Swedish hypercar is one the fastest, most powerful and most expensive cars ever produced, with the trump card of having one horsepower for every kilogram it weighs. So just how good is it? You could be forgiven for thinking that the Koenigsegg One:1 was designed as an internet-breaking meme as much as a car.The performance claims are hard to compute. Koenigsegg says it can go from 0-250mph in 20 seconds, and it recently proved it could go from 0-186mph-0 in just 17.95sec.The name sums up the car. The name is meant to said as 'one-to-one', as an expression of its perfectly balanced power-to-weight ratio of one metric horsepower to one kilogram of mass (or 986bhp per tonne).That’s when the twin-turbocharged 5.0-litre V8 engine is running on its favoured diet of E85 Ethanol, which is freely available in Sweden. Running on regular super-unleaded – as we are today - the output is restricted to just 1160 bhp, although that’s still good for 852bhp per tonne.
