Big news for a big truck. The 2007 Dodge Ram Pickup 2500 gets a new 6.7-liter Cummins turbodiesel I6 engine that will hit 350-hp with 650 lb-ft of torque. This replaces the old 5.9 Cummins turbodiesel, though a few 2007 Ram 2500s will feature this engine as the 6.7 won't be ready until a few months into 2007. The more powerful engine also gets a new 6-speed automatic to replace the old 4-speed. The standard engine on all of the 2007 Dodge Ram 2500s will remain the 5.7-liter Hemi V8 at 345-hp, paired with a standard 6-speed manual or optional 5-speed automatic. Also new for 2007 is an exhaust brake, the first of its kind, meant to improve stability and overall hauling power.

The only other change for 2007 is a new optional remote start feature across the line. The 2007 Ram 2500 comes in Regular cab with one row of seats, Quad cab with two rows, and Mega Cab, which is the same length as the Quad, but devotes more room to the spacious cabin than to the 6.3-foot cargo bed. Six people can sit comfortably in the Mega Cab, which features reclining rear seats (and best-in-class 44.2-inches of legroom)and 71 cubic feet of cargo room when the seats are folded flat. The Mega only comes with a short bed, and the Regular cab only with the long 8-foot bed. The Quad cab gives you a choice of either size. All models are available in rear-wheel or 4-wheel drive. There are three trim levels. ST is the most basic, while SLT adds power features and cruise control. The Laramie provides leather seats, power driver's seat, a 6-CD player, power pedals, and wheel-mounted controls.

The 2007 Ram 2500 also offers a Power Wagon in both the regular and Quad cab styles. This carries the Hemi V8 and is geared primarily to off-roading. A stiffer suspension, 33-inch tires and 17-inch wheels, electronic roll bar, and electronic front and rear differentials are its primary characteristics. Skid plates and a 12,0000-pound winch are also standard. With the extra engine power, that's also cleaner and quieter, the 2007 Ram Pickup 2500 should be a big sell. The comfortable cabin is also liked by a lot of owners. Poor gas mileage and somewhat cheap interior materials are drawbacks.
