What is the saying? "It's all fun 'till someone gets hurt." I don't know for sure the status of the driver (I have heard they survived) but the second picture is all they were able to salvage of the car.
A Hellcat can put out 700 hp when you use the red key. For comparison a NASCAR Sprint Cup engine puts out about 800-900 hp. The old supercharged "Offys" of Indy fame back in the day were around 1,000 hp.
A Bugatti Chiron produces around 1,500 hp. Top speed 261 MPH (420 km/h). I once said about the Chiron "It will give you an orgasm... or kill you."
(Just heard that Floyd Mayweather has to sell his Bugatti. Maybe I can buy it from him? )
