Most all-electric cars tend to be larger than hybrids and plug-in hybrids. Each type of electric vehicle has a very different mix of car sizes. Over 60% of all-electrics sold in 2016 were large with the Tesla Model S as the best -seller. Only 12% of hybrids were large and 77% were midsize with the Toyota Prius as the best-seller. Of the plug in hybrids, 44% were smaller and 40% were midsize. the Chevy Volt was the best seller in this category. The size mix is presented in the 100% stacked bar chart below:
The data for this chart was copied and pasted from US Department of Energy website. I grouped the types of vehicles sold into small, medium and large to better deliver the message that there is a difference in size mix based on vehicle type. The DOE data had many more classifications (e.g., large cars, standard SUVs). I included the examples of each size category in the series name. These names were quite long and I displayed them in the legend to the right of the chart. I only included the percentages of the bar in the individual segments. I used segment links to contrast the differences in mix. I also added data for all vehicles sold as a comparison.
I added two data rows. The vehicles sold row gives you a sense of the relative size of each market segment. The best seller row provides an example of a vehicle in each segment. This is helpful for the reader who is not familiar with how electrics are split into market segments.
