I set the car into its "Track" mode, tightened my grip on the steering wheel and unleashed the full 707 horsepower. The 275/40ZR-20 Pirelli's didn't have a chance, and squealed in pain as the Hellcat clocked its 0-60 time of 3.4 seconds. Although you can take control of your gear changes with the wheel mounted paddles, the transmission is best left in automatic mode. This is not testament to the programming of the automatic 'box, more so the fact that when in manual mode, often the transmission will deny you a downshift when you really want one and is generally slow to react.
