Sure, we already have a supercar that goes over 1,000 horsepower with the Bugatti Veyron, but is the Bugatti green in any which way? Yeah right. We'd like to introduce you to the Koenigsegg Agera R, a 1,140-horsepower hypercar that reaches 273 mph running on E85 and E100 biofuel. The Agera and Agera R also have the world's first nano-surfaced cylinder sleeves used in production engines, supercharged 5-liter V8s in their case. Koenigsegg bumped up the rev limiter from 7250rpm to 7500rpm for the additional power. The most unique feature isn't under the hood, though, it's under the tires. The company created the world’s first hollow, one-piece carbon fiber wheel, providing a huge decrease in unnecessary mass while maintaining strength and safety. Bow to the new king.
