The Koenigsegg Agera RS is in a class of its own. Christian von Koenigsegg's creation features an aluminum-reinforced, 100% carbon fibre chassis, which gives it a weight-to-power ratio that's hard to match. Its twin-turbo, 5.0-litre V8 engine develops an astronomical 1160 horsepower and works in tandem with a seven-speed automatic transmission. The high-end hybrid Regera's output is in the 1500-hp range. Better than nothing, I guess.
