Make sure you know the nearest gas station that carries E85 fuel — you'll need it if you want to unlock the full 1,578 horsepower from Koenigsegg's Agera RS replacement, the Jesko. Named after Christian Koenigsegg's father, the Jesko is the world-beating 300 MPH car that Koenigsegg promised. It's based on an updated version of the carbon fiber and aluminum honeycomb monocoque that suspended the Agera RS, with increased dimensions. Koenigsegg's 5.0-liter, twin-turbo V8 makes a return, now with a lighter flat plane crankshaft that allows for a higher redline and an electric motor that spools the turbos for lag-free, near-instant power delivery. The motor is good for 1,262 horsepower on premium fuel and the full 1,578 horsepower and over 1,100 lb-ft of torque on the aforementioned E85 biofuel. A completely in-house designed 9-speed Light Speed Transmission is a quantum leap in tech, allowing for ultra-fast gear changes from any gear to any other gear — a revolutionary design. Koenigsegg has set its own high bar even higher and the rest of the hypercar world is on notice.
