All these risks for a 1-1.5 mpg gain. The successor to this technology, DFM is more advanced, but the Camaro did not receive it, and you know how it is with complexity in general, the higher it gets for a component, the more prone it is to fail. |
DFM sounds interesting, the gist of it to me sounds like deactivation of any amount of cylinders based on the pedal input. Though as you said, there’s no trust in these concepts for me at least anymore so I wouldn’t get anything that has it especially this early on. Maybe I’m just biased but who knows if owners of those cars get run around for a fix like us
