Hold onto something because Hennessey has delivered a knock-out punch.
Enter, the HPE1000 Twin-Turbo/Supercharged Dodge Challenger SRT Hellcat. OH-MY-GOD, this thing hurts me just looking at it. For those in doubt, yes you read that correctly... this thing has strapped on twin-turbos to add to the already ferocious power of the supercharged Hellcat catapult.
1032hp (770kW) is the new magic number and 989lb.-ft (1341Nm) of torque adding up to 15 pounds of extra boost to its existing power. It's also received a water-to-air intercooler, new fuel system and added calibration to the engine and chassis to balance all the new power out... that is if by "balance", you mean 0-100 kph in 2.7 seconds and the ¼ mile in 9.9 seconds @ 227 kph... oh, ooh sorry, I have to sit down.
