With a heritage of performance that dates back over 50 years, Mustang has certainly solidified its spot as an iconic sports car.
In that time, the introduction of the four-cylinder Eco Boost has been the only significant engine change that the manufacturer has seen.
While there are plenty of high-performance V8 Mustang tuning options from the factory and with aftermarket tuners, Shelby's GTE Eco Boost is one of the only packages that has turned the four-cylinder up to eleven.
A new "entry-level" performance variant has reportedly been confirmed by the Ford Motor Company, hinting at the fact that it will become part of the 2020 line-up.
These reports sent the rumour mill into overdrive, and Ford basing the car on the four-cylinder EcoBoost Mustang was a popular theory that emerged.
With only one relatively unknown tuning package currently on the market, an "entry-level" performance EcoBoost has the potential to reach buyers that wouldn't have considered the four-cylinder model.
The performance package that Shelby currently offers for the EcoBoost Mustang includes a cold air intake system, a cat-back exhaust system, and an engine tune that pumps the power up from 231kW to an impressive 257kW.
These power figures line up with those of the Focus RS, and would be something that fans would expect to see in a performance EcoBoost Mustang.
Combining the power increase with the upgraded Michelin tyres and Brembo brakes that are optional for the V8 variant, you'd have an extremely competitive four-cylinder sports car.
Toyota's high-spec 86 and the powerful Nissan 370Z would be the high-performance EcoBoost's rivals.
While it's unknown whether a model like this would ever make it to our shores, the current EcoBoost is priced at $62,990 — $17,000 less than its V8 counterpart.
With less than 100kW over the potential performance EcoBoost package, this potential update could certainly narrow the gap between the four-cylinders and the V8s.
