More power and better MPG, how is this possible?
How can you improve MPG? Not with full throttle and badass driving. Other than that, it is pretty simple. Your automatic transmission shifts to the next higher gear when a certain torque level is reached (on manuals the driver shifts when having enough torque). When you increase the torque of your engine along the whole rpm range, what happens? Correct, you shift earlier to the next higher gear. Earlier means at lower rpms. The lower the rpms, the less fuel you need. This means, if you drive at lower average rpm, your MPG will increase. That’s also the reason why the MPG improvement is higher with tuned diesel cars (the torque gain is higher with diesel engines).
Let’s be honest: If you drive fast and NOT at lower average rpms you won’t save fuel.
