Ford appears to be preparing another high-performance Mustang, with dealer documents reportedly pointing to a late 2027 launch for a new variant that will arrive as a 2028 model.
According to a report by Ford Authority, production is expected to continue only through the 2029 model year, suggesting a relatively short run.

While Ford has not confirmed its identity, this is likely to be the Mustang Shelby GT350 successor. It is expected to sit between the Dark Horse and the more powerful Dark Horse SC, with a clear focus on track driving.
The new model is said to get wide-body styling similar to the Dark Horse SC, but the mechanical package will be quite different. Instead of the SC’s supercharged 5.2-litre V8, it is expected to use a naturally aspirated V8, potentially displacing 5.2 or 5.4 litres. A manual gearbox is also likely, although an automatic option has not been ruled out.

Power could be around 650 hp, but that figure remains unconfirmed. The new Mustang is expected to be offered exclusively as a coupe, with no convertible version planned.
