The all-new Ford Fiesta ST is gaining for the first time ever a mechanical limited-slip differential, along with patented force vectoring springs and Launch Control for the best start on the track.
The US automaker decided to reveal more details about the new generation Fiesta ST, focusing specifically on the technologies that make the new model engaging, fun-to-drive and even fuel efficient. The all-new 200 PS, three-cylinder, 1.5-litre EcoBoost engine comes for the first time with cylinder deactivation in a bid to improve fuel efficiency by up to 11 percent. Also new for the Fiesta are the selectable Drive Modes – they rework the engine, steering and stability controls for Normal, Sport and Track settings.
The third-generation Fiesta ST is also the first in the subcompact family to receive an optional Quaife LSD, a mechanical system that also works jointly with the automaker’s Torque Vectoring Control technology. Also new are the Ford-patented force vectoring springs for the Fiesta ST’s twist-beam rear suspension. These are non-uniform, non-interchangeable, directionally-wound springs – they also come with a 10 kgs weight reduction compared to the typical Watt’s linkage solution. Also – but this time around developed solely for track use – the Fiesta arrives with the optional Launch control. The new 1.5-litre EcoBoost engine has 200 PS at 6,000 rpm, along with 290 Nm of torque from 1,600 to 4,000 rpm, for a 0-100 km/h (0-62 mph) sprint in 6.5 seconds and a maximum speed of 232 km/h (144 mph).
