It’s hard not to feel some sympathy for Ford’s communication department. The team forgot to delete a few features that aren’t actually available to the Mach 1, and it has ended up costing Ford Australia quite a bit.

The automaker wrote in promotional material that some items like radar-guided cruise control, rear parking sensors and fog lamps would be available on the Mach 1, reports Car Advice. Unfortunately, that’s not the case.

“We recently discovered some content and feature corrections on the Mustang Mach 1 for the Australian market, and are disappointed we didn’t catch this before the first run of brochures and website was published,” Ford Australia wrote in a statement. “We are especially disappointed that our loyal Ford customers and Mach 1 owners feel let down.”

Thanks to the Mach 1’s numerous aerodynamic upgrades, the same upgrades that make it one of the fastest naturally aspirated Mustangs ever, it cannot be had with those features.

Certain “uniquely engineered parts, which are designed to improve downforce and cooling on the Mach 1, unfortunately mean that the vehicle does not feature (radar cruise control) or audible rear sensors while parking, though a reversing camera remains standard,” the company noted.

Ford is calling the error a simple oversight and has promised it will attempt to make up for the mistake. The company is offering three years of free scheduled servicing (at 15,000 km/12 months, 30,000km/24 months, 45,000/36 months), as well as a free track day at one of a number of locations around the country.

In all, Car Advice estimates that it will cost the company more than $1 million AUD ($784,000 USD). That despite only 700 Mach 1s being allocated to Australia.

Ford is reaching out to customers personally to give them details on the reimbursement program and says it will change all future communications regarding the car.
