 The problem was it weighed 32 pounds and took 10 horsepower to drive it. So, yeah, when you've got a car only making 150 horsepower and you take 10 horsepower away, I mean, that's a lot. You took 7%, 8% of your horsepower away just to run your air conditioner, which took a lot of fuel. Today's new systems take 2 to 3 horsepower to run, and when they get down to idle mode where they're almost working at all, they take next to nothing.
