Diesel cars may keep a lower profile than hybrids or battery-electrics, but they're a good option for drivers looking to reliably save fuel.

Many efficiency-focused gasoline cars and some hybrids have achieved stellar window-sticker fuel-economy ratings, only to fall short in the real world.

Diesels generally don't have that problem. In fact, they've been known to exceed EPA-rated highway figures in regular driving.

Thanks to mandated particulate filters and urea injection, today's diesels are also much cleaner than the soot-spewing models many American drivers remember from decades ago.

Below is the Green Car Reports guide to every 2015 and 2016 model-year diesel car and truck on sale in the U.S., with full powertrain specs and fuel economy for each.
