We're talking about a possible game changer.
Following the debut of the 2020 Ford Mustang Shelby GT500 and its 5.2-liter supercharged "Predator" V8 with 760 horsepower and 625 lb-ft of torque, you'd think the Blue Oval wouldn't take things any further, at least with the current sixth-generation Mustang. Well, plans change. Although the automaker has not confirmed anything at this time, a quote from Canadian auto union Unifor's national president Jerry Dias and first reported in the Windsor Star claims Ford will bring a 6.8-liter V8 engine to its famed muscle car.
And there's more.
This same engine is also reportedly destined for the Ford F-150. This information came out during a Unifor press conference in late September where Dias specifically mentioned a new 6.8-liter engine will be built at Ford's Windsor plant.
Dias did not provide any additional details other than stating the new engine will be used in "derivatives for the Mustang and F-150" but an engine of that size could potentially be a V10. When reached for comment on the matter, Ford provided the usual it doesn't comment on speculation regarding future products. But let's do some speculating of our own.
In the past, Ford did build a modular 6.8-liter V10 but it was a gas-guzzler and we really don't see how it'd be possible to manufacture in this era. Modifying the current naturally aspirated 5.0-liter Coyote V8 also seems very unlikely. But there is one far more realistic possibility: a downsized version of the pushrod 7.3-liter Godzilla V8 used in the new Super Duty F-250 and F-350 pickups.
It's also available as a crate engine and can fit in the Mustang without a problem. And then there's this crucial piece of information: the 7.3-liter V8 is built at the Windsor plant. The stars are lining up here, but again, Ford is remaining silent on the matter. In all likelihood, if a 6.8-liter V8 were to arrive, it wouldn't be for the current Mustang but rather its successor, a vehicle that's expected to debut for 2022.
The F-150, of course, is all-new for 2021 and currently has six engine options. Adding at least one more wouldn't be shocking. But until Ford makes an official announcement, we'll just have to sit tight and hope for the best.
