when did ford start using the 6.7 diesel
Ford Power Stroke engine Emissions controls include exhaust gas recirculation, Denoxtronic-based selective catalytic reduction (SCR) from Bosch, and a DPF. Output was originally 390 hp (291 kW) and 735 lb·ft (997 N·m).[6] but shortly after production started, Ford announced that they made an update to the 6.7L diesel. The new engine control software makes the engine capable of 400 hp (298 kW) at 2,800 rpm and 800 lb·ft (1,085 N·m) at 1,600 rpm while achieving better fuel economy and without any physical changes to the engine. [7] The 2015 engines are rated at 440 horsepower (330 kW) and 860 lb·ft (1,166 N·m).[8] Ford claims the bump in horsepower is from a new turbo, new injector nozzles and exhaust improvements. For 2017, the torque has risen to 925 lb·ft (1,254 N·m) at 1800rpm, Horsepower remains the same..[9]
Ford F-Series In 1965, the F-Series was given a significant mid-cycle redesign. A completely new platform, including the "Twin I-Beam" front suspension, was introduced that would be used until 1996 on the F-150 and until 2016 on the F-250/350 4x2. Additionally that year, the Ranger name made its first appearance on a Ford pickup; previously a base model of the Edsel, it was now used to denote a high-level styling package for F-Series pickups.[4]
