Whay did Honda stop making the Insight?
 

Has anything come even close to the mpg it was getting?

Well for starters it looked terrible. It just wasn't a great car. Try the prius. It gets really good gas and though it looks like a trapazoid going down the road, it's very reliable and looks better than that little hunk of crap "insight".

Actually Honda made a huge loss out of every Insight sold. The purpose of that car was probably both promotional and r&d. They also make overtime r&d about alternative propulsion systems like fuel cell or hybrid, but they may prefer not to go commercial. The FCX experimental fuel cell vehicle was also an experiment, an r&d project, but the retail was limited to only a few fleets in Japan. Insight was actually a research program. It was an extreme car despite the practicality. Now it's starting to become pointless because there's significant improvement in gasoline engines and non-hybrid cars neared Insight in terms of consumption.
