What kind of car is the most green, fuel efficient and budget friendly?

A decade ago, drivers who wanted to go green had little choice beyond Toyota's Prius hybrid.

Today the selection of efficient, lower-pollution cars includes a bewildering array of technologies and models — hybrids, plug-in hybrids, battery electrics, diesels and hydrogen fuel cells. Conventional gasoline cars, meanwhile, have made great strides in going farther on less fuel.

But which technology is kindest to the planet? And which one fits your family's budget and your commute?

With the help of the Union of Concerned Scientists, we examined seven powertrain options, analyzing their greenhouse gas emissions — including the power plant pollution required to produce electricity — along with their relative fuel efficiency and cost of operation.

The analysis looked at comparably-sized passenger cars and, where possible, different powertrains fitted into the same model. Costs were based on typical California fuel and electricity prices.
