The 2500 and 3500 Dodge Ram Heavy Duty trucks are the newest 3⁄4- and 1-ton offerings on the road. We criticized the 1500 Ram for not having enough power when it was introduced last year with the 5.9L/245-hp as the top engine. Dodge promised more powerful engines for the 2500/3500 platform, and they came through. The base engine is the new 5.7L gasoline V-8 that's not only the most powerful base engine of this group at 345 hp, but revives the historical Hemi name and accompanying hemispherical cylinder head combustion chambers. Next up is the 8.0L gasoline V-10. It's basically a Viper engine with iron heads that makes 310 hp and 450 lb-ft of torque. The first diesel option is a 5.9L I-6 good for 250 hp and 460 lb-ft (specs not shown). It costs around $4700. However, we'd advise spending about $600 more to get the H.O. version of the 5.9 I-6 diesel. This Cummins design offers the most torque of any production pickup engine at 555 lb-ft.
