The Lamborghini Aventador LP 700-4 was introduced in 2011 as the brand flagship V12 supercar, replacing the Murcielago. Its naturally aspirated 6.5 litre engine became famous online not just for speed but for its theatrical cold start, which is louder and sharper than most modern supercars. Clips of that startup were shared across car forums, YouTube compilations and soundboards, and streamers later adopted short cuts like this one as alerts and intros. It remains popular because even listeners who never see the car instantly recognise the exotic, high value image it creates.
