Car and Driver checks out the world's fastest production car

http://www.caranddriver.com/reviews/2015-koenigsegg-one1-first-drive-review

Everything is going fine until we reach 150 mph. And then, very suddenly, it’s not.

Just sitting in the passenger seat of the Koenigsegg One:1 (we explain the silly name later) as it attacks a wet runway is, in terms of spiked adrenaline, somewhere between a solo sky dive and being chased by a bull while running in red pants. But as the man from the factory demonstrates, even in the sodden conditions we’ve found waiting for us in Sweden, the world’s fastest car can still be easily controlled. Or so it seemed.

It’s been raining all day, and the One:1 is struggling to put its monstrous power onto the slick surface of the former airbase that serves as Koenigsegg’s test track. The engine is bellowing and the car squirming and sliding as the twin-turbocharged V-8 comes on boost. Even with the stability control switched on and working overtime, it’s struggling to find grip. Running on regular pump gasoline means around 1161 horsepower; 1341 horses and 1011 pound-feet come when it’s fueled with E85. But either way, that’s vastly more twist than the rear Michelins can deliver to the soaked tarmac. Glancing across at the instrument display, I can see that the wheels only stop trying to spin as we pass 125 mph, when serious aerodynamic downforce starts to push the car into the track.
