Manual Shifting Provides More Power

I have a car that has a "Sport Mode" that is supposed to give me more power. It seems like when I shift the gears myself, I get more power than I do in Sport Mode. Is it my imagination or does shifting myself give me more power?

It's not your imagination, Maureen. You're probably getting a little more power by keeping the car in each gear longer. You're certainly getting more noise, and that also contributes to the feeling that you're going faster.

In most standard passenger cars (of which we'll categorize the Hyundai Sonata), there's a button called "Sport Mode" or something like that. Since transmissions are electronically controlled now, that button simply moves the shift points higher. So, under normal circumstances, if the transmission would shift gears at 2,200 rpm, in Sport Mode, it might shift at, say, 2,800 rpm.

Manual Shifting Provides More Power

The higher the engine rpm (up to a point), the more power you get. Also, the lower mileage you get! Which is one reason the car doesn't run in Sport Mode by default. The other reason is the noise. Most people prefer quiet and higher gas mileage to a little zippier acceleration. But if Sport Mode causes the car to shift gears at 2,800 rpm, you can certainly wait longer than that when you do the shifting.

So, if you're shifting at 3,500 or 4,000 rpm, the car is going to feel (and definitely sound) like it's going faster than it does in Sport Mode. If that still doesn't feel fast enough for you, Maureen, try chiseling a hole in your muffler. That'll make it sound like you're flying.
