 Live telemetry is used only for television broadcasts, but the data can be recorded from the ECU to the computer if the car is in the garage and not on the track.The cars are powered by naturally-aspirated (no turbocharger or supercharger) direct fuel injection (since 2014) inline-4 engines, with aluminium alloy blocks, and a DOHC valvetrain actuating four-valves per cylinder, and limited to displacement since the series' inauguration in 2012.DTM car's engines are currently producing over power output between 5,000-7,400 rpm.
