It won't come as a surprise to learn there's been a large increase in the number of diesel-powered and hybrid cars on the road, either due to gasoline price increases or environmental concerns. But the size of the increase may surprise you.
RL Polk compiled information from national vehicle registration data to give a better idea of how many of these cars are out there. For example, clean-diesel registration has increased 24.34% from 2010-2012 (an increase from 640,779 to 796,794).
Hybrid car and SUV registration has increased even more; by 33.58% during the same time (an increase from 1,714,966 to 2,290,903).
