The Focus with the new stability control system is on sale at Ford dealerships.
The system first launched on the 2013 Ford Taurus sedan as standard equipment and is now making its way to one of the most affordable cars in the Ford lineup.
Ford spokesman Chris Terry said the new stability control system will start to roll out to other Ford vehicles besides the Taurus and the Focus in the future. But he did not specify which vehicles are next in line for the system.
"The real benefit to drivers is when you yank hard on the wheel to avoid something like a pothole, the system decreases body roll and helps you to maintain vehicle control," Terry said in a phone conversation.
He added: "The great news for consumers is that even if you buy a 'stripper' Focus, you get this."
The new system is "predictive." It uses steering-wheel angle, how fast the steering wheel is turning, vehicle speed and other parameters to preemptively apply stability control before a yaw moment or turning force turns into an actual vehicle spin.
The 2015 Focus has not been rated by the National Highway Traffic Safety Administration.
The Insurance Institute for Highway Safety named the 2015 Focus sedan a Top Safety Pick. The 2015 Focus scored "good" ratings in Institute crash tests and an "acceptable" rating in the small overlap front crash test. The test is designed to replicate what happens when the front corner of a vehicle collides with another vehicle or an object like a tree or utility pole.
Edmunds says: Car shoppers checking out small, affordable vehicles like the Ford Focus will appreciate this safety upgrade.
