In a still heated marketplace for highly lucrative heavy duty pickups and commercial vehicles, Ford does not intend to be outdone by General Motors and FiatChrysler’s lately launched a new efforts, announcing the power and torque figures for its new 7.V8 petrol of 3 liters for its 2020 models and recalling that significant revisions for 2020 for its Power Stroke diesel V8 also portend to increased power. At a late July media event, Ford revealed the new 7.3-L, which divides the overhead valve layout Ford mostly abandoned years ago for petrol engines, generates 430 hp at 5500 rpm and 475 lb-ft at 4000 rpm.
The characters conveniently slip past the 401 horsepower and 464 lb-ft available from GM’s 6.6-L petrol V8 and 410 hp and 429 lb-ft FCA deals outside with its 6.4-L Hemi V8, each of which, it might no coincidence, are also OHV designs. Joel Beltramo. Ford manager for V8 petrol motors, said the yield to a OHV layout was driven by the greater power and torque available lower in the rpm range. It is the most strong gasoline Super Duty engine, he added. Further, a dyno certified variant generates 350 hp and 468 lb-ft at 3900 rpm. That variant is standard for the 2020 F-450 chassis cab, F-550 and F-600, F-650 and F-750 medium duty trucks, and also the F-53 and F-59 stripped chassis.
The 2020 E Series cutaway van can also benefit from the newest 7.3 litre V8.
Beltramo detailed the durability concentrated particulars Ford engineered into the 7.3-L, including oversize main bearings, a forged steel crankshaft and special coatings for the piston rings, valves and valve seats is borrowed from Ford’s turbocharged motor encounter. And the cast steel rocker arms have nitride roller bearings and a special design that promotes improved oil stream. Oil nozzles cool the bottom of the pistons. The brand new 7.3-L has port fuel injection, variable valve timing and variable displacement oil pump to reduce parasitic losses. The workhorse V8 is going to be standard or optional in a wide range of Ford commercial vehicles that crosses the F-250/350 Super Duty pickups all the way to the F-350 to F-600 chassis trucks along with the earlier mentioned moderate duty and stripped chassis models.
Coinciding with the 2020 launch of the 7.3-L V8 is a brand new 10 speed automatic transmission, the 10R140 TorqShift. Specifically designed to compliment the torque curves of the new petrol V-8 and revised for-2020 Power Stroke turbodiesel V8, the transmission unbelievably packs at the exact same size case as the 6 speed automatic that remains available for some of Ford’s commercial vehicle lineup. And the four additional ratios, the top 3 of that can be overdrives, and associated hardware upgrades bring only a 3.5-lb. Of extra weight when compared to the 6 speed automatic. We have basically taken from the formulation from the F-150 10 speed, said 10 speed transmissions system supervisor Greg Stout, and enlarged it into the Super Duty class.
However, only 7 percent of the new 10R140’s parts are shared with the light duty 10 speed automatic. In addition, he told Automotive Engineering that even though the light duty 10 speed transmission was developed in co-operation with GM, the significant duty variants were engineered separately. Though Ford isn’t yet prepared to make efficacy comparisons between the 10 speed and 6 speed automatics, Stout said there’s a demonstrable improvement out of having four more reports, but the speed of 10 also employs a maximum of just two clutches today, compared to three previously. And the variable displacement oil pump of the new transmission also improves efficiency, he said. Additionally to five new pre engineered transfer approaches which includes eco, tow and slippery modes, the new 10 speed transmission provides for a normal power takeoff when backing up the Power Stroke diesel. Stout said it delivers a best-in class 300 lb-ft, a 20% upgrade over Ford’s 2019 PTO greatest.
