Sources Say: Ford F-150’s 4.8L V8 To Feature Dual Injection, Replace 5.0L Coyote

Should the refreshed, 2018 Ford F-150 and 2018 Ford Mustang bow at next month’s Detroit North American International Auto Show as we’re expecting, both cars might have the same new, normally-aspirated 4.8-liter V8 wedged under their hoods.

The engine, which was alluded to during discussions of the new labor contract between Unifor and Ford Canada, will outright replace the 5.0-liter “Coyote” V8 currently found in both the Ford F-150 and Mustang GT, according to an unnamed source. The same source tells us that this new engine will feature dual injection – that is, both direct and port fuel injection – to achieve greater efficiency than the outgoing 5.0L.

Direct-injected engines tend to have greater resistance to knock than those that are port-injected. The combination of both dual injection, and variable valve timing like that found on the Coyote, should permit a higher compression ratio than the Coyote’s respectable 11.0:1. With higher compression generally comes more power, meaning that the new 4.8L could well outperform the 5.0, despite its slightly smaller displacement.

The 5.0-liter Coyote V8 engine is the first Ford V8 to feature Twin Independent Variable Cam Timing (Ti-VCT), which allows the intake and exhaust valves to advance or retard independently of each other for greater efficiency. It’s assembled at the Essex Engine Plant in Windsor, Ontario, where the 4.8-liter is slated to enter production soon.

That the 4.8-liter will replace Ford’s Coyote in both the Ford F-150 and Mustang GT comes as no surprise, of course. That it will feature dual injection for greater efficiency is just good sense.

  1. Glad to see them keeping and upgrading the V8…..the indirect and direct injection…should solve the intake valve carbon build up …that was a costly problem on ecoboost engines,,,

  2. Let’s be real guys, this really isn’t that big of a deal. Ford’s 289ci V8 was a marvelous engine and honestly it fits in the direction that the muscle cars are going. Lets think for a second how good ford has done with the coyote & voodoo engine along with the ecoboost program, now combine elements of the three. An excellent mod-motor based naturally aspirated v8 engine with the induction system from the GT350, a set of heads and cams similar to the GT500 setup but for a cross plane firing order, dual injection, a GT350 style exhaust system from the headers to the dual mode mufflers and quad tips, a 10-speed automatic transmission, better gearing, a brembo brake package magnetic ride and all of the other features that are becoming more and more standard on the modern muscle cars and you’ll have a 475+hp naturally aspirated v8 with nearly 30mpg, improved overall balance and handling and an updated styling that will rival the Camaro as it always has. I don’t feel any negatives about this. This is as close as it’s gong to get to the ’60’s era guys!!! 289HiPo mustangs, Lt1 Camaros, Challenger T/As and Charger Daytonas all running around on the streets again. This is where it’s at! KUDOS to the American big three!!! You guys have made me proud! God Bless America. Merry Christmas to the whole Muscle car nation!

    • The engine would not have the same displacement as a 289 but rather 292ci, which is similar in size to the old Ford Y block engines of the late 50s and early 60s.
