For fellow that is hunting for Honda Civic FD 1.8S or 2.0S. You may think that 2.0S model is always better than the 1.8S model from the aspect of pricing and specification.

However, this concept is definitely a big wrong. The R18A engine that fitted on the 1.8S model is one of the most efficient engine that Honda ever built. In fact, the efficiency is even better than the K20A from the Type R.

In engineering point of view, natural aspirated engine that runs efficiently at all RPMs is the finest art. To achieve the efficiencies, this engine is designed using many technologies during the engineering stage. That's where the Honda's engineers expert in.

Check out the video clip that illustrate how the i-VTEC works for the R18A.
