Honda is in the midst of debuting concept car after concept car at the 2011 Tokyo Motor Show. Their latest unveiling came in the form of a plug-in hybrid sedan dubbed the AC-X concept. The AC-X (Advanced Cruiser Experience) concept has been described by the automaker as "it offers a comfortable and enjoyable driving experience in urban and long-distance motoring." By first glance, it would appear to do so and add some slick styling to boot.

Honda has also added some futuristic technology to its AC-X, equipping something called "automatic driving mode." Details of the new tech are scarce, however it is meant to reduce physical driving stress. They claim to have tested this new system on some of their old F1 vehicles and say it cuts a few seconds off their lap times. As previously mentioned, the plug-in hybrid technology added should help the new sedan maintain good fuel-efficiency numbers. It is equipped with a 1.6-liter 4-cylinder engine paired with two electric motors. Electric range for the concept is measured at 31 miles and when in the EV mode, can hit a top speed of 62mph.

The new Honda AC-X concept might be a pre-production version, as the Japanese automaker has already committed to releasing some plug-in hybrids in the forthcoming year. If this new sedan turns out to be the new production model, it's safe to say prospective customers will be pretty satisfied. Photos displayed are of the 2011 Honda AC-X Concept.
