Ford could be preparing an exciting new addition to its seventh-generation Mustang lineup, with reports suggesting that a GT350-inspired performance model is currently in development. Expected to arrive for the 2028 model year, the rumored Mustang could revive the formula that made the previous Shelby GT350 special: a high-revving naturally aspirated V8, a six-speed manual transmission, and track-focused engineering.
According to reporting from Ford Authority, the upcoming model could slot between the 500-horsepower Mustang Dark Horse and the supercharged Dark Horse SC. However, it remains unclear whether Ford intends to revive the Shelby GT350 name or introduce the car under a different performance designation.
Naturally Aspirated V8 Power
The biggest attraction could be a naturally aspirated V8 displacing either 5.2 or 5.4 liters. While Ford has not confirmed the engine configuration, speculation has centered on a potential revival of the 5.2-liter Voodoo architecture used in the previous Shelby GT350.
That engine produced 526 horsepower and 429 lb-ft of torque, featuring a distinctive flat-plane crankshaft and an 8,250-rpm redline. A successor could potentially deliver between 600 and 650 horsepower, although no official output figures are available.
Unlike the Dark Horse SC’s supercharged powerplant, the rumored model would reportedly prioritize naturally aspirated responsiveness and high-revving performance.
Six-Speed Manual and Track-Focused Upgrades
Enthusiasts will also appreciate reports of a Tremec six-speed manual transmission. The combination of rear-wheel drive and a naturally aspirated V8 would give the Mustang a distinctly traditional performance character.
Additional upgrades reportedly include larger brakes, improved cooling, revised suspension components, and wider bodywork inspired by the Dark Horse SC. The model is also expected to be offered exclusively as a fastback coupe.
These changes suggest Ford is targeting sustained circuit performance rather than simply increasing straight-line acceleration.
2028 Launch and Possible Pricing
Ford Authority’s reporting points toward a late-2027 introduction, with the vehicle expected to arrive as a 2028 model. A starting price around $80,000 has been suggested, although this remains speculative.
Another possibility is the Dark Horse Boss name, following Ford’s trademark activity involving the historic Mustang designation. However, there is no confirmation that this name will be used for the rumored GT350 successor.
Ford has yet to officially announce the vehicle, its specifications, or its production plans.
If the reports prove accurate, the upcoming Mustang could fill an important gap in Ford’s performance lineup. A naturally aspirated V8, manual gearbox, and track-oriented chassis would offer something increasingly uncommon in today’s high-performance market: an uncompromising driver’s car built around mechanical engagement rather than forced induction alone.
