Built in Georgetown, Kentucky, minor upgrades accompany the Toyota Camry Solara into the 2006 model year. Four-cylinder models increase highway fuel economy by 1 mpg to 33 mpg, thanks in part to a new five-speed automatic transmission with sequential shift mode. All Camry Solaras have power lumbar support for the driver this year, and convertibles get new "donut-style" rear headrests that improve visibility whether the top is raised or lowered. Solara SLE models receive new wood trim for the interior that replaces the reddish tint of the previous decor with a lighter-colored brown hue.
