Yesterday when I was driving home from work I floored the gas pedal of my BMW coming out of a 25mph turn. I was surprised by the sluggish acceleration of the heavy 7 series, which is usually quite agile, thanks to it’s large V8. But yesterday, the car just didn’t feel like it was agile. Then it dawned on me: outside it was 38C and the A/C was working overtime. Both effects took significant power away – enough so I could feel it. That reminded me that I definitely want my next car to be turbo or supercharged.
