.....Some manufacturers only offer their plug-in hybrid models in certain markets, even as hybrid models are now generally offered nationwide.
Like electric cars, plug-in hybrid sales are sometimes limited to markets deemed suitably friendly to these types of vehicles by their makers.
But Hyundai has a more ambitious strategy.
It will offer its Sonata Plug-In Hybrid mid-size sedan and Ioniq Plug-In Hybrid everywhere in the U.S.—although a special order may be required in some states.
The Sonata Plug-In Hybrid was introduced in 2015 as a 2016 model, and Hyundai is just now beginning to roll out the Ioniq as a 2017 model.
The Ioniq Plug-In Hybrid will only be actively marketed in the 10 states that share California's emissions standards, but it can be ordered in all 50 states, a source familiar with the matter said.
