🚗 Ford just showed dealers a real four-door Mustang Mach 4 — and it starts under $40K!
The pony car is getting a sedan sibling. Dealers who saw the prototype in Las Vegas said it looks and feels about the size of a Porsche Panamera… but with more rear legroom and a price that undercuts a lot of the competition.
Key details so far:
Expected around the 2029 model year
Likely based on an elongated S650 Mustang platform
Powertrain options could include the 2.3 EcoBoost and 5.0 Coyote V8 (manual possibly available)
Sub-4-second 0-60 claims
Starting price targeted under $40,000
Ford is leaning hard into the Mustang name to bring back a proper American sedan — and it could spark a muscle-sedan rematch with Chevy’s rumored four-door Camaro.
