Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQB offers optional Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Polestar 3 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.

Both the EQB and the Polestar 3 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available lane departure warning systems and around view monitors.

Warranty

There are over 12 times as many Mercedes dealers as there are Polestar dealers, which makes it much easier should you ever need service under the EQB’s warranty.

Reliability

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Mercedes vehicles are better in initial quality than Polestar vehicles. With 110 fewer problems per 100 vehicles, JD Power ranks Mercedes higher than Polestar.

Fuel Economy and Range

On the EPA test cycle the EQB gets better mileage than the Polestar 3:

			MPGe

	AWD	300 Electric Motors	89 city/85 hwy
		350 Electric Motors	89 city/85 hwy

	AWD	20" Wheels Dual Electric Motors	91 city/82 hwy
		22" Wheels Dual Electric Motors	84 city/76 hwy
		Performance Package Electric Motors	81 city/73 hwy

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the EQB can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Polestar 3 doesn’t offer run-flat tires.

Suspension and Handling

The EQB’s drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The Polestar 3 doesn’t offer drift compensation steering.

Chassis

The Mercedes EQB may be more efficient, handle and accelerate better because it weighs about 1050 pounds less than the Polestar 3.

The EQB is 8.5 inches shorter than the Polestar 3, making the EQB easier to handle, maneuver and park in tight spaces.

The EQB is 5.3 inches narrower than the Polestar 3, making the EQB easier to handle and maneuver in traffic.

Passenger Space

The EQB offers optional seating for 7 passengers; the Polestar 3 can only carry 5.

Cargo Capacity

The EQB’s cargo area provides more volume than the Polestar 3.

	EQB	3
Third Seat Folded	22 cubic feet	n/a
Third Seat Removed	25.9 cubic feet	17.1 cubic feet
Second Seat Folded	61.8 cubic feet	50 cubic feet

A low lift-over cargo hatch design makes loading and unloading the EQB easier. The EQB’s cargo hatch lift-over height is 28.5 inches, while the Polestar 3’s liftover is 31 inches.

Ergonomics

The EQB’s power mirror controls are mounted on the armrest for easy access. The Polestar 3’s power mirror controls are embedded in the infotainment system, seriously distracting drivers who have to adjust them while driving.
