New front-end styling and many new features go into full-size Silverado LD (light-duty) trucks for 2003. The series has pickups in 1500 and 2500 weight classes with various cab sizes, plus short or long box and standard Fleetside body styling or rakish Sportside on 1500 Silverados. The aggressive new face features strong horizontal lines, bold multi-lens headlamp clusters and a thick air dam fixed with corner foglamps. Side panels show flared and squared wheelwells with large wheels and new protective body-side moldings. Cabs have optional new dual-zone climate controls and redesigned seats. Seating for the Regular Cab is a bench for three split in 40/20/40 sections. For the Extended Cab, bench or buckets stand in front of a back bench with padded back tilted for comfort. One four-door format has two rear-hinged doors for easy entry to the rear. Engines begin with a 4.3-liter V6 with 200 hp for Regular Cab. The Extended Cab brings a 4.8-liter V8 and 270 hp channeled through an automatic transmission. Silverado's 5.3-liter V8 reaches 285 hp, while the top V8 runs to 6.0 liters and 300 hp. Deluxe LT Silverado totes an automatic active transfer case -- called Autotrac -- but it's available on LS trim. Another system labeled Insta-Trac permits shift-on-the-fly switching from rear-wheel to four-wheel mode and has a 4WD low gear for off-road work. The option of four-wheel-steering (4WS) extends to 1500 HD short-box trucks with the Quadrasteer system that dramatically reduces the turning circle of a truck and brings improved high-speed stability plus low-speed maneuverability. Other new options range from Bose sound systems to a Panasonic Passenger Entertainment System with DVD player and flip-down screen for Crew Cab, plus subscription-based XM satellite radio service across the board.
