Fuel economy (EPA)

U.S. EPA estimates in miles per gallon as currently published on fueleconomy.gov (older models are shown on the revised 2008 EPA method, so they read lower than the original window sticker). To convert: L/100 km = 235.2 ÷ mpg.

Factory colors & paint codes

Swatch colors are approximate screen representations. Always match paint by the color code on your vehicle’s paint label (usually on the driver door jamb or under the hood), not by the swatch. Availability varied by body style, trim and year (U.S. market). Two-tone swatches show the upper color over the lower color.
