How did the Challenger SRT Demon Go Faster Than the Model S?

The Dodge Challenger SRT Demon may not do corners very well, but that’s not what it was engineered to do. In fact, the only objective the guys at Dodge had for it was to be fast in a straight line.

Specifically, they wanted the Challenger SRT Demon to be the world’s fastest production car to run the quarter mile.

And to do that, they had to beat one very tough, very MODERN contender – the Tesla Model S P100D.



The P100D gets to the quarter mile in 10.5 seconds. The Dodge Challenger SRT Demon does it in 9.65 seconds. To achieve this, a number of industry first had to be done.

This includes the following:

  • Factory-installed wider, Nitto street-legal drag radials for improved grip, 40 percent more launch force compared with SRT Hellcat tires
  • Available Direct Connection engine controller calibrated for 100+ unleaded high-octane fuel
  • SRT Power Chiller™ redirects air conditioning refrigerant to chill the charger air cooler
  • After-Run Chiller runs the cooling fan and the low-temperature circuit coolant pump after engine shutdown
  • TransBrake locks the output shaft of the TorqueFlite eight-speed automatic transmission to hold the car before launch, allowing the driver to increase engine rpm for higher torque and quicker response
  • Torque Reserve boosts engine air flow and supercharger rpm before launch, delivering wickedly fast acceleration
  • Drag Mode suspension tuning maximises weight transfer to the rear wheels for better traction
  • Drag Mode Launch Assist uses wheel speed sensors to watch for driveline-damaging wheel hop at launch and in milliseconds modifies the engine torque to regain full grip and then continues accelerating the car down the track
  • Available narrow “front runner” wheels for use at drag strips cuts front-end weight
  • Wide-body exterior styling, with concealed wheel well attachments house Challenger SRT Demon’s massively wide 315/40R18 tires
  • Front passenger seat and rear seat deleted to reduce weight
