A BMW driver was left shaken after pulling a hidden switch in her car and nearly flying out of her chair.
TikTok creator Becca Taylor filmed herself testing the feature and shared the video online, sending motorheads everywhere into a tizzy.

The nine-second clip started with a close-up shot of a black and red paddle labelled “boost” and text that read: “Oooo what does this button do?”
It then cut to a shot from behind the steering wheel, with a BMW logo at its centre, where moving scenery indicated the car was in motion.
Becca, whose TikTok handle is @driving_bex, was then shown driving the car, smiling ahead, before pulling the “boost” paddle.
Her face was transformed by shock: her eyebrows shot up, her hair blew back, her shoulders rose up, and her smile disappeared.
But she quickly recovered and resumed her pre-“boost” disposition, grinning ear to ear.
The caption beneath the video read: “Everyone loves a boost button.”
Popular TikTok account @automotorundsport wrote beneath the clip: “mega reaktion”, to which Becca said: “Thank you.”
Another user wrote: “Your face says it all.”
The BMW i5 car Becca was driving comes equipped with a boost mode which helps drivers overtake with ease by providing short bursts of power, as captured in the TikTok video.
A driver engages “sport boost mode” by pulling the paddle for more than 0.8 seconds.
Doing so in a BMW i5 eDrive40 car can temporarily increase torque to 317 pound-feet, adding some spice to the driving experience.
The total torque of a BMW i5 M60 xDrive, which has been described as eDrive40’s “brawny and exciting older brother”, can be bumped up to 605 pound-feet when its boost mode is engaged.
BMW i5 cars cost between about £74,100 and £109,900, according to topgear.com.
The eDrive40 is rear-drive only and can drive 62mph in six seconds flat, with a top speed limited to 120mph.
Meanwhile, the all-wheel drive M60 xDrive can travel 62mph in 3.8 seconds with a top speed of 143mph.
