Ford's full-size and light-duty (half-ton) trucks for 2003 subdivide into a staggering array of sizes and models. There are cabs for Regular, SuperCab and SuperCrew versions, both short and long wheelbases, Styleside and Flareside exterior designs and chassis rigged with either rear 2WD or 4WD traction. The F-150 Regular Cab carries a bench seat for three, but on XLT and Lariat a 40/60 split bench is available. SuperCab shows an optional 40/60 split rear bench, and SuperCrew has an extra foot in length added at the rear of the cabin to make room for a full-size rear bench seat for three. SuperCrew's pickup box is chopped by 18 inches to keep the truck's overall length manageable when driving. Standard engine for F-150 trucks is a ULEV-compliant 4.2-liter V6 at 202 hp, but there are two V8 options: Ford's 4.6-liter Triton V8 with 231 hp and the 5.4-liter Triton at 260 hp. Alternate fuel F-150 trucks for natural gas, bi-fuel natural gas and bi-fuel propane are also available. The four-door SuperCrew King Ranch provides deluxe features with fine leather lining bucket seats in front and back with optional moonroof and video entertainment system. The new Heritage edition F-150 marks a hundred years in trucks for Ford and F-150 STX in a new value package applies a monochromatic color with 17-inch wheels and the interior with a premium audio system for CD and MP3 functions. A heated rear window is standard on Lariat and King Ranch SuperCrew models, with deluxe Imola leather-trimmed seats optional in SuperCrew. Burgundy Red Clearcoat Metallic is one of several new exterior shades for F-150.
