suspension that revels in aggressive driving but is calm and comfortable around town. Upgraded brakes with blue calipers are also included on the M model. We like the look of the optional 20-inch rims and the improved performance of their wider, stickier tires, but they drop the M50’s estimated driving range from 270 to 227 miles. We’d enhance the interior with one of the vernasca leather options, the Premium package (ambient interior lighting, heated seats and steering wheel, lumbar support), and individual options such as the adaptive LED headlights, ventilated front seats, Harman Kardon sound system, and wireless charging.

EV Motor, Power, and Performance

The 2023 i4 feeds electrons to either one or two electric motors, depending on the model. The eDrive35 is one of two single-motor rear-drive options using a 281-hp unit. The eDrive40 features a single motor on the rear axle that makes 335 horsepower. The M50 has an electric motor on both axles, which together provide all-wheel drive and produce 536 horsepower and 586 pound-feet. The M50 we tested hit 60 mph in 3.3 seconds, which is quicker than a rear-drive M3 Competition. The rear-drive i4 rolls on a standard set of 18-inch rims; 19-inchers are optional. Conversely, the all-wheel-drive M50 is fitted with either 19s or 20s, and it has adaptive dampers and a variable-ratio steering system. The i4 M50 that we drove delivered immediate and forceful thrust, and even though it weighs considerably more than an M3, its lower center of gravity helps it move assuredly and gracefully.

Range, Charging, and Battery Life

BMW says the single-motor rear-drive i4 eDrive40 can travel up to around 300 miles on a full battery. The dual-motor all-wheel-drive M50 has the same 81.5-kWh battery, but its claimed range tops out at 245 miles. These i4 models have a 200-kW charging capacity that can add between 88 and 108 miles in just 10 minutes. The entry-level eDrive35 model comes with a smaller 66.0 kWh net capacity battery, which is said to deliver around 260 miles of range and maxes out at 180-kW charging speeds. Using the Level 2 (up to 11 kW) onboard charger, the i4 can recharge its battery from zero to 100 percent in less than 8 hours.

Fuel Economy and Real-World MPGe

According to the EPA, the most efficient i4 model is the eDrive40 with standard 18-inch wheels. That model earned ratings of 109 MPGe city and 108 MPGe highway. Adding the larger 19-inch wheels drops those figures slightly, and the more powerful M50 model is rated lower too. While we haven’t put every i4 through our 75-mph highway route, which is part of our extensive testing regimen, to determine its real-world efficiency, an i4 eDrive 40 Gran Coupe we tested scored 280 miles of range. Just two miles short of its EPA estimate. For more information about the i4’s efficiency ratings, visit the EPA website.

Interior, Comfort, and Cargo

Inside, the i4’s cabin is richly appointed, including the availability of rose gold trim, white leather upholstery, and light wood trim. The general layout is similar to other BMW models, but the i4, in addition to the all-electric iX SUV, is the first to have a massive, seamless display that spans almost two-thirds of the dashboard. The four-door i4 has a dramatic rear roofline that imitates a coupe-like profile, but it has a traditional trunk in the back.

Infotainment and Connectivity

The i4 was one of the first BMWs to feature the company’s iDrive 8 infotainment and connectivity software, called iDrive 8. Thanks to a free over-the-air update, the i4 gets upgraded to a newer version, iDrive 8.5. The system operates through a 14.9-inch touchscreen integrated with a 12.3-inch digital instrument panel on a huge curved display on the dashboard. Along with a rotary controller on the center console, the system offers advanced voice commands and myriad popular features. These include Apple CarPlay, Android Auto, and a Wi-Fi hotspot.

Safety and Driver-Assistance Features

The 2023 i4 offers a variety of standard and optional driver-assistance technology. For more information about the Bimmer’s crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

• Standard forward-collision warning and automated emergency braking
• Standard lane-departure warning and lane-keeping assist
• Available adaptive cruise control with stop-and-go technology
