May triumphs as another amazing month for the EV segment, and it's not even the middle of the year.

Q2 2018 should prove incredible and it only stands to get better from here. By December, growth should be remarkable. For the month, an estimated grand total of 24,560 plug-in electric vehicles were sold. This moves the month into the number four spot overall historically for U.S. EV sales.

The Tesla Model 3 topped our chart once again with a whopping 6,250 estimated deliveries. This makes it five months in a row that the Model 3 has been the leader, and May's numbers set another all-time record. We assume that it will not leave that top position at any point in the foreseeable future and will continue to set and break records month after month. June should be pretty fantastic, however, many people still believe that Tesla will do everything it can to remain under the 200k mark prior to July. We'll see how that all pans out soon enough and will be providing you with more related information in the near future.

The Toyota Prius Prime breaks its own all-time record and continues to hold the second-place position for the month and the year, with 2,924 sold. The Chevrolet Volt grabs up the third position for May based on our estimates (1,675), however, it's not enough to push it into the top five on the year. Chevrolet Bolt sales were down again and at a low point for 2018 as inventories are drying up, more Bolt EVs were delivered to South Korea, and GM is preparing for another model year switch. Our estimates put the Bolt in the seventh spot for May (1,125), though it still remains in fifth for the year as a whole.

Overall for the year, the Tesla Model S and Model X land in the third and fourth positions on our chart after both met expectations with a decent sales month (5th and 6th for May, respectively). According to our research, Tesla sold an estimated 1,520 Model S sedans and 1,450 Model X SUVs.

The Nissan LEAF and Honda Clarity PHEV were the only other vehicles to sell over 1,000 copies in May. LEAF sales spiked significantly (1,576), driving it up to the fourth position for May. Additionally, this was the best showing for the LEAF since December of 2016. The Clarity keeps pushing along pretty incredibly, to say the least. Honda delivered 1,639 Clarity Plug-in Hybrids last month, putting it in the fourth spot on our chart for the month of May.

Until next month, we'll leave you with some other compelling data and another look at the final chart.
