Adaptive intelligence allows the proven A580 automatic transmission in Charger SRT, Challenger SRT and 300 SRT to respond to drivers' needs. Adaptive intelligence makes the transmission both strong and smart.

SRT transmission calibration engineer Marty Jagoda explains that, during regular operation, the transmission uses sophisticated software and tuning to deliver optimum levels of all-around performance, comfort and fuel economy. However, as the driver begins to push the car, the A580 adapts to know it's playtime.

"The transmission will increase shift RPM and line pressure," explains Jagoda. "It decreases shift speed based on throttle input. If a customer is driving aggressively on the street, over a period of time the customer will notice that the transmission transitions from the comfort side to the performance side."

In a racetrack environment, the effect is more dramatic. In a matter of laps, the transmission will shift fully to the performance side.

"The vehicle will also adapt back to the comfort side as well, but at a much slower rate," Jagoda says.

In Track Mode, the same adaptation philosophy applies. However, the transmission's "minimum floor," or "zero point," is automatically raised.

"Think of it on a scale of zero-to-100," Jagoda explains, "with zero being comfort and 100 being full performance. In track mode, we start you at 50 instead of zero for a more spirited driving experience."

In addition to the transmission adaptation, the A580 also has a curve control gradient calibration that functions the same in all modes. Based on throttle and steering input, the transmission will hold a gear longer instead of upshifting. This feature has benefits on both the racetrack and the street, as RPM are kept in a more desirable area for engine performance.

Each time the car is restarted, the transmission tuning is reset to ensure that drivers receive appropriate transmission response for each drive.
