Honda is reportedly making progress developing a new hybrid powertrain that will make its production debut in the US market.

A test mule spotted by Autocar is presumed to contain the new system, which is said to be related to the Accord Hybrid's powertrain. The latter model combines electric power with a 2.0-liter four-cylinder Atkinson-cycle engine, delivering 212 horsepower and achieving a 48-mpg combined rating.

The latest report suggests the new hybrid setup will be used for a new dedicated model geared for the US market. Unlike the Acura Sport Hybrid systems, the Honda offering is expected to focus on miles per gallon instead of combined power output.

Honda has had a checkered past with hybrids, retiring the Insight in 2014, but CEO Takahiro Hachigo has stated that electric vehicles will be critical moving forward and half of the company's all-new models arriving in the US in the next two years will be electrified.

The new hybrid model could be revealed sometime next year.
