Haha I didn't think people still retained that ancient knowledge of motoring success. The good ole days of weak 4-cylinder cars and trucks, when you'd disengage the AC to get more power to go up a hill or something. I've met several people who didn't know it was even a thing.
Yes of course they are, but modern 4-cylinder engines have advanced a lot since the old days of last century's engines.
Today it's not hard to find a 4-cylinder that can put out 100 horsepower per liter, or even more. They can pull that little car up the hill with the AC on full blast.
