NASCAR Digital Dashboards

While it may not be common knowledge, NASCAR race cars do not have many of the dashboard features common to road vehicles. One such feature NASCAR cars lack is speedometers. If NASCAR vehicles don’t have speedometers on their dashboards, then what do they have? The dashboard on all NASCAR cars was changed in 2015 from using analog gauges to utilizing the current digital display that can be fully customized by each team.

What are NASCAR Digital Dashboards?

NASCAR digital dashboards can display data on sixteen different pages in the form of numbers, graphs, color scales, or digital imitations of traditional gauges. All of the displays are manufactured by McLaren, and their proper name is the McLaren Digital Dash. Teams have as many as 30 digital dashboards available for use at a time. Beside the dashboard is a screen showing the view from a rear-facing camera so drivers can see behind them. However, one thing that NASCAR’s digital dashboards don’t show is the car’s speed.

Digital Display Information

There are many technical readings that can be displayed on these screens. Here are the main pieces of information shown on NASCAR digital dashboards:

  • RPM
  • Lap time
  • Water temperature
  • Water pressure
  • Oil temperature
  • Oil pressure
  • Fuel pressure
  • Voltage
  • Pit road lights

Pit Road Lights

NASCAR digital dashboards feature a set of lights that drivers use to prevent speeding on pit road. There are several sets of lights (green, yellow, orange, and red), and they function like a simple tachometer. Pit road speed is different for every track, so teams calibrate the pit road lights for each upcoming race. The green lights mean the driver is going too slow, and the yellow and orange lights mean they are within the pit road speed limit. Red lights mean they are over the speed limit and need to slow down.
