A recent patent has revealed that Ford has come up with an unusual way to encourage drivers to save fuel that involves increasing engine noise. Real-world fuel savings are not as high as one might expect given the recent trend of putting downsized and turbocharged engines under the hood, and according to Ford, that’s because most drivers “shift by ear” rather than by the tachometer.
For example, the combination of the Ford Fiesta’s offbeat snarl and turbo boost practically begs its drivers to rev the 1.0-liter EcoBoost 3-cylinder engine. Ford claims that the advantage of downsized turbo engines is negated by this because they aren’t driven within their most efficient range.
To counter this, Ford is injecting low-amplitude noise between cylinder firings that would make engines sound as though they had more cylinders than they do in reality and train the driver to shift earlier. For turbocharged two-cylinder and three-cylinder engines, this should be a way to help drivers save fuel without resorting to invasive solutions like cutting power or artificially limiting RPM, which we expect our customers will appreciate at Highway Ford!
