Swedish hypercar manufacturer Koenigsegg is upping the ante with the introduction of what they claim is the world’s first “megacar”: the One:1. No doubt designed to take aim at the Hennessey Venom GT as the world’s fastest production car, the One:1 is powered by a new 5-liter V8 capable of producing 1,011 lb-ft of torque and 1,341 horsepower; a 1:1 power-to-weight ratio. A dual-clutch seven-speed gearbox and electronic differential, help put that power to the pavement, with a claim that the car will do 0 to 248.5 mph in an eye-watering 20 seconds. All that speed and power, however, is safely harnessed thanks to the Agera R’s 397mm braking system – one which couples 397mm front power-assisted ventilated ceramic discs with six-piston calipers and 380mm ventilated ceramics with four-piston calipers in back – thus allowing the car to come to a full stop from 248.5 mph in just 10 seconds. All six One:1 production models have already been claimed by enthusiasts, so no word on price point.
