Does ford f150 v8 have active fuel management. Even the 390 horsepower 50 v8 that ford offers in the f 150 gets slightly better mpg and is just as powerful as the 35l ecoboost v6 and they both have nearly identical 0 60 times. Its similar to the setup in the 2018 silverado and can either run the truck on four or eight cylinders. While ford is using turbochargers in its ecoboost engines to make small engines produce big engine power gm is using active fuel management cylinder deactivation to make its big ecotec3 engines.
Gms system does a good job of boosting fuel economy during the epas testing cycle but in the real world. Over the years gm has taken some lumps from critics. And the companys.
Ford the company that only sells its compact ranger with a four cylinder and whose flagship f 150 engine is a twin turbo v6 has created a new 73 liter v 8with pushrods. The base 53 liter v 8 uses an active fuel management system that deactivates cylinders to conserve fuel. 2004 ford f250 xlt 54l 4x4 gas hello i know chevy has afm.
Variable valve timing accomplishes the same basic effect. The new setup also on the 62 liter v 8 uses what chevy is calling dynamic fuel management. See your ford or lincoln dealer for complete details and qualifications.
In my opinion its because cylinder deactivation is incredibly over rated. Your fuel tank needs both fuel and fumes for your engine to work most efficiently. Im not sure if ford has the same technology.
For those folks that do not know what afm is when coasting on the highway your engine shuts down form 8 cylinders to 4 cylinders for better fuel economy. I would like to buy a after market kit if it exists to convert my engine to use this technology. Why is it that ford has an all aluminum f 150 with the ecoboost 35l v6 and has much worse performance and worse gas mileage then the v8.
Active fuel management formerly known as displacement on demand dod is a trademarked name for the automobile variable displacement technology from general motorsit allows a v6 or v8 engine to turn off half of the cylinders under light load conditions to improve fuel economyestimated performance on epa tests show a 5575 improvement in fuel economy.
