Understanding Challenger Performance Pages and UConnect Data

What Are Performance Pages?

Performance Pages are a built-in application on the UConnect infotainment system in Scat Pack, SRT, and Hellcat Challengers. Accessed through the UConnect menu, they provide real-time data displays, performance timers, and vehicle telemetry that used to require expensive standalone equipment.

Not all trims have Performance Pages — they're specific to the SRT-branded and performance-oriented configurations.

Available Data Displays

G-Meter: A real-time lateral and longitudinal G-force display. Shows body motion during acceleration, braking, and cornering. Useful for understanding how hard you're actually driving and for comparing before/after modification results.

0–60 Timer: Automatically detects standing start acceleration and records your 0–60 mph time. The system uses wheel speed sensors for accuracy. Stand still, press the activation button, accelerate hard, and the screen displays your time when you reach 60 mph.

Quarter Mile Timer: Same principle as the 0–60 timer but measures elapsed time and speed at 1/4 mile. Results are displayed alongside your reaction time (time from launch to when the car begins moving). This is your on-road approximation of a drag strip result — not perfectly comparable to a properly timed strip but useful for comparing car-to-car or tune-to-tune.

Horsepower/Torque Meter: Estimated real-time power output based on acceleration and vehicle weight. Note: this is a calculated estimate, not a true measurement. It's interesting to watch but shouldn't be compared directly to dyno results.

Oil and Coolant Temperature: Critical gauges for any performance driving. On a modified car or during track use, watch coolant temp particularly — if it climbs above 230°F, back off.

Boost Pressure (Hellcat only): The Hellcat's 6.2L supercharger outputs up to 11.6 psi of boost. The boost gauge is real-time and accurate — you can see boost building through each gear pull.

Intake Air Temperature (IAT): Shows inlet air temperature. On a hot day or after several hard pulls (heat soak), watch IAT climb. Above 110–120°F IAT, the PCM begins pulling timing. This is where an upgraded intercooler (on the Hellcat) or a cold air intake (on NA models) pays off.

Getting the Most From Your Timers

For accurate 0–60 and quarter mile times:

1. Warm the engine and transmission fully
2. Use Track Mode to disable stability intervention
3. Ensure tires are properly inflated and warm
4. On a flat, level surface
5. Take multiple runs and average — single runs vary due to traction variables

The quarter mile timer is useful for comparing the effect of modifications on the same car on the same day — consistent conditions make the relative comparison valuable even if the absolute time isn't drag-strip-accurate.
