April 22, 2014—Although electric vehicle sales are up 21.8 percent year over year, lack of proper infrastructure is the biggest limitation for mass adoption of electric vehicles, according to a new study from Cars.com.

“Many consumers living in metropolitan areas would like to get an EV, but aren't able to for reasons like not being able to charge it in their apartment complex garage or lack of nearby charging stations,” said Jesse Toprak, chief analyst for Cars.com. “Ultimately, mass adoption will require sufficient infrastructure to be in place, and we aren't quite there yet."

Top electric vehicle sales year to date include the Nissan Leaf, Tesla Model S, Chevrolet Volt, Toyota Prius PHV and the Ford Fusion Energi.

The Lincoln MKZ, Hyundai Sonata, Lexus CT200h, and Kia Optima Hybrid are leading the hybrid segment with the biggest increases in 2014. 

“It appears the increased fuel efficiency of regular gas engine vehicles, as well the rising popularity of pure EVs has made a dent in demand for hybrids," said Toprak. "Some early adopters are now opting for EVs because they feel hybrids aren't as eco-friendly as the pure EV alternatives available. Regardless, hybrids are here to stay and are still the most practical option for the majority of environmentally conscious consumers."
