How to Open the Trunk of a BMW i8?

Methods to open the trunk of a BMW i8: Press and hold the trunk release button on the remote key to open the trunk, or press the trunk switch on the A-pillar inside the car. As long as the trunk is not locked, it can be opened when the car is parked. The BMW i8 is a sports car, so the trunk space is very limited. The BMW i8 is equipped with a high-performance hybrid system, highlighting the vehicle's exceptional power performance. The plug-in hybrid system consists of two electric motors and a turbocharged gasoline engine, with a maximum output of 345 kW and a peak torque of 800 Nm. The 1.5-liter three-cylinder gasoline engine features direct fuel injection and variable intake turbocharging technology, delivering power to the rear wheels.
When I drive my BMW i8, opening the trunk is actually quite simple. After parking, just press the button on the key, and the trunk automatically pops open. Alternatively, inside the car, there's a trunk icon button near the driver's door—just reach out and press it for convenience. Some trim versions even come with a kick sensor feature; a gentle kick under the rear bumper's sensor area will open the trunk. However, be mindful of the key battery level—if it's too low, the function may fail. In humid weather, the sensor might be less responsive, so I often use the key method to avoid hassle. For safety, ensure the car is stationary and the engine is off before opening the trunk to prevent accidents. Regular cleaning of the sensor area helps maintain quick responsiveness—my car still works smoothly after years of use, and adding some lubricant can enhance durability.
From a technical perspective, opening the BMW i8 trunk primarily relies on an electric motor. The key remote signal triggers the unlocking mechanism, or the in-car button directly controls the motor to operate the tailgate. The high-end version is equipped with sensors, with the detection zone located beneath the rear of the vehicle—approaching and gently kicking the area activates it. If it fails to open, inspection points include checking the fuse, sensor cleanliness, or the need to reset software settings (e.g., selecting the reset function in the menu). It is advisable to avoid operation during movement or in rainy conditions, as the motor is susceptible to moisture. For maintenance, inspect and lubricate the electric components quarterly to prevent wear-induced response delays or excessive noise. This practice extends service life and ensures reliable trunk operation.
