2016 Volvo S90 – Power Pulse
 |  compressor without dryer |
 powerpulse air from filter |  powerpulse spool up |
The PowerPulse system works by drawing fresh air directly from the air box and compressing it into a two-liter tank. If the driver presses hard on the accelerator at low speeds or even at launch, the compressed air from the tank will be blown through a valve directed at the turbo.
