It is not difficult to imagine a similar interaction between the hybrid and the plug-in hybrid. With all the positive attributes of the conventional hybrid, as well as significantly better fuel economy, the plug-in could very well be the midsized SUV of the next decade. If that happens, the plug-in will certainly need a new S-curve of its own, and both auto manufacturers and dealers should be prepared for a faster-than-expected increase in demand. In the meantime, however, we can place confidence in the S-curve’s prediction that the conventional hybrid, regardless of the future path of gas prices, is here to stay.
