The most shocking thing about watching from the passenger seatof a car going from zero to 300 kilometers an hour (186 mph) isn’tthe sight of the world whipping by at a frightening rate — it’s thesound. Koenigsegg first broke therecord for the time taken to accelerate to such a speedand come to a stop again back in June, cranking its KoenigseggOne:1 “megacar” to 300 kph and back down to zero in 17.95 seconds,but the video of the Swedish supercar manufacturer’s feat wasoverlaid with trancey synth pop that stopped us being able to hearthe engine. A few days later Koenigseggreleased a new version of the video, an appropriately titled”Full-noise edition,” that lets us hear every sound from inside thecar.
And an impressive sound it is too. The One:1’s 5-liter V8dual-turbo engine bucks and wails as it rips through gear changes,making it sound like an unholy combination of something you’d drivein a Formula 1 race and a muscle car, high-pitched top end joinedby a throaty roar that cuts out for milliseconds betweentransmission shifts. Koenigsegg’s One:1 is so named for its paritybetween power output and weight — it’s capable of 1,360 PS (theGerman measurement for horsepower), offsetting its lightweight1,360-kilogram (2,998-pound) construction.
