The 2012 Lexus CT 200h is greener than almost any other luxury car, but if mpg numbers mean everything you might still want to go with the Prius.
Just like the Prius, the CT 200h features an exhaust-gas recovery system that helps lower emissions and improve fuel economy—and helps reduce the amount the gasoline engine runs in short-trip use.
As with most hybrids, real-world mileage varies widely (and wildly) based on conditions. If you drive the CT hard enough, you can see mileage creep down into the 20s, but we predict most people will achieve averages close to the EPA's 42 mpg city, 41 highway ratings. Over several real-world drives, we've seen results in the upper 30s, and into the mid 40s in very careful driving.
