Do you get better gas mileage with overdrive on or off?
No, it actually burns LESS gas, and that’s part of the point. Overdrive means that for every revolution of the engine, the wheels will turn greater than one revolution. This allows for travel at higher speeds while keeping engine RPM down. Engines burn more fuel at higher rpm.
What does an overdrive button do?
Overdrive allows the engine to operate at a lower RPM for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway. Overdrive should usually be selected when the average speed is above 70 km/h (40-45 mph).
Which is easier to drive, Prizm or DOHC?
The prizm motor is smoother and easier to drive (nice DOHC motor, yes it matters) than many cars in this price range, and should hold up a lot longer. Handling- could be quicker and more assured but i think part of it is the cheap tires. Lights- are your daytime running lights switching to full power at night?
Is the Chevy PRIZM a second class car?
Just cause the Prizm has the Chevy badge does not automatically mean it is a second class product. I suppose the Isuzu Rodeo is a piece of crap to most folks and the Honda Passport is all fine. Chevy Prizm is 95% the same as corolla. And is a good car as far as those 95% (important stuff) is concerned.
What happens when you run a motor at higher speeds?
The following information discusses in some detail what happens to the Volts/Hz ratio and also what the motor torque implications are when operating a motor at higher speeds than its nameplate speed. Standard AC motors rated for 60Hz operation may be run at higher frequencies when powered by an AC drive.
Can a motor run at a higher speed than its nameplate?
In general, the answer to the question is yes – a motor can be run at higher than its nameplate speed. However, there is a trade-off between operating at higher speeds and the resulting torque (rotational force) capability of the motor.
