As the 2006 Civic Hybrid is a very updated version, it looks like I'll need to add this as second-generation. Also, is the Mariner on the roads yet?

 

Am I wrong ? I thought a mariner was a 'fancy interior' FEH.

 

I think his point is that it's not an option in the database, but it's soon to be for sale. The idea is that every hybrid for sale is in the database. The Lexus 400h is just a fancy interior Highlander, but they both get entries in the database.

 

It's important to note what the capabilities of the database are. Even if two hybrids were _exactly_ the same... EXACTLY... yet different demographics bought the respective cars, we'd want to separate them. This way, we'd be able to see what a likely driver for a given model would be likely to achieve.

That said, there are actually some changes than can affect fuel economy. Weight, shape, (power?), etc.
