So far, FCA hasn’t seen fit to fit the Durango with the 475-hp 6.4-liter V-8 that powers the Jeep Grand Cherokee SRT, though rumors of a pending Durango SRT persist. For now, at least, its maker proudly postures the Durango as the Dodge Charger of the SUV segment, and the R/T edition is as racy as this model line gets with a 5.7-liter Hemi V-8 in place of the standard, 295-hp 3.6-liter V-6, in combination with a ZF-designed eight-speed Torqueflite automatic transmission. The venerable Hemi appellation describes a Mexico-made 360-hp V-8 with a mix of rustic and recent technologies. The deep-skirt block is cast iron. Aluminum cylinder heads (lacking any hint of hemisphere in their combustion chambers) support a pushrod valvetrain blessed with variable valve timing, port fuel injection, and cylinder deactivation during light-load cruising to maximize EPA-rated mpg.
