New environmental requirements are the reason for the horsepower drop in the Ford Mustang GT and Mustang Mach 1.

Ford Mustang Marketing Manager Jim Owens explained why the 2022 Mustang GT and Mustang Mach 1 both lost 10 horsepower each, according to Muscle Cars and Trucks.

We are talking about the 5.0-liter Coyote V8s in the Mach-1 and GT. The engines have slightly reduced power and torque. The automaker has met the new CARB Low Emission Vehicle III requirements, Owens said.

It is clear that some owners of ‘hot’ Mustangs dislike this news, but, as the top manager added, they “gotta be compliant to sell…” Owens believes that you won’t feel the difference in performance “unless you’re a 10/10 driver.”

For those who want to return that power to their Coyote engines for the 2022 Mustang or significantly exceed it, there are several completely legal aftermarket solutions, the specialist noted. Specifically, Ford Performance offers supercharger kits that are warranted and fitted by a dealer.

In 2012, CARB adopted Low Emission Vehicle (LEV) III regulation as part of the Advanced Clean Cars regulation package, which also includes the state’s zero-emission vehicle (ZEV) regulation. LEV III regulations include increasingly stringent emission standards for both pollutants and greenhouse gases for new passenger cars through the model year 2025.

Let’s recall that Ford Motor Company reduced the rated power of both 2022 Mustang GT and 2022 Mustang Mach last fall. This decision followed after EPA demands for derating the 5.0-liter Coyote V8 engines. As a result, the power of the 2022 Ford Mustang GT is increased to 450 horsepower, and the power of the 2022 Ford Mustang Mach 1 is increased to 470 horsepower. That is, minus 10 hp on each model.
