Ram 1500 pickups have changed considerably for the 2006 model year. A new frame, suspension and body mounts are used, and new headlamps provide 22 percent more light intensity. Newly available features include a power-sliding rear window, bucket seats, a full-screen navigation radio and a DVD entertainment system. Four-wheel-drive models have a standard electronic transfer case. Hemi-equipped Rams are the first pickup trucks equipped with fuel-saving cylinder deactivation: the Multi-Displacement System.

Dodge's Ram is available in 1500, 2500 and 3500 versions, which translates to half- , three-quarter- and one-ton ratings, respectively. While the heavy-duty 2500 and 3500 models are intended for serious work, an offshoot of the light-duty 1500 — the 500-horsepower Ram SRT10 — is designed for serious play.

Ram pickups come in regular-cab and four-door Quad Cab body styles. Light-duty Rams can have V-6, V-8 or V-10 power, while heavy-duty models can have V-8 or diesel power. A sunroof is available on Quad Cab models, and Sirius Satellite Radio is offered.

Ram 3500 powertrains are similar to the 2500 series, which means buyers have a choice of a 330-hp, 5.7-liter Hemi V-8 or a 5.9-liter inline-six-cylinder Cummins diesel. Three transmissions — a six-speed manual and two automatics — are available. Regular-cab Ram 3500 models have dual rear wheels, but Quad Cab pickups can have either single or dual rear wheels.
