Think "green car" and we wouldn't hold it against you if the all-electric Renault ZOE and hybrid Toyota Prius instantly sprung to mind but neither of those actually features on the shortlist for 2014's greenest cars.
The California-based Green Car Journal has released the five finalists for the journal's world famous Green Car of the Year and not one all-electric vehicle features.
The five 2014 models include the Audi A6 TDI, BMW 328d, Honda Accord, Mazda3, and Toyota Corolla.
"The diversity of this field of finalists illustrates not only that 'green' has gone mainstream, but also that there is no single approach to achieving ever higher levels of fuel efficiency and environmental performance," says Ron Cogan, editor and publisher of Green Car Journal and CarsOfChange.com.
"There's something for everyone in this year's field of finalists, including clean diesel, high efficiency gasoline, and hybrid/plug-in hybrid power featured in mainstream, sporty, and executive models."
The overall winner will be chosen and awards handed out at the Los Angeles Auto Show later next month, with the winner 'raising the bar in environmental performance' as well as proving its availability to the mass market.
But this shortlist is very much an all-American affair, as the Toyota Corolla isn't offered in the UK as a new car and the four-cylinder, V6, hybrid, and plug-in hybrid versions of the Honda Accord won't be found on European dealer's forecourts.
