Compare the2024 BMW i4VS 2023 Tesla Model S

The i4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model S doesn’t offer pre-crash pretensioners.

The i4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Model S doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

Over 200 people are killed each year when backed over by motor vehicles. The i4 offers an optional Active Park Distance Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Model S doesn’t offer backup collision prevention brakes.

The i4 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Model S only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

To help make backing out of a parking space safer, the i4’s standard Cross Traffic Warning uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model S doesn’t offer a rear cross-path warning system.

The i4 has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the i4 and the Model S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and driver alert monitors.

BMW pays for scheduled maintenance on the i4 for 3 years and 36,000 miles. BMW will pay for tire rotations, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Tesla doesn’t pay scheduled maintenance for the Model S.

There are over 2 times as many BMW dealers as there are Tesla dealers, which makes it much easier should you ever need service under the i4’s warranty.

To make loading groceries and cargo easier when your hands are full, the i4’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Model S doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

A maintenance reminder system is standard on the i4 to save the owner time and money by calculating maintenance intervals for brake fluid replacement and vehicle inspections based on odometer mileage. This takes the guesswork out of keeping your vehicle in top condition and helps it last longer. Tesla doesn’t offer a maintenance reminder on the Model S.

The i4’s entire steering wheel hub sounds the horn, facilitating hitting the horn in an emergency. The Model S has a small, single button on the steering wheel spoke that can be hard to find quickly in an emergency.

The i4 offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Model S doesn’t offer a heads-up display.

The i4’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Model S’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The i4’s standard side window demisters help clear frost or condensation from the side windows in the winter. The Model S doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the i4 has standard extendable sun visors. The Model S doesn’t offer extendable visors.

The i4 is available in both rear-wheel drive and all-wheel drive configurations. The Model S doesn’t offer a two-wheel drive configuration.
