Throwback to the first time we heard the sound of the 1800-hp #Bugatti Tourbillon accelerate past 400 km/h. Since then Mate Rimac has shared a handful of sound clips to his Instagram grid and Stories, and it’s safe to say the Tourbillon has an unforgettable sound. Just 250 will be built, all starting at an eye-watering $4.6 million. #BugattiTourbillon #Tourbillon #hypercar #acceleration #sound #carsofinstagram #cargram #roadandtrack
