Koenigsegg Agera R

Power-to-Weight Ratio: 1,114 hp / 2,844 lbs = .4 0-60 mph: 2.9 seconds Top Speed: 273 mph (unverified) Prepare yourself, for now we enter the realm of the insane. One thousand and one hundred forty-four horsepower is just too much. There is no possible need for humans to have that much power at their fingertips. The only reason for this Swedish freak’s creation is simply to answer the question “Why not?” Running on biofuel, Koenigsegg claims that on special tires the Agera R can hit a ludicrous 440 km/h, or 272.8 mph, although this limit has yet to be officially tested. Featuring an in-house-developed twin-turbo-charged 5.0-liter V8, the Agera has broken six production-car world land speed records, even besting the Veyron's 14.6 second run to 300 km/h by .07 seconds.
