2015 Volvo S60: Finding the Meaning of the Power Meter
by Carlos Lago, Road Test Editor on November 18, 2015
What does this gauge mean? I spent the weekend in our 2015 Volvo S60 trying to figure that out. It says "Power" — which I take to mean a good thing — but it offers no other identifying information. No other text or numbers.
There are just two elements: A yellow line on the left and the yellow arrow on the right. Oh, and they move. The non-descriptive nature reminds me of the boost gauges you'd see in old Saabs. They didn't show psi in numbers; the needle simply went from white to red.
I took this picture of the S60's gauge while blipping the throttle. The arrow jumps when you do this, but the line only moves when the car does. When it does, the line always chases the arrow. What does this mean? Enter the owner's manual.
On page 130, manual outlines the Power Meter.
Apparently, the arrow on the right shows available power. "The higher the reading on the scale, the greater the amount of power remaining in the current gear," the manual says. While the yellow line shows how much power you are using, "the larger the gap between the two indicators, the greater the amount of power remaining," the manual continues.
This is great at explaining what the gauge shows, but I still have trouble finding the purpose. The arrow and line dance around when you hit the gas, but to dubious effect.
To be fair, Rolls Royce does the same thing. The needle goes to 100 percent when you turn the car on and dips when you apply the throttle.
What would I rather have? A boost gauge. With indicated psi.
